Basement Waterproofing & Cellar Tanking

Do you have an unused basement beneath your home that could be turned into a living room, playroom or even a wine cellar? Perhaps you’ve already decorated the space and found it’s now taking in water?

Any structure below ground level can suffer from lateral penetration of water. Moisture in the surrounding soil and the resultant hydrostatic pressure forces water through any tiny crack or gap in the brickwork. This ingress causes the basement area to become damp - which can cause mould and structural damage – making the area unusable.

London & Home Counties carries out basement waterproofing in properties across the Capital and into Essex, enabling you to protect your home or business premises from damp - while providing extra space without having to move or build an extension.

What Is Basement Tanking?

The materials used to build your property are not naturally waterproof and will let in moisture when in constant direct contact with it. Without cellar tanking, moisture from the surrounding soil will be drawn into the brickwork or concrete, and emerge on the interior of the wall before evaporating.

This causes the walls to feel damp, and the overall humidity levels inside the basement to rise. When we tank the basement of a property we use either a cementitious or cavity membrane system, to create a waterproof barrier that prevents this ingress of water. 

Prevention Measures

Before you call us to arrange a survey, make sure you have eliminated all obvious drainage problems first. 

Keep your gutters clear, and make sure downspouts are discharging directly into a drain or well away from the house. Ideally the ground level should slope away from your property to encourage water to drain away from the basement.

If your basement is still damp after taking these preventative measures, it’s time to call the professionals.
