Expansion joint sealing for Elderslie sites

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

Common problems we fix in Elderslie

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens, which is why depth control matters.

Look out for the following:

  • Leaks through car park deck joints onto the level below
  • Hardened, cracked sealant on exposed facades
  • Joints packed with grit and debris
  • Water getting into the wall through a failed joint

Parks like St James Business Centre (to the north of Elderslie) combine paved areas, car parks and building elevations, each with joints that move.

Questions to ask before you book

  • The named product and why it was chosen
  • How they handle RAMS and site documents
  • How the joint faces will be prepared and primed
  • Will CSCS-carded applicators be on site?

About our expansion joint sealing in Elderslie

Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap. We reseal deck and ramp joints with a trafficable sealant chosen for the movement. We work on precast concrete panel joints, cladding panel joints and car park decks and ramps, and the failures we are asked to look at most are sealant peeling off one face of the joint and expansion joints split through the centre of the bead. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Elderslie is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

On site: what to expect

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Jobs near Elderslie are often grouped with others in the same area. Tell us how flexible your dates are.

  1. We start with photographs, 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. Old sealant and debris are cut out of every joint.
  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. Areas reopen once cured, and the work carries our 12-month guarantee.

Getting the site ready

  • Tell us which areas need to stay in use
  • Arrange parking or a loading space

Advice

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Damaged metal nosings or cover plates over a joint
  • Waterproofing layers buried beneath the sealant
  • Movement on a scale no sealant is meant to absorb

If you’re not sure, just give us a call on 01277 525 020 or email the details over and we will give you a straight answer.

What we seal

  • Blockwork control joints
  • Podiums and floor movement joints

Expansion joint sealing in Elderslie: the local picture

Elderslie is in the west of Scotland, the wetter side of the country. Open joints in external slabs take a lot of water. We wait for dry, workable days to seal them. Less than 3 miles from Elderslie 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.

Schools like Gleniffer High School often have long brick elevations with movement joints that age quietly. Hospitals like Royal Alexandra Hospital, 2.1 miles east of Elderslie, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Elderslie is about 1 mile east of Johnstone, in Renfrewshire. Commercial clients in Elderslie can call on us for movement joints. We work across 23 places in Renfrewshire. We also cover Glasgow, some 8 miles away.

Owners, agents and contractors

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

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. Keys, access and contacts can be agreed in advance.

Surface by surface

Podium joints

Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix.

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen, and we will confirm the colours available for the specified product.

FAQs: Elderslie

Do you take on work at healthcare sites like Royal Alexandra Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Is Elderslie too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across every Scottish council area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Are you CHAS accredited?

Yes. We’re CHAS accredited and a Constructionline member.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Which product is best for expansion joints?

The right product depends on the joint. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints unless the specification names something else.

What exactly is a movement joint?

The terms overlap a great deal. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.

Leave it or put it right?

A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed, and we will say so before quoting. Around smaller places like Elderslie, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Resealing early avoids that.

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