Bitumen Floor Dpm

There is no membrane beneath your floor or any others of this period.

Bitumen floor dpm.

Dries black drying time. Rfc liquid damp proof membrane dpm is a professional 2 component applied surface primer. Can be used on walls and floors to prevent water ingress and dampness from the ground. Moisture ingress can potentially result in timbers rotting and long term structural damage.

Importance of bitumen for damp proofing. Water based rubberised bitumen emulsion for internal and external use. Drybase liquid applied dpm should be used in situations where the final surface is going to be covered. Like a lot of houses of that age the ground floor is bitumen asphalt over a concrete screed.

The excellent adhesive qualities and quick drying time of drybase liquid applied dpm make it extremely versatile. I m doing a kitchen modernisation in my ex council house which was built in 1947. 4 6 hours coverage. The marley tiles and bitumen acted as a dpm of sorts.

In older properties this can break down. The damp course will exist in the walls only. It can t be emphasised enough weather proofing and damp proofing helps prevent damage to a property. Pity you took the screed off as like me you have an inch to build back up.

I own a 1960 s bungalow and when we first moved in we found it had an old fashioned very brittle bitumen dpm which had failed in a number of places. Furthermore damp can result in condensation and black mould. The bitumen is about 20 mm thick and i believe serves as moisture barrier as well as an appearance finish. A mastic asphalt floor or deck varies in thickness and grades dependant on its use typically 10 20mm thick when used as a moisture suppressant it is normally poured over a separating membrane technically it becomes a floating subfloor.

It has excellent adhesion to damp cementitious surfaces and once dried provides a dry barrier against moisture below. Usually but not always a damp proof course means a dpm is present. Look at my posts and you may see images of mine. Xi r34 r35 r36 r37 r38 r50.

There was evidence of damp in places and the whole slab was damp. Small domestic areas that are going to have carpet wood or synthetic floors as the final surface are ideal to use in conjunction with the liquid applied dpm.
