Commercial Waterproofing Specialists
Advanced Damp are commercial waterproofing specialists delivering compliant, risk-led waterproofing solutions across the UK. We work on complex commercial, mixed-use and below-ground projects where failure risk, sequencing and long-term performance matter. Our role goes beyond installation: we support clients from early-stage assessment and design coordination through to delivery, quality assurance and sign-off.

Commercial Waterproofing for Demanding Environments
Commercial buildings face fundamentally different waterproofing risks compared to domestic projects. Higher water tables, complex interfaces, structural movement, service penetrations and long-term maintainability all increase the consequences of failure.
We deliver commercial waterproofing solutions for:
- Basements and below-ground structures
- Commercial and mixed-use developments
- Healthcare, education and public-sector buildings
- Industrial, retail and logistics facilities
- Refurbishment and change-of-use projects
Our approach is based on risk reduction, compliance and buildability, not generic product-led fixes.
Our Commercial Waterproofing Process
Every project follows a clear, auditable process designed to minimise failure risk.
Technical Review & Risk Assessment
We assess site conditions, ground risks, structural form and intended use to identify waterproofing vulnerabilities early.
System Strategy & Recommendations
Based on the risk profile, we recommend appropriate structural waterproofing systems, detailing how they interface with structure, drainage and finishes.
Delivery & Sequencing Support
We coordinate installation sequencing and interface management to avoid common construction-stage failures.
Quality Assurance & Sign-Off
Inspections, photographic records and sign-off procedures ensure the system aligns with specification and performance intent.
Our Standards, Compliance & Best Practice
Our commercial waterproofing work aligns with BS 8102:2022, the code of practice for protection of below-ground structures against water ingress, covering Type A barrier, Type B structurally integral and Type C drained protection. We place particular emphasis on:
- Risk-based waterproofing selection
- Interface detailing and sequencing
- Maintainability and access requirements
- Clear allocation of responsibilities
This structured approach is essential on commercial projects where remediation costs and operational disruption are high. Our surveys and designs are produced by CSSW-trained specialists, and we install as Newton Waterproofing certified contractors.
Typical Waterproofing Failures We Prevent
Many commercial waterproofing issues arise not from product failure, but from poor coordination and detailing. We commonly prevent issues such as:
- Inadequate interface detailing between systems
- Incorrect sequencing leading to compromised membranes
- Unmanaged service penetrations and fixings
- Drainage dependency without a maintenance strategy
- Mismatch between design intent and site delivery
By addressing these risks early, we reduce the likelihood of repeat defects and long-term liability.
Who We Work With
Our commercial waterproofing services are structured for professional teams. We integrate with project teams to reduce technical uncertainty and prevent downstream defects.
Specialist Commercial Services
Our commercial waterproofing expertise covers basement and below-ground waterproofing, structural systems, new-build and refurbishment projects, water ingress risk mitigation and design-stage support.
Why Choose Advanced Damp for Commercial Waterproofing
We take a commercial-first, technically grounded approach, shaped by extensive experience working on high-risk and complex structures. Our team has a strong understanding of construction sequencing and critical interfaces, ensuring that waterproofing solutions integrate seamlessly with the wider build programme.
We place a high priority on clear, practical communication with both design and construction teams, so intent, responsibility and execution remain aligned throughout the project. Above all, our focus is on long-term performance rather than short-term fixes, delivering systems that continue to protect the structure well beyond practical completion. Our role is to reduce risk, not introduce uncertainty.
Commercial Waterproofing FAQs
Questions we hear most from design and construction teams.
At what project stage should waterproofing be considered?
As early as possible, ideally RIBA stages 2 to 3. Waterproofing strategy affects structural form, drainage, sequencing and buildability, and the cost of correcting a waterproofing decision rises sharply once concrete is poured. Most of the remedial work we carry out traces back to waterproofing being treated as a product choice late in design rather than a strategy set early.
Do you work to BS 8102?
Yes. Our below-ground waterproofing design and installation aligns with BS 8102:2022, the code of practice for protection of below-ground structures against water ingress. That covers risk-based system selection across Type A barrier, Type B structurally integral and Type C drained protection, including combined protection where the required internal grade demands it.
Can you take responsibility for waterproofing design as well as installation?
Yes, and on commercial projects we recommend it. Split responsibility between designer, supplier and installer is one of the most common root causes of waterproofing failure and disputed liability. We provide design input, install with our own trained technicians, and document the works through inspections, photographic records and sign-off, so responsibility sits in one place.
Do you handle remedial work on failed systems installed by others?
Yes. We investigate why the existing system failed before specifying anything, using moisture profiling, thermal imaging and targeted testing where needed. Common findings include interface detailing failures, compromised membranes from incorrect sequencing, unmanaged service penetrations and drainage that was never given a maintenance strategy. The remedial specification addresses the cause, not just the symptom.
Which sectors and building types do you cover?
Commercial and mixed-use developments, healthcare, education and public-sector buildings, industrial, retail and logistics facilities, and refurbishment or change-of-use projects. We work with architects, developers, main contractors, managing agents and estates teams across London and the South East, with coverage into the Home Counties and Midlands.
