Need expansion joint sealing in Westwood?

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

Our process

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Westwood, 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. 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 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. Each area is handed back after its cure time, under our 12-month guarantee.

Before we start on site

  • Point out any areas we must not close
  • Send asbestos survey details if the building is pre-2000
  • Flag any permit to work we’ll need

How we handle expansion joint sealing in Westwood

Long runs of brick or block have movement joints built in that most people only notice when the sealant has gone. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. The enquiries we see most involve expansion joints split through the centre of the bead and expansion joints filled with dirt and stones, on precast concrete panel joints, podiums and floor movement joints and cladding panel joints. Whoever orders the work in Westwood, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Halls, schools and small commercial buildings near places like Westwood have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Honest limits

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:

  • Leaks coming from the membrane rather than the joint seal
  • Crumbling edges that would give a new bead nothing sound to grip
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

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

Surfaces we seal

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

Common problems we fix in Westwood

Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons.

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

  • Joints where the bead has lost adhesion
  • Weathered movement joint sealant that no longer flexes
  • Previous reseals laid over old sealant
  • Debris jammed in movement joints

Hospital campuses such as Kent and Canterbury Hospital, 4.2 miles north of Westwood, grow in stages, leaving movement joints wherever new blocks meet old.

Common questions from Westwood clients

Is hospital work, at somewhere like Kent and Canterbury Hospital, something you do?

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

Will you take on work at estates like Barham Business Park, close to Westwood?

Yes, sites like Barham Business Park are within our area, along with the rest of Westwood. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Can a joint be sealed if the edges are broken?

Broken arrises have to be put right before resealing, and we’ll point out where that’s the case. Sealing over them leads to early failure.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

What exactly is a movement joint?

The general name is movement joint, and expansion joint is one common type. In everyday use the two names are often swapped.

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, phased so parts of the car park stay open.

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors.

Joints that move: notes for Westwood

Westwood sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints. Central London is about 56 miles from Westwood. 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.

Parks like Barham Business Park (to the south-east of Westwood) combine paved areas, car parks and building elevations, each with joints that move. A campus such as University for the Creative Arts (to the north of Westwood) has long runs of movement joint in its buildings, decks and paving.

Site staff or a sealant specialist?

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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

What happens if it’s left?

Resealing is normally the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we’ll tell you they need repairing first. Halls, stores and units around places like Westwood may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
