Professional Basement Conversions and Waterproofing in Swansea
White Rock Property Care help homeowners across South Wales unlock the full potential of their basements. Whether you’re starting from scratch or fixing a failed conversion, our expert team deliver fully waterproofed, regulation-compliant results that add lasting value to your property.
What is a basement conversion and why consider one?
A basement or cellar conversion is one of the most effective ways to create extra space in your home without extending outward. Whether you're looking to add a new bedroom, a home office, a gym or a cinema room, converting your basement unlocks a whole floor of underused potential.
Aside from the added functionality, a well-designed basement conversion can also significantly increase your property's value. However, converting a basement comes with unique challenges - the biggest being structural waterproofing; and that's where we come in.
Why is basement waterproofing essential?
Basements are naturally prone to damp and water ingress due to their below-ground location. Without proper waterproofing, a converted basement can quickly become unusable - and in some cases, dangerous.
At White Rock Property Care we specialise in structural waterproofing and tanking for basements and cellars across Swansea and South Wales. Our team includes PCA-certified surveyors who hold the CSSW (Certificated Surveyor in Structural Waterproofing) qualification. We design and install fully compliant systems in line with BS8102:2009, the UK standard for waterproofing below-ground structures.
What methods are used for basement tanking and waterproofing?
We tailor each waterproofing solution to the specific conditions of your property. This may include:
Cavity drain membrane systems
Internal waterproofing membranes
Drainage channels and sump pumps
Tanking slurry systems (cementitious coatings)
Perimeter waterproofing with Delta Membrane systems
As Registered Installers of Delta Membrane Systems, we meet the strict standards required to use their industry-leading range of products. From wall and floor protection to full basement drainage systems, we supply and install everything required to keep your space dry, safe and long-lasting.
Can you fix an existing basement conversion with waterproofing issues?
Simply put - yes. We’re often called in to repair or rectify poor-quality basement conversions. If your existing basement shows signs of damp, mould, structural damage or water ingress, our team can survey the space, identify the root cause, and carry out the necessary repairs to bring it up to standard.
Because we’re members of both the Basement Waterproofing Association and the British Structural Waterproofing Association, you can be confident that our methods and materials are fully compliant, accredited and backed by long-term guarantees.
What does the process look like?
It starts with a detailed survey by our qualified team. We’ll assess the condition of the basement and outline the best course of action, no matter whether you're starting from scratch or correcting past work. From there, your dedicated project manager will coordinate our surveyors, technicians and waterproofing specialists to deliver the conversion with minimum disruption and maximum results.
We work closely with homeowners, architects and planning authorities to ensure a smooth process from design to completion.
