Damp proof floor insulation.

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. Drybase products have the advantage of being extremely easy to apply. Most damp proof floor coatings are applied directly to the concrete floor surface using a brush or roller. Preparation is key with these coatings and the substrate must be sufficiently clean and dry.

Drybase liquid applied damp proof membranes. When constructing an extension or a new build home it is important that damp proofing measures are taken during the initial construction phase itself. Then lay moisture. These days damp proof membranes are required in the construction of all new buildings to prevent rising damp.

These systems which continuously monitor key performance criteria along with a strict selective raw material policy ensures a consistently high quality dpm. They can be purchased from larger diy stores. Where a dwelling is extended care should be taken to link the new floor dpm to the existing building dpm and to the wall. Lay the damp proof membrane onto the concrete followed by the insulation.

Laying a continuous damp proof membrane beneath the insulation is advisable taking care to overlap with any damp proof course in the external walls. Damp proof membranes can come flat or in rolls that look a bit like a big bin liner roll. The insulation is usually fitted above the damp proof membrane with a separation layer above the insulation. Sometimes the issue can be bridging of the damp proof course by the concrete floor assuming is was timber prior as this often occurs.

Liked by the question poster. Which type of coating is chosen will depend on the intended use of the floor.

Damp proof membrane is manufactured from high quality reprocessed low density polyethylene.

Solution would be get that floor up then the real cause would be revealed and the floor can be replaced with a dpc and insulation. Bre building research establishment is an independent research based consultancy testing and training organisation operating in the built environment and associated industries. Construction insulation and damp proofing designing buildings wiki share your construction industry knowledge. Damp proofing concrete floors above ground damp proofing for extensions.

When installing insulation on top of the concrete floor the most common method of installation is as follows.
