Xypex Concentrate is the most chemically active of the Xypex waterproofing products.
When mixed with water, this light grey powder is applied as a slurry coat to
above-grade or below-grade concrete either as a single coat or as the first of a two-coat application.
It is also mixed in Dry-Pac form for sealing strips at construction joints,
or for the repairing of cracks, faulty construction joints
and honeycombs.
