Instead of inserting a sheet in between the two layers you paint the liquid membrane directly onto the floor creating an impenetrable moisture barrier.
Damp proof membrane above concrete slab.
Mostly plastic film of vapor retarders is employed below the slab surface as a damp proofing membrane.
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.
Wooden floors to be laid on top of the slab enabling works to be completed more quickly than would otherwise be the case.
Damp proof membrane is used to protect buildings from moisture by creating a damp resistant barrier.
Damp rising through concrete floor slabs is fairly common when a damp proof membrane has failed or was not installed before the floor was laid.
When can a dpm be installed.
The damp proofing of slabs constructed on ground can be done either below or above the surface.
Mostly the damp proofing is installed below the surface of the slab.
Physical damp proof membranes for concrete floors physical damp proof membranes such as oldroyd xs slimline membrane are often quicker and easier to install than using damp proof coatings as they can be installed on still damp surfaces.
It suggests that the damp proof membrane may be above or below the concrete and continuous with the damp proof courses dpc in walls piers and so on.
Epoxy floor coatings concrete sealers.
1200 gauge dpms should be used when a floor is direct to the ground.
If the ground could contain water soluble sulphates or there is any risk that sulphate or other deleterious matter could contaminate the hardcore the membrane should be placed at the base of the concrete slab.
It becomes a problem when the moisture levels are too high and water is transferred to the finishing layer above.
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.
Damp proofing of slabs on ground.
Damp proof membrane dpm an impervious membrane should always be applied as a damp proof membrane dpm above or below a ground floor slab to stop ground moisture reaching the upper surface of the floor.
You should use them to protect all final floor finishes.
