Introduction

Landscapes that lastOur towns and cities are under pressure, two thirds of the worlds population is expected to live in urban areas by 2030.

Environmental, social and economic demands are making it difficult for us to create healthy, liveable and economically resilient places.

As we strive to improve our urban environments and tackle city pressures it is evident the extent trees and green areas are a significant contributory factor in achieving these aims.

Urban green spaces play the vital roles of the lung in the urban fabric, a counterpoint to modernist developments and surroundings for urban dwellers social well-being.

Green-techs Urban Specifier Guide offers a complete portfolio of products thats will plant, protect and enhance sustainable urbanscapes for future generations.

Trees for the futureThe creations of sustainable urban forestry in recent years has become a key factor for policy makers, planners, landscape designers and architects on the design and creation of all urban development and regeneration projects.

Planting the tree is just the start the importance of the ongoing health of the tree is becoming the fundamental strategy to addressing the balance of modern environmental urban pressure points Storm water & sustainable drainage, micro climates, air quality and CO levels.

Trees are assets which increase in value over time

TestimonialsCommentaries

Civic Trees work with Green-techs urban tree planting systems to create effective planting schemes nationwide. The wide range of products and technical help available allows us to adjust and adapt planting locations to maximise the planting area to benefit and enhance the trees establishment.

Tree planting adds many benefits to the urban landscape yet decreasing funds and lack of space due to services and other utilities, both above and below ground, mean that only well thought out schemes will deliver best value to the client and other stakeholders.

By combining technical expertise in pit construction with good quality tree stock, well planted in a first-class growing medium and backed up by comprehensive aftercare Britains urban forests can maintain their excellent health and vitality keeping our towns and cities beautifully green

Deric Newman, Civic Trees

Trees are a vital part of many of our projects and we consider them at the very beginning of the design process. Correct tree selection then needs to be matched by the right attention to detail in getting them installed properly. Green-tech help us improve the sustainability of our schemes by providing innovative products and techniques to ensure the trees we specify can settle into their new locations quickly and start giving that vital sense of maturity to a scheme that only trees can provide. Correct planting means that they will have the opportunity to survive for many years.

Janine Pattison, Landscape & Garden Design MSGD MBALI

Working to a complete and correct specification can make all the difference to a project when working on site. As a Landscape Contractor, we pride ourselves on the quality of our work and the success of the urban landscapes we work with. Utilising the correct equipment to install a tree or create an open urban space, can make all the difference to our use of time on site, the health and well-being of the plants and trees we care for and most importantly the stamp of approval for the client.

Joe Zazetta, Sustain Landscapes

Ive worked with gtSpecifier in specifying trees for the new ITV headquarters at Salford Quays the project was subject to tight financial constraints and the gtSpecifier team offered us objective and practical guidance on how to achieve what was required in a cost effective way offering technical advice which examined alternative systems and specifications rather than a one size fits all approach

Steve Martlew, Stephen Martlew Landscape Architecture

gtSpecifier has supplied Grace Landscapes with tree planting and landscape maintenance products for over 13 years. Service and delivery is always outstanding and I can rely on the team to go the extra mile when needed.

Hugh Pawsey, Managing Director, Grace Landscapes

Permavoids load-bearing properties prevents compaction, the interaction between the nutrient rich soil mixture in the Permavoid and the percolation of rain through the permeable block pavers provides a slow release feed system to the roots below. When the nutrients are washed through over a long period of time it will leave voids which when encountered by tree roots will air prune their growth to arrest any further upward growth and subsequent damage to the paving above. This system will demonstrate the sustainability & long term cost savings of this approach in terms of tree welfare and eradicating root damage to pavements.

Peter Stringer, Special Projects Manager, Red Rose Forest

As designers and specifiers we very much appreciate the technical support that gtSpecifier have provided, both through their excellent CPD presentations and through their ever helpful telephone technical help. It is reassuring to know that there is up-to-date advice on best practice and innovation in the horticultural industry that is so easily accessible.

Mark Smeedon, Director, Smeedon Foreman Landscape Architects

The Mona product information video represents the standard and clarity to which other product literature can only aspire.

Urban Tree Planting

A Typical Urban Tree

Urban Trees and urban green areas encourage social activities and community cohesion both having a positive physical and psychological effect.Evidence has shown that in some locations areas with high numbers of trees experience less crime.

Tree-lined streets promote calmer driving. Carefully positioned trees can improve sightlines and help to slow down cars. Within urban settings they can be used as an alternative to bollards and speed bumps or to reinforce the presence and enhance the role of a central reservation.

Urban Trees also help to reduce noise pollution, absorbing and deflecting sound.

The presence of vegetation, and soft rather than hard surfaces, reduces the extent to which sound carries around urban areas. Green spaces and Greenroofs reduce noise by reducing reflection of the sound wave and Trees absorbs lateral short wave both elevating urban noise.

Urban Tree Planting

Putting Down Roots - Rootbarrier in Urban Landscapes

Urban trees deliver real economic, social and environmental benefits, but their dense woody root systems grow very close to the surface which can cause considerable damage. The three most common root damages are: Roads, footpaths and cycle

paths can be undermined causing dangerous and damaging surface movement

Structures with shallow foundations can be damaged causing subsidence and cracking

Cabling and pipe work can become compromised

gtRootBarrier offers a solution to this problem, allowing healthy urban root systems to develop to grow but ensuring woody roots are diverted away from vulnerable areas in their search for water and nutrients.

gtSpecifier offers a range of Rootbarriers that can be installed in a number of ways to best suit the required application:

Vertically as a partition between roots and sewage pipes, cables, foundations, roads and pathways

Vertically around trees, shrubs or plants such as bamboo

Wrapped around sewage pipes, cables or mains

Urban Tree Planting

Stability & Protection - Tree & Ground Stabilisation Systems

Most urban tree root systems grow within the top 600mm of the soil in a tree pit.Roots develop and grow in the upper zone of the tree pit because that is where water, minerals and oxygen can be extracted and gained most successfully this process is vital to the trees long term health.

In urban areas the upper zone of the tree pit can experience extreme pressures from hard landscapes, pedestrian and vehicle traffic and water run-off. These pressures can result in the tree pits becoming over-compacted.

The consequence of over-compacted soil is not only poor establishment or failure of the tree but also increase surface water run-off and surface ponding that reduces the visual and physical amenity of the landscape and can contribute to localised flooding.

gtSpecifier has a range of products that provides protection for newly planted trees even in the most challenging urban situations.

gtPermavoid System

Load Bearing Structure

Installing the gtPermavoid system within hard landscaped areas provides a load bearing structure, allowing 70 tonnes per m2 to be traversed over it, making it ideal for areas with heavy trafficking and vehicle access. The structural stability of the gtPermavoid system provides essential protection for the tree pit preventing soil compaction and damage to roots.

Creating A Forest Environment

The units that create the gtPermavoid System can be backfilled with topsoil, providing additional stability for the structure and the newly planted tree. The addition of topsoil at this stage assists with the creation of a forest floor effect providing sustained feeding over a longer period of time, promoting optimum growth and the healthiest possible start for the tree.

Root Control

Optimum root growth spreads from the trunk outwards, close to the soil surface with only 10% of roots choosing their route of growth further than 2m below the ground. Therefore the majority of the trees integral route structure will be close to the soil surface and trunk of the tree.

The gtPermavoid system, sits in a raft position near the top of the tree pit providing an air gap between the hard surface and the trees roots. It is widely recognised that tree roots will only grow in nutrient rich soil and air acts as a natural deterrent for root growth. The air gap created by gtPermavoid encourages root-growth downwards and away from the surface, providing peace of mind for the future of the tree and the urban landscape in which it is planted.

gtPermavoid is a revolutionary, loadbearing tree pit system for the landscape industry that has been tried and tested in Europe for many years.gtPermavoid has been widely used on many high profile urban tree planting projects in the Netherlands over the last ten years.

gtPermavoid is a series of modular units that lock together to form a raft structure. The raft structure is assembled at the nursery line level of the tree to reduce soil compaction whilst at the same time, providing an ideal load-bearing support in hard landscaped areas. The open structure of the gtPermavoid raft system also creates an air void that deters root growth upwards.

Key features:

Creates the perfect growing environment for trees

Simple and quick to install

Directs root growth away from surface

Incorporate with Green-tree top soil for optimal nutrient content, moisture and aeration.

Accommodates a variety of project scenarios

Proven system

Manufactured from recycled materials

Deadman Rootball Fixing SystemPlatimat Rootball Fixing SystemUrban Tree PlantingUrban Tree Planting

Designed to satisfy the requirement of a specialist market, deadman systems offer effective solutions for planting in difficult urban environments where services may be a problem.The systems use kerbstone or sleepers as anchor points and providing that the soil placed on top of the kerbstone or sleepers has been well compacted before placing the tree in the pit, the systems offer fast and efficient method of securing rootball trees up to 12m high.

The preferred method of securing rootballed and containerised semi-mature trees.Platypus platimat has been widely used on many high profile urban tree. The ease of installation and lack of unsightly guy wires makes it the first choice of landscaper architects. The Plati-Mat allows secure positioning of newly transplanted trees, whilst offering major benefits over traditional root support systems.

Available in five standard sizes, the Plati-Mat can be tailored to suit most rootball dimensions. This significant development allows faster installation and provides a greater contact surface area at the top of the rootballed or container grown tree.

Benefits:

Planting at the nursery line

Reduced overall installation time

More secure fixing creating better establishment

No unsightly stakes or timber above ground

Suitable for most rootballed and containerised stock

Urban Tree Planting

D-man Rootball Fixing SystemUrban Tree Planting

An evolution in deadman anchoring. A tree anchor is only as good as the anchor that secures it, with wide ranging variances in sleepers, kerb stone or pin kerbs, loading was not quantifiable and differed from project to project. D-man anchors were created to address this issue. The unique locking cells remove the need for sleepers or kerbs. The cells create a surface area in the base of the tree pit providing a quantifiable anchoring resistance.

Extremely easy to use either individually or in multiples

Removes kerb / sleeper variations from anchor system

Simple to lock/unlock cells together

Cells are omni directional for connecting together

Urban Tree Planting

Thirsty Trees Tree & Plant Irrigation

Newly transplanted urban trees take time to address the balance between the amount of water absorption by the root ball and the loss of water via transpiration.During this initial period of imbalance, additional watering is critical to the survival of newly planted trees. Drought stress remains one of the biggest contributors to high mortality rates of transplanted trees in their first few years of establishment. Research has highlighted that a regular watering regime can result in over three times the growth rate of new roots in an urban tree pit. gtSpecifier offers a specialist range of irrigation solutions that ensures the urban tree receives the very best start.

Mona Plant SystemUrban Tree Planting

An advanced and well proven subterranean irrigation system suitable for interior and exterior planting applications. The Mona Plant System is versatile, cost effective and environmentally friendly, the perfect solution for any landscaping project large or small.The Mona Plant System ensures water and nutrients are delivered in the correct quantity to the roots of plants and trees. This results in healthy root development and optimum growth.

A subterranean system

Manufactured in the UK, all parts are recyclable

No mechanical, electrical or moving parts

Simple to install

Plants roots absorb water from the Mona tanks as and when they require it. (capillary action)

Eliminates over-watering and water wastage

Aerates soil

Reduces watering frequency

Today the Mona Plant System is manufactured and distributed by Green-tech Ltd. It has been specified and installed on many projects across the UK and Europe for over 30 years.

How it worksMona Plant System

The Mona Plant System was developed in Sweden over 30 years ago after extensive research into the growth and success of plants and trees in an urban environment.Naturally a plant takes on essential water and nutrients from the soil, transporting water through its roots. It does this through the process of capillary action, which occurs when the roots absorbing the liquid are stronger than the force of gravity. The water is then pulled through the soil, direct to the plants roots absorbing nutrients from the soil on the way.

Each yellow tank in the Mona Plant System acts as a water reservoir, storing water underground to provide essential water and nutrients as and when required. The yellow reservoirs contain internal capillary legs that can irrigate the roots of plants sitting 150mm above the reservoir and within a 400mm diameter. The Mona Plant System provides a more natural pattern of feeding for the plant resulting in stronger, healthier blooms.

1. Mona tanks are filled with water via a filler pipe above ground

2. Tanks act as reservoirs to hold the water

3. Roots absorb water via the process of capillary action as and when required by the plant

4. A healthy rootball is established and maintained

A Lifetime of Protection - Tree Grilles & GuardsUrban Tree Planting

Urban protection is critical to the survival of a young tree.gtSpecifier tree protection products can also be used to add architectural design and definition to a urbanscape, offering a diverse range of materials and design all manufactured in the UK to ISO9001 Quality Standards.

At ground the trees can be protected using a grille, either in cast iron or fabricated steel. A tree grille allows the tree roots to receive natural water, it prevented the soil in the tree pit being compacted and protects tree root systems from vehicle and pedestrian damage.

Above ground the tree can be protected using a guard. In the earlier stages of a young trees life it is very vulnerable to damage caused by vandalism and traffic this damage can have a detrimental long term effect on the trees development and in worst case can lead to tree mortality.

Cast Iron Tree GrillesCast Iron Tree GrillesUrban Tree PlantingUrban Tree Planting

The Dales Collection

A range of tree grilles that are not only eye-catching and well-designed but will withstand even the busiest of town centres. Designed to protect the tree pit in a pedestrian environment, tree grilles provide essential air and drainage for the trees roots to ensure a healthy and long-life for the planting.

Design & Finish

Manufactured from engineering grade cast iron, the gtDales tree grilles are extremely robust and durable. This is because 250 grade cast iron will not rust in the traditional sense in fact over a 100 year timescale an unpainted gtDales tree grille will only loose a minimal amount of microns to oxidisation. The gtDales tree grilles are built to last. Standard tree grilles are supplied with the natural cast iron finish, alternatively the grilles can be supplied with a painted to match most corporate colours.

Installation

The gtDales grilles are supplied in half or quarter components for ease of transit. Using a Type 1 or Type 2 support frame the grille can be simply bolted within the grille for added stability and security. The Type 2 frame is necessary for specifications that require a tree guard. If additional security is required, security clips are available to prevent unauthorised removal of the tree grille.

Soft Landscaping

Soft Landscaping

For larger urban planting projects that include parks, buffer planting and recreational areas gtSpecifier has developed a number of landscape solutions to accommodate these projects. These urban areas that will experience little or no urban pressures such as heavy trafficking from pedestrians or vehicles will require a different format of planting assistance. This type of urban planting requires a less engineered approach, gtSpecifier offers an extensive range of soft landscaping tree products that will provide optimum growing assistance without the high specification.

More commonly found in rural planting projects the soft landscaping product portfolio offers the tree the protection and support it requires to thrive, but uses more traditional techinques. This creates a softer, rural parkland appearance to the overall planting scheme.

Tree Shelters

Tubex 12D

Tubex 12D is a new material technology combining Biopolymer (starch based) and Oxo-Biodegradable polypropylene. This combination gives customers all the qualities of a TUBEX shelter (flared rim, laserline and twin wall rigidity), whilst ensuring that it degrades in a more controllable fashion.

12D shelters have all the benefits of a traditional shelter (light transmission, microclimate, ventilation, protection, easy to install etc) with the added benefit of better degradation control.

12D shelters offer a complete product lifecycle (shelf life, service life, degradation period) that fits the needs of our customers.

12D biopolymer is made from sustainable resources.

Service Life

The shelters have been designed to suit different applications;

3Y designed to start to degrade after 3 years of service life

5Y designed to start to degrade after 5 years of service life

Degradation time frame

The time frame in which the product degrades will always be dependent on the environment it is in. Many factors contribute to this process, with the important ones being sunlight and whilst bacteria is needed to digest these small chains. It is expected that a 5Y product will offer 5 years of service life, with a further 5 years of degradation.

Dig Deeper with Urban Soils & Growing MediaDig Deeper

The health and structure of a tree is a reflection of the soil health in which it grows.The ecological processes which govern tree survival and growth are concentrated around the soil and root interface. The tree root gains not only water and oxygen from the soil but key essential nutrients - phosphorus, potassium, calcium, magnesium, sulphur and nitrogen.

But the soils in which urban trees grow are often mistreated and of poor quality. The soil is often compacted, have little organic matter or high levels of contaminants. Poor quality tree pit soil results in a poor tree and the benefits they provide are minimised.

gtSpecifier offers a range of manufactured soils that can be both stable and fertile. The benefit of using a manufactured soil is that it can deliver a repeatable quality and can be formulated to site specific needs. This allows the tree to be set in the best foundation possible every time.

Case Study: Holt Park Leisure Centre, LeedsAmenity Tree Soil

Holt Park community leisure centre, located in North Leeds has recently received a multi-million pound overhaul after 36 years of operation.The new leisure centre based on Holtdale Approach transforms the existing building and landscaped areas that had become tired since they first opened in the 1970s.

A main focus of the development was to enhance the existing open space by including soft-landscaped areas within the build, connecting the leisure centre area with surrounding neighbourhoods. The aim is to encourage a pedestrian friendly and an attractive centre for the community to visit.

Green-tree supplied Amenity Tree Soil into this development for the extensive tree planting that surrounds the new leisure centre. Green-tree Amenity Tree Soil is the ideal solution for a development such as this, it provides vital nutrients, water and oxygen that give the trees the best start whilst also preventing soil compaction. The structure and nature of Green-tree Amenity Tree Soil ensures water and oxygen are supplied freely to the trees root system and also aids drainage for tree pits in hard landscaped areas.

David Sowerby for AWS Landscapes commented:

Green-tree Amenity Tree Soil was the ideal solution for this particular project where soft landscaping met with hard landscaped areas. The trees that were imported into the development required a planting medium that would provide a healthy tree pit and stable base for the surrounding hard landscaped area, Green-tree Amenity Tree Soil fulfilled this criteria and has helped us achieve a beautiful landscape for Holt Park.

A load bearing, fertile planting medium designed for use in urban environments.Green-tree Amenity Tree Soil allows the developments of tree root infrastructure under hard surfaces such as pavements and car parking areas. It has a naturally open structure that is load bearing, providing solid structure and aeration to the root system.

Benefits:

Combats problems of poor root structure and subsequent poor growth

Allows compaction whilst providing aeration to soil and allows oxygen and water access to the root system

Compaction testing kits available

Regular testing to maintain quality

Applications:

This product should only be used in situations where a compact soil structure is absolutely unavoidable. In order for the root zone to be successfully implemented, adequate drainage is a must. Green-tree Amenity Tree Soil should be used in conjunction with the Mona Landscape Irrigation range for future irrigation of the urban tree planting.
