Option 1 install a floor membrane.
Installing damp proof membrane floor.
Fully isolate the dampness from the floor covering.
All types of floor coverings can be installed on top of a plastic membrane.
Our technicians show the best way to apply a damp proof membrane prior to installation of your altro safety or resilient flooring.
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.
This barrier is intended to stop moisture passing from one to the other.
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 becomes a problem when the moisture levels are too high and water is transferred to the finishing layer above.
Two options are available when faced with a damp floor.
This can either be the use of a damp proof coating which is applied on the surface of the concrete or a membrane on top of the concrete.
Preparation will be key to this solution working effectively.

The easiest solution for damp proofing concrete floors is to install a plastic membrane.
Essentially this is a plastic mesh sheet specially formulated to ensure that moisture cannot penetrate.
A damp proof membrane dpm is used to create a barrier between a concrete or screed subfloor and the floor covering that is laid on top such as wood ceramic or quartz tiles laminate or carpet.
It sits between the concrete and the underlay floor covering.
Damp proof floor coating.
They can be used on walls after the installation of a new dpc or to provide a key or as a dpm with a concrete slab.
They do however always require a separate floor covering on top and special attention needs to be paid to the floor wall junction detail.
A damp proof coating will be applied onto the concrete floor with a roller or brush.
The damp proof membranes used during construction of concrete floors are often thin and can easily become torn before they are laid rendering them.
