Krystaline Add 1 - Aditivos impermeabilizante para hormigón


Krystaline Add1 uses enhanced hydration to increases the non-soluble amorphous gels and crystals in the concrete. Through a catalytic process, a chemical reaction occurs between the non-hydrated cement particles and water, creating an additional insoluble gels and crystals in the capillary network of the concrete. These deposits become an integral part of the hydrated paste. The resulting concrete has a significantly greater capacity for autogenous crack healing and resistance to water penetration under hydrostatic pressure.

Krystaline Add1 is a state-of-the-art C-S-H technology waterproofing admixture. It has been designed to waterproof and increase the durability of concrete through the use of a unique hydrophilic technology that uses hydration enhancement of the cement paste to provide effective waterproofing, self-healing concrete and corrosion free reinforcing steel.

Krystaline Add1 is an admixture that makes your concrete waterproof, corrosion-free and self-sealing. Krystaline Add 1 is a chemical admixture used for the treatment of concrete structures against water ingress, shrinkage and cracking, chemical attack and corrosion of reinforcing steel.

Krystaline Add1 is a cutting-edge admixture that waterproofs concrete in its entirety. It has been specially designed to waterproof and improve the durability of concrete using hydrophilic crystalline technology.

Concrete is a porous material, with microcracks, voids, pores and capillaries that mainly form in the early stages of setting. The more connected these gaps are, the more permeable the concrete is and the more prone it is to damage caused by the ingress of water and harmful agents. However, Krystaline Add 1 technology practically eliminates concrete porosity and many of its natural weaknesses, thereby increasing its durability.
