Damp Proof Membrane In Concrete Floor

A liquid epoxy damp proof membrane dpm is often used as a remedial solution where an existing dpm has failed or was never installed. 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. Typically a dpm is a polyethylene sheet laid under a concrete slab to prevent the concrete from gaining moisture through capillary action.

Damp proof membranes for concrete i know we re repeating ourselves but a damp proof membraneis one of the most fundamental methods of sealing a damp floor.

Damp proof membrane in concrete floor.

You are essentially painting a concrete floor after all. A damp proof membrane dpm is a membrane material applied to prevent moisture transmission. Inserted in between the hard core and concrete floor this impermeable layer will prevent rising damp. The easiest solution for damp proofing concrete floors is to install a plastic membrane.

This barrier is intended to stop moisture passing from one to the other. The epoxy dpm comes as a two component system. Either a damp proof coating can be applied to the surface of the concrete or a damp proof membrane can be laid on top of the concrete. Essentially this is a plastic mesh sheet specially formulated to ensure that moisture cannot penetrate.

Assuming that the damp proof membrane dpm under the concrete has failed in areas then yes you possibly would get the odd patch of dampness showing in the floor. If there was no dpm i would suggest a uniformal distribution across the whole floor. It sits between the concrete and the underlay floor covering. But it is an effective way to do it.

Once the liquid membrane has been applied to the concrete and it dries an extremely hard surface is created that is impenetrable for damp. It might seem a bit unusual. If in budget you should look at getting a new concrete floor poured. Most damp proof floor coatings are applied directly to the concrete floor surface using a brush or roller.

It is low odour solvent free and most importantly deals with constant low levels of moisture in concrete floors. There are however two options for damp proofing concrete floors without needing to replace the floor itself. A liquid applied dpm damp proof membrane is a simple solution and an excellent way to damp proof a concrete floor. You also mentioned that there are vinyl tiles over the floor.
