The performance of concrete as a construction material depends on a number of factors; its original quality,
exposure conditions, design and the standard to which it has been applied, all have a bearing on its durability.
All concrete will be subject to chemical and physical change. However one of the main causes of concrete failure is
due to reinforcement corrosion. The following CE labelled materials can be used for repairs to improve the alkalinity of
the damaged areas;
Principle Causes The principle factors involved in
reinforcement corrosion are
carbonation and chloride attack. Other
factors such as alki-silica reaction,
chemical attack, impact damage and frost
action may also prove important.
Carbonation Most commonly the loss of alkalinity in
concrete occurs through carbonation,
where carbon dioxide reacts with the
alkaline materials in the concrete
converting them to carbonates. This
causes the pH to fall below the level
required for passivation resulting in
reinforcement corrosion.
Chloride Attack Chlorides may be present in concrete
from the time it was originally mixed
or they may migrate in by de-icing or
marine salts. Combined with the
presence of moisture they will cause
rapid deterioration of the
reinforcement.
It is essential that the reasons for and
the extent of the problem is identified
before carrying out any repairs.
Protective Coatings
Nucem Skim Coat A blend of high grade cements, fine aggregates and acrylic resin designed to produce a
flexible levelling coat to cover areas repaired and existing concrete. Nucem Skim Coat gives
an overall uniform appearance or a consistent surface to receive protective coatings. Polymer
modified, capable of bridging hairline cracks and ideal for treating areas with low
reinforcement cover. Tested by Taywood.
Proflex ‘A’ Flexible, anti-carbonation coating. A high build acrylic emulsion designed to protect concrete
from the ingress of rain water and air-borne pollutants, while allowing substrates to breathe.
Also suitable for protection and decoration of a wide range of wall and sheet roofing
materials. Tested by Taywood.
Covercrete Highly durable weather-resistant anti-carbonation coating. This water-based acrylic emulsion
is deigned to significantly reduce the diffusion rate of Carbon Dioxide and protect from
chloride attack. Available in a range of decorative colours. Tested by Taywood.
Nucryl
An effective clear anti-carbonation coating. Solvent borne Acrylic treatment with excellent
resistance properties that provides a long-lasting barrier to protect against Carbon Dioxide,
for the protection of substrates from aggressive atmospheric contaminants.
Repair Mortars
Nucem Primer A cementitious epoxy blend, with long tack free time, designed to promote extremely high bond
strengths. Recognised as one of the best available, the epoxy primer system can be used in wet or dry
conditions. In addition, Nucem Primer protects reinforcement against further corrosion even under the
most adverse conditions.
Nucem HB Mortar/Acropak HB40 Mortar Polymer modified, shrinkage compensated, fibre reinforced, cementitious mortars with high build
characteristics for vertical and inverted surfaces without the need for shuttering. Polymers reduce
damage from CO₂ , ingress of water, chlorides and certain sulphates. Nylon fibres reduce shrinkage
cracking, make the mortar easier to apply and greatly increases the flexural strength of the system.
Complies with BD27/86 Clause 6.
Nucem Concrete/ Nucem Mortar Prepacked polymer modified systems which contain specially graded aggregates for high strength and
abrasion resistance on decks. Excellent resistance to water, frost and salt permeability enabling these
products to be used for heavy duty repairs under the most adverse conditions.
Suitable for next day waterproofing. Complies with BD27/86 Clause 6.
Deck Repair Rapid Deck Repair Rapid is charactersised but its early high strength development, rapid moisture loss and
shrinkage compensation. Designed for quick, easy installation and suitable for next day waterproofing
of bridge decks and areas where rapid turnaround is important. Complies with BD27/86 Clause 6.
