Catalyst PWC

Crommelin Catalyst PWC is a biochemical modified silicate solution that provides long-term waterproofing and durability benefits to concrete.

Catalyst PWC penetrates into concrete and reacts with free calcium and water to form a water insoluble calcium silicate hydrate gel complex in cracks, pores and capillaries, creating a sub-surface barrier against water and chloride ions.

• 100% trafficable after the first watering.
• Permanently seals existing cracks to 0.8mm.
• Re-seals future hairline cracking.
• UV stable – will not peel or yellow.
• Increases surface hardness.
• Allows moisture vapour permeability.
• Suitability for tanking applications. (Positive hydrostatic pressure)
