Tanking is crucial for anyone facing moisture issues in basements or cellars. Without effective tanking, water can seep through walls and floors, causing dampness and structural problems. We provide tanking solutions that create a dependable waterproof barrier, ensuring your space remains dry and secure.
Builders engaged in new projects or renovations depend on tanking to protect below-ground constructions. Our tanking process includes thorough surface preparation and precise application, preventing water ingress that could compromise the structure. This method integrates smoothly into the construction timeline, delivering lasting results that safeguard project integrity.
Homeowners experiencing damp basements or rising water levels require effective tanking solutions to prevent mold and damage. We offer tanking services customized for existing properties, applying a waterproof layer directly on concrete or masonry. This service halts moisture at the source, preserving the value and comfort of your home.


Our focus is on tanking in Brentwood for basements, cellars, and any below-ground walls needing protection from water ingress. We apply waterproofing layers before any finishing work, ensuring the surfaces are completely sealed against moisture. This method prevents dampness and structural issues that arise from water penetration in these essential areas.
The tanking service begins with a thorough site inspection and surface preparation to ensure proper adhesion of the waterproof barrier. We apply the tanking membrane in precise layers, focusing on corners and joints where leaks often occur. The outcome is a lasting, watertight seal that integrates perfectly with subsequent plastering and finishing tasks.
Tanking establishes a solid, waterproof layer that prevents water from penetrating basements and below-ground walls, safeguarding your structure from dampness and potential damage.
With our precise application, tanking provides enduring resistance to water ingress, lessening the risk of costly repairs in the future.
By blocking moisture accumulation, tanking helps maintain the strength of concrete and masonry, preventing cracks and weaknesses over time.
Effective tanking cuts off moisture sources leading to mold growth, enhancing indoor air quality and fostering a healthier environment.
Tanking is applied prior to any finishes, allowing for a smooth continuation of plastering or other surface treatments without compromising waterproofing.
We thoroughly inspect and repair surfaces before tanking, ensuring the waterproof layer adheres effectively and performs as intended.
From measurements to completion, we keep you informed at every step, delivering tanking services on schedule and to your specifications.
Old copper waste pipes and heavy cast-iron soil stacks often run straight through masonry below ground level. We pack specialised collars tight against brick courses. When arranging tanking in Brentwood, our team checks each sleeve carefully so water cannot seep past your main supply line, leaving room for later maintenance.
Plumbing comes second. If a plumber wants to fix radiator brackets to external walls later, standard rawl plugs will punch holes through our fresh barrier, letting groundwater pool behind baseboards. We mark designated fixing strips across mortar beds beforehand so your heating engineer hangs modern radiators without ruining the barrier seal.

We start by inspecting the site to assess moisture levels and locate areas requiring tanking, ensuring clarity of the scope before any work commences.
Next, we clean and repair all surfaces, addressing cracks and defects to ensure the tanking membrane adheres properly and forms a solid barrier.
We apply the waterproof coating in layers, paying careful attention to corners and joints where leaks are most likely, ensuring a continuous seal.
After application, we allow the tanking membrane to cure properly, then conduct a thorough inspection to confirm the waterproofing is intact and effective.
Once the tanking is finished and verified, we communicate clearly with the client, provide necessary documentation, and prepare the site for the next stage of finishing.
Heavy slurry buckets need wide paths. Carrying tubs of dense bonding compound through tight hallways requires clearing side tables, coats, and boot racks before we arrive on site. For tanking in Brentwood homes, moving bicycles and washing machines out of the cellar beforehand keeps heavy sacks from brushing your wallpaper.
Chipping old mortar creates grit. We hang polythene sheeting over internal doors to keep grey powder away from your kitchen surfaces and living areas. Open a cellar hopper window slightly to pull airborne particles outward while we hack away failing Victorian plaster from the cold brickwork.


Autumn rainfall raises hydrostatic pressure outside foundation walls. Clay soil swells against the footings, trying to push damp inward through unseen cracks. When completing tanking in Brentwood, we remind owners that external earth stays soaked for months, meaning inner walls must remain unpainted until damp meters drop completely.
Cold air holds less moisture. Running a basic dehumidifier in unheated basements stops warm domestic air from condensing against cold internal barrier coats. Without adequate ventilation, droplets run down freshly skimmed surfaces, soaking cardboard boxes stacked directly on the bare concrete floor slab.
Keep belongings slightly elevated. Wooden shelving units or plastic crates should sit away from treated walls rather than flat against rendered surfaces. Air must circulate freely along external boundaries so stored luggage stays dry during humid summer months.
With over two decades in plastering and finishing, we bring hands-on expertise to every tanking project. We start by thoroughly assessing the site to identify moisture risks before applying the waterproof barrier. Our tanking method prioritizes precision cleaning of surfaces, fixing cracks, and sealing joints to provide a durable waterproof layer. This practical approach prevents damp and structural damage right from the ground level.
We manage tanking as part of a comprehensive service, handling each step from measurement to final inspection. Clear communication throughout the project helps avoid surprises and meet deadlines. The tanking membrane we use is designed to withstand pressure, protecting basements and below-ground walls before any finishing work starts. Our disciplined, straightforward execution yields reliable results.

Craftsmanship you can see
Every plastering project we complete leaves walls smooth, durable, and ready for whatever comes next.
We walk you through the space to inspect the barrier coats and discuss drying times. Plaster takes days to cure fully before any decorative trade can step inside. If you notice unusual damp patches on walls later, we return to examine the specific joint.
It depends on where your walls sit, because shared party walls often require written notice under property legislation. In Brentwood, terraced basements frequently touch neighbouring footings, so informing adjoining owners prevents disputes over vibrations caused by stripping back old lime render.
Freezing conditions prevent cementitious slurries from bonding correctly to chilly brickwork. We monitor background room temperatures closely because materials crack if frost gets into uncured mixes. In heavy rain, rising ground pressure simply tests our seals faster once the slurry hardens.
Empty the room entirely. Move storage boxes, timber scraps, and disused appliances into your garden shed or garage so our plasterers reach every corner. We also require a working cold water tap and a safe electrical socket nearby for mixing paddles.
