Delta ventilated waterproofing systems are recommended for above ground situations or in areas where no free running water is expected, for example where external pavements have been built up.

Ventilated system have an air gap at top and bottom. All joints and fixings are sealed. This method is a sympathetic solution in Heritage properties as a general damp proofing system. The fabric of the building remains unchanged but the internal surfaces are ‘dry’ and are salt and contamination free. Both dry lining or plaster direct finishes are available for use on ventilated system. Delta technical staff provide full technical support and advice.
