Damp proofing concrete floors above ground damp proofing for extensions.
How to lay damp proof membrane concrete floor.
When constructing an extension or a new build home it is important that damp proofing measures are taken during the initial construction phase itself.
Insulation is put down.
Concrete is poured and left to cure for a minimum of three days.
Most damp proof floor coatings are applied directly to the concrete floor.
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.
Damp rising through concrete floor slabs is fairly common causing damp issues on carpets and floor coverings warping wooden floors and increasing the likelihood of low level mould growth.
The damp proof membranes used during construction of concrete floors are often thin and can easily become torn before they are laid rendering them.
This is due to the fact the membrane can be applied onto the damp surfaces so there is little surface preparation that needs to be made.
This is more than often an easier and quicker option than using a damp proof coating.
Damp proofing concrete floors with liquid membranes.
You are essentially painting a concrete floor after all.
Plastic damp proof membrane.
A liquid applied dpm damp proof membrane is a simple solution and an excellent way to damp proof a concrete floor.
It might seem a bit unusual.
This barrier is intended to stop moisture passing from one to the other.
The second option is to use a damp proofing membrane on top of the existing concrete surface.
But it is an effective way to do it.
There are however two options for damp proofing concrete floors without needing to replace the floor itself.
Approximately 1 400 including labour beam and block floors.
