Portland cement concrete is widely used in the world's construction due to its durability. However, it comes with limitations; concrete is a porous material and its level of compactness depends on the water/cement ratio employed to prepare the mix. The porosity within its structure provides an access route for moisture and for dissolved pollutants contained in the moisture.
The main reasons concrete deteriorates is due to the presence of water in the following forms:
Aggression by sulphates
Aggression by chlorides
The Planiseal WR 100 is one of the many Mapei products that can prevent the main causes of concrete deterioration. It is a ready-mixed pure silane-based, hydrophobising, protective, migrating liquid applied to the surface of reinforced concrete structures exposed to aggressive agents.
Planiseal WR 100 travels through the capillary pores and penetrates deep down into concrete to form a protective, hydrophobic coating that, over the years, helps to prevent the degradation and detachment of concrete. It drastically reduces water and chloride absorption and helps to prevent corrosion of the reinforcement steel in concrete. It also helps to prevent deterioration of new and repaired concrete caused by freeze-thaw cycles and de-icing salts and increases its durability.
High penetration capacity
Drastically reduce absorption of water and chlorides
Applied directly on the surface of the concrete to be treated
Prevent corrosion of steel reinforcement
Increase durability of both new and repaired structures
Complies with EU norms: EN 1504-9 and EN 1504-2
It can be applied directly on both vertical and horizontal surfaces of porous and compact concrete, on new concrete and on concrete that has already been repaired or with no evident signs of detachment from the reinforcing steel. Application: by low pressure airless spray on large surfaces or with a roller for smaller areas.
Piles and abutments on bridges and viaducts
Structures in marine environments such as jetties, quaysides, etc
Prefabricated reinforced concrete structures
Front edges of balconies
Prefabricated structures such as buffer panels, beams, columns, etc
Internal and external reinforced concrete structures in general
