Externally-applied Below-ground Wall Waterproofing
External waterproofing of below-ground walls is recommended for basements. The use of drainage ditches is recommended in order to remove rainwater from the home.
- Resistance to water pressure
- Single-component waterproofing
- Flexible system
- Easy application: by roller, brush or trowel
- Covers cracks up to 0.75 mm
- High adhesion to substrate
For this type of drainage system, waterproofing the exterior face of below-ground walls requires an efficient solution that is resistant to water pressure.
Consequently, SECILTEK offers the cement-based single-component mortar Hidrostop FLEX, which resists water pressure and ensures the proper water tightness of underground walls.
