Structural Waterproofing

Structural waterproofing encompasses a range of techniques and measures aimed at safeguarding buildings and structures from water infiltration, ensuring their lasting strength and resilience. This involves the utilization of diverse waterproofing systems and materials to create a protective barrier that effectively blocks water from seeping into crucial structural components like foundations, basements, walls, and roofs. By employing structural waterproofing, not only is the building shielded from water-related damage, but it also mitigates problems like dampness, mold growth, and structural decay.

What You Should Know about Structural Waterproofing

We offer the highest quality of service for those seeking a basement or structural waterproofing solution. From taking design responsibility from our approved supplier to installation by our own experienced teams and approved installers.

    Waterproofing Across Multiple Structures and Elements

    Comprehensive approach: Structural waterproofing requires a comprehensive approach that considers various elements such as foundations, basements, walls, roofs, and below-ground structures. Each of these areas may have different requirements and challenges that need to be addressed with appropriate waterproofing systems.

      Structural Integrity

      One of the primary reasons for its importance lies in protecting the integrity of the building’s foundation and structural elements. Water seepage can compromise the foundation, leading to structural instability and costly repairs. By implementing effective waterproofing measures, such as barrier systems or drainage solutions, we create a robust defense against moisture, preventing its infiltration into critical areas like basements and walls.

      Solutions for Long-term Protection

      Waterproofing makes up roughly 1% percent of the total cost of building construction, but accounts for up to 80% of construction repairs and litigation! We exist to deliver a quality installation and give you peace of mind

            Basement Conversions

            Basement conversions have gained increasing popularity in recent years as a practical and cost-effective way to maximize space in urban areas. By transforming dark and underutilized basements into functional living areas, homeowners can significantly increase the overall value and functionality of their properties. These conversions offer a myriad of possibilities, ranging from creating extra bedrooms, home offices, or entertainment rooms to adding gyms, home theaters, or guest suites.


            One of the primary advantages of basement conversions is that they often require less extensive construction compared to building additional stories or extensions. This makes them a more environmentally friendly choice and can reduce the time and disruption associated with traditional home expansion projects. Additionally, basement conversions allow homeowners to maintain the overall architectural integrity of their property, as the changes are mostly concealed underground.

            Why Convert Your Basement?

            Converting your basement can be a highly beneficial decision for several compelling reasons. First and foremost, it offers a remarkable opportunity to expand your living space without the need for major structural changes.

            Cost effective, budget-friendly than building additional stories or extensions

            Utilising existing space reduces the environmental impact associated with new construction

            Basements can be transformed into various functional spaces, such as home offices, gyms or storage areas

            Since most changes occur underground, the exterior appearance of your property remains largely unaffected

            A well-executed basement conversion can significantly raise your property's market value

            Water Proofing A Basement

            If you are looking to convert a basement at your property, the first step would be to waterproof the basement, this will ensure that it would become dry and safe for general use. Very often, basements reside down below something called a water table, causing them to be vulnerable, leading to cracks in the walls and leaks, inevitably ending in damp problems.

            The Benefits

            Converting your basement provides a cost-effective, environmentally conscious, and architecturally harmonious way to expand your living area. Its versatility, coupled with the potential for a higher property value, makes it an attractive option for homeowners seeking to maximize their home’s potential without the complexities of building up.

            • Warranty of the system performance is provided at completion.

            How We Do It

            Tanking is applying a physical barrier to a basement wall, this process will prevent moisture from ingressing into the walls. Our preventive barrier consists of waterproof slurry, or cement, blocking any water from getting into your basement. We also use drain membranes, which is robust and durable and can be applied to floors, walls etc. 

            During the application process, we pay close attention to critical areas prone to potential water entry, such as joints, corners, and pipe penetrations, reinforcing them with precision to prevent any weak points. To guarantee the highest level of quality, we conduct comprehensive inspections at every stage of the waterproofing process, assuring that each step is executed to perfection.

            High Drainage Capacity

            Baseline 20 cavity drain membrane is moulded from high density polyethylene (HDPE) and incorporates integral 20mm stand-off studs at 50mm centres to offer excep­ti­onally high drainage capacity.­ Our air-gap membranes are robust and durable.­  They can be used on floors, walls, vaulted soffits and tunnels in basement water­pro­ofing and other construction and civil engineering appli­cations that require a cavity drain system to combat water seepage.

            Ground Gas/Radon Mitigation in Basements


            BRE Guidance 343 – Guide to Remedial Measures in Existing Dwellings, identifies the following methods of reducing the amount of radon entering the basement:

            • Sealing floors and walls
            • Increasing underfloor ventilation
            • Improving ventilation to the basement area
            • Installing a Radon Sump
            • Introducing positive pressure ventilation to the property
            • Improving ventilation to the property

            In areas where Radon levels are considerably low, then an appropriately installed waterproofing system would generally suffice. However, in areas with high Radon levels, then the installation of a cavity drain system along with a Radon Sump and/or Positive Pressure Fan would be appropriate. It is always recommended to monitor the basement Radon levels after installation to ensure the installed measures are more than adequate.

            For new build Radon protection in a basement, BRE211 states;
            “If a basement cellar is to be tanked with an impervious barrier to prevent damp penetration, the tanking will also provide Radon protection.

            How It Enters Our Home

            Radon gas can enter homes through several pathways, primarily as a result of its natural occurrence in the soil and rocks beneath the building. The main mechanisms through which radon enters homes are:

            • Soil penetration
            • Crawlspace entry
            • Foundation cracks
            • Well water
            • Building materials
            • Air exchange

            Essential Radon Protection

            If you are building in an area with elevated radon potential, you must install radon protection. Although the precise areas where measures should be taken are listed in the BRE Guidelines (BRE 211 Radon: Guidance on Protective Measures for New Dwellings), these are reviewed by local government in the light of advice from the National Radiological Protection Board and the British Geological Survey. It is recommended that current information on the affected areas should be obtained from local authority building control officers or from approved inspectors. Note: Radon protection now applies to extensions and any change of use to a residential or sleeping use.

            Certified Installers at EBM

            When choosing an appropriate Radon barrier, levels should be assessed. It also needs to be decided what level of protection is required, whether it be a basic, passive-vented system or in exceptional circumstances a mechanical system may be required. EBM can aid the decision-making process and advise on appropriate materials to achieve the specification in accordance with BRE 211 recommendations and all installations are carried out by EBM NVQ level 2 installers.
