What are the different types of waterproofing for basements?

Waterproofing your basement is essential for protecting your home from moisture, mould, and potential structural damage. Whether you’re planning a new build or renovating an existing property, choosing the right waterproofing method can make all the difference in keeping your basement dry. But what are the different types of waterproofing available?

1. External Waterproofing

Also known as positive-side waterproofing, this method involves applying a waterproof membrane or coating to the exterior walls of the basement. It’s often considered one of the most effective ways to keep water out, as it prevents moisture from entering the building altogether.

  • How it works: A waterproof membrane or barrier is applied to the foundation walls before backfilling the soil around the basement. This creates a protective layer that prevents water from seeping in.
  • Longevity: External waterproofing typically lasts the longest because it tackles the root of the issue by stopping water at the source.

2. Internal Waterproofing

If external waterproofing isn’t possible, internal waterproofing can be a good alternative. This method, also known as negative-side waterproofing, works by managing water that has already penetrated the basement walls.

  • How it works: Internal sealants are applied to the inside walls of the basement to block moisture from entering the living space. Sometimes, additional drainage systems are installed to help divert water away.
  • Longevity: While it can be an effective solution, internal waterproofing doesn’t address the source of the water, meaning it may not last as long as external methods without regular maintenance.

3. Drainage Systems

Another popular option is installing a basement drainage system, such as a French drain or a sump pump, to control and manage water that enters the basement.

  • How it works: A French drain is installed around the perimeter of the basement to collect and redirect water away from the foundation. A sump pump can also be used to pump water out of the basement and away from the property.
  • Longevity: With proper maintenance, drainage systems can last for many years, making them an effective solution for managing water in basements that are prone to flooding or dampness.

4. Cavity Drain Membrane Systems

Cavity drain systems are an innovative approach to waterproofing that involves installing a drainage membrane on the inside of the basement walls.

  • How it works: A plastic membrane with studs creates an air gap between the basement walls and the membrane itself. Water can then flow freely into drainage channels and is either pumped out or drained away from the property.
  • Longevity: This system is highly durable and requires minimal maintenance, making it a popular choice for modern waterproofing solutions.

Choosing the Right Waterproofing Method

Selecting the right waterproofing method depends on various factors, including the type of basement, the surrounding soil, and the level of water exposure.
