Expansion joint sealing across White City

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Surface by surface

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement.

Brickwork and blockwork joints

Brick and block edges need careful preparation. Faces are prepared and primed wherever the sealant maker calls for it before the bead goes in.

Expansion joint sealing in White City, done properly

Few joints take as much punishment as those in a car park. Tyres load the edges, and de-icing salts and water work into any gap. A sealant suited to traffic and the expected movement goes in. If you are dealing with chipped joint edges on forklift routes and car park joints leaking onto vehicles below, we can put it right, whatever the surface. Most enquiries from White City start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Most London buildings can’t shut a car park, loading bay or warehouse floor for long. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.

Our workmanship is guaranteed for 12 months, in White City as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What happens if it’s left?

Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly, so it fails quickly. We cut out the old seal and prepare the faces every time. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

When to bring in a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

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.

Diagnose, treat, sign off

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. In White City, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Traffic, movement and joints around White City

London car parks, loading bays and podium decks often can’t close for long, which is why we work a few bays at a time. Less than 3 miles from White City there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

Retail centres such as Kensington Arcade (1.6 miles south-east of White City) have floors, service yards and car parks with joints under constant traffic. University campuses such as Imperial College London (less than half a mile north of White City) have car parks, paved walkways and building elevations with movement joints. For an occupier at a site such as Stable Way Industrial Estate, less than half a mile to the north-east of White City, the joints at loading doors and dock levellers usually see the hardest wear.

White City is about 1 mile north-west of Kensington, in Greater London. Our applicators travel to White City for work on movement joints. 764 places across Greater London fall within our area, White City among them. Sites around London have their own page, about 6 miles away.

Questions we are asked in White City

Do you cover business parks and estates near White City, such as Stable Way Industrial Estate?

Yes, sites like Stable Way Industrial Estate are within our area, along with the rest of White City. Send details of the unit and the work through our quote form for a quick quote.

Do you take on work at healthcare sites like Hammersmith Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

What exactly is a movement joint?

It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing, and either way it needs a sound seal.

Do the joint edges need to be sound before sealing?

Spalled edges need repairing before a new seal will last and we’ll flag every length affected. Sealing over them leads to early failure.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, with one point of contact.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Honest limits

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Damaged metal nosings or cover plates over a joint
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think before you book.
