High-strength, eco-friendly, fiber-reinforced, fast-setting repairing geo-mortar, enriched with natural binders and minimum synthetics polymers. MEGACRET-40 GEO contains special additives that are able to penetrate deep into concrete and form a protective layer on the surface of the steel reinforcement. Moreover, they reduce the porosity of concrete and thus increase its water impermeability, preventing the penetration of substances that could potentially corrode the steel reinforcement. Certified according to EN 1504-3 and classified as a PCC R4 mortar for concrete repairs. Certified according to EN 1504-7 and classified as a product for reinforcement corrosion protection. CE marked.

MEGACRET-40 GEO is suitable for highly demanding repairs in concrete element. It is applied with a trowel or pneumatically with a gunite process to floors, walls or ceilings.

Substrate preparation

The substrate must be free of dust, grease or any foreign material. Before applying MEGACRET-40 GEO, the substrate has to be thoroughly dampened and then the excess of water should either be evaporated or removed with compressed air.

Application

A 25kg bag of MEGACRET-40 GEO is gradually added to 4.80-5.00 l of water under continuous stirring, until a homogenous, tight mass is formed, appropriate for repair works. Either a low speed mixer or a concrete mixer could be used for the mixing. The material should be applied (pressed) to the desired thickness-up to 4 cm per layer – with a trowel or pneumatically with a gunite process. When a second layer is required, the surface of the first layer should be roughened, to achieve better adhesion. The final surface should be well protected from dehydration by being covered with wet cloths or polyethylene sheets, or repeatedly dampened for 48 hours.
