Masterseal DR1 Fleece
Masterseal DR 1 admixture is a polypropylene drainage fleece with one
hydrophobe side (hydrophile side with lettering). It is used in
combination with the water-proofing membrane system.

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.
