WATERPROOFING MEMBRANE MANUFACTURER
Damp proof course ( DPC ) waterproof material is a physical barrier inserted into the fabric of a building to stop water passing from one place to another.
Embossed damp proof course can be on a horizontal plane, stopping water rising up from the ground by being sucked up by the dry masonry above, or vertically to stop water passing from the outside of a building, though the masonry, to the inside.
DPC have taken many forms through the ages and one of the earliest forms was to use a layer of slate in the construction. Slate is still used but the less expensive plastic version ( below right ) is now more widely used.
*Packing: 150mm x 30m (4.5㎡/roll)
*The thickness, width, length can be made based on customers’ requirements.
• The DPC can be used in both vertical and horizontal applications to restrict upward and horizontal moving water within
• DPC is unsuitable for use in applications that places high sheer stress on the DPC, such as restraining walls or high flexible
stress, such as freestanding walls and parapets.
• The DPC should not be used to restrict the flow of downwards moving water such as above lintels or within cavity walls.
• Suitable for use all year round, this DPC is a highly versatile product and is subject to stringent quality controls to
meet all British Standards.
• Embossed to assist mortar adhesion.
• Durable with proven performance over many years.
• Manufactured from the highest quality reprocessed materials.
• Remains flexible – even at low temperatures.
• Safe and clean to handle.
• Suitable for use in horizontal and vertical applications throughout domestic construction.
Installation should be according to the code of practice CP102:1973 and normal DPC good practice procedures set in BS
5628 should be followed.
Some brief guidelines on how to use the DPC are supplied below:
- For external walls the DPC should be applied 150mm above the adjoining surface and should be linked with the DPM in
solid floors. The DPC should be applied to a fresh bed of mortar, completely free of projections that may puncture the material
or impede the DPC from lying flat. When joining two pieces of DPC they should be lapped over each other by at least 100mm.
- For internal walls, DPC should be installed at the base of load bearing walls and linked with any adjoining DPM. The DPC
should be at least the width the partition it is applied to and lapped by at least 100mm when two DPC's are joined.
