A CRYSTALLINE INTEGRAL WATERPROOFING SYSTEM FOR CONCRETE AND MORTARS
Perma Seal Admix is used effectively as an integral waterproofing compound in
concrete during construction of all water retaining structures, underground and overhead water tanks, swimming pools, water treatment plants, basements, podium slabs, roof slabs and all RCC members around toilets and bathrooms in a building structure. It is also used as integral waterproofing compound in mortars which go as renderings on all these structures. Since leakages corrode the reinforcing steel in RCC structures thereby reducing the life of structure itself, it is a good to use a good integral waterproofing compound in all concrete produced for use in RCC
Perma Seal Admix is composed of Ordinary Portland Cement selected and treated fillers and proprietary active chemicals. In contact with moisture these active chemicals catalyze the reaction of products of cement hydration to form insoluble micro-fine crystals which effectively block the capillary structures in the concrete body blocking the passage of water. Thus the concrete becomes permanently sealed against any penetrating water or liquids.
DIRECTIONS FOR USE
Perma Seal Admix is recommended at a dosage of 2% by weight of cement. Perma Seal Admix is added to the dry mix of concrete or mortar at the recommended dosage and mixed before addition of designed amount of water. Perma Seal Admix does not alter the water requirement of the concrete. Mixing, placing, compacting and curing of concrete is expected to go as per usual practice and no special care or requirement is needed because of Perma Seal Admix addition to the concrete mix.
GOOD CONCRETING PRACTICE
For achieving good quality waterproof concrete the following guidelines are recommended:
Concreting when ambient temperatures are over 33oC or below 4oC is not recommended.
Minimum cement content in concrete for achieving good waterproof quality is 300Kgs/ M3 .
Pouring of the concrete after its initial or final setting time of the concrete has lapsed is not recommended.
For a waterproof concrete water/cement ratio should be maintained at 0.43 or leff depending upon grade of concrete.
Control joints in big structures need to be incorporated as per the requirement and the design of a competent structural engineer. Any deformations, cracks and structural failures arising out of want of control joint design will nullify all waterproofing treatments and create more problems
Perma Seal Admix is recommended to be added to the dry concrete mix at a dosage of 2% by weight of cement
Perma Seal Admix is available in 10 kg & 25 Kg bags.
Perma Seal Admix has a shelf life of 12 months from the date of manufacture..
