Keeping the joints sound

After handover, these steps help:

  • Act on the first tear or lifting edge rather than waiting
  • Avoid parking heavy plant or pallets on joint lines
  • Keep stones and debris out of open joint lines
  • Keep scrapers and ploughs from dragging across joint sealant

Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in. Should you spot a problem, you can give us a call on 01277 525 020 or send photos by email and send a picture.

Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. A sound seal keeps the joint working.

Expansion joint sealing for commercial buildings in Blackness

Brickwork and blockwork walls have vertical movement joints at intervals that most people only notice when the sealant has gone. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. We work on car park decks and ramps, brickwork movement joints and precast concrete panel joints, and what we are called in for most is torn sealant in brick or block movement joints and sealant peeling off one face of the joint. Whoever orders the work in Blackness, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In Scotland’s cities, buildings from car parks and malls to university and hospital estates rely on movement joints. Failed joints let water in, and repeated frost then works on the edges.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Questions we’re asked in Blackness

Our building in Blackness is near the coast: does that change the sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Would you work within a site like Royal Victoria Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Can a joint be sealed if the edges are broken?

The edges have to be sound. Where they’ve broken up, we will tell you they need repairing first so you’re not paying for a bead that won’t hold.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

What do you charge?

Every job gets its own fixed quote. To get one, call 01277 525 020 or email the details over with a description of the work.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards.

Cost factors for movement joints

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • How much existing material needs removing
  • Joint width, depth and condition
  • Site requirements such as inductions and permits
  • Specialist products, such as fire-rated or hygienic sealants

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Details that help us quote

There’s no need for a formal survey. A few details are enough to get going:

  • The site address and postcode
  • The asbestos register, for older buildings
  • Your programme or deadline
  • Drawings or a marked-up plan, if available

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

From enquiry to sign-off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For premises in Blackness, tell us about access times, shared entrances and any building rules, so the work can be phased and areas kept in use.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Preparing the site

  • Tell us which areas need to stay in use
  • Tell staff and tenants when we will be in
  • Share your working hours and any access restrictions

Ask for a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or send details through our quote form.

Advice

Surface by surface

Podium joints

Podiums take foot traffic, planters and weather. A sealant suited to both traffic and exposure is used.

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.

Floors, slabs and movement joints in Blackness

Blackness lies within about 1 mile of the sea. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so it pays to keep them sealed. Blackness is on Scotland’s drier eastern side. Frost and winter road salt still work into open joints in car parks and yards. Sealing them before winter limits the damage.

Phasing is what makes joint work possible on busy sites such as Gallagher Retail Park (1.3 miles east of Blackness): one bay, aisle or car park row at a time. If you manage units on an estate such as Mid Wynd Industrial Estate, which lies south-east of Blackness, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. Hospitals like Royal Victoria Hospital (0.8 miles west of Blackness) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Blackness is about 1 mile south-west of Dundee, in Dundee. If you’re looking for expansion joint sealing in Blackness, we can help, as we do across Dundee. Blackness is one of 28 places we cover in Dundee.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Cracking or settlement that calls for an engineer’s assessment
  • Waterproofing layers buried beneath the sealant
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly.

Joints and surfaces we work on

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

When to bring in a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
