Recommended Treatment :
Step 1 :
R.C.C. Slab (Sunken slab) : Concrete Slab of RCC (floor and sunken slab) should be prepared incorporating Conproof IWC (an integral waterproofing compound having plasticizing action) to obtain a dense, watertight concrete.
Step 2 :
Two coat of Polyflex WP slurry ( 1: 1.25 WP & cement) on sunken slab Application procedure : Concrete slab after proper curing and cleaning should be treated with cement bound surface sealing compound. Prepare a slurry using 1 part by weight of Polyflex WP and 1¼ part of fresh white or grey ordinary Portland cement. Use a mix by weight 1:1.25 for the first coat and 1:1.5 for subsequent coats. The mixing is best done using a low-speed stirrer, but continuous hand-mixing to a lump-free consistency is also adequate. Damp the surface with sprinkling water before the application of Polyflex WP cement slurry and than apply the slurry by brush to the damp surface. Prepare only as much slurry as can be used within 30 minutes. Keep the mix continuously stirred. Apply by brush two more coats of similar slurry at 24 hour intervals and allow to set for 48 hours. Cure the coating for 3 days by sprinkling water thrice a day on the vertical surface (external walls) and by moist gunny bags on the horizontal surface
Step 3 :
Joint Sealing compound : Seal all the joints such as Nahni – trap joint, P-trap joint, Collar joint, etc., using Joint Sealing Compound over the joints about 10mm thick to provide sufficient lap.
Step 4 :
Waterproof Brick Bed Coba : Infill the sunken portions with waterproof brickbat coba and other filling material. Over the infill waterproofing coba prepare smooth finish screed concrete incorporating Conproof IWC.
Step 5 :
Sealing Tape at the joint between brick bed Coba and Brick wall . Application Procedure : Cut the Colossus Sealing Tape to the required length and press onto the still fresh Colossus sealing compound, which serves as the adhesive base. Ensure that there is a tape overlap of at least 5 cm. Use a smoothing trowel to level out any uneven areas or distortions. Apply two or three coats and ensure that the tape is fully covered with the sealing compound. Use Colossus Moulded Inside Corner and Out Side where ever it require. Colossus Inside Corners / Outside Corner are used as durable, watertight sealing in corners beneath ceramic layers. The inside corners / outside corners are embedded full surface in the sealing Compound used .
Step 6 :
Wall Packing : Colossus Wall Packing is suitable as permanently watertight sealing on wall areas for 1/2″ pipe passages of shower and bathtub water fittings under ceramic coverings. The packing is complete embedded into the Colossus sealing compound..
Step 7 :
Floor Packing : Colossus Floor Packing is watertight, permanently elastic sealing on Nani Trap (Drain). The packing is made from a compound based on polymeric dispersion with a centrally inserted fabric layer. This material basis causes an excellent bonding with almost any waterproofing materials used under tiles extending over the entire surface of the floor packing .
Step 8 :
Tile Adhesive – Tile – Ad (Tile Fixing Premixed) : Fix the tiles with using Tile adhesives.
Step 9 :
Tile Joint Sealing with Tile – Ad (tile Joint Filler ) : Fill the joints between the tiles with waterproof tile joint filler.
