Frequently asked questions

  • What is water ingress?

    Water ingress occurs when outside water permeates into a building. Cracks in the surface are common causes of water ingress, roof damage, wall deterioration and defective plumbing.

  • How can I stop water ingress?

    Water leaks are often a result of defective waterproofing which can be repaired by applying a new liquid membrane over the surface as a seamless, flexible and high-strength barrier. When fixing a leak without applying a waterproofing membrane, water ingress can reoccur. 

  • What are common waterproofing issues?

    Structural movement and poor workmanship. An error in workmanship can be simple misjudgements including incorrect choice of membrane for the location or penetrations in the membrane.
