Waterproofing Membranes

Waterproofing membranes are commonly used for structural waterproofing solutions as they are continuous, water-tight material built to last.

Waterproofing membranes offer an ideal solution for flat roofs because they are hard wearing, offer a good looking finish and can have a life expectancy of over 50 years.

Types of Waterproofing Membranes

You can get different types of waterproofing membranes to suit different solutions depending on your project and budget.

Below, we have a list of the different types of waterproofing membranes we have available at CARLISLE®.
