Bond-It Damp Proof Course (DPC) Membrane 100mm X 30 Metre roll - Flexible, Durable, Safe and Clean to Handle Meets BS6515. Embossed to Assist Mortar Adhesion - Cost Effective dpc, Black, DPC100

Product Information

This DPC is suitable for masonry walls and has a diamond embossed surface to offer better mortar adhesion.

Our metalwork wall & frame ties are ideal for work on cavity walls, to hold everything securely together once your damp course is in place. A DPC should be provided a minimum 150mm above adjoining surfaces and linked with the DPM in solid floors. Preformed stepped cavity trays should be provided above the roof surface and linked to the roof upstand or flashing to ensure any water penetrating into the cavity does not enter the enclosed area. 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.

The polyethylene DPC used in the manufacture of ARC Insulated DPC conforms to the requirements of BS6515.

The polyethylene foam insulation used in ARC Insulated DPC has a thermal conductivity of 0.039W/mK. and just to confuse matters, there are a couple of traits that can confound the hunt for the dpc.... 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.

The DPC also features an embossed finish to make mortar adhesion better. How to install a DPC membrane 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. A cavity tray should be provided 150mm above any adjoining roof or balcony surface. The tray should be lapped over any roof upstand or flashing to ensure water penetrating into the cavity does not enter the enclosed area. 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. This DPC is extremely durable and is guaranteed to meet British Building Regulations. It is manufactured from 100% recycled polythene materials, making it an environmentally friendly option too.

Use of an insulated cavity closer would have prevented these last 2 problems. For more information about preventing cold bridges, refer to our Registered Construction Details. Damp proofing membranes protect different parts of a structure from damage arising from damp, including mould and mildew, and the risk of rotten timber.

DPC installation is simplest in the new construction process. For external walls, the DPC should be applied 150mm above the external ground level. You need to ensure it is linked with the DPM in solid floors. The paving/ground level should always be at least 75mm below the DPC. Anything less than that is just asking for trouble.* Just solid masonry separated by a vertical DPC. This means that this part of the wall will be colder that the rest of the wall, resulting in condensation forming around this part of the structure – a case of ‘cold bridging’. Judging by the standards of workmanship, it’s quite likely that there is no insulation below the DPC either, meaning the same problems will happen around the skirting too. It’s important to think about cold bridging through any part of the structure but especially where junctions occur. Further information
