Expansion joint sealing for commercial buildings in Charlton-in-Dover

Internal floor joints take trolleys, pallet trucks and forklifts. Without a sound filler, joint edges chip and spall under load so the product has to suit both the traffic and the movement. We will tell you if the edges need repairing before sealing and phasing can keep areas working. We work on precast concrete panel joints, brickwork movement joints and blockwork control joints, and the usual reasons a site gets in touch are chipped joint edges on forklift routes and layers of sealant in a movement joint. Searching for sealant specialists in Charlton-in-Dover? We’ve been sealing commercial buildings since 2005.

Rural business units around smaller places such as Charlton-in-Dover often have new slabs laid inside older buildings. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What the job involves on each surface

Joints between different materials

Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves.

Concrete and precast panel joints

Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Include every elevation and deck joint in periodic inspections
  • Look over external and deck joints after a hard winter
  • Keep stones and debris out of open joint lines
  • Act on the first tear or lifting edge rather than waiting

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check. Should you spot a problem, you can ring 01277 525 020 or email the details over and send a picture.

Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. A sound seal keeps the joint working.

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. What matters most for a job in Charlton-in-Dover is a clear list of what needs doing, so send photos of each area. You will then get a fixed price for the work.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  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. Each area is handed back after its cure time, under our 12-month guarantee.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Point out any areas we must not close
  • Send asbestos survey details if the building is pre-2000

Common questions from Charlton-in-Dover clients

Can you work on a hospital site such as Buckland Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Can you work at a site such as White Cliffs Business Park, by Charlton-in-Dover?

Yes. We cover Charlton-in-Dover and the area around it, including industrial estates, business parks and retail parks such as White Cliffs Business Park. Send details of the unit and the work through our quote form for a quick quote.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Can you work while the building is occupied?

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

How long does movement joint sealing take?

It normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Timings are set out in the quote.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Floors, slabs and movement joints in Charlton-in-Dover

Charlton-in-Dover lies within about 1 mile of the sea. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so a failed joint lets more in and the edges break up sooner. Charlton-in-Dover is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.

Business parks such as White Cliffs Business Park, 1.3 miles north of Charlton-in-Dover, have car parks, paved areas and long brick and panel elevations, all with movement joints. Hospital campuses such as Buckland Hospital, 0.7 miles to the west of Charlton-in-Dover, grow in stages, leaving movement joints wherever new blocks meet old. In a school such as Charlton Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:

  • A joint that has to be widened or re-detailed before it can work
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Broken or spalled joint edges, which need repairing before any sealant goes in

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
