What is Cellar Tanking?

Definition and Importance of Cellar Tanking

Cellar tanking refers to the process of waterproofing or damp-proofing a cellar or basement. Tanking a cellar (also known as basement tanking) requires the application of a waterproof cement or ‘tanking slurry’ to the walls and floor of a building’s cellar. The term ‘tanking’ refers to creating a ‘tank-like’ waterproof seal around the cellar or basement.

Tanking cellar walls and cellar floor is the most effective way to ensure total cellar waterproofing. Employing the help of a professional to treat damp walls, completely waterproof your cellar and create a useable space will have countless benefits.

Benefits of Waterproofing a Cellar

  • Prevents structural damage. Damp such as rising damp and penetrating damp, can cause serious damage to the structure of a building. In the log run, this can cost a lot in repairs.
  • Reduces risk of health issues. The perfect breeding ground for mould spores, damp can cause respiratory issues, infections and issues with the immune system.
  • Increases property value. Buyers will have peace of mind knowing that a potential property purchase is properly waterproofed.
  • Protects against water damage. Even before it gets to structural damage, damp can cause damage to decor, masonry surfaces, ground areas and much more.
  • Prevents mould and mildew growth. Tanking a cellar, or any waterproofing system, will reduce the chances of damp dramatically and therefore the chances of any mould or mildew growth.
  • Reduces energy bills. Cellar tanking will create not only a waterproof barrier, but also draft proof your underground level making your basement level economical to heat.
  • Creates a healthier living environment. The Cellar Tanking leaves a clean, damp free living space.
  • Increases usable space with a cellar conversion. Increasing the usable space will often add value to your property too!

Why Waterproof a Cellar?

Common Issues with Damp Cellars

Walls and floors in cellars are often subject to lateral damp penetration. This can result in a damp, unusable space that may lead to structural damage.

Consequences of Not Waterproofing a Cellar

As well as walls and floors becoming damaged, health issues can arise from damp conditions, property value can decrease, water damage can occur and mould and mildew can grow.

Preparing Cellar Walls for Tanking

Checking for Seepage and Water Damage

A professional will always check for any active water ingress before proceeding with the process. If there is water ingress (water is actively entering the cellar) they will always address the issue before applying the tanking slurry. Porous cellar walls can be treated with a damp proof membrane, also known as tanking membrane which goes a long way to making your cellar waterproof.

Creating a Wall Floor Junction or Fillet Joint

The wall-floor or fillet joint is a critical part of basement tanking. It’s a common point of water ingress, so it must be treated with special care during the process.

Common Issues with Damp Cellars

How Does a Professional Tank a Cellar?

Mixing the Tanking Slurry

Mixing the tanking slurry involves gradually adding the slurry powder to clean water while mixing until a smooth, lump-free consistency is achieved.

Applying the Tanking Slurry to Cellar Walls and Floors

Once the tanking slurry is properly mixed to the correct consistency, it is applied to the prepared cellar walls using a brush or roller.

Tanking requires two coats. Once the first layer of tanking slurry cures, a second coat is applied. Tanking slurry blocks water ingress and seals the walls so this application process must be done correctly in order to guarantee the tanking systems efficiency.

Alternative Waterproofing Methods

Cavity Drainage System

  • A cavity drain system is a type of basement waterproofing that uses a studded cavity drain membrane on the damp walls and floor of the basement or cellar.
  • Water entering the basement is controlled by the cavity drain membrane and directed to a cavity drainage system that runs around the perimeter of the floor.

Exterior or External Waterproofing

Exterior waterproofing involves applying a waterproof coating or membrane to the outside of the foundation walls.

This is typically done during the construction of the house but can be done later if necessary.

Interior Drainage Systems

Interior drainage systems are installed inside the cellar or basement and collect water from where the floor and wall meet (wall floor joint). A channel is installed at the base of the walls, running around the perimeter of the floor.

Sump Pumps

A sump pump is a device that moves water from your basement to the outside of your home. A sump is a naturally constructed pit, usually a hole carved below the main surface of your basement floor. This pit, known as a basin, holds the sump pump.
