Product Information

and just to confuse matters, there are a couple of traits that can confound the hunt for the dpc.... 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... 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. Damp proofing membrane is sometimes called DPM for short, or DPC membrane as shorthand for 'damp proof course membrane'. A damp course is not the only method of damp proofing for the home. Our range of damp proof products also includes chimney pots, which can help to keep adverse weather from entering the property via the chimney.

For more information about preventing cold bridges, refer to our Registered Construction Details. 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. This DPC is suitable for masonry walls and has a diamond embossed surface to offer better mortar adhesion.

A cavity tray should be provided to direct any water that enters the cavity to the outside. The cavity tray should fully protect the opening.

Features & benefits

The polyethylene foam insulation used in ARC Insulated DPC has a thermal conductivity of 0.039W/mK. A variation on the workaround illustrated above. On the left-hand side, a pre-cast concrete edging has been used to create the retainer and the paving is significantly higher than the dpc. A dished channel unit has been used at the base to direct any surface water to the gullies. Although a relatively narrow channel is shown here, these 'dry area' solutions can feature much wider channel, often 600mm or more, and so consideration must be given to safe-guarding the edge to prevent accidental falls.
