Tanking is crucial for anyone managing basements or cellars susceptible to moisture. If not addressed with proper tanking, water may seep through surfaces, leading to dampness and structural problems. Our tanking services establish a dependable waterproof barrier in Thamesmead before any finishing work starts, ensuring the area remains dry and secure.
Builders engaged in new projects or renovations depend on tanking to protect below-ground elements. Our tanking approach involves thorough surface preparation and precision application, preventing water ingress that could jeopardize the construction integrity. This method integrates smoothly into the building timeline, providing resilient outcomes that uphold your project’s quality.
Homeowners dealing with moist basements or rising water levels require effective tanking solutions to avert mold and damage. We provide tailored tanking services in Thamesmead that address specific issues with waterproof layers applied directly to concrete or masonry. This service halts moisture at its source, maintaining the home's value and comfort.


Strip every wall bare first. When undertaking tanking in Thamesmead, our team needs immediate physical access to brickwork, so you must shift timber offcuts, old paint tins, and heavy workbenches away from cold boundary corners. Any stubborn timber battens fixed directly into mortar joints must come down before we arrive.
Loose cables cause severe delays. If exposed copper pipes run tight against a brick surface, pipe clips must come off so fresh coatings can slide completely behind the copper. You ought to ask an electrician to isolate low consumer unit cables early, keeping everyone safe from shocks while surfaces stay wet.
Our tanking creates a solid, waterproof layer that prevents water from entering basements and below-ground walls, safeguarding your structure from dampness and damage.
With our precise tanking application, residents in Thamesmead achieve lasting resistance to water ingress, minimizing the need for expensive repairs later on.
By averting moisture buildup, our tanking service helps maintain the strength of concrete and masonry, preventing cracks and deterioration over time.
Effective tanking blocks moisture sources that lead to mold growth, enhancing indoor air quality and fostering a healthier living environment.
Tanking is applied ahead of any finishes, allowing plastering or other treatments to proceed without compromising waterproofing.
We conduct thorough inspections and repairs before tanking, ensuring the waterproof layer bonds appropriately and functions as expected.
From initial measurements to project completion, we keep clients informed, delivering tanking services promptly and to your specification.
Water pipes sweat in winter. While applying slurry layers during tanking in Thamesmead homes, cold waste pipes crossing floors demand specialised collar sleeves around joints, otherwise moisture tracks inward along metal brackets. We smooth compounds right up against incoming water mains, leaving room for future stopcock repairs without cracking the shell.
Never block external ventilation paths. Subfloor airbricks keep joists dry above ground level, which means protective coatings must stop precisely below air sleeves so airflow keeps moving continuously. Smearing sticky slurry over a vent opening chokes joists, quickly causing dry rot in floorboards directly overhead.

We begin by assessing the site to gauge moisture levels and pinpoint areas needing tanking, ensuring we grasp the full scope before beginning any work.
Afterwards, we clean and repair all surfaces, mending cracks and imperfections to guarantee the tanking membrane adheres well and forms a strong barrier.
We apply the waterproof coating in stages, being meticulous around corners and joints where leaks often happen, ensuring a continuous seal.
Once applied, we let the tanking membrane cure thoroughly, followed by a detailed inspection to confirm that the waterproofing is effective and intact.
Upon completing the tanking and confirming its integrity, we clearly communicate with the client, provide necessary documentation, and prepare the site for the subsequent finishing phases.
Rawlplugs puncture protective layers instantly. Once we finish tanking in Thamesmead, hanging heavy steel shelving or boiler brackets requires specialized expanding sealing plugs rather than bare steel screws driven blindly into treated masonry. A single misplaced masonry drill bit breaks the entire barrier, letting groundwater pool silently behind skirting boards.
Wipe drops off cold surfaces. Tanked walls block liquid ground pressure entirely, yet warm humid air from a tumble dryer can still condense on chilled render coats. Running a basic dehumidifier stops harmless surface puddles forming near corners, preventing black spots on fresh decorative paint.


We bring over two decades of hands-on experience in tanking, delivering waterproofing techniques that endure. Understanding how crucial a well-executed tanking layer is in preventing water ingress in basements, each project demonstrates our commitment to thorough preparation and precise application, ensuring the tanking performs effectively.
Tanking requires careful inspection and meticulous execution, particularly around corners and joints, which are prone to leaks. We prioritize cleaning, repairing cracks, and applying multiple layers for a long-lasting seal. This commitment to detail minimizes future problems and guarantees that the waterproofing barrier remains effective prior to any finishes.
From the first measurement to the final agreement, we maintain open communication with builders and clients. Our tanking service aligns with project schedules, preventing delays and ensuring the waterproofing is completed as agreed. This pragmatic approach contributes to a smooth building process and reliable moisture protection.
With over 20 years in plastering and finishing, we use our extensive experience for every tanking project. We start with a thorough site assessment to identify moisture risks before applying the waterproof barrier. Our tanking procedure emphasizes precise surface cleaning, mending cracks, and sealing joints to guarantee a durable waterproof layer. This effective approach stops dampness and structural damage at the source.
We handle tanking as part of a complete service, coordinating every step from initial measurement to final inspection. We keep clients updated throughout the process to prevent surprises and adhere to deadlines. The tanking membrane we utilize is engineered to withstand pressure, protecting basements and below-ground walls prior to finishing work. Our meticulous, straightforward execution delivers results you can trust.

Craftsmanship you can see
Every plastering project we complete leaves walls smooth, durable, and ready for whatever comes next.
We visit to inspect wall substrates, calculate compound quantities, strip failed plaster, apply the barrier coats evenly, and finally check surfaces once dry. When delivering tanking in Thamesmead, we confirm timelines openly before carrying gear inside.
Ripping out old timber studwork, shifting heavy stored furniture, replacing decayed floorboards, or re-routing copper plumbing usually incur separate charges because general trades handle joinery and gas pipework better than plastering teams.
Slurry bonds directly to masonry to hold back ground pressure, whereas dimpled membranes let water track downward into drainage channels. Choosing between them depends entirely on wall strength, ceiling heights, and groundwater levels.
We inspect every square inch with you, check corners for damp patches, provide clear guidelines on hanging shelves, and remain available on the phone if your decorator has questions about breathable paints.
