Groundworks in Tonbridge & Across West Kent

Patios, concrete bases, excavations, fencing, turfing, and pressure washing - the same trusted team that clears your drains. One contractor, no coordination delays. CHAS & SafeContractor accredited, £5m insured.

Drainage + Groundworks - One Contractor, Zero Complications

Most groundworks projects affect drainage - excavations disturb drain runs, patios need drainage falls connected to the existing system, and new concrete bases require drainage consideration at the design stage. Using one CHAS and SafeContractor accredited contractor for both avoids the cost, delays, and miscommunication of two separate trades working the same ground. One call. One team. One invoice. One guarantee.

This matters practically in Kent, where a significant proportion of groundworks projects involve disturbing ground near Victorian clay drain runs. When we open the ground for a patio base or a garden room foundation and find a drain that needs attention, we handle it in the same visit. You do not need to pause the project, source a second contractor, and wait for a second available date. We assess, we quote, we complete.

OUR GROUNDWORKS SERVICES

What We Do - Full Groundworks Service Across Kent

Smarter Drainage carries out a full range of groundwork services across Tonbridge and West Kent. Whether you need a reinforced concrete base for a garden room, a new patio laid correctly with drainage falls, professional fencing, or garden reinstatement after drainage work, we have the equipment and experience to do it properly.

Excavation Services

Residential and commercial excavations across Tonbridge and West Kent. We undertake both machine and hand dig depending on access and site constraints - particularly important for rear gardens and properties with narrow access typical of Kent terraced housing. We handle site clearance, topsoil strip, and ground preparation ahead of drainage installation, base laying, or patio construction.

When the excavation connects to or crosses an existing drain run, we carry out the drainage work at the same time - no need for a second trade to return.

Concrete Bases

Reinforced concrete bases for garden rooms, garages, sheds, and outbuildings. We follow a correct build-up: sub-base formation with compacted MOT Type 1 hardcore, blinding layer, reinforcement mesh to the correct specification, and concrete poured to the required depth. Getting this right from the start is the difference between a base that remains level for decades and one that cracks within a few seasons.

We advise on slab thickness and reinforcement based on the intended use - a garden room or timber-framed outbuilding has different load requirements to a garage or workshop. Drainage falls are always incorporated where required, and where a surface water connection is needed, we handle that too.

Patio Installation

We install patios in natural stone, porcelain, and concrete block paving. All are laid on a correctly prepared sub-base with the right drainage falls - this is especially important in Kent, where clay-heavy soils and seasonal rainfall cause standing water on poorly laid patios within a few winters. We get the drainage right from the sub-base up.

Natural stone and porcelain patios are increasingly popular in West Kent gardens - both are durable in our climate, but require full mortar bed installation rather than dry-lay to prevent movement. We advise on material choice for your budget and garden conditions. Where a channel drain or point drain is needed at the patio edge, we connect it to the existing drainage system as part of the same job.

A typical residential patio takes 2 to 4 days depending on size, ground conditions, and material.

Pressure Washing

Professional high-pressure washing for driveways, patios, paths, and external surfaces. Over a Kent winter, moss, algae, and black lichen build up quickly on natural stone and concrete surfaces - making them slippery and accelerating the staining into the surface material. Our commercial-grade pressure washers remove this without damaging the paving.

For block paving driveways and patios, we also re-sand the joints after cleaning and apply a penetrating sealant where requested - this protects the surface and reduces weed growth between the blocks. A thorough clean and re-seal typically extends the life of a block paving surface by several years.

Fencing Installation

Wooden fencing supply and installation - close-board privacy panels, post-and-rail, and custom designs. We handle everything from post foundations through to the finished panels, including the concrete spur repair or full post replacement where existing posts have rotted at ground level. Kent’s wet winters are hard on fence posts that have not been set correctly in concrete, and we get the post foundation right first time.

Supply and fit or fit-only where you have already sourced materials. We work with treated softwood and pressure-treated hardwood for longevity in the British climate.

Turfing & Lawn Laying

Fresh turf supply and laying with thorough soil preparation and levelling. A good result depends on what goes under the turf as much as the turf itself - we remove debris, break up compacted ground, incorporate a layer of good topsoil, and level before laying. This gives the grass the best possible start and reduces patching in the first season.

Turfing is frequently combined with other groundworks jobs - reinstating a lawn after a drainage excavation, finishing a garden after a patio installation, or completing a landscaping project that has involved significant ground disturbance. We coordinate the turf laying as the final stage of a larger project, meaning you get a clean, finished garden rather than a churned-up site waiting for a second contractor.

Sewage Treatment Plant Installation

We install domestic and commercial sewage treatment plants and upgrade old septic tanks to compliant treatment plants. As a combined drainage and groundworks team we carry out the excavation, base, plant installation, drainage field and full reinstatement in one project, so there is no juggling separate trades.

Frequently Asked Questions - Groundworks

Yes. We carry out all types of groundworks - excavations, concrete bases, patios, fencing, turfing, and pressure washing - across Tonbridge and a 20-mile radius of West Kent and the surrounding areas, including Tunbridge Wells, Maidstone, Sevenoaks, Paddock Wood, Hildenborough, and surrounding towns.
Yes - and this is one of our strongest advantages. As a drainage and groundworks contractor, we can carry out excavation, drainage connection or repair, and surface reinstatement in a single coordinated project. This avoids the cost and delays of using two separate contractors, and means we only need to open the ground once.
We lay reinforced concrete bases using a correctly prepared sub-base of compacted hardcore (MOT Type 1) with reinforcement mesh for added strength. The slab specification depends on the size and intended use - we advise on the correct thickness and reinforcement level for your project before quoting. Surface drainage falls are incorporated as standard where required.
Concrete base costs depend on size, depth, reinforcement requirements, and site access. We recommend a free, no-obligation site visit so we can assess the ground conditions and give you an accurate quote. Call 07572 433507 or use the contact form to arrange a visit.
Yes. All patios we lay include correct drainage falls, and where needed we install a channel drain or point drain connected to the existing drainage system. This is especially important on Kent clay soils where seasonal rainfall can cause surface water pooling on poorly drained patios.
We install patios using natural stone, porcelain paving, and concrete block paving. We advise on the right material for your budget and garden conditions - all are laid on a proper prepared sub-base with the correct mortar bed or bedding layer to prevent movement and cracking.
Yes. We provide professional high-pressure washing for driveways, patios, paths, and external surfaces. This removes moss, algae, oil staining, and general weathering. For block paving we can also re-sand the joints and apply a penetrating sealant to protect the surface and reduce weed growth.
Yes. We supply and fit wooden fencing - close-board panels, post-and-rail, and custom designs. We handle everything from post foundations to finished panels. Fit-only is also available if you have already sourced your own materials.
Yes. Smarter Drainage holds £5 million public liability insurance covering all drainage and groundworks operations across Kent. We are also CHAS Accredited and SafeContractor Approved - both independent assessments of our health, safety, and business standards.
A typical residential patio takes 2 to 4 days depending on size, ground conditions, and the chosen material. We will give you a clear timeline as part of your free quote before any work begins.
Yes. We carry out excavation, sub-base preparation, and surface laying for driveways as part of our groundworks service. Where a new driveway crosses or disturbs a drainage run, we handle both the groundwork and the drainage element - one contractor, one project, no complications.
Yes. Garden reinstatement including turfing is frequently the final stage of a drainage excavation project. We prepare the soil, level the ground, and lay fresh turf so you are left with a finished garden rather than a disturbed site waiting for a second contractor to return.
