Expansion joint sealing for Caol sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What we can’t put right

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:

  • Cracking or settlement that calls for an engineer’s assessment
  • Joints too narrow for the movement, which need redesigning by the engineer
  • Broken or spalled joint edges, which need repairing before any sealant goes in

If in doubt, call the office on 01277 525 020 or email us and we will say what we think.

Surfaces we seal

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

About our expansion joint sealing in Caol

Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. Site teams most often ask us about water dripping through deck or ramp joints and joints packed with grit and debris, on precast concrete panel joints, car park decks and ramps and blockwork control joints. For commercial sealant work in Caol, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Around smaller Scottish places like Caol, slabs needing attention are often in agricultural buildings, workshops, schools and hotels. Concrete slabs and yards there take vehicles and weather.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

What happens if it’s left?

Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now because damage continues. Urgent joints now, the rest later, is often the sensible plan. For buildings near Caol, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Doing it in-house

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Inspect movement joints alongside other routine building checks
  • Record the sealant used and the date in the O&M file
  • Inspect exposed joints once the cold weather has passed

Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it and decks and floors suffer most. A routine sweep is the simplest protection.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall. Keeping the seal sound avoids all of that.

FAQs: Caol

Is Caol 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. Good photos up front let us bring everything on the first visit.

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

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Why do our movement joints keep failing?

The way it has failed normally tells us why: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Broken edges are a third possibility.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Can the building stay open while you work?

Usually, yes. We phase the work so most of the building stays in use.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Travel to smaller Scottish places like Caol is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. First the joints are inspected, widths measured and the type of failure noted.
  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. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Getting the site ready

  • Agree which areas must stay open
  • Tell staff and tenants when we will be in
  • Tell us what induction or permit system the site runs

Warehouse floors and decks around Caol

With the shore within about 2 miles, Caol counts as a coastal location. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner. The west of Scotland, where Caol is, gets more rain than the east. Rainwater through open yard and deck joints is a bigger issue here than in the drier east. Outside joints are sealed in dry spells, so dates have some give.

Another example is Fort William Retail Park, 1 mile to the south-east of Caol, where floors and yards would be done in stages around the occupiers. On industrial estates such as Blar Mhor Industrial Estate, which lies east of Caol, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Large sites such as Belford Hospital, 1.3 miles south of Caol, have car parks, service roads and long elevations with movement joints in brick and panels.

Caol is in Highland. If you’re looking for expansion joint sealing in Caol, we can help, as we do across Highland. Across Highland, 256 places are covered, Caol among them. Glasgow is covered too, around 75 miles from Caol.
