1) WATERPROOFING NORMAL CONCRETE AND BRICK BAT COBA
Clean the surface to remove all loose particles, cracks if any on the surface can be suitably widened. Prime the widened cracks and fill them with Bitu Coat putty. If there are depression and pot holes then prime the depressions with one coat of Bitu Coat and fill and level the depressions and pot holes with Bitu Coat Mortar. Brush apply Bitu Coat on entire surface in two or three coats provide fibre glass of scrim fabric at junctions of vertical and horizontal surfaces.
2} REPAIRING DAMAGED BITUMINOUS FLETS
Cut to widen the cracks and cut out the de-bonded felt. Prime and fill the cracks with Bitu Coat Putty and fill the de-bonded cut out areas with Bitu Coat Mortar. Brush apply Bitu Coat on the entire area in two coats.
3) ASBESTOS/ZINC/ALUMINIUM SHEET ROOFING
Provide scrim or fibre glass fabric at J bolts, and junction of sheet over one coat of Bitu Coat and then brush apply Bitu Coat on the entire surface in two or three coats.
4) CRACKED DRAINING PIPES
Brush apply Bitu Coat on the cracked pipe. When the first Coat is still wet wrap glass/scrim fabric around the pipe and apply second coat of Bitu Coat on the fabric.
5) DAMP PROOF COURSE
On the cleaned plinth apply two coats of Bitu Coats. The second coat applied after about four hours of first coat. When the second coat is still wet blind it with clean sharp sand to provide mechanical key.
6) CONCEALED WATER AND DRAINAGE PIPES
It is a good idea to coat all concealed water and drainage pipes with Bitu Coat to protect concrete from damage due to leakages. Apply one coat of Bitu Coat on the pipe and wrap it with fibre mesh and apply second coat of Bitu Coat and bag fill.
7) SUBSOIL STRUCTURES
Subsoil structures thought main load bearing, in majority of the cases are subjected to water presssure along with chloride and sulfate attack. Hence before bag filling all subsoil structures such as basement walls, footings etc should be coated with two coats of Bitu Coat before bag filling.
8) ANTI TERMITE TREATMENT
Coating of Bitu Coat applied on to the footings and columns upto ground level serves as highly effective anti termite treatment. Most often when conventional anti termite treatments fail, Bitu Coat gives permanent anti termite protections. Two coats of Bitu Coat applied over Bitu Coat Primer serves as very effective anti termite treatment.
