Expansion joint sealing in Cullivoe

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels so the product has to suit both the traffic and the movement. If the arrises are already broken, we’ll say so before sealing, and phased work keeps areas in use. Site teams most often ask us about arrises breaking up along floor joints and car park joints leaking onto vehicles below, on brickwork movement joints, precast concrete panel joints and podiums and floor movement joints. One point of contact handles commercial sealant work in Cullivoe from the first photos to the final walk-round, for single jobs and planned programmes alike.

Weather windows decide external joint work around a place like Cullivoe: sealant needs a dry joint and a temperature within its range, so dates have some give. Internal floors can be done whenever suits the site.

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.

What the job involves on each surface

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them, and tell you if edges need repairing first.

Car park decks and ramps

Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again, and we’ll tell you if any edges need repairing first.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Where we can, we combine work around Cullivoe with other jobs nearby. Tell us how flexible your dates are.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, 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. 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

Owners, agents and contractors

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

FAQs: Cullivoe

Will you travel to Cullivoe on the island?

Yes. We work across every Scottish council area, and that includes island locations such as Cullivoe. We group island work where we can and plan around the crossings.

Does a site in Cullivoe have to shut while its joints are sealed?

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.

What exactly is a movement joint?

Movement joint is the broad term for any joint built in to let a structure move. In everyday use the two names are often swapped, and the sealing method is much the same.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

Can a joint be sealed if the edges are broken?

Sealant needs sound faces to bond to, so broken or crumbling edges have to be repaired first. We flag it at the quote stage where we can see it.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

What happens if it’s left?

Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach, and we’ll say so before quoting. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Cullivoe before they leak.

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What we are called out for in Cullivoe

Sealant peeling cleanly off one side is an adhesion failure. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes.

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

  • New sealant over old, now failing
  • Brittle, chalky sealant on external joints
  • Expansion joints split through the centre of the bead
  • Car park joints leaking onto vehicles below

In and around Cullivoe, the right filler or sealant for each joint depends on the traffic and the movement it takes.

Choosing a commercial sealant contractor

Traffic, movement and joints around Cullivoe

The sea is no more than about 1 mile from Cullivoe. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so a failed joint lets more in and the edges break up sooner. Being in the east of Scotland, Cullivoe gets less rain than the west coast. Cold winters and gritting are hard on any yard or deck joint left open. Autumn is a sensible time to seal them.

Around Cullivoe, open joints collect water and debris, and the arrises are the next to go.

Cullivoe is in the Shetland Islands. We send applicators to Cullivoe for movement joints. Across the Shetland Islands, 63 places are covered, Cullivoe among them.

Anyone looking for expansion joint sealing in ZE2 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. Access to Cullivoe is via the B9083 among other routes. Just outside Cullivoe, we also work in Clivocast (4 miles south-east), Baltasound (6 miles north-east), Camb (7 miles south), Mid Yell (8 miles south) and Haroldswick (9 miles north-east). Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.
