Why Choose Xypex Megamix II?

Concrete can deteriorate over time due to water penetration, environmental exposure and general wear. Effective repairs need to restore damaged areas while also helping protect the concrete from further moisture ingress.

Xypex Megamix II combines concrete repair and crystalline waterproofing technology in one product. Its polymer-fibre-reinforced formulation makes it suitable for rebuilding damaged concrete, while its crystalline technology provides additional protection against water penetration.

The ability to apply the mortar at varying thicknesses and by either trowel or spray makes Megamix II a versatile choice for contractors undertaking concrete repair, remediation and waterproofing projects.
