Basement Waterproofing in Essex
Transform your damp basement or cellar into dry, usable space. We provide professional waterproofing solutions with long-term guarantees.
Why Basements Get Damp
Basements and cellars are inherently challenging environments. Being below ground level, they're surrounded by soil that holds water, creating constant pressure trying to push moisture through walls and floors.
Many older basements were never designed to be waterproof - they were built for storage, not habitation. Converting them into usable living space requires comprehensive waterproofing to manage the inevitable water pressure.
Common Basement Damp Issues
- Water seeping through walls or floor
- Damp patches, especially after rain
- Efflorescence (white salt deposits)
- Musty smell and high humidity
- Visible water ingress or flooding
- Mould growth on walls and stored items
Basement waterproofing creates a dry, protected space below ground
Waterproofing Solutions
We offer different waterproofing systems to suit your basement and intended use.
Cementitious Tanking
A waterproof render or slurry applied directly to walls and floors, creating a barrier that prevents water entry. Best suited for light water pressure and where maximum floor area is needed.
- • Applied directly to substrate
- • Maximises usable space
- • Can be painted or tiled over
- • Suitable for low-medium water pressure
From £80-£120 per m²
Cavity Drain System
A studded membrane is fixed to walls and floors, creating a cavity that allows water to drain to a sump chamber where it's pumped away. Ideal for higher water pressure situations.
- • Manages water rather than blocking it
- • Handles high water pressure
- • Reliable long-term solution
- • Suitable for habitable conversions
From £150-£250 per m²

Basement Waterproofing FAQs
What causes basement damp?
Basements are below ground level and surrounded by soil, making them vulnerable to groundwater pressure (hydrostatic pressure), lateral water penetration through walls, and condensation due to cooler temperatures. Water can enter through walls, floors, and the junction between them.
What is the difference between tanking and cavity drain?
Tanking creates a waterproof barrier on the inside of walls/floors to prevent water entry. Cavity drain systems accept that water will enter but manage it via a membrane and drainage channel that directs water to a sump pump. Both are effective but suit different situations.
How much does basement waterproofing cost?
Costs vary significantly based on basement size and the chosen system. Simple tanking of a small cellar might cost £3,000-£5,000, while comprehensive cavity drain systems for larger basements typically cost £5,000-£15,000 or more. We provide detailed quotes after survey.
Can I convert my basement into living space?
Yes, with proper waterproofing a basement can become a comfortable, habitable room. This may require building regulations approval. We can advise on the requirements and waterproofing needed for your specific conversion project.
