High-strength, eco-friendly, fiber-reinforced, fast-setting repairing geo-mortar, enriched with natural binders and minimun synthetics polymers. It provides:
- Superior strength
- Very good bonding to the substate
- Excellent workability
- Reduced water permeability
- Volume stability
- A very smooth finish. It is not necessary to apply another material in order to achieve a smooth result
- Can be applied in thin (2mm) or thicker layers (40 mm) per coat
- Protection of the reinforcement against corrosion.
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 substrates that could potentially corrode the steel reinforcement. Certified according to EN 1504-3 and classified as a PCC R4 mortar for concrete repairs. 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 evaported or removed with compressed air.
Application
A 25 kg 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.
