Water is a primary agent for both creation and destruction of concrete – and is deeply involved in nearly every form of concrete deterioration. Field experience shows that, in order of decreasing importance, the principal causes for deterioration are the corrosion of reinforced steel, exposure to cycles of freezing and thawing, alkali-silica reaction, and chemical attack. With each of these four causes of concrete deterioration, the permeability and the presence of water are implicated in the mechanisms of expansion and cracking. By ensuring that concrete is waterproof, not just on the surface, but in-depth, we can prevent the main causes of deterioration from happening.
Penetron products are integral waterproofing agents that deliver just that;
- Preventing the corrosion of steel by preventing chemicals from entering the concrete and helping to maintain an alkaline environment
- Preventing damage from freeze-thaw by drying out concrete in-depth
- Preventing alkali-silica reaction by denying the reaction the water it needs
- Preventing chemicals from entering the concrete by sealing the capillaries and pores
Incorporating Penetron products in concrete dramatically increases its durability. In concrete terms, this means the design life of the structure is extended as well as huge savings on repair and maintenance.
