Black Embossed Polythene Damp Proof Course for Wall Used with Good Price

Damp proof course

A 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 polythene Damp Proof Course waterproof material 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's 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.

Thickness usually 0.5mm,  0.7mm

100mm x 30m /roll

150mm x 30m /roll

220mm x 30m /roll

450mm x 30m /roll

600mm x 30m /roll 

The DPC can be used in both vertical and horizontal applications to restrict upward and horizontal moving water within structure walls.


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.

Installation

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.
