Damp Concrete Floor Problem? "No Such Thing!"

We all know that excessive moisture/damp and timber floors do not go together. Generally the more expensive the timber the more it gets affected.

So there we are, turning work away because:
a) The concrete sub floor is too new and still needs to dry for at least 50-60 days.
b) The existing floor we are looking at shows obvious signs of dampness.
c) We have done our moisture content test of taping a square of polyethylene to the floor and finding after removal that the area is discoloured with evidence of water droplets on the underneath of the film, or if available we carry out a deep probe Protimeter test, which only proves the former. You may wish to continue with the contract and suggest that you: -

Lay a 1000 gauge d.p.m. down first but this may increase the problem, as it is not


vapour proof and causes sweating, not to mention the relative short term life span of polythene; Or a two coat epoxy floor covering, but this is expensive and requires a drying time thus delaying the floor installation and putting the room out of commission. Alternatively, you may have heard of Cavity Drainage Membrane systems which have been used for damp-proofing, and in aggressive water situations below ground for waterproofing.

For general floor use, where there is only a capillary or residual moisture problem, which would affect timber flooring, screeds or other finishes, Delta offer either Delta-FM or Delta-MS grades of membrane.

Both are specifically designed for floor applications, to combat dampness, and contamination. The special low stud profiles (3mm) of Delta-FM or (8mm) of Delta-MS minimizes changes in floor levels, but still provide an air gap to achieve damp pressure equalization.



The membranes are a
fast-track solution allowing
various floor finishes to
be achieved with zero
'down time'.

The %R.H. Levels are isolated in the air gap, and
controlled. Delta
membranes can be used
in new build, remedial or
refurbishment projects for
floors, and walls.
