About our expansion joint sealing in Brae

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water, the joint can’t close properly and its edges begin to crumble. Resealing at the first signs of failure is far cheaper than repairing the material either side. The enquiries we see most involve weathered movement joint sealant that no longer flexes and expansion joints filled with dirt and stones, on brickwork movement joints, podiums and floor movement joints and car park decks and ramps. Most enquiries from Brae start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

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

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Questions about Brae

Do you work on the island where Brae is?

Yes, Brae is within the area we cover. We work across every Scottish council area. Ferry times and the weather set the plan, so we ask for photographs and a full list first.

Does the sea air around Brae change the choice of sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards.

How long does movement joint sealing take?

Expect a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, with phasing where areas must stay open. We’ll confirm when each area can be used again.

Can you work while the building is occupied?

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

Is colour matching possible?

That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What the job involves on each surface

Car park decks and ramps

Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed, and we will tell you if any edges need repairing first.

Brickwork and blockwork joints

Mortar snots and debris in the joint stop it working. Everything is raked out before backing and sealant go in.

Expansion joint sealing around Brae: how the place shapes the job

With the shore within about 1 mile, Brae counts as a coastal location. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so a failed joint lets more in and the edges break up sooner. Work on Brae has to fit the ferry timetable and the forecast. Send joint sizes and details of the traffic so the right materials come on the crossing.

For floors and slabs around Brae, the product is chosen for the traffic and the movement at each joint. Around Brae, open joints collect water and debris, and the arrises are the next to go.

Brae is in the Shetland Islands. Any commercial site in Brae is covered, whether it’s a single job or part of a planned programme. Brae is one of 63 places we cover in the Shetland Islands for movement joints.

Business premises anywhere in ZE2 are within our area. If your site is on Runafirth, Ladieside and Hevdaland or close by, we can quote for movement joints. Close to Brae, our area also takes in Sullom (3 miles north), Scatsta (3 miles north-east), Voe (4 miles south-east), Firth (6 miles north-east) and Hogaland (7 miles north). Brae ranks among the main centres of the Shetland Islands, with offices, shops, schools and other public and commercial buildings. Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you ring 01277 525 020 or use the quote form.

Why act early in Brae

A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. We’ll flag where edges need repair before sealing. Around smaller places like Brae, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Early resealing prevents it.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why appoint us

  • Specification-led, product-correct work
  • Standard and matched colours in many product ranges
  • Matching to RAL references, product permitting
  • One phone line for London, the South East and Scotland

From enquiry to sign-off

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Tell us who will meet us and how to get in at your building near Brae. We will confirm the plan with the fixed quote.

  1. We look at the joints, their width and how they’ve failed.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  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.

What we need from you

  • For older buildings, check the asbestos register before work
  • Tell staff and tenants when we will be in
  • Move anything stored against the joints

Advice

Aftercare for building managers

Regular inspection catches problems early. In particular:

  • Keep scrapers and ploughs from dragging across joint sealant
  • Inspect movement joints alongside other routine building checks
  • Keep product details with the building records for the next reseal
  • Keep stones and debris out of open joint lines

Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in. If anything looks wrong, speak to us on 01277 525 020 or email us with photographs.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.
