Liquid-Applied Waterproofing Membrane
Liquid-applied membrane is a flexible waterproofing system that forms a seamless protective layer over the treated surface.
Because we apply the membrane in liquid form, it can follow irregular shapes, corners, joints and complex details more easily than many sheet-based systems. Once cured, it creates a continuous waterproof barrier without overlapping sheet joints.
Its flexibility also allows the membrane to accommodate minor cracks and surface movement. As a result, it is particularly suitable for balconies, car porches, external walls and roof areas with complex detailing.
What is Liquid Membrane
Liquid-applied membrane is a waterproofing system that we apply directly onto a properly prepared surface.
Once cured, the liquid material forms a flexible and continuous membrane that helps prevent water penetration.
Unlike sheet membranes, the system can adapt closely to corners, joints, penetrations and irregular surfaces. Therefore, it works particularly well in areas where complex detailing makes sheet installation more difficult.
Its flexible properties also help the membrane accommodate minor movement and small surface cracks.
Key Benefits of Liquid-Applied Membrane
Forms a seamless waterproofing layer without joints
Reinforced to improve durability and reduce the risk of tearing
Adheres well to prepared concrete and masonry surfaces
Flexible enough to accommodate minor cracks and surface movement
Suitable for areas exposed to weather and regular water contact
Helps maintain waterproofing performance even as surfaces expand and contract
Liquid-Applied Membrane Application Method
-
Prepare the surface
First, our team inspects the surface for dirt, loose materials, cracks and other defects that may affect the waterproofing system. We then clean and prepare the area to create a sound, dry and stable base for the membrane. -
First Layer: Primer Application
Next, we apply a compatible primer where required. The primer improves adhesion between the prepared substrate and the liquid membrane system, helping the waterproofing layer bond more securely to the surface.
Once the primer is ready, we proceed with the first membrane coat. -
Second Layer: First Membrane Layer
We then apply the liquid membrane evenly across the prepared surface. Our team pays particular attention to corners, joints, edges and penetrations to ensure consistent coverage across critical areas.
This first coat forms the initial waterproofing layer. -
Third Layer: Fibre Reinforcement (As Required)
Where additional strength is required, we embed fibre reinforcement into the wet membrane. The reinforcement helps strengthen critical areas and reduces the risk of tearing or separation around joints, corners and other vulnerable sections. -
Fourth Layer: Second Membrane Layer
Once the first coat is ready, we apply another layer of liquid membrane across the treated surface. This coat covers the reinforcement and helps build up the waterproofing system to achieve more consistent protection. -
Fifth Layer: Final Membrane Layer
Finally, we apply the last membrane coat to complete the system. Once fully cured, the layers form a continuous and flexible waterproof barrier over the treated surface.
