Tanking is crucial for anyone dealing with moisture-prone basements or cellars. Without effective tanking in place, water can infiltrate walls and floors, leading to dampness and structural challenges. We implement tanking solutions that form a dependable waterproof barrier before any finishing work starts, ensuring that the space remains dry and structurally sound.
Builders engaged in new constructions or renovations rely on tanking to shield below-ground structures. Our tanking process includes rigorous surface preparation and exact application, preventing any water ingress that could threaten the build. This method integrates seamlessly into the construction schedule, providing lasting results that uphold the integrity of the project.
Homeowners dealing with damp basements or rising water tables need reliable tanking solutions to prevent mold and damage. Our tanking services are designed for existing properties, focusing on problem areas with a waterproof layer applied directly to concrete or masonry. This approach stops moisture at its source, preserving the home's value and comfort.


Old storage boxes create major obstacles. You need clear walkways from the front driveway down to the basement stairs so our crew can carry heavy buckets without tripping over garden hoses. When scheduling tanking in Redhill, clearing every timber offcut from brickwork gives us the bare masonry we need.
Plumbing demands care. A rusty cold-water pipe pinned tightly against damp brickwork stops our trowels cold, meaning a plumber should unclip or reroute that pipework before we coat the wall behind it. If live electrical cables run across the mortar, shut off the breaker before we touch that corner.
Tanking creates a solid, waterproof layer that prevents water from penetrating basements and below-ground walls, thus protecting your property from dampness and damage.
Through our precise application, tanking ensures long-lasting resistance to water ingress, minimizing the need for expensive repairs later.
By averting moisture buildup, tanking helps sustain the strength of concrete and masonry, preventing cracks and deterioration over time.
Effective tanking eliminates moisture sources that foster mold growth, leading to improved indoor air quality and a healthier environment.
Tanking is performed prior to any finishes, enabling a smooth continuation of plastering or other surface treatments without compromising waterproofing.
We inspect and prepare surfaces thoroughly before tanking, ensuring that the waterproof layer bonds properly and functions as intended.
From measuring to completion, we keep you updated at every phase, delivering tanking services punctually and to specifications.
Pipes breach barriers easily. If your central heating copper runs through the external brickwork into the cellar, vibrating sleeves can break standard coatings, so we seal around those sleeves using flexible collars. Booking your tanking in Redhill means treating every single pipe collar before anyone hangs a radiator back on the masonry.
Basements often collect greywater. When you install an automatic pump chamber beneath floor level, our wall barrier must marry up with the plastic sump perimeter rim without leaving gaps for pooling water. That prevents liquid rising through the slab junction directly into your utility room washing machine wiring.

We begin by evaluating the site to assess moisture levels and pinpoint areas requiring tanking, making sure we grasp the scope before starting any work.
Following that, we clean and repair all affected surfaces, addressing cracks and imperfections to ensure that the tanking membrane will adhere correctly and form a solid barrier.
We apply a waterproof coating in layers, focusing particularly on corners and joints where leaks frequently emerge, ensuring a secure and continuous seal.
After the application, we allow the tanking membrane to cure thoroughly, subsequently conducting a detailed inspection to verify that the waterproofing is effective.
Once the tanking is finished and confirmed, we communicate clearly with the client, provide necessary documentation, and ensure the site is ready for subsequent finishing stages.
Tanking establishes a robust waterproof barrier on basements and below-ground walls, halting moisture before it can penetrate the structure. We carefully apply tanking over thoroughly cleaned and repaired surfaces to guarantee complete adhesion and coverage. This prevents dampness and water ingress that can lead to mold or damage, safeguarding the integrity of your project from the ground up.
With our tanking, you're getting enduring protection that withstands the test of time. Our method seals critical areas like corners and joints where leaks usually start, lessening future upkeep needs. This approach keeps basements dry and walls intact, enhancing the overall lifespan of your property without unexpected issues later.


Saturated soil creates pressure. Constant downpours push ground moisture deep against subterranean retaining walls, which quickly shows whether an old cellar has active hydrostatic seepage through lime mortar. Undertaking tanking in Redhill during prolonged wet spells requires managing standing puddles on the concrete floor with sponges before applying base coats.
Warm weather brings risks. Blasts of dry summer air make cementitious slurries dry out far too quickly, turning fresh coatings brittle instead of letting them bond to dense masonry blocks. We mist walls with clean water to prevent powdery patches beside low basement air vents.
Chilly bricks collect moisture. Humid air from tumble dryers condenses on uninsulated mortar faces, mimicking ground seepage even when the masonry is sound. Good airflow stops droplets gathering along cold skirting channels.
With over two decades in plastering and finishing, we bring hands-on experience to every tanking project. We start by thoroughly assessing the site to identify moisture risks before applying the waterproof barrier. Our process focuses on precision-cleaning surfaces, addressing cracks, and sealing joints to ensure a long-lasting waterproof layer. This practical approach prevents damp and structural damage from the ground up.
We manage tanking as part of a complete service, coordinating every step from measuring to final inspection. We communicate transparently throughout the project to avoid surprises and meet agreed-upon deadlines. The tanking membrane we apply is designed to withstand pressure, safeguarding basements and below-ground walls before any finishing work starts. Our meticulous, straightforward execution delivers dependable results.

Every plastering project we complete leaves walls smooth, durable, and ready for whatever comes next.
No. The coating needs time to cure completely, because trapping moisture under vinyl emulsion or non-breathable oil paint causes blistering. You should wait until the surface turns a uniform pale shade, and then apply breathable masonry paint or specialized plaster.
It depends on where the barrier sits. If you share a subterranean brick wall with the terrace house next door in Redhill, hacking off old plaster or drilling can affect their property, meaning an agreement or written notice is required before starting work.
Ask how they handle floor and wall intersections. A skilled tradesperson explains the bottle cove detail and how corners are reinforced, because true competence shows in joint details rather than quick promises about finishing early.
Stripping decayed timber studs, moving consumer units, and digging sumps are rarely included. If an old coal chute has rotten woodwork or crumbling lintels, brick repairs and carpenter callouts are charged as extra work beyond the wall barrier itself.
