Expansion joint sealing for Tonge Corner sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Expansion joint sealing in Tonge Corner, done properly

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load so the product has to suit both the traffic and the movement. If the arrises are already broken, we’ll say so before sealing and phasing can keep areas working. The enquiries we see most involve debris jammed in movement joints and movement joints with split or torn sealant, on podiums and floor movement joints, brickwork movement joints and cladding panel joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Tonge Corner is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a site near Tonge Corner, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we will take it from there.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, give us a call on 01277 525 020 or email us and we’ll arrange a return visit.

Questions we are asked in Tonge Corner

Can you work on a hospital site such as Sittingbourne Memorial Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Our building in Tonge Corner is near the coast: does that change the sealant?

It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.

Can you seal car park deck joints?

Yes. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed.

How much does the work cost?

It depends on the job: quantities, access, the product and any phasing. Call for a quote and we will price it properly.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Can you seal joints in cold or wet weather?

Outside work depends on conditions because a damp or frozen joint won’t take a proper bond. Internal floor joints are far less affected.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

On site: what to expect

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Rural sites near Tonge Corner may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Warn occupants and staff about the work
  • Point out parking and an unloading spot

Getting a fixed quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Advice

When to call us in Tonge Corner

Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability.

It’s worth sending us details if you spot any of the following:

  • Leaks through car park deck joints onto the level below
  • Sealant peeling off one face of the joint
  • Debris jammed in movement joints
  • Spalled or broken joint edges in floors and decks

Large sites such as Sittingbourne Memorial Hospital, 1.9 miles west of Tonge Corner, have car parks, service roads and long elevations with movement joints in brick and panels.

What your quote should include

  • How they’ll work around occupants
  • Whether primer will be used where the manufacturer specifies it
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their public liability cover

Choosing a commercial sealant contractor

Why it’s worth doing now in Tonge Corner

A failed joint seal doesn’t mean the slab, panel or wall needs replacing. If the material either side is sound, a properly prepared reseal restores the joint. We will flag where edges need repair before sealing. Converted and older buildings near places like Tonge Corner tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Why us?

  • Constructionline member
  • 12 months’ guarantee on every job
  • Colours confirmed for the specified product
  • Over 20 years of commercial sealing

See our cost guide or how we’re accredited.

Maintenance after handover

Once the work is signed off, a little attention goes a long way:

  • Check joints after long freezing spells
  • Include every elevation and deck joint in periodic inspections
  • Keep racking legs and heavy point loads off floor joints
  • Clear dirt from joint lines during routine cleaning

Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. Regular sweeping keeps joint lines clear.

On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Sealing the joint promptly stops it at source.

Warehouse floors and decks around Tonge Corner

The sea is no more than about 2 miles from Tonge Corner. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so a failed joint lets more in and the edges break up sooner. At about 39 miles from central London, Tonge Corner is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day.

In a school such as Lansdowne Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Doing it in-house

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

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

Cost factors for movement joints

There’s no standard rate for sealant work, because every site is different. What we look at:

  • How much existing material needs removing
  • Induction, permit and paperwork requirements
  • Working within restricted access windows
  • Quantities, in metres or numbers

A quote for movement joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Details that help us quote

Whether it’s one area or a whole building, these details speed things up:

  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work
  • The site address and postcode
  • The product your specification calls for

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or email a schedule or drawings.
