Krystol T1 is a surface applied crystalline slurry treatment that transforms new or existing concrete into a permanent waterproofing barrier.

Krystol T1 lowers the permeability of the concrete to protect against the ingress of water and waterborne chemicals. Since it becomes integral to the concrete, it can be applied to either the positive (wet) or negative (dry) side of the water pressure which allows reliable hydrostatic waterproofing protection and remediation for even the most difficult applications.
