Terrace Solution
Removal of brickbat coba / plastic / waterproofing membrane, if any upto
mother slab
Concrete Substrate
Step 1
Waterproofing done on existing plasters/brick bat/bitumenousmembrane will not give a fool-proof solution as water may penetrate through cracks developed in these systems. Hence, sound concrete substrate needs to be exposed before any treatment.

Step 4
Usage Guidelines
Clean the surface of any dust, dirt,
laitance, etc. and bring substrate to Saturated Surface
Dry (SSD) condition
Step 5
Proper surface preparation through chemical/ mechanical cleaning, blast or acid etching is extremely important for an effective performance of waterproofing system. Creating a dry, level and silt/dust/ laitance free surface allows stronger bond/adhesion between the waterproof system and substrate.
Saturated surface dry condition prevents rapid drying and weakening of waterproofing coatings and its bond to the substrate.

Step 11
Ponding with water serves a dual purpose. As waterproofing system is cementitious based, water helps in hydration of unreactedcement particles developing mechanical strength and also helps in ascertaining whether any water is leaking.

Permeability of concrete is greatly improved. With increased cohesion, segregation and bleeding
are substantially reduced. Is highly effective in reduction of permeability due
to hydrostatic head pressure or capillary action or both.
Increased retention property of slump. Improved surface finish of concrete. Very high quality – indigenous polymer blend.
