Most forms of dampness can be prevented by thoughtful building design and careful construction. In the UK, well built modern houses include DAMP PROOFING in the form of a synthetic damp-proof course (DPC), about 15 cm above ground level, to act as a barrier through which water cannot pass. Slate or "engineering bricks" with a low porosity were often used for the first few courses above ground level, and these can help minimise the problem.
There are many approaches to the treatment of dampness in existing buildings. Key to the selection of an appropriate treatment is a correct diagnosis of the types of dampness affecting a building. Details of possible treatments for specific types of dampness are covered in the the reports we supply
The cause of the dampness must first be eliminated, sometimes providing better drainage or fixing leaking pipes are the solution. BRE Digest 245 describes several methods of treating rising damp, including the use of land-drains and the insertion of physical and chemical DPCs. Then, any affected plaster or mortar must be removed, and the wall treated, before replacing the plaster and repainting. we are certified to use all BBA [british Board of aggregates] approved material all which meet the green standard of approval.Damp tech part of V Build offer all our knowledge to help solve your damp issues before injecting or any apply brick creams are applied .
Rising damp treatment
In many cases, damp is caused by "bridging" of a damp-proof course that is otherwise working effectively. For example, a flower bed next to an affected wall might result in soil being piled up against the wall above the level of the DPC. In this example, moisture from the ground would be able to ingress through the wall from the soil. Such a damp problem could be rectified by simply lowering the flower bed to below DPC level.
Where a rising damp problem is caused by a lack of a damp-proof course (common in older buildings and new poorly built properties) or just by a failed damp-proof course there are a wide range of possible solutions available.

What is Masonry Protection Cream?
IT is a deeply penetrating water repellent cream for brick, stone, and concrete. Due to its cream-based formulation it is able to penetrate more deeply into masonry than standard liquid-applied water seal products.
It is based on proven silane/siloxane technology and works by lining the pores of the masonry rather than blocking them - allowing the wall to continue to breathe. This is in contrast to many standard brick sealer and stone sealer products which coat the masonry with a thin film.
Only a single coat application is required - many competing water repellent products require two coats.
Our BBA material is the only colourless masonry water repellent treatment that carries BBA approval (cert. number 15/5198). After extensive testing to determine continued water-repellency after aggressive freeze-thaw and UV exposure, the BBA issued a certificate with the followiung durability statement:
the product will remain effective as a masonry water repellent for 25 years.So thats keeping your property dry and warmer for 25 years product guarantee thats outstanding and Energy Saving
By providing in-depth protection against moisture ingress,Tests carried out by the University of Portsmouth demonstrate that energy savings are possible by keeping walls dry using Stormdry. This is because dry walls are better insulators than wet walls.
