Some specialists have been treating damp brickwork and stonemasonry for over 40 years, but to the average homeowner the methods of treatment can seem like something of an enigma. The type and extent of the problem determines which method of damp proofing Coventry is employed, but whichever technique is used, customers can have confidence in the time honoured success and seasoned technicians of companies with this level of experience. But before you enlist the help of an expert like this, it stands you in good stead to research the issue. With this in mind detailed below are the most common damp proofing methods.
Damp occurs when moisture from the ground penetrates brickwork and works its way upwards. The techniques below are designed to prevent this from taking place at all, or to halt the continued rise of damp.
Chemical Damp Proof Course
This technique is by far the most common type used in the industry due to the hassle free way in which it is implemented, and lasting results afforded. The method basically involves injecting a formula into the affected masonry via the mortar joints; this then seals the brickwork and prevents damp from penetrating further.
Advantages include the fact that the chemical used is odourless and eco-friendly, although be aware that the specialist you employ must work in accordance with the British Standard Code of Practice for Installation of Chemical Damp Proof Courses (BS 6576:1985)
Porous Tube Damp Proof Course
This method is less common, and is less reliable than chemical applications. It involves inserting porous clay tubes into the joints of a wall at a height of 6 inches above the ground. The idea is that the tubes facilitate enhanced levels of evaporation and as such reduce the amount of damp present. This method is not usually recommended when chemical damp proofing is available.
Electro-osmotic Damp Proofing
This high spec technique involves bedding electrodes in the affected wall and running an electric charge through it. The negatively charged electrode is placed at the base of the wall in order to attract the water molecules toward the ground. This technique is effective but rarely required.
Most damp proofing Coventry can be achieved using a chemical damp proof course, or using a solid damp proofing layer during the initial construction of the brickwork. If you have any questions regarding the best method for your home there are industry experts available who can help.
