Expansion joint sealing in the Scottish Borders: how it works

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side. A sealant suited to traffic and the expected movement goes in and the work can be phased so parts of the car park stay open. We work on brickwork movement joints, car park decks and ramps and blockwork control joints, and the failures we are asked to look at most are rain penetration at brick or block movement joints and spalled or broken joint edges in floors and decks.

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it.

First, the joints are inspected for width, movement and the type of failure.
You get a fixed quote with the product and its movement capability stated.
Old sealant and filler are cut out and the joint faces cleaned back to sound material.
Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
We check every joint before sign-off, and the work carries our 12-month guarantee.

Around Galashiels

Locally, jobs take us to sites close to Galashiels, Public House and Galashiels Academy. There’s a railway station in Galashiels itself: Galashiels station. Well-known places in the area include Borders General Hospital (2.7 miles south-east) and Castle Holydean (4.4 miles south-east). Green spaces nearby include Eildon Mid Hill.

Floors, slabs and movement joints across the Scottish Borders

Most floor and movement joint work across the Scottish Borders has to happen while sites keep operating, so we work in phases and hand areas back as they cure.

Work in the Scottish Borders comes under Scotland’s own building standards and technical handbooks. Our part is sealing to the specification, whatever the building. Coastal places in the Scottish Borders often have hotels, guest houses and holiday accommodation with busy seasons, so work is often best planned for quieter months.

Galashiels: Hospital campuses such as Borders General Hospital, 2.7 miles south-east of Galashiels, grow in stages, leaving movement joints wherever new blocks meet old. Warehouse floors on estates like Netherdale Industrial Estate (to the south-east of Galashiels) carry pallet trucks and forklifts over every saw-cut joint.

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
Leaks coming from the membrane rather than the joint seal
A joint that has to be widened or re-detailed before it can work

Aftercare for building managers

Regular inspection catches problems early. In particular:

Clear dirt from joint lines during routine cleaning
Leave barriers in place until fresh joint sealant has cured
Record the sealant used and the date in the O&M file
Act on the first tear or lifting edge rather than waiting

Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.

A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Resealing early limits the damage.

Should maintenance staff do it?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Why it fails

Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons and it often shows on rushed work.

Things that normally lead to an enquiry:

Brittle, chalky sealant on external joints
Debris jammed in movement joints
Joints where the bead has lost adhesion
Torn sealant in brick or block movement joints

What affects the price in the Scottish Borders

There’s no standard rate for sealant work, because every site is different. What we look at:

Specialist products, such as fire-rated or hygienic sealants
Any access equipment needed
How much there is to seal
Backing rod, priming and other preparation

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

What to include in your enquiry

The more we know, the firmer the quote. Helpful details to send:

Whether an asbestos survey exists
Photos of the joints, close up and from further back
When you need the work done
The postcode of the building

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or use the quote form.

Common questions from the Scottish Borders clients

Do the joint edges need to be sound before sealing?

Broken arrises have to be put right before resealing. A bead on a broken edge soon lets go.

Why do our movement joints keep failing?

The way it has failed usually tells us why: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Sometimes the edge material itself has failed.

What guarantee do you give on joint sealing?

Our workmanship on movement joints carries a 12-month guarantee. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.

How long does movement joint sealing take?

It normally takes 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. Cure time before reopening is confirmed on the day.

Can the sealant be colour-matched?

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’ll confirm the colours available for the specified product.

What exactly is a movement joint?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint.

Do you use silicone or polyurethane in movement joints?

Movement capability matters most. Hybrid or MS polymer products suit some mixed-material joints.
