What is a PVC Sheet Membrane?
PVC Sheet Membrane is a thin layer of water-tight material that is laid over a surface. This layer is continuous and does not allow water to pass through it. For example, on a flat terrace, a waterproofing membrane could be laid above the structural slab and below the finish tiles. This will ensure that water does not seep into the structural slab.
Our waterproofing membrane is strong, flexible, tear-resistant and elastic and stretches to cover cracks and also move with the building. If the membrane is to be exposed to the sun, then we make sure it is UV stable. The membrane is flexible enough to take any shape it is laid over, and be capable of turning up and over walls and other construction features. A blowtorch is used to heat the bottom of the membrane.
Why Sheet Based Waterproof Membranes?
A better seal
The most important requirement of a membrane is that it provides a 100% seal. Even the tiniest gap can completely compromise a wetroom, as water will inevitably find the gap and cause leaks. As the wetroom floor is the area most susceptible to water pooling and leaks, it requires the most robust waterproofing solution.
Sheet membrane has the advantage over liquid membrane of making it very easy to see where the membrane is. When you’re painting a liquid membrane, you can inadvertently create gaps in the seal while sheet membrane can be cut exactly to size.
In addition, sheet membranes have the advantage of a protective backing on both sides that will allow you to keep working in the space even while the membrane is bonding to the substrate. When you’re installing wetrooms on large, commercial projects, productivity is essential. You need everyone working as efficiently as possible. In addition, the backing paper ensures that the membrane remains dust free throughout the installation process.
The problem with liquid membranes is that they can take up to 24 hours to dry depending on the room temperature. During this time, the wetroom space can’t be accessed without compromising the seal. This means that electricians, tilers or other workers can’t carry out their work while the membrane is drying.
Unlike other waterproofing systems, sheet membranes such as our RIW Tilesafe, act as an acoustic barrier, improving the sound impact insulation properties of a wet room by 11db. This is particularly beneficial in properties such as flats and apartment blocks, where the membrane will help reduce sound travelling through to the floors below.
Ready to tile immediately
Thanks to the design of a sheet membrane, the wetroom is ready to tile as soon as the membrane is installed, unlike liquid membranes. This makes it ideal for fast track construction on large projects.
Whether you’re installing onto concrete or timber floors, the thickness of the waterproofing membrane needs to be consistent to ensure it provides a fully waterproof base prior to tiling. Applying a liquid membrane rather than a sheet membrane can often result in an uneven layer and determining the thickness can be time consuming. Sheet membrane has uniform thickness, giving you total peace of mind that applied correctly it will be watertight.
Other Options for Membranes Waterproofing
Liquid Membrane for waterproofing the walls
The walls of a wetroom do not require such a robust waterproofing solution and a liquid membrane such as RIW FWM is ideal. A 1mm liquid coating will provide a waterproof barrier and allow for the walls to be tiled after application. A liquid membrane on the walls also has higher weight bearing properties than a sheet membrane.
