• All underground concrete structures or wet/damp areas.

• a. Packaging: 1.0 m x 20 m/roll
• b. Thickness: 1.5 mm

a. Substrate preparation:

• The concrete surface must be clean, free of dirt and sharp objects.
• Surface of lean concrete must be flat, solid without gaps greater than 10 mm.
• Concrete must be sound without honeycomb or any defects.
• Construction joints must be flat. It should be reinforced following suggestion from waterproofing supplier.
• Substrate can be damp but without standing water.
• Standing water must be cleaned by compressed air prior to application of the waterproofing membrane.

b. Membrane application:

• The concrete substrate must be made saturated with water.
• All gaps must be filled with cement mortar or using suitable methods.
• Mix cement PCB40 with water by forced mixer until it becomes a homogeneous slurry.
• Pre-determine the volume of cement, mix cement and water following ratio Water : Cement = 0.4 (by weight). Bulk cement or bagging cement can be used.
• Mixing time is 3 – 5 minutes. Mix until a homogeneous slurry.
• If the slurry starts to set, it can be remixed and used. Adding water is not acceptable.
• Use mixed slurry within 45 minutes.
• Use trowel to plaster slurry on concrete surface. The thickness of cement slurry is about 2 mm.
• Manually apply waterproofing membranes. Spread membranes on cement slurry when it’s still wet.
• Waterproofing membranes are joined by self-adhesive splice. Splice is 80 mm in both length and width.
• Use steel rollers to firmly seal the membranes together.
