Insulating Concrete Forms???Decorative Concrete??Pervious Concrete?

• Raw polystyrene beads are molded into one of two basic forms.

• Block systems simply stack and interlock-almost like big Lego’s.

• Panel systems are held a constant distance apart by a series of plastic ties.

Today there are more

than 70 manufacturers of Insulating Concrete Forms. Buyer Beware!!!

Solid Value & ComfortThe Stabilizing Effect of Thermal

Mass

Frank Lloyd Wright – • “My buildings will last at least 300 years!” • Began using concrete as early as 1889.• Concrete is “so flexible and simple as to be almost

unbelievable.”

CONCRETE HISTORY

CONCRETE HISTORY

Thomas Edison – • Believed that “concrete was the material that would

revolutionize housing”. • Felt concrete would build cost effective homes. • In 1908, he built 11 homes similar to this model.

Peace and QuietAn ICF structure is peaceful and quiet, reducing sound penetration by over 80% when compared to wood structures.

Savings

Better resale value According to a 1998 Appraisal Journal article,

energy efficiency improves resale value The study found that for every $1 reduction in

annual fuel bills, the resale value of a home is increased by $10 to $25

Example: If your savings were $400 per year, then your home would sell for $4,000 to $10,000 more than a conventionally built home

“Traditional” Frame Insulation

– 20% wood (R - 4.38)– 80% insulation (R -11)

– Total R - < 11– Thermal Breaks– Air Infiltration

ICF Insulation

• Continuous insulation (avg R - 20)

• Monolithic Concrete

• True R Value• Airtight Construction• Attachment Strips

A wood framed wall would

have to be insulated to a

level exceeding R50 in

many cases, in order to

perform at a level

equivalent to an ICF

wall.

Savings Summary:

• Insurance discounts as high as 25%.on-going savings for the life of the home.

• Energy consumption savings of 44% for heating, and 32% for cooling. This can add up to huge lifetime savings!

• Labor hours are drastically reduced.The material is extremely lightweight, requiring less effort to lift, move, place or cut. Eliminates other building steps.

Single Family Residential Summary:

• Home Buyers have Wants and Objectives• With ICF, Builders can satisfy Buyers

Wants.• ICF Homes EXCEED Expectations and

can translate to higher profits for builders and savings for the owners.

Commercial/Multifamily Residential

• Energy Savings• Fire Ratings• Structural Envelope• Building Flexibility• Code Approvals• Compatibility with Commercial Designs• Speed

Demand for durability and energy performance is growing. ICF technology is a proven building system.

When compared with other building materials, concrete is a responsible, wise choice for sustainable development.

Pervious Concrete

SS Credit 6: Stormwater Design• Design project site to

maintain natural stormwater flows– Whole site considered for

credit• Pervious/permeable

concretes are one part of solution

• Also landscaping, existing native vegitation etc.

Hard pavement collects runoff and sends it downstream.

Concentrated Runoff is created.

Pervious pavement keeps rainfall on site by Infiltration & Dispersion

No Runoff is created.

Pervious Concrete createsA Micro-ecosystem

Water-held by capillary tension

Designing & Specifying A Pervious Concrete Pavement Structure

• ACI 5221-08• Define loading condition• Assess soil support value• Select thickness based on flexural

strength (MR=375 psi) • Check against overweight loading

– ½” thickness increase can increase strength and life expectancy by 33% to 50%

Storage CapacityStorage capacity typically governs designDepends on porosity of pervious pavement and

subbase1” of pavement with 15% porosity can store

0.15”1” of #67 stone base with 40% porosity can

store 0.40”4” pavement on 6” subbase can store 3” of rainPorosity depends on level of compactionPre-construction test to establish porosity vs.

unit weight

NRMCA Qualified Contractors:

• They have the right equipment • They understand this concrete is a

stormwater management tool• Trained & Certified Contractors know

how to get the correct results with “no-fines” materials.

Damp Proofing

By Jillian Todd

Do You Think You Might Have Water Issues?

Do You Know You’ll Have Water Issues?

What To Do?

• Assess the expected severity of the problem.

• Work with your concrete supplier in ideas on mitigating the problem.

Idea #1 On Mitigating The Problem

Upgrade the concrete mix design

– Add Air Entrainment – Add Fly Ash– Add a water reducing admixture or high range

water reducer– Use a low water/ cement ratio concrete mix– Add fibers

80

Idea #2 On Mitigating The Problem

Stego Wrap Vapor Barrier / Retarder

10 or 15 mill welded barrier - Stego

81

Stego

• Under Slab placement

• Vertical Wall placement

Idea #3 On Mitigating The Problem

• Upgrade the concrete mix design w/ more advanced admixtures.

– Add RHEO Mix 235– Around $8.00 per yard

Guidelines For Getting The Best Service From Your

Concrete Supplier

Work with your local supplier

Know what you need:• Are there specifications?• Do you need admixtures?• How do you need the concrete to perform?

Ordering Concrete

• Call dispatch department

• Have all information ready

Order Cards

• Account name & Contact info.• Complete address• 2” slump!! Fairly Dry• No pumping necessary• Clean up load of 3 yards will finish my

job with a little left in the truck.

• Time slot

Scheduling

• 1st Round Firm orders• Will call order reasoning:Weather Pending?

Inspection Pending?

Pump Hold?

Order Quantity

• Exact yardage: (Supplier will follow & plan accordingly)

• Plus Order: 18+ 3 trucks• Add on Order: 50+ not over 70 yds.

Additional Service Fees

• Minimum load• Minimum color load• Unload time: avg. 10 min per yd.• $10.00/min exceeding• Truck wait charges possible
