How we handle expansion joint sealing in Cronberry

Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels so the product has to suit both the traffic and the movement. We will tell you if the edges need repairing before sealing. 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 damp inside where a wall movement joint has failed and expansion joints filled with dirt and stones. A specialist sealant contractor works differently from a general builder: in Cronberry, that means joint design, primers and backing rod as standard.

For outside joints near Cronberry, the Scottish weather sets the timetable: dry faces and the right temperature are essential. Inside slabs aren’t affected and can be scheduled around the occupier.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Clear dirt from joint lines during routine cleaning
  • Note which joints were done, when, and with what
  • Avoid parking heavy plant or pallets on joint lines
  • Keep scrapers and ploughs from dragging across joint sealant

Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint and we’ll tell you when each bay or area can reopen. Barriers left in place until then protect the finish.

Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one, so the work can be planned rather than rushed. We’ll tell you which movement joints need doing now and which can wait.

For managing agents and facilities managers

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

What the job involves on each surface

Joints between different materials

Some mixed-material joints suit a hybrid sealant. We pick the product for the materials and the movement.

Brickwork and blockwork joints

Vertical movement joints in brick and block walls let the masonry grow and shrink. We use a sealant rated for the movement, typically low-modulus, with backing rod setting the depth.

Traffic, movement and joints around Cronberry

Cronberry is in the west of Scotland, the wetter side of the country. Open joints in car parks and yards let in more water than in drier areas. Outside joints are sealed in dry spells, so dates have some give.

If you manage units on an estate such as Thistle Industrial Estate, 2.9 miles south-west of Cronberry, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.

Cronberry is about 14 miles south-east of Kilmarnock, in East Ayrshire. We send applicators to Cronberry for movement joints, handled exactly as we handle every other area. We work across 56 places in East Ayrshire. For work in that direction, see our Glasgow page.

Postcode districts covered here: KA18 for movement joints. If your building is just outside Cronberry, we cover Lugar (1 mile south-west), Logan (2 miles south-west), Craigens (3 miles south-west), Cumnock (3 miles south-west) and The Rigg (3 miles west). Bigger towns within reach include Kilmarnock (14 miles north-west), Annanhill (15 miles north-west), Galston (11 miles north-west), Mauchline (7 miles west), New Farm Loch (14 miles north-west) and Bonnyton (15 miles north-west).

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Where we can, we combine work around Cronberry with other jobs nearby. Let us know if your dates have any give.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Finished joints are checked and backed by our 12-month guarantee.

Getting the site ready

  • Explain the parking and delivery arrangements
  • Let building users know which areas are affected
  • Have the specification and drawings to hand

Advice

Common problems we fix in Cronberry

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. The same product in the same joint tends to fail again unless width and product are reviewed.

Common reasons buildings call us in:

  • Water dripping through deck or ramp joints
  • Damp inside where a wall movement joint has failed
  • Arrises breaking up along floor joints
  • Expansion joints split through the centre of the bead

Large sites such as East Ayrshire Community Hospital, 3.1 miles to the south-west of Cronberry, have car parks, service roads and long elevations with movement joints in brick and panels.

What your quote should include

  • What level of public liability insurance do they hold?
  • How long is the guarantee, and what does it include?
  • Which product they’ll use, and why it suits the joint
  • Whether primer will be used where the manufacturer specifies it

Questions about Cronberry

Is a smaller place like Cronberry outside your area?

No. Small places get the same service as large ones. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.

Does your area include sites such as Thistle Industrial Estate, near Cronberry?

Yes. We cover Cronberry and the area around it, including industrial estates, business parks and retail parks such as Thistle Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.

When can you be on site?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

What if the joint edges are damaged?

Sound edges are essential. If they’re damaged, we’ll say so before any sealing so you are not paying for a bead that won’t hold.

Is it fine to apply new sealant on top of old?

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

General trades versus a specialist

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
