Sika answers permeability with hydrophobic hydrophilic admixtures

The introduction of a powdered, concrete plant-dispensed agent positions Sika Corp. as reportedly the only admixture producer to offer the two core permeability reducing technologies: hydrophilic crystalline and hydrophobic pore blocking.

Its moisture activated compounds produce insoluble crystalline deposits that form within the capillary system. The crystalline formulations have the ability to reduce capillary pore size and prevent water penetration in concrete slabs or structures.
