We hold immense expertise in our domain that helps us to systematically execute our Basement Waterproofing services. These services are demanded across the nation owing to their cost-effectiveness, timely execution and reliability. Superior-grade coating and other materials are used for waterproofing of the surfaces of basement so as to make these highly crack and water resistant. While executing our Basement Waterproofing services, we pay optimum attention to the guidelines given by our clients so as to gain their optimum satisfaction.
Local treatments (Point Leak and Construction Joint)
Arresting water leakages at isolated locations (point leakage) and at construction joints with a putty of cement (OPC or slag), modified with a cementitious quick setting compound (bulk density 0.80 to 0.85 gm/cc and a pH of 7.5 8.0 for a 20% aqueous solution at 350C), e.g., PERMAKAR 4, in a weight ratio of 1:10 (1 part of the compound and 10 parts of cement), further modified with a silica waterproofing compound (density not less than 1.53 and a pH of 10.0 10.5 for a 5% aqueous solution at 350C), e.g., PERMAKAR 1 having the properties of making cement quick setting and non-shrinking in quantities to suit the water pressure conditions at the site
Requirement : 0.40 kg/each Point Leak and 1.20kg/metre of Construction joint for tunnels, basements, water reservoirs and other water retaining structures
PERMAKAR 4 :
Requirement : 0.095 kg/each Point leak and 0.32 kg/metre of Construction joint for tunnels, basements, water reservoirs and other water retaining structures
Cleaning the surface; preparing the surface by acid etching; treating the surface with a two layer plaster; the first layer shall be 7 mm thick in case of inside walls and floors of water reservoirs and swimming pools, 6 mm thick for sunken slabs/toilet floors and inside of tunnels, basements, etc. with octadecanoic acid based cementitious waterproofing compound (bulk density not greater than 0.5 gm/cc, moisture content not greater than 2.0% and a free fatty acid not greater than 0.2%), e.g., PERMAKAR 3, and cement in the weight ratio of 3:50 for waterproofing compound and cement; cement-sand (1:2 on floors of basements and tunnels; 1:3 elsewhere) plaster (12 mm thick on floor; 8 mm thick on vertical surfaces and at ceiling) and curing the plastered surface; the treatment shall be impermeable under a waterhead of 20.0 metres.
Requirement : 0.72 kg/sqm for inside of tunnels, basements and toilets and 0.84 kg/sqm for water reservoirs and other water retaining structures where treatment will be in direct contact with water
