Megaflex: fibre-reinforced cementitious waterproofing for concrete structures
Big5 Megaflex is a cementitious waterproofing slurry that protects concrete structures against water and hydrostatic pressure. It suits concrete tanks, basements, bridges, balconies, showers and under-tile areas, forming a durable, fibre-reinforced moisture barrier that is easy to apply. As an elastomeric, fibre-reinforced coating it gives long-lasting protection against the elements.
Key Benefits
- Handles hydrostatic pressure. Made for tanks, basements and below-ground concrete.
- Fibre-reinforced. Elastomeric film with added tensile strength.
- Under-tile and wet areas. Balconies, showers and bathrooms.
- Durable moisture barrier. Long-lasting protection on concrete.
- Easy to apply. Brush or trowel-applied slurry.
Technical Overview
Megaflex is a cementitious, elastomeric waterproofing slurry reinforced with fibre. Mixed and applied to concrete, it bonds into the surface and cures to a tough, flexible barrier that resists positive and negative water pressure, which is why it suits water-retaining and below-ground structures. The fibre reinforcement adds crack resistance, and the coating can be tiled over in wet areas.

Technical Guidance
Prepare a clean, sound concrete surface and dampen it before applying. Mix the slurry to a workable consistency and apply the recommended number of coats, working it well into the surface. Allow proper curing before filling tanks or tiling over. For wet rooms, extend the coating up the walls at junctions.
SPREADING RATE
SPREADING RATE
At a consumption rate of 1,5 to 2,5kg per m² the yield per 15kg kit will be between 6 to 10m²

Questions & Answers
Have a Question?
-
What is cementitious waterproofing?
Cementitious waterproofing is a cement-based slurry, like Megaflex, that bonds into concrete and resists water pressure. It is ideal for tanks, basements and wet areas.
-
How much does a unit cover?
A 15kg unit covers about 6-10 m² per coat.
-
Can it be used in showers and under tiles?
Yes, it suits balconies, showers and under-tile wet areas.
-
Is it fibre reinforced?
Yes, it is an elastomeric coating reinforced with fibre for added strength.
-
Is Megaflex suitable for basements?
Yes, it is a moisture barrier for basements and foundation walls against water pressure.
-
How do I waterproof a concrete dam or tank?
Use a cementitious system like Megaflex, engineered for hydrostatic pressure on water-retaining concrete.
