What Does Tanking Mean In Building?
Tanking is a term used to describe the application of a waterproofing barrier to the walls, base slab, and sometimes roof of a below-grade structure.
This barrier is designed to protect the structure from water penetration caused by hydrostatic pressure building up outside the retaining walls.
The two main methods of tanking are using a membrane or coating, such as mastic asphalt, proprietary adhesive DPM, bitumen, asphalt, resin/tar, and tanking slurry.
Tanking membranes consist of a studded or dimpled plastic sheet which is fixed onto the internal face of masonry, block or rendered walls and sealed with tape.
Tanking coatings are typically used for larger areas and can be applied with a brush before being overcoated with a breathable render.
Support must be provided completely to both sides of tanking membranes in order to create an effective seal.
Tanking should be provided wherever a floor level is below ground level in order to prevent water ingress into the structure.
What Is The Difference Between Tanking And Waterproofing?
The difference between tanking and waterproofing is that tanking involves the application of a membrane or coating to the inside or outside of a structure to stop water from entering the habitable space, while waterproofing is a general term for all forms of waterproofing that can be used to keep a basement or cellar dry, manage water seeping into the property, and move it away.
Tanking provides physical barrier protection against water entering the building, while waterproofing membranes are often used for high-risk projects such as luxury apartments.
Waterproof concrete may also be used in some cases. In addition, a combination of tanking and waterproofing may be used for maximum protection.
How Do You Do Tanking?
Tanking is a method of waterproofing walls and floors by creating an impermeable barrier to prevent water ingress.
There are three main methods for tanking wet walls: liquid bitumen coatings, cement-based slurry, and air gap membranes.
Cementitious tanking slurry is a powder that must be mixed with water before application.
It should be applied in the proper direction following manufacturer’s instructions and should be at least 3mm thick.
Tanking membranes are also available and can be installed on walls or floors.
When using tanking liquids or membranes, it is important to check for any water seepage coming through the wall or any history of flood damage.
What Are The Benefits Of Tanking?
The process of tanking a building involves applying a waterproof membrane or coating to the inside or outside of the structure in order to prevent water from entering the habitable space. This can be done during construction or on an existing structure.
Tanking a building offers several benefits, including reducing energy costs by sealing the foundation, creating a dry, mould and mildew free space inside the home, and providing a physical barrier between the ground and outer layer of masonry to prevent moisture from entering.
Additionally, tanking can help protect against flooding and other water damage.
