If you’re searching for ‘damp proofing Bath’, it’s likely that you’ve discovered damp on walls in your home. It is essential that a comprehensive damp survey is completed prior to any work being carried out around your home. With comprehensive damp surveys carried out across South West, our damp specialists have surveyed hundreds of cases of moisture ingress and damp problems in both domestic and commercial buildings.

The widespread issues of poor surveying and misdiagnosis of damp problems have led to ineffective damp solutions and poor quality damp wall treatment. The failure to identify the causes of damp can not only prove costly when spending money on poor quality surveys and treatments but also to further costs required to rectify the structural damage caused to walls and other parts of the building.

At Biocraft South West, you’re in safe hands. Our experienced team of qualified surveyors have carried out hundreds of comprehensive damp surveys and treated varying types of damp and moisture ingress. Our surveys start with external examinations of the property to identify any potential damage caused to brickwork, roofing or windows and doors. All of our surveys outline the most effective damp treatments you’ll find when searching for damp proofing Bath.

Types of Damp Proofing in Bath

The types of damp treatment required will always depend on the results of the damp survey conducted on your property. The findings outlined in the damp survey report will allow our team of surveys and remediation team to take fast and efficient action. With types of damp ranging from rising damp and penetrating damp, to timber related moisture ingress such as wet rot.

For example, the treatment involved for rising damp first requires the need to completely eradicate the source of moisture from your property. One of the most effective and common methods of containing rising damp is by injecting a specialised chemical damp proof course into the base wall of the building. Where necessary, compromised plaster will be replaced with a damp proof, cement-based render that will hold back and future moisture and residue. This will prevent the new layer of plaster and paint from being compromised and holds back any future moisture that would otherwise be present.

The process of installing a new rising damp can be an expensive and potentially dangerous task. As one of the most effective methods to eliminating rising damp, the application of a chemical damp course will transform your existing wall structure into a waterproof barrier.

Condensation Control

Dampness and mould around the home can often be attributed to non-damp factors from external sources. As winter creeps in, thousands of homes throughout the UK will no doubt be affected by condensation. Present in even the best built and insulated properties, high levels of condensation can lead to mould and damp on walls around the home.

More often than not, condensation control does not require the immediate attention of a damp specialist, and there are some processes you can carry out around your home to reduce the impact of condensation. With the average home generating between 10 and 20 litres of moisture every day (from cooking, bathing and even breathing), simply opening a window, using a basic ventilation system, and frequently turning on the heating can prevent moisture buildup and mould growth. If your condensation problems persist and you’re searching for ‘damp proofing Bath’, call us today to book a comprehensive damp survey.

At Biocraft South West, our experts have compiled a range of tips and tasks you can carry out that will help prevent condensation in your home.

Rising Damp

When people encounter damp patches in their homes, they often refer to this is ‘rising damp’. Despite this, rising damp isn’t the most common form of damp within the home. However, you are likely to find rising damp in much older homes that have had poor or no damp proofing installed. If you have an older property and require damp proofing in Bath, contact our team today to book a survey.

A building or structure becomes affected by rising damp depending on several problems. This includes groundwater levels, pore structure of materials used to create walls, as well as the evaporation rate away from the wall’s surface.

Caused by the absorption of groundwater into porous building materials, rising damp can often rise into walls at a height of 1.5m – depending on the porous materials used and their susceptibility to groundwater.

Hygroscopic Salts

When rising damp draws groundwater into the structure of a building, it can often bring damaging salts with it. These ‘hygroscopic salts’ are attracted by the moisture and include high levels of chloride and nitrates that can contaminate and destroy plasterwork.

If these salts become present in walls and fixtures around your home, it becomes easier for moisture in the air (and additional rising damp) to enter the wall structure. Hygroscopic salts become an issue even after rising damp has been successfully treated with a course of chemical damp proofing. This makes it essential that specialist replastering is carried out as part of the comprehensive treatment process.

Effectively Treating Rising Damp

To successfully and comprehensively treat rising damp, it’s imperative that all sources of moisture are first treated. A common method of treating rising damp is by applying a chemical damp proof course into the base of affected walls. Once the damp proof course has been applied, all walls and plaster that have been affected by hygroscopic salts will be replaced with a specialist cement-based plaster. This cement-based plaster will hold back any future moisture & subsequent hygroscopic salts that remain present in the wall structure.

A damp proof course can be seen as a ‘horizontal barrier’ that runs across the base wall of the building and prevents the advance of rising damp in homes. Whilst older buildings have previously had a physical damp proofing applied, they can often become weak and deteriorate over time due to the materials used. Older damp proof courses often prove ineffective when suppressing rising damp, which is why a new chemical course is applied.

When applying a new damp proof course it should be installed no lower than 150mm above external ground level. This will remove any risk of potential ‘splash back’ from these external surfaces. We have often carried out work on properties that have had poorly installed courses that have resulted in the damp proof course being bridged by lower levels of penetrating damp.

At Biocraft, we have provided hundreds of damp proofing solutions to homes throughout Bath and surrounding areas. Our teams’ extensive knowledge, understanding and diagnosis has proven to eliminate and successfully treat rising damp and other damp issues.
