Expansion joint sealing across Oxnam

Expansion joint sealing in Oxnam

Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied. The enquiries we see most involve weathered movement joint sealant that no longer flexes and car park joints leaking onto vehicles below, across cladding panel joints, car park decks and ramps and precast concrete panel joints. A single leaking joint is often how a building in Oxnam first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller Scottish places like Oxnam, slabs needing attention are often in agricultural buildings, workshops, schools and hotels. Slabs and yards take vehicles, rain and frost.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Our process

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Oxnam, we aim for one trip, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.

  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. Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

Advice

Why deal with it now?

Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s usually not far behind. We can price a patch and a full reseal side by side. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Resealing early avoids that.

The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote when you are ready.

Maintenance after handover

Once the work is signed off, these steps help:

  • Note which joints were done, when, and with what
  • Keep traffic off new joints until the cure time is up
  • Treat a small split as a warning, not a cosmetic issue
  • Keep stones and debris out of open joint lines

On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead, and it’s worth checking joints once the cold weather has passed.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster. Keeping the filler or sealant sound protects the floor.

Work for main contractors and building owners

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

How the job changes by surface

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability.

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them, and tell you if edges need repairing first.

Where floor joints take the most wear near Oxnam

The east of Scotland, where Oxnam is, gets less rain than the west. Frost and winter road salt still work into open joints in car parks and yards. Sealing them before winter limits the damage.

In and around Oxnam, the right filler or sealant for each joint depends on the traffic and the movement it takes. On industrial estates such as Oxnam Road Industrial Estate (2.6 miles north-west of Oxnam), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

Your questions answered

Is Oxnam Road Industrial Estate, near Oxnam, within your area?

Yes. Our area takes in Oxnam and its surroundings, with estates and business parks such as Oxnam Road Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.

Must our site in Oxnam stop work while the joints are done?

Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we will plan from there.

Can a joint be sealed if the edges are broken?

Sealant needs sound faces to bond to, so we will tell you if the edges need repairing before sealing. Where it’s visible beforehand, we will say so when we quote.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

What exactly is a movement joint?

It’s a deliberate gap that lets the structure move without cracking. Many people call it an expansion joint, and either way it needs a sound seal.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
