GCP offers a range of SILCOR® liquid waterproofing products including SILCOR® 900 series, with polyuria technology for buried roofs and decks

SILCOR® 900 liquid waterproofing is a durable, easy-to-apply waterproofing solution that cures quickly. It’s easier to apply than hot, liquid-applied membranes or torched on waterproofing, saving you time and hassle.



SILCOR® 900 liquid waterproofing simplifies waterproofing application. Simply spray or paint the liquid membrane waterproofing solution onto the prepared and primed substrate. The liquid waterproofing cures to form one solid, 100% monolithic membrane. For larger projects, this can often cut days off the installation time.

Simplify Application

Sprayable or hand painted seamless single layer application is fast to apply, simplifies details, cures quickly and is rain resistant, giving you greater flexibility in your project schedule.

Minimize Safety Risks

SILCOR® liquid waterproofing reduces the site risks inherent with alternative waterproofing applications that require flame.

Proven High Performance

Forms a durable and resilient high performing waterproofing membrane that is fully bonded to the substrate, keeping water from tracking beneath the membrane.
