Buildings often face two major types of problems which are mainly rising damp and penetrating damp, if not properly dealt with both can lead to a series of significant problems. For better understanding, damp literally rises from the ground to a level of about 4 feet and does not go up higher from there.

What we can do

Firstly, we determine the level of the problem, we check whether any moisture is actually damp and not water penetration, in cases of water penetration, some repairs are necessary. Secondly, we check how deep the problem has evolved. For instance, if you detect a damp patch, gently trace it in pencil and see whether it grows or diminishes over time with changes in the temperature or weather. And then decide how to fix the problem.

Damp Proofing Can Help Prevent

  • Rising / Penetrating Damp
  • Ingress of Water
  • Salt Crystallization
  • Plaster Breakdown
  • Damp Staining
  • Wet Rot / Dry Rot

What is a damp-proof course?

A damp-proof course (DPC) is a layer typically of bituminous plastic which is set up underneath the wall where the floorboards are located, in the space between the ground and the inside floor. A damp-proof course is one of the different damp proofing treatments used to avert damp problems evolving within a property. If for some reason a DPC is not rightly installed, it certainly will not work and will allow damp into your house.

Damp proof course repair is applied using a variety of methods which is a long-term solution to prevent dampness from entering through the walls of a property. Excessive dampness within a building or property can lead to structural damage as well as pose further danger to the property.

Insert or repair a damp-proof course?

The most popular way to rectify a damaged damp-proof course is for a damp specialist to drill holes in the wall and introduce damp-proof cream to function as a new course. Although different solutions can be proffered, like cutting grooves into the brickwork and introduce a piece of damp-proof course instead of a chemical approach. This is better than drilling holes and can be comfortably hidden. Our damp page regularly displays the prices of these jobs.

What is a damp-proof membrane?

A sheet of material impregnable to water placed in one piece that is set below the concrete floor of a building to intercept groundwater going through the concrete base. A vivid example is polyethylene sheeting set under a concrete slab.

Repair or replace a damp-proof membrane?

In cases of a small patch of damp on the floor, it could be remedied by painting over the patch in order to halt further water from coming through. Two coats of bitumen latex waterproof emulsion should be applied below the floor which can be bought from different DIY stores. some experts advocate laying reflective foil building paper for extra protection.

This is applicable to minor cases, dealing with excessive dampness, the damp-proof membrane may need to be replaced entirely which is likely to be costly but necessary if other solutions have proven abortive.

Information about London


Must I remove the plaster before applying the membrane?

Depends. If you have a cement render, your wall is made of hard, good sand and can withstand the drilling, then you don’t have to remove it. However, if you your wall has Bonding plaster and Gypsum, then you have to remove it.

Can I use a Membrane if my wall is old and rough?

Absolutely. If your wall is loose, uneven, or out of line, a timber ‘stud’ frame will hold the Membrane in place.

When is a Membrane used?

Usually below the ground like in a cellar or basement. But it can also be used above the ground in cases of ‘salts’ problem, stained chimney breast or a cold wall.
