Expansion joint sealing for commercial buildings in Bexon

Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. We work on podiums and floor movement joints, brickwork movement joints and car park decks and ramps, and what we’re called in for most is brittle, chalky sealant on external joints and car park joints leaking onto vehicles below. A specialist sealant contractor works differently from a general builder: in Bexon, that means joint design, primers and backing rod as standard.

Jobs around smaller places like Bexon are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Where floor joints take the most wear near Bexon

Bexon is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open. Bexon lies roughly 37 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift.

University campuses such as Canterbury Christ Church University, 2.8 miles to the south-west of Bexon, have car parks, paved walkways and building elevations with movement joints. For a school such as Bredgar Church of England Primary School, playground and building joints can be done in the holidays.

Bexon is about 3 miles south of Sittingbourne, in Kent. If you are looking for expansion joint sealing in Bexon, we can help. 931 places across Kent fall within our area, including Bexon. London is covered too, some 37 miles away.

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

When to call us in Bexon

Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.

Site and facilities staff are often the first to spot these:

  • Hardened, cracked sealant on exposed facades
  • Joints where the bead has lost adhesion
  • Previous reseals laid over old sealant
  • Expansion joints split through the centre of the bead

On a site such as Kent Science Park, 0.9 miles to the north-east of Bexon, the movement joints are in car park slabs, paving and building elevations.

How to choose a sealant contractor

When it isn’t the sealant

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

  • Concrete or masonry repairs along the arrises
  • Movement on a scale no sealant is meant to absorb
  • Changing the joint layout or spacing of a structure

If in doubt, phone 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Joints and surfaces we work on

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

Bexon: questions and answers

Can you take on a job at a hospital such as Sittingbourne Memorial Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Is a smaller place like Bexon outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Why do our movement joints keep failing?

It depends on how the sealant has let go: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Broken edges are a third possibility.

Does the weather affect the work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Can you quote from photos?

It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.

Can staff carry on working while you are here?

Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

Can you work on car park ramps and decks?

Yes. We use a sealant designed for wheel loads and the expected movement.

Our process

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For a building around Bexon, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. Photos, joint lengths and drawings come to us, or we visit.
  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. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Getting the site ready

  • Confirm the product named in the specification
  • Tell staff and tenants when we will be in
  • Send your site hours and access windows

Work for main contractors and building owners

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Maintenance after handover

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Treat a small split as a warning, not a cosmetic issue
  • Note which joints were done, when, and with what
  • Avoid parking heavy plant or pallets on joint lines
  • Reopen bays and walkways only after the stated cure time

Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records.

A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it, which is bad news for the concrete and the people parking below. Resealing early limits the damage.
