SIGMASEAL ( A Crystalline Waterproofing System )
Product Description
It is in powder form which is used in Waterproofing of old and new concrete structures. The product functions by the process of crystallisation.
Concrete is essentially a hard, porous sponge that is subject to cracking at many stages of its life, making it easy for water to seep in through pores, micro cracks and capillary tracts. The water can cause a wide range of problems that damage the concrete or the reinforcing steel. This can dramatically affect the strength, durability and lifespan of concrete.
These products are especially formulated to produce the permeability-reducing crystals or catalyze unreacted concrete components that result in a crystalline lattice that lowers concrete porosity.
It penetrate into the cracks, micro-cracks and capillary tracts of the concrete through osmosis, Brownian movement and dry particle reactions.
Active ingredients react with concrete minerals to form insoluble crystals, which fill out cracks, pores and voids up to a width of 400 microns. This crystalline growth takes place deep inside the concrete structure up to nearly 1 meter from the point of application.
AREA OF USE
It is used effectively for arresting leakages from old and new leaky overhead and underground water tanks.
To waterproof old and new swimming pools.
To waterproof old and new basements.
Bricks as well as on Stone walls .
To waterproof sunken slabs and lift pits.
