Where floor joints take the most wear near Swanton

The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints. Swanton has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Across sites such as Mereworth Business Centre (1.8 miles east of Swanton), floor and movement joints can be sealed in phases so units keep working. A healthcare site such as Maidstone Hospital, 5.7 miles east of Swanton, depends on car parks, ramps and service yards whose joints take traffic all day.

Swanton is about 5 miles north-east of Tonbridge, in Kent. We cover commercial sites throughout Swanton, whether it’s a single job or part of a planned programme. Swanton is one of 931 places in Kent on our list for movement joints. There’s a separate page for London, roughly 26 miles from Swanton.

Postcode districts covered here: ME18. Just outside Swanton, we also work in West Peckham (1 mile south), New Pound (1 mile north-east), Mereworth (1 mile east), Herne Pound (1 mile north-east) and Roughway (1 mile west). Nearby towns on our patch include Maidstone (8 miles east), Dartford (14 miles north-west), Sevenoaks (7 miles west), Royal Tunbridge Wells (9 miles south-west), Gravesend (12 miles north) and Tonbridge (5 miles south-west).

Expansion joint sealing in Swanton

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in and the work can be phased so parts of the car park stay open. We work on brickwork movement joints, car park decks and ramps and cladding panel joints, and the failures we are asked to look at most are water getting into the wall through a failed joint and previous reseals laid over old sealant. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Swanton is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Jobs around smaller places like Swanton are planned so the whole job is done in one visit. Note joint widths and the traffic that uses them, and we will take it from there.

Every job we finish is backed by a 12-month workmanship guarantee, in Swanton as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Leave it or put it right?

A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. We’ll flag where edges need repair before sealing. Halls, stores and units around places like Swanton may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Why clients in Swanton choose us

  • Colour agreed before work starts
  • Health and safety: CHAS accredited
  • Work to your specification and the manufacturer’s guidance
  • A range of standard colours, depending on the product

Take a look at what affects the cost or how we’re accredited.

How the quote is worked out

To price the job, we consider:

  • The site’s rules and procedures
  • Travel to remote or island sites
  • Backing rod, priming and other preparation
  • Which sealant the job calls for

The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Drawings or a marked-up plan, if available
  • Anything awkward about access or site hours
  • A wide shot and a close-up of the area
  • The asbestos register, for older buildings

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call the office on 01277 525 020 or email us.

Do you need expansion joint sealing in Swanton?

Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. BS EN ISO 11600 classifies building sealants by movement capability.

Clients typically get in touch after noticing something like this:

  • Sealant pulling off the joint face
  • Brittle, chalky sealant on external joints
  • Torn sealant in brick or block movement joints
  • Joints packed with grit and debris

For a school such as Mereworth Community Primary School, playground and building joints can be done in the holidays.

Questions to ask before you book

  • Which product they’ll use, and why it suits the joint
  • What the guarantee covers, and for how long
  • Health and safety accreditation such as CHAS
  • Their public liability cover

Questions to ask before you appoint anyone

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Leaks coming from the membrane rather than the joint seal
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Damaged metal nosings or cover plates over a joint

If you’re not sure, just give us a call on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Surfaces we seal

  • Blockwork control joints
  • Podiums and floor movement joints
  • Cladding panel joints
  • Precast concrete panel joints
  • Brickwork movement joints
  • Car park decks and ramps

On site: what to expect

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. Jobs in and around smaller places like Swanton are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

What we need from you

  • Share the asbestos register for older buildings
  • Send your site hours and access windows
  • Make sure the joints can be reached

Questions about Swanton

Does your area include sites such as The Alders Industrial Estate, near Swanton?

Yes, sites like The Alders Industrial Estate are within our area, along with the rest of Swanton. To start, just phone 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Is Swanton too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

What site paperwork can you supply?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Are expansion joints and movement joints the same thing?

The terms overlap a great deal. A movement joint allows for expansion, contraction, shrinkage and loading.

How long does movement joint sealing take?

Allow a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Timings are set out in the quote.

Can you quote from photos?

It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

Doing it in-house

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
