TERRACEWATERPROOFING

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/bitumenous membrane 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

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 10

Ponding test:Pond floor with

water for 72 hours to allow

curing and check for any leakage

Step 11

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