![]() To tank a wall, there are two common tanking methods available depending on your needs.Ĭementitious tanking slurry - a paint-like substance that has been chemically engineered to form a protective barrier when applied to internal walls. This means that moisture, water pressure and ingress are serious considerations. More often than not, walls below ground like basements, cellars and sunken garages are surrounded by earth. The term “tanking” comes from the idea that by completely sealing a room, a waterproof tank-like barrier is created. When we refer to tanking walls, it's usually in reference to below ground structures like basements or as a precautionary measure on damp walls above ground. Wall tanking or “tanking” is a method of preventing water ingress by creating a completely impermeable waterproof barrier on an internal wall. ![]() When the water evaporates through the wall surface, white salt crystals can be seen in small deposits on the wall that can look like tide marksįind out more about spotting and treating rising damp. However, if there is no DPC or it has failed then moisture from the ground can rise up through the wall via a process called capillary action. Ordinarily, a physical or chemical damp proof course (DPC) exists to prevent this. Walls made of stone and brick are porous which means that they can absorb moisture sitting either underneath or by the side of them. Tanking is a reliable way of dealing with the effects of penetrating damp once the root cause has been fixed.Īlthough rising damp can’t be solved by tanking, it’s worth giving you a quick overview and telling you where to find more information to rule it out. In the UK, it is quite a common problem as we have a perfect storm of wet weather and old buildings that may have damaged outer walls. With water coming through to the inside of your property, you may see localised spots of black mould, paint blistering and damp patches - these are the common signs that you may be dealing with penetrating damp. Blocked gutters and plumbing issues can also result in penetrating damp. It may be that there is a crack in some brickwork/render. Walls can become wet because they are structurally compromised, where a building fault is allowing water to enter and pass through. This occurs due to hydrostatic pressure being exerted on the earth-retaining walls. Below ground, you may experience damp walls due to water ingress. Damp in walls is commonly caused by penetrating damp and in some rare occasions rising damp. It also damages decoration, and looks and smells bad. ![]() They can lead to structural issues as well as causing health issues. The walls of a building can become damp for many reasons: building faults, penetrating damp, plumbing issues, and rising damp. We take you through the tanking methods available and the products you will need along with our usual no-nonsense advice. If you want to take steps to protect against this or deal with existing damp walls then you should consider wall tanking. This means you are open to a whole load of potential problems. The internal walls of a property are vulnerable to water ingress and damp.
