Water Proofing

Frequently building surfaces require the use of waterproofing or damp proofing membranes to protect the building from moisture intrusion. XPS insulation products are applied over the membrane to enhance the performance of both horizontal and vertical applications.

XPS waterproofing insulation products are designed to:

  • improve thermal performance (insulation)
  • prevent condensation on interior surfaces (moisture protection) and
  • enhance drainage (waterproofing protection).
XPS also protects the membrane from backfill damage and traffic loads on horizontal decks.

In horizontal applications, XPS insulation helps extend the waterproofing / damp proofing membrane's life by reducing stress on the membrane caused by temperature cycles.
