Damp and Timber Survey – Warrington
Our client engaged Damp Solutions UK to carry out a comprehensive damp and timber survey on a mid-terrace property they were interested in purchasing in Warrington.
A highly reputable regional building contractor specialising in large-scale residential projects needed us to waterproof their Victorian residential extension in Manchester.
Damp Solutions UK was engaged by a well-established regional building contractor to carry out a comprehensive basement waterproofing solution for a prominent Victorian property located on a sloped site. The property was undergoing an extensive residential extension, transforming the existing basement at the front and extending it to the rear. Given the historical nature of the Victorian building and the sloped terrain, careful planning and technical expertise were required to ensure effective waterproofing and long-term durability.
– The basement was existing at the front of the property, with an extension to the rear on a sloped site.
– External waterproofing was not a viable option for the front basement due to site constraints and the presence of valuable landscaping.
– The Victorian construction posed additional considerations around heritage preservation and internal access.
Recognising the complexity of the project and the need for an expert solution, the reputable building contractor approached Damp Solutions UK, leveraging our extensive knowledge and experience within the basement waterproofing sector.
Our team conducted a thorough site assessment, considering the existing construction, site conditions, and project requirements. To deliver a reliable waterproofing solution without external membrane installation, we designed a bespoke Type C internal waterproofing system.
The Type C basement waterproofing system, also known as a structural waterproofing method, is a comprehensive solution designed to permanently prevent water ingress into below-ground structures. It is suitable for buildings where internal water management is required due to external constraints or inherent structural challenges. This case study provides an overview of the system’s components, applications, installation procedures, advantages, and considerations.
The Type C waterproofing system involves the application of a durable, flexible membrane directly to the internal face of the basement walls and floors. This membrane acts as a barrier, preventing water penetration from the ground and surrounding soil. It is typically combined with internal drainage solutions such as channels and sump pumps to manage and divert any water out of the basement.
Components of the Type C System:
1. Internal Membrane
– Usually a multi-layer, flexible, chemical-resistant membrane applied to the interior surfaces of basement walls and floors.
– Materials used include polymer-modified bitumen, liquid-applied waterproof coatings, or sheet membranes like polypropylene or rubberized membranes.
2. Drainage Channels
– Internal channels or drainage installed to collect any water that infiltrates the membrane.
– These channels direct water towards sump pumps for removal.
3. Sump Pump System
– Submersible pumps, single or double with alarms and battery backup to remove any water ingress that infiltrates behind our system.
At Damp Solutions UK, we pride ourselves on delivering tailored waterproofing solutions that respect the unique challenges of each property while ensuring long-term protection and peace of mind. This Victorian basement project demonstrates our ability to combine technical expertise, careful planning, and specialist installation to achieve a watertight, durable result where external options were not possible.
If you’re facing a complex basement or below-ground waterproofing challenge, trust our experienced team to design and install a solution that safeguards your property for years to come.

Our client engaged Damp Solutions UK to carry out a comprehensive damp and timber survey on a mid-terrace property they were interested in purchasing in Warrington.
In November 2025, a comprehensive damp and timber survey was conducted on a two-bedroom red brick terraced property located in Preston. The objective of this survey was to identify potential moisture-related issues, assess the condition of the timber within the structure, and recommend appropriate remedial actions.
The Warrington homeowner reported persistent damp on ground-floor internal walls (tide marks, flaking paint/plaster) and noticeable movement in the timber floor. Damp Solutions UK was instructed to carry out a full survey and recommend remedial works.
