Expansion joint sealing in Innerleithen

Few joints take as much punishment as those in a car park. Tyres load the edges, and de-icing salts and water work into any gap. A sealant suited to traffic and the expected movement goes in. Most enquiries involve joints where the bead has lost adhesion and previous reseals laid over old sealant, on car park decks and ramps, podiums and floor movement joints and cladding panel joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Innerleithen it comes down to the same thing: the right product in a properly prepared joint.

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

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Commercial clients in Innerleithen

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.

Common problems we fix in Innerleithen

Some joints were never sealed with the right product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.

If one of these sounds familiar, it’s time for a closer look:

  • Water dripping through deck or ramp joints
  • Damp inside where a wall movement joint has failed
  • Sealant peeling off one face of the joint
  • Movement joints with split or torn sealant

A healthcare site such as Hay Lodge Hospital (to the west of Innerleithen) depends on car parks, ramps and service yards whose joints take traffic all day.

Before you book anyone

  • Health and safety accreditation such as CHAS
  • Whether primer will be used where the manufacturer specifies it
  • Which product they’ll use, and why it suits the joint
  • Whether their applicators hold CSCS cards

Our contractor checklist

Diagnose, treat, sign off

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. Where we can, we combine work around Innerleithen with other jobs nearby. Let us know if your dates have any give.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  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

  • Share the asbestos register for older buildings
  • Tell staff and tenants when we’ll be in
  • Clear stock, furniture or equipment away from the joints

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Common questions from Innerleithen clients

Do we have to stop operations in Innerleithen while the joints are sealed?

Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.

Is Innerleithen off your patch?

No. Places such as Innerleithen are covered as much as the big towns. Our area covers all of Scotland, cities, towns and islands alike. Good photos up front let us bring everything on the first visit.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Are you CHAS accredited?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Will you just go over the old sealant?

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

What if the joint edges are damaged?

Broken arrises have to be put right before resealing, and we will point out where that’s the case. Sealing over them leads to early failure.

What’s the quickest route to a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

What we can’t put right

Honesty saves time and money. New sealant won’t cure:

  • A joint that has to be widened or re-detailed before it can work
  • Crumbling edges that would give a new bead nothing sound to grip
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

If you are not sure, just call the office on 01277 525 020 or use the quote form and we’ll give you a straight answer.

Joints and surfaces we work on

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

How the job changes by surface

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen.

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix and flag it if the membrane looks like the source.

Slabs, ramps and loading bays in Innerleithen

Innerleithen is on Scotland’s drier eastern side. Frost and de-icing salt still find their way into open external joints. Resealing before the cold months helps protect the edges.

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