This DPC is suitable for masonry walls and has a diamond embossed surface to offer better mortar adhesion. It should be noted that breaches of the 150mm rule are the sort of thing that is noticed by Surveyors when valuing a property and it can lead to a reduced valuation or a requirement for remedial work to be undertaken. and just to confuse matters, there are a couple of traits that can confound the hunt for the dpc.... If renovating after a pre-existing damp problem, consider installing fresh sawn & carcassing timber to replace rotten stud work and battens. The polyethylene DPC used in the manufacture of ARC Insulated DPC conforms to the requirements of BS6515.

A DPC should be provided a minimum 150mm above adjoining surfaces and linked with the DPM in solid floors. DPC (Damp proof course) is used when a physical barrier is required to prevent moisture travelling up building walls. Most existing constructions should have a form of DPC already in situation, however this product will be required for new wall constructions to prevent an issues with rising damp. The Visqueen Polyethylene Damp Proof Course is made to the minimum damp proof course standard set by the British Standard, offering you a more cost effective but still trade suitable option. The polyethylene foam insulation used in ARC Insulated DPC has a thermal conductivity of 0.039W/mK.

Installation should be according to the code of practice CP102:1973 and normal DPC good practice procedures set in BS 5628 should be followed. The reveal should be protected throughout its width by a continuous DPC. The width of the DPC should be sufficient to be fixed to, or overlap, the frame and fully protect the reveal. For very severe exposure conditions, rebated reveal construction or a proprietary closer, suitable for the conditions, should be used. Jewson building materials can make sure you have everything you need to not only install a damp proof course, but to complete the job from start to finish. The Building Regulations require at least 150mm between the dpc and the ground or any paving. This is what is known as 'Best Practice'. However, there are situations where it is just not possible, or practical, to maintain this regulation. On professional work, and new build projects, every possible effort should be made to ensure the 150mm rule is not breached, but, for small, domestic projects, such as a driveway or patio, there are cases where keeping the paving to 150mm below dpc would involve a huge amount of work that cannot be justified. In such cases, the 150mm rule can be 'bent' a little, but with the following provisos... Unfortunately, We Cannot Guarantee Next Working Day - you will be notified if we can't fulfill this.
