Dampcourse

Specifications

1. Introduction:

Damp proofing in construction is a type of waterproofing applied to building foundation walls to prevent moisture from passing through the walls into interior spaces.

2.Usage:

A damp-proof course (often abbreviated to DPC) is a horizontal barrier in a wall designed to resist moisture rising through the structure by capillary action - a phenomenon known as rising damp.

3.DPC:

In simpler words, DPC is used to stop dampness in buildings. In theory, due to capillary movement of water, water rises from earth to the building. Passing through foundation it rises higher to reach walls. Reaching water to walls may damage them by creating cracks, breaking cement-paint bonds and creating dark-spots on wall etc. So, to avoid water from reaching to walls, we lay DPC layer at plinth level (the joint level of walls and foundations). DPC layer is usually laid below all the walls unaffected from the issue that the respective wall is a load bearing wall or a partition wall.

A damp proof course ( DPC ) is a physical barrier inserted into the fabric of a building to stop water passing from one place to another. This 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
