A wet, damp, or leaking basement is one of the most significant moisture problems a property can face. Whether you have a traditional stone cellar prone to seasonal flooding, a below-ground space with persistent water ingress, or you are looking to convert an existing basement into usable habitable space, effective waterproofing is essential.
Basement waterproofing is a specialist discipline that requires careful diagnosis and the selection of an appropriate system for the specific conditions present. The wrong approach - such as applying render over an active water source without addressing the cause - will fail. We begin every project with a detailed assessment of the construction, hydrostatic pressure, drainage, and intended use before specifying anything.
Our team has extensive experience with all major basement waterproofing systems across Lincolnshire and the East Midlands, from Victorian cellars in townhouses through to modern basement extensions. We provide free quotations and a clear, transparent specification so you know exactly what is involved before any work begins.
The British Standard BS 8102 defines three types of basement waterproofing protection. Understanding which is appropriate for your property is essential to achieving a lasting result:
Many projects benefit from a combination of system types. Our surveyors will assess your specific conditions and provide a reasoned recommendation for the most appropriate and cost-effective solution.
From initial assessment through to guaranteed completion, every basement waterproofing project follows our structured process.
We begin with a thorough inspection of your basement, assessing the construction type, the nature and severity of water ingress, ground water conditions, drainage, and the intended use of the space. We identify any structural issues that need to be addressed before waterproofing and document our findings fully.
Based on the survey, we specify the most appropriate waterproofing system for your basement, referencing BS 8102 guidance. We explain the options clearly, including the reasoning behind our recommendation, and provide a detailed, itemised quotation before any commitment is required from you.
Our trained operatives install the specified system to manufacturer's standards, ensuring full coverage, correct detailing at junctions and penetrations, and proper drainage provision where applicable. All associated trades such as sump pump installation, drainage channels, and service penetration sealing are co-ordinated and completed as part of the works.
On completion, we hand over full documentation including the system specification, installation records, and your 20-year guarantee. We provide guidance on maintenance requirements - for example, annual sump pump testing - and remain available to assist with any questions following completion.

In most cases, yes. The method and extent of works required will depend on the construction type, the severity of water ingress, the depth below ground, and the intended use of the space. Our surveyors will assess your basement thoroughly and recommend the most appropriate and cost-effective solution for your specific situation.
See the answer on our basement waterproofing page.
Yes, we work across residential and commercial properties of all types and sizes - from Victorian cellars and terraced house basements through to commercial premises and listed buildings requiring specialist approaches. We have extensive experience with the full range of below-ground waterproofing challenges.
A basement conversion is priced around the size of the space, its condition, the waterproofing system needed and the finish you want, so costs vary widely from tens of thousands of pounds upwards. The waterproofing design is the critical part and has to suit the structure, which is why we survey below ground first and set out a clear, itemised specification before giving you a price. All waterproofing is covered by our 20 year guarantee.
Most cellars can be converted into dry, usable rooms, but the right approach depends on head height, the construction, how much water is present and how you want to use the space. The key is a waterproofing system designed for the structure, usually a cavity drain membrane taken to a sump and pump. We assess all of this at survey and tell you honestly what is achievable before any work is planned.
