In certain circumstances replastering of walls following chemical d.p.c. insertion is not feasible, e.g. friable
wall surfaces, uneven wall profiles etc. Where dry lining is to be carried out this should be in accordance with
the manufacturers' recommendations. Care should be taken to ensure that gypsum adhesives are not used
in 'dot and dab' applications directly onto the wall surface. Timber used as battens must be pre-treated and
all cut ends re-treated on site. Ventilation should be provided behind the system until the walls have dried out
to reduce the possibility of condensation within the void.
Where high levels of salt contamination are present, or suspected, or where walls are persistently damp due
to the presence of high concentrations of hygroscopic salts further preparation may be required. In such
cases reinstatement can proceed in conjunction with a ventilated dry lining system based on a high density
polyethylene (HDPE) membrane which provides a vapour impermeable surface suitable for conventional
plastering and/or dry lining techniques. If doubt exists as to the extent or nature of the salt contamination, we
should be consulted.
We are experts in timber treatment, condensation cures, damp proofing and cellar conversions. We work in London and throughout the Home Counties area, mainly in Essex and Hertfordshire. We are a well-established family firm, and have built our business on our good reputation. Our work is carried out by our own staff and is usually backed by a long-term insurance-backed guarantee.
Condensation occurs when warm moist air comes into contact with a cooler surface. If the surface temperature is at or below the point where moisture vapour held in the air condenses, the Dew Point, then water droplets form on the surface.
