Damp proofing is defined by the American Society for Testing and Materials (ASTM) as a material that resists the passage of water with no hydro-static pressure and waterproof as a treatment that resists the passage of water under pressure. Generally damp proofing keeps moisture out of a building where vapor barriers keep interior moisture from getting into walls. Moisture resistance is not necessarily absolute: it is usually defined by a specific test method, limits, and engineering tolerances..

Damp proofing is accomplished several ways including:

A damp-proof course (DPC) is a barrier in a masonry wall designed to resist moisture rising through the structure by capillary action such as through a phenomenon known as rising damp. The damp proof course may be horizontal or vertical. A DPC layer is usually laid below all masonry walls, regardless if the wall is a load bearing wall or a partition wall.

A damp-proof membrane (DPM) is a membrane material applied to prevent moisture transmission. A common example is polyethylene sheeting laid under a concrete slab to prevent the concrete from gaining moisture through capillary action. A DPM may be used for the DPC.

Integral damp proofing in concrete involves adding materials to the concrete mix to make the concrete itself impermeable. Surface coating with thin water proof materials for resistance to non-pressurized moisture such as rain water or a coating of cement sprayed on such as shotcrete which can resist water under pressure.

Cavity wall construction such as rain-screen construction, is where the interior walls are separated from the exterior walls by a cavity. Pressure grouting cracks and joints in masonry materials.

Iron Resources Limited – sole distributor in Nigeria and Africa exclusively introduce WYKAMOL Products for treating dampness in your homes. WYKAMOL is UK leading manufacturer of specialist products partnering with Iron Resources Limited to proffer solutions to dampness in our homes.

Dampness is the presence of unwanted moisture in the structure of a building, either the intrusion from outside or condensation from within the structure.

High Proportion of Damp problems in buildings are caused by condensation, rain penetration, or rising damp which is harmful to human health as it poses several threat such as Asthma, presence of bacteria etc. Most form of dampness can either be prevented or corrected by employing preventive and corrective measure/control.

Iron resources bring to your door step solutions to your persistent dampness problems.
