Damp Proofing to Prevent Rising Damp

The presence of unwanted moisture in the structure of a building (structural dampness), is the result of intrusion of moisture from outside or condensation from within the structure. Damp problems within buildings are mostly caused by condensation, rain penetration or rising damp. Unwanted moisture causes secondary damage to buildings by enabling the growth of various fungi in wood, causing rot or mould, plaster, paint and wallpaper deteriorate. On the exterior of the building, salt stains may appear on the walls and mortar may crumble. Damp proofing resists the passage of water with no hydrostatic pressure.

AWS Services can provide you with:
  • A damp-proof course – A barrier in a masonry wall designed to resist moisture rising through the structure by capillary action such as through rising damp.
  • A damp-proof membrane – Polyethylene sheeting laid under a concrete slab to prevent the concrete from gaining moisture through capillary action.
  • Integral damp proofing – Putting additives into the concrete mix to make the concrete itself impermeable.
  • Surface coating – Using a thin waterproof material for resistance to moisture.
  • Cavity wall construction – Where the interior walls are separated from the exterior walls by a cavity.
  • Pressure grouting – Injecting a grout material into the structure.

AWS Services have tradespeople who specialise in damp proofing for your home, we will assess your needs and provide you with the damp proofing solution that is right for you.

Causes of Rising Damp

Rising damp (salt-damp) occurs on the bases of walls and moves upwards vertically. It occurs when the damp proof course, that all houses are required to be fitted with, is not doing its job and stopping the moisture from rising. Rising damp can be caused by: 

  • A damaged damp proof course.
  • Inadequate sub-floor ventilation.
  • Sub-floor obstructions.
  • Poor drainage or damaged guttering and pipes.

Rising damp is a genuine issue and should be handled by professionals who can assess the source of the problem and provide you with the most effective solution.
