In addition, PermaSEAL Tanking Slurry contains an acrylic polymer that improves strength, bonding and abrasion resistance. After hardening, PermaSEAL tanking becomes a vapour permeable and watertight coating capable of withstanding water pressure. Tanking Slurry Uses For maximum effectiveness, it is essential that the applied layers of Vandex BB75 are kept damp for at least 5 days and protected against evaporation by sun and wind. Careful post-watering should be carried out at intervals, starting from the day following the application. Alternatively, the surfaces can be covered with plastic sheeting, wet mats or moist sand. The use of curing compounds is not recommended. When it comes to below ground, it often pays to stop the water before it enters the building. Cementitious tanking slurries are a very successful way to achieve this and effectively tank a basement. Not every waterproofing situation below ground requires a cavity drain membrane. Many european countries do not use cavity drain membranes and rely on cementitious systems. Though tanking slurry cannot treat rising damp (you’ll need a special damp proofing course for this), it is a highly effective method of preventing penetrating damp.

Tanking slurry can be used on a damp wall above ground to stop the passage of water. Ideally, you will want to identify and resolve the source of damp before applying it.In addition, PermaSEAL Tanking Slurrycontains an acrylic polymer that imparts improved strength, bonding and abrasion resistance. After hardening, PermaSEAL tanking becomes a vapour permeable and watertight coating capable of withstanding water pressure. Tanking Slurry Uses

Some areas of the wall may also take longer to dry than others, and you may notice some sweating. This is caused by condensation on the cold surface and is normal during the curing process. Tanking slurry at Build & Plumb Wear protective overalls and a mask as the chemical compounds in cementitious slurry can be harmful to eyes and skin. Vandex BB White is a version of Vandex BB75 based on white Portland cement. Its characteristic white colour makes it particularly suitable for use on exposed surfaces, e.g. potable water reservoirs. Vandex BB75 Z However, walls below ground are often subject to hydrostatic water pressure and any flaw in the application of cementitious tanking can have serious consequences. Type C cavity drainage systems should be a consideration.More often than not, walls below ground like basements, cellars and sunken garages are surrounded by earth. This means that moisture, water pressure and ingress are serious considerations. How do you tank a wall?
