MASTERSEAL® 345
MASTERSEAL 345 admixture is a dry-process, sprayable membrane for waterproofing concrete structures. MASTERSEAL 345 admixture is spray-applied in a sandwich between layers of sprayed or cast-in-place concrete. MASTERSEAL 345 admixture exhibits good bond strength to the substrates on both sides of the membrane with good elasticity.
The fully bonded system promotes excellent watertightness characteristics to the underground structure, preventing the development of water migration on both concrete membrane interfaces.
MASTERSEAL 345 admixture cures in 4 to 6 hours (depending on environmental conditions), sufficient to allow a structural concrete lining to be placed, preventing disruption of continued construction operations.
MASTERSEAL 345 admixture can be directly applied to damp sections of substrate.
