Expansion joint sealing for Dalmuir sites

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

Expansion joint sealing for commercial buildings in Dalmuir

Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. We reseal deck and ramp joints with a trafficable sealant chosen for the movement, phasing bays so the car park can stay in use. The enquiries we see most involve leaks through car park deck joints onto the level below and damp inside where a wall movement joint has failed, across brickwork movement joints, blockwork control joints and precast concrete panel joints. One point of contact handles commercial sealant work in Dalmuir from the first photos to the final walk-round, whether it’s one building or several.

For floor or movement joints around smaller places like Dalmuir, we plan to finish in one visit where we can. Send photos, joint widths and details of the traffic first.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Dalmuir: questions and answers

Does a coastal location like Dalmuir affect which sealant is used?

It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.

Is Dalmuir off your patch?

Not at all: smaller places are covered as well as towns. Every Scottish council area is within our area. Good photos up front let us bring everything on the first visit.

What about RAMS and site documents?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Can the building stay open while you work?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

When it isn’t the sealant

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:

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Changing the joint layout or spacing of a structure
  • Proprietary pre-formed expansion joint systems

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we will tell you honestly.

Joints and surfaces we work on

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

Different surfaces, different methods

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix.

Cladding panel joints

We confirm what access is in place before pricing. Close-up photographs help us judge the joints.

Doing it in-house

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Signs you need expansion joint sealing in Dalmuir

Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way, so we check width and movement before quoting.

Site and facilities staff are often the first to spot these:

  • Joints packed with grit and debris
  • Water dripping through deck or ramp joints
  • Arrises breaking up along floor joints
  • Damp inside where a wall movement joint has failed

Campuses like University of Glasgow Garscube Campus, 4.7 miles to the east of Dalmuir, mix old and new buildings, with movement joints wherever they meet.

What to look for in a quote

  • Are they CHAS accredited or on Constructionline?
  • How long is the guarantee, and what does it include?
  • How joint depth will be controlled
  • Will RAMS and insurance details be available?

Choosing a commercial sealant contractor

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Tell us who will meet us and how to get in at your building near Dalmuir. We’ll confirm the plan with the fixed quote.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Getting the site ready

  • Tell us which areas need to stay in use
  • Send your site hours and access windows

Where floor joints take the most wear near Dalmuir

Dalmuir is within about 3 miles of the coast. Open joints in coastal car parks and yards let in salt-laden water as well as grit, which is why split joints are worth sealing before the edges deteriorate. Dalmuir has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

Hospital campuses such as Golden Jubilee National Hospital, under half a mile to the south-east of Dalmuir, grow in stages, leaving movement joints wherever new blocks meet old. Another example is Bridgewater Shopping Centre, 0.6 miles south-west of Dalmuir, where floors and yards would be done in stages around the occupiers.

Looking after the joints

Once the work is signed off, a little attention goes a long way:

  • Keep racking legs and heavy point loads off floor joints
  • Treat a small split as a warning, not a cosmetic issue
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Reopen bays and walkways only after the stated cure time

Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file, so the next reseal starts with the facts.

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