How To Waterproof A Basement

Waterproofing your cellar or basement offers multiple approaches. With various systems, products, and manufacturers available, our surveyor will delve into your needs and offer a tailored solution. Our goal? Ensuring you attain the desired outcome: a dry, functional space that not only meets but elevates the value of your home.


Following BS8102: 2022

When a wall sits partially or entirely underground, it acts as a support for the soil. Moisture from the surrounding earth tends to seep into your basement through this wall. In retrofitted basements, the wall-floor joint is often the primary area prone to issues. The BS 8102 2022 serves as the guideline for safeguarding below-ground structures against water penetration. At DAMPX, we strictly adhere to this British Standard in implementing basement waterproofing solutions.

Type A, B & C systems

Usually, basement waterproofing systems fall into three categories: Type A (Barrier protection), Type B (Structurally integral protection), and Type C (Drained protection). Choosing the right system is crucial to create the desired environment. In high-risk scenarios, a combined protection approach might be necessary. Each system has its own advantages and drawbacks, just like many other things in life. Our surveyors will have a chat with you, discuss your needs, and suggest the best protection method for your situation.

Planning & Building control

Depending on what you would like to do with your basement, you might need to go through planning and building control processes. Usually, if your basement doesn’t involve adding new windows, door openings, or exterior access, planning permission might not be necessary since it’s below ground. However, if you’re converting it for regular use, you’ll likely need building control approval. For further details, you can check out

What is Basement Waterproofing?

Basement waterproofing involves specialised methods to keep water out of homes and buildings. It becomes necessary when a structure is built below ground level or when external ground levels meet internal floor levels (Level Access).

This protection is crucial to guard against groundwater that exerts pressure on earth retaining structures, known as hydrostatic pressure. If left unchecked, hydrostatic pressure can lead to water seepage and dampness within the below-ground structure at some point during the building’s life. In severe instances, it might even result in flooding.


Methods of Waterproofing 

Interior Waterproofing: This method involves managing water that has already penetrated the basement by using interior drainage systems, sump pumps, and sealants to redirect and manage the water away from the interior space.

Exterior Waterproofing: Exterior waterproofing focuses on preventing water from reaching the foundation walls by applying waterproof membranes, coatings, and drainage systems on the exterior surfaces of the basement walls.

Crack Repair: Identifying and repairing cracks in the basement walls or floors is crucial in preventing water seepage. Sealants and specialized materials are used to fix these vulnerabilities.
