Tanking is crucial for anyone managing basements or cellars that are susceptible to moisture. Without effective tanking, water can infiltrate through walls and floors, resulting in dampness and potential structural complications. We implement tanking measures that establish a dependable waterproof barrier before any finishing touches, ensuring your space remains dry and secure.
Builders engaged in new developments or renovations depend on tanking to protect below-ground structures. Our tanking procedures involve meticulous surface preparation and precise application, preventing water entry that could jeopardize the construction. This method integrates seamlessly into the building timeline, providing durable outcomes that safeguard the project's integrity.
Homeowners dealing with damp basements or elevated water tables require effective tanking options to prevent mold and damage. We provide tanking services customized for existing homes, addressing trouble spots with a waterproof layer applied directly onto concrete or masonry. This process halts moisture at the source, maintaining your home's value and comfort.


Old timber shelving blocks access. When carrying out tanking in Streatham properties, we strip bare masonry right back to original brickwork because loose mortar crusts ruin bonds completely. You need clear floors across every passage, leaving room for heavy mixing buckets alongside ladders.
Cables need isolating early. We ask you to trace old copper water pipes, gas meters, and stray electrical conduit so an electrician can temporarily unclip them away from damp brickwork before our surface coats go on. Wet substrates produce dust when wire-brushed.
Tanking establishes a robust, waterproof layer that prevents water from breaching basements and below-ground walls, safeguarding your structure from damp conditions and damage.
With our careful application, tanking guarantees enduring resistance to water penetration, minimizing the need for expensive repairs later.
By blocking moisture accumulation, tanking aids in preserving the strength of concrete and masonry, preventing cracks and deterioration over time.
Effective tanking eliminates moisture sources that lead to mold growth, enhancing indoor air quality and fostering a healthier living environment.
Tanking is executed before any finishing work, allowing for a smooth continuation of plastering or other surface treatments without compromising waterproofing.
We conduct thorough inspections and repairs of surfaces prior to tanking, ensuring the waterproof layer adheres correctly and performs as intended.
From initial measurement to project completion, we keep you updated at every stage, delivering our tanking services punctually and to the specified requirements.
Water tracks downward fast. Tanking in Streatham homes works alongside perimeter channels beneath the floor slab, catching minor seepage behind coated bricks and directing flows away into collection pits. A blocked channel creates hidden pressures behind freshly coated masonry.
Rot threatens wet timber. We check where wooden floor timbers enter party walls, since masonry barriers stop liquid moisture but trapped ambient condensation can still settle against unvented wood ends. Good airflow keeps basement rafters solid.

We commence by inspecting the site to gauge moisture levels and pinpoint areas needing tanking, making sure we grasp the scope before any work commences.
Next, we clean and repair all surfaces, addressing cracks and imperfections to ensure the tanking membrane adheres effectively and forms a solid barrier.
We layer the waterproof coating, paying special attention to corners and joints where leaks are prone to occur, ensuring a continuous seal.
After application, we permit the tanking membrane to cure completely, followed by an extensive inspection to affirm the waterproofing is intact and effective.
Once the tanking is completed and confirmed, we communicate clearly with the client, provide any required documentation, and ensure the site is prepared for the next finishing phase.
Tanking establishes a robust waterproof barrier on basements and below-ground walls, halting moisture before it can penetrate your structure. We implement tanking meticulously over cleaned and repaired surfaces to ensure complete adhesion and coverage. This setup prevents dampness and water intrusion that could lead to mold or structural damage, securing your build's integrity from the ground up.
With our tanking, you receive enduring protection that withstands the trials of time. Our technique seals vulnerable segments like corners and joints, where leaks frequently begin, reducing future maintenance necessities. This method keeps basements dry and walls secure, supporting your property's overall lifespan without unexpected issues.


Frost delays chemical bonding. Cold basement brick stays stubbornly frigid during long winters, meaning slurry coats take many extra days to set firm before subsequent finishing layers can follow safely. Warm fans help circulate sluggish, cold room air.
Warm air holds moisture. Heavy muggy weather causes surface sweat on cold subterranean walls, which confuses homeowners who think newly laid tanking in Streatham has suddenly sprung fresh leaks. Humid air simply demands cross ventilation.
Heavy rain changes groundwater. Saturated earth outside presses directly against brick joints, testing every edge where subterranean coats meet the concrete floor base. We examine these tricky junctions closely.
With over 20 years in plastering and finishing, we bring practical experience to every tanking job. We begin by thoroughly assessing the site to identify moisture challenges before applying the waterproof membrane. Our tanking process emphasizes precision-cleaning surfaces, repairing cracks, and sealing joints to provide a lasting waterproof layer. This pragmatic method protects against damp and structural issues from the ground up.
We handle tanking as part of a cohesive service, coordinating each step from measurements to final inspections. Clear communication throughout the project prevents surprises and adheres to deadlines. The tanking membrane we apply is built to endure pressure, safeguarding basements and below-ground structures before any finishing work begins. Our methodical, straightforward execution yields results you can trust.

Craftsmanship you can see
Every plastering project we complete leaves walls smooth, durable, and ready for whatever comes next.
Shared structures often require party wall paperwork. When our work involves hacking off old render or anchoring membranes into an adjoining wall shared with next door, formal notices prevent boundary disputes later.
Covering damp patches with ordinary emulsion paint is frequent. Waterproof paints trap incoming liquid beneath cosmetic layers, blowing plaster off the masonry instead of addressing underground hydrostatic pressure behind the wall.
Slurry bonds directly against brickwork to hold back hydrostatic damp, while studded plastic membranes let seepages drain downward into channels. Your choice depends on brick condition and whether walls can support wet weight.
Clear every item out of the space completely. For properties in Streatham, moving old storage boxes and pulling timber workbenches off exterior walls gives our crew full room to scrub brickwork down.
