At Brit Rem Ltd, we’re proud to provide our customers with a range of bespoke solutions for rising damp.
Rising damp is often one of the main causes of structural damage in properties. For example, internally rising groundwater can saturate walls with saltpetre which damages building materials. Most importantly, constant dampness can lead to a wide variety of defects such as mould, damaged render and even the peeling of wallpaper and paint. Now when it comes to combatting rising damp, we offer a wide range of solutions to help make sure your property remains structurally sound.
One of the most popular methods of combating rising damp is by using a course of damp-proof injections, which is a solution that is both practical and effective. Most important, it causes minimal disruption to the occupants of the building being treated.
Building materials such as brick and stone, mortar and concreate are all regarded as porous meaning that they will allow moisture to enter inside of the building unless blocked by a barrier such as a cavity. But now there is an effective method of preventing the moisture absorption, while at the same time allowing the existing moisture in a wall to evaporate into the air.
By externally applying a solvent-based Silicone Resin solution to surfaces such as masonry, this can be an effective measure in protecting your walls from penetrating damp. The fluid is a high-performance water repellent which will not allow water passage but will allow free movement of vapour from within the wall.
INTERNAL DAMP WATERPROOFING BELOW GROUND – CAVITY DRAINAGE MEMBRANES
Structural waterproofing is designed to stem the flow of water from whatever source, creating what can best be described as a room within a room. A damp-proof membrane (sheet materials made of High-Density Polythene) which has raised studs.
The cavity created by the membrane is known as an air gap or in wet conditions acts as a cavity drainage system. Special fixings secure the membrane to the substrate and also provide the fixing for a dry lining or plasterboard system.
Cavity drainage membranes also may be used on the floor, where usually no fixing is required, and they may be screeded over or overlaid with a floating timber floor. When it is known or suspected that water will penetrate behind the membrane, drainage channels, sumps and pumps can be incorporated into the design. A plaster membrane with fibreglass mesh reinforcement over its front face to facilitate plastering directly is also available. This sealed system can be installed quickly and effectively, creating a warm, dry area with a high-grade internal finish.
SOLID FLOOR MEMBRANES
Solid floors, whether stone or concrete, will allow moisture penetration through to the surface if not protected by an impervious membrane or by a waterproofing solution incorporated in the construction of the floor. However, a quick and effective solution rather than breaking up and removing the affected floor can be to lay a surface damp proof membrane.
This membrane is a two coat, fast curing, two-part epoxy-based damp proof membrane and moisture suppressant system for concrete and cement/ sand screeds.
"I should like to take this opportunity to thank you for the respect and courtesy shown by your workforce. The manner in which they conducted their business was exceptional. The house was immaculate when they left, there was no dust or rubbish lying about. The front street was swept and washed clean. Thank you once again for a lovely neat job.
