Do I need to tank a retaining wall?

Retaining walls also need waterproofing treatments to reduce the build-up of hydrostatic pressure on the wall and to protect it from ground dampness. Water in the wall can create a host of problems including corroding steel supporting rods, which can then expand and crack the concrete.

How do you structure a retaining wall?

A retaining wall is a structure that holds or retains soil behind it. There are many types of materials that can be used to create retaining walls like concrete blocks, poured concrete, treated timbers, rocks or boulders. Some are easy to use, others have a shorter life span, but all can retain soil.

What is involved in tanking a wall?

Tanking walls will prevent damp problems by forming an impermeable waterproof barrier. The barrier is formed using tanking slurry that is applied directly to the wall. Tanking Slurry is simple to apply and is ideal for coating foundation walls below-ground level.

Does tanking require building regulations?

The Building Regulations stipulate that tanking must be applied to all new build structures below ground, but tanking can also be applied to existing buildings, to prevent water penetration into basements and cellars, as well as helping to tackle rising damp.

How deep should a footing be for a retaining wall?

The general rule of thumb is to bury about one-eighth of the height of the wall. For example, if your wall will be three feet (36 inches) tall, the first course of blocks should start five inches below soil level. The gravel base should start three inches below this.

Is Tanking the same as damp proofing?

Tanking is effectively a liquid coating that bonds to damp masonry and then cures to form a waterproof barrier. This project deals with tanking wet or damp walls and keeping water and moisture at bay to prevent it from damaging inner surfaces.

Do you have to put drainage behind a retaining wall?

Every retaining wall should include drainage stone behind the wall. Though it is a good idea to install a drainage pipe on all walls, there are certain situations where a perforated drain pipe is absolutely necessary.
