Expansion joint sealing for Shirley sites

Expansion joint sealing for commercial buildings in Shirley

Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it, and we’ll confirm the choice in the quote. If you have expansion joints split through the centre of the bead and arrises breaking up along floor joints, we can help, on blockwork control joints, precast concrete panel joints and cladding panel joints alike. For commercial sealant work in Shirley, you deal with one contact from quote to sign-off, whether it’s one building or several.

Around Shirley, most floor and movement joint jobs are single buildings or yards. Getting widths, depths and traffic details up front means one visit, not two.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

What the job involves on each surface

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.

Brickwork and blockwork joints

Long brick and block elevations have movement joints at intervals. They take a low-modulus sealant with a movement class to suit laid over backing rod at the correct depth.

How a job runs

At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Work in places the size of Shirley is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

What we need from you

  • Agree which areas must stay open
  • Warn occupants and staff about the work
  • Share the asbestos register for older buildings

What sealant work can’t fix

We check first that sealant really is the fix. It won’t put right:

  • Proprietary pre-formed expansion joint systems
  • Waterproofing layers buried beneath the sealant
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Surfaces we seal

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

Why deal with it now?

Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up. Resealing early keeps the work to sealant. Small buildings around Shirley suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

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

What you get with us

  • 12-month guarantee on workmanship
  • Public liability insurance in place
  • CSCS-carded applicators
  • Failed material removed, not covered up

For managing agents and facilities managers

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Shirley can form part of a wider programme across Southampton.

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

When to bring in a specialist

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.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Floors, slabs and movement joints in Shirley

Shirley sits close to the coast, within about 1 mile. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, which is why split joints are worth sealing before the edges deteriorate. Shirley sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint.

Campuses like University of Southampton (to the east of Shirley) mix old and new buildings, with movement joints wherever they meet. On industrial estates such as Liners Industrial Estate (0.7 miles south of Shirley), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Across sites such as Shirley Retail Park, 0.7 miles north-east of Shirley, floor and movement joints can be sealed in phases so units keep working.

Shirley is about 2 miles west of Southampton, in Southampton. Any commercial site in Shirley is covered, whether it’s a single job or part of a planned programme. 30 places across Southampton fall within our area, including Shirley.

Questions about Shirley

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

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Is Shirley too far out for you?

Not at all. Shirley is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Does the weather affect joint sealing?

Weather matters for any external joint. Internal floor joints are far less affected.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Can a joint be sealed if the edges are broken?

Spalled edges need repairing before a new seal will last and we’ll flag every length affected. A bead on a broken edge soon lets go.
