Dealing with Flooded Basements in Southampton
Properties in Southampton can be particularly vulnerable to flooding due to their proximity to the coast, as well as several converging rivers. Basements in the area can be particularly vulnerable to flooding during periods of heavy rainfall or due to drainage issues. Without the right system in place, your property could be at risk of regular flooding.
We design waterproofing systems that help manage and control water, reducing the risk of future flooding and protecting your property. Our bespoke designs work with your property, how you use your basement, and its structural vulnerabilities, creating a system that works for you.
Basement Tanking or Type A Waterproofing
Type A waterproofing is commonly known as basement tanking or barrier protection. It involves applying waterproof coatings or membranes directly to the structure to block water ingress. When applied correctly, it creates a continuous waterproof barrier applied directly to the internal surfaces.
This approach is effective where water pressure is controlled, but it often works better as part of a combined waterproofing system, alongside Type B or C waterproofing. During your survey, our experts can confirm whether Type A systems are appropriate for your basement and whether you would benefit from combined waterproofing.
Type C Waterproofing or Cavity Drainage Systems
For effective, BS1802-compliant basement waterproofing, we usually offer a combination of Type A and Type C systems. Type C systems, also known as cavity drainage systems, manage water rather than stopping it at the point of entry. A cavity drain membrane is installed to channel moisture into a drainage system, which safely removes it from the property via a sump pump unit.
This method is often preferred for habitable spaces or where ongoing water ingress is likely. It provides a controlled and reliable way to keep basements dry. Our basement waterproofing services in Southampton focus on long-term performance, helping you protect your investment and avoid repeat issues.
Whilst we often have same-week availability in Southampton, it can be dependant on demand. Call 01489 807063 to speak to us and find the earliest survey appointment that works for you.
