This video showcases Dura Build Care’s use of poly-grout technology to seal cracks and pores in concrete structures to effectively waterproof them. First of all, DURAGEL which is a water reactive poly-grout is taken in a testing container,   and then water is added to test the efficiency of DURAGEL.

As you can see the reaction starts and it start swelling up, in real life application this can be used to seal pores & cracks which are present inside the concrete.

As the reaction starts the contents begin to swell. Generally its swells to around 8 to 10 times of the amount of Duragel liquid that has been taken.

We let the reaction complete at its own pace, which is very quick as you can see it. As it settles it becomes more rubberized. When  pressed, it is no longer compressible. It has now solidified, which means that the cracks in pores are sealed now.

Other methods  used to seal contrete cracks include:

Integral water proofing is a method that keeps water out of the concrete due to capillary action or hydrostatic head, forming a crystal which blocks the pores.

Polymer modified bituminous coating is a method that makes use of bitumen, which moves with the concrete and doesn’t allow the water to concentrate inside the structure.

Silicone water proofing is rain coating applied on the outer walls of the concrete, making it water repelling.

Crystalline water proof system is a system that uses advanced ranges of crystalline water proofs to reduce the pore size by forming non-soluble crystals within the concrete microstructure.

Cementitious Polymer Coating is coating used to treat the mother concrete substrate making sure that the use of any foreign materials is avoided due to its cement related properties.
