In these situations it is better to use a cavity drainage system to manage any water ingress rather than a dpm.
Damp proof membrane concrete slab.
In newbuild situations it may be necessary to install a damp proof membrane on top of a concrete slab to enable moisture sensitive floor finishes e g.
Mostly plastic film of vapor retarders is employed below the slab surface as a damp proofing membrane.
Most damp proof floor coatings are applied directly to the concrete floor surface using a brush or roller.
Damp proof membrane is used to protect buildings from moisture by creating a damp resistant barrier.
Underfloor heating pipes are put in place if necessary.
A dpm damp proof membrane is a plastic sheet membrane that sits between a concrete slab or screed and acts as a barrier to stop moisture and contaminants entering a property from the ground.
Preparation is key with these coatings and the substrate must be sufficiently clean and dry.
Commonly used to protect a buildings concrete slab from moisture rising from the foundations damp proof membrane is a versatile product and can be used for a wide range of applications such as creating a protective surface before laying laminate or wood floors.
Which type of coating is chosen will depend on the intended use of the floor.
A damp proof membrane is put down.
When can a dpm be installed.
Damp proofing of slabs on ground.
All types of floor coverings can be installed on top of a plastic membrane.
The easiest solution for damp proofing concrete floors is to install a plastic membrane.
Typically a dpm is a polyethylene sheet laid under a concrete slab to prevent the concrete from gaining moisture through capillary action.
It sits between the concrete and the underlay floor covering.
Damp proof membrane under concrete slab as the majority of basements and cellars are fully below ground they are prone to water ingress.
Insulation is put down.
In essence providing a moisture barrier or damp proof membrane for concrete slabs.
Mostly the damp proofing is installed below the surface of the slab.
1200 gauge dpms should be used when a floor is direct to the ground.
Essentially this is a plastic mesh sheet specially formulated to ensure that moisture cannot penetrate.
The damp proofing of slabs constructed on ground can be done either below or above the surface.
Can also be used as a drop sheet or for temporary weather protection when required.
You should use them to protect all final floor finishes.
Concrete is poured and left to cure for a minimum of three days.
