Rising wall Dampness
Rising damp treatment
Rising damp is the upwards absorption of groundwater through a porous wall by a process called capillarity. The severity of Rising damp is dependent on the level of groundwater, the pore composition of the masonry materials used in the structure and the rate at which moisture evaporates from the wall. The effects of rising damp on a building include: Causing damage to decorations like blisters to paints and the decay of plaster; the destruction of the buildings micro-structure by the ground salts that rises with the moisture causing loss of structural integrity and some health challenges like rheumatism and colds for occupants of the building.
Treating rising damp
Fix your Damp
Rising damp is an age long problem that is often misdiagnosed. The presence of a tide mark at the peak of the rise caused by rising salts is key, but we look beyond this sign. It is important that a review of the environment for standing water is done and possibly a construct of an appropriate drainage. We thereafter check for the presence and effectiveness of your damp-proof course.
The most popular and often practicable method of treating rising damp is through a damp proof injection. At Advanced damp, we have perfected rising damp treatment with a process, shown to be the most reliable guard against rising damp. As the most cost effective rising damp treatment, our damp proof injection uses the industry best products.

A thorough survey of the damp
At Advanced damp, we recognise that Rising Damp has continued to be a challenge often misdiagnosed by unqualified contractors. Our team of certified damp specialists will investigate and identify the source of the dampness. Though a process of investigation and elimination, we will ensure that there is a proper diagnosis of the challenge as the first step towards solving it.
Though Rising damp is often characterised by a ‘tide mark’ on the lower section of the affected wall caused by soluble salts, we recognise that other damp conditions can present similar symptoms. This a ‘tidemark’ may run horizontally along the wall and an obvious damp area below it. Basically, excessive moisture at the base of the wall which gradually declines further up points to rising damp as the cause of the damp. Electrical moisture meters could also be used at internals for a moisture profile of the affected walls. Our surveyors are not only highly trained but are also certified by relevant certification institutions, to accurately analyse and identify the reasons of your damp problems.
Rising Damp treatment Hertfordshire
Prepare the area and take out any salt polluted plaster from the walls
Rising damp transports salts from the ground water into the building structure. Sometimes these are moisture attracting salts, which, when accumulated can attract moisture from the air and compound the existing problem. These salts can further damage the masonry and plaster of your building as they tend to expand when they crystallize. Our team of experts will ensure that these residual salts are expunged from your wall and already damaged plaster and masonry repaired. Our plaster removal is often to a height of about one meter, exposing the brickwork. This is meticulously done after we have removed and properly isolated any fixtures and fittings on the affected walls, both externally and internally. We assure you that this process will not affect your floor coverings or any installations whatsoever.
how to fix rising damp?
Install the damp proof course
If we discover that your damp proof course has failed for whatever reason, our team of experts will recreate a damp proof course of your building by damp proof injection. As a means of solving your rising damp challenge, it involves the injection of our highly effective cream, a concentrated thixotropic silane, siloxane cream into the mortar bed joint of your wall. Having invested over 60 years in research, perfecting our rising damp treatment, it creates a leak-proof resin within your wall as it dries up. Our system is made from specialised chemicals that uniformly allow silane, its active element, to be properly absorbed and block the capillaries before drying.
