The Henry Bakor Aqua-Bloc 720-38 18.9-Litre Elastomeric Asphalt Emulsion Waterproof Membrane is an elastomeric, liquid-applied, emulsified asphalt membrane. It is designed for below grade waterproofing of foundation walls and other structures. Aqua-Bloc 720-38 complies with, and exceeds, the requirements of CAN/CGSB 37.2.
Features
- Water-based and VOC Compliant
- Seamless low modulus elastomeric membrane
- Excellent adhesion to most construction surfaces such as concrete, stone, wood, preserved wood, metal and polystyrene
- Retains flexibility over a wide temperature range
- Perfect for waterproofing ICF (Insulated Concrete Forms) foundation walls
- Can be applied to damp or green concrete
- Can be applied in one coat or in multiple coats with reinforcing fabric
- Bridges cracks
- Environmentally friendly due to no solvent content
