Radmyx Capillary Waterproofing System



Radmyx Capillary Waterproofing System is a complete “once-and-for-all” approach to waterproofing below grade concrete structures such as basements, tunnels, culverts and water holding vessels.

Radmyx can be used as an admixture, slurry coat, sprinkle or mortar and is effective against positive or negative water pressure.

Radmyx reats with the hydration products of cement to form crystals within the cracks, pores and capillaries of concrete structures – thereby effectively blocking the passage of water. Complete waterproofing is normally achieved within 5-7 days from application. After the crystallisation process has successfully waterproofed the structure the active chemicals in Radmyx remain dormant in the concrete. Any subsequent contact with water will reactivate the Radmyx sealing process.
