How To Lay A Concrete Floor With Damp Proof Membrane

Most damp-proof floor coatings are applied directly to the concrete floor surface using a brush or roller.

How to lay a concrete floor with damp proof membrane. All types of floor coverings can be installed on top of a plastic membrane. A damp-proof membrane is put down. In order to resist degradation insulation placed below the damp proof membrane should have low water absorption.

If necessary the insulant should be resistant to contaminants in the ground. The Drybase range of liquid-applied coatings including Drybase ECS Epoxy Floor Coatings and Drybase Liquid-Applied DPM can be applied directly to damp floors to create a damp-proof barrier without raising the floor level. Essentially this is a plastic mesh sheet specially formulated to ensure that moisture cannot penetrate.

All types of floor coverings can be installed on top of a plastic membrane. There should be a damp proof membrane under the concrete slab already but it might be damaged if there is moisture on the slab. The next membrane width is rolled out so that the edges of the membrane overlaps.

Installing a damp proof underlay for concrete floors. It sits between the concrete and the underlay floor covering. If the house is older or there is a doubt regarding possible moisture in the concrete subfloor then laminate can be laid on a bituminous reinforced underlay designed for that purpose.

Preparation is key with these coatings and the substrate must be sufficiently clean and dry. Indoor and outdoor use An acrylic brush-on membrane Dunlop Damp-Proof Waterproofing will prevent rising damp efflorescence and will resist negative hydrostatic pressure. If your house is relatively modern there will be a damp proof membrane below the floor.

The easiest solution for damp proofing concrete floors is to install a plastic membrane. Insulation sheets should be laid tightly together with the joints staggered to avoid movement. It has excellent adhesion to most substrates including brick masonry concrete block concrete stone and timber and is simple to apply with a brush or roller.
