Expansion joint sealing for commercial buildings in Auchenheath

Internal floor joints take trolleys, pallet trucks and forklifts. Without a sound filler, joint edges chip and spall under load, so the right filler or sealant for the traffic and movement matters. If the arrises are already broken, we will say so before sealing, and phased work keeps areas in use. The enquiries we see most involve leaks through car park deck joints onto the level below and weathered movement joint sealant that no longer flexes, on car park decks and ramps, precast concrete panel joints and brickwork movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Auchenheath, preparation and product choice get the time they need.

Weather windows decide external joint work around a place like Auchenheath: sealant needs a dry joint and a temperature within its range. 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. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Maintenance after handover

Once the work is signed off, these steps help:

  • Inspect exposed joints once the cold weather has passed
  • Report split or peeling joint sealant early
  • Brief car park operatives to protect joint lines during winter clearance
  • Note which joints were done, when, and with what

Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check. Should you spot a problem, you can phone 01277 525 020 or email drawings and photos and send a picture.

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. Sealing the joint promptly stops it at source.

Your questions answered

Must our site in Auchenheath stop work while the joints are done?

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.

Is hospital work, at somewhere like Birkwood Castle, something you do?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Can you work on car park ramps and decks?

Yes. We use a sealant designed for wheel loads and the expected movement.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Should maintenance staff do it?

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

A short, simple internal joint is often within reach of a maintenance team. 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.

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • A joint that has to be widened or re-detailed before it can work
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Damaged metal nosings or cover plates over a joint

If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

What we seal

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

What the job involves on each surface

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.

Cladding panel joints

We confirm what access is in place before pricing. Close-up photographs help us judge the joints, or we visit if they don’t show enough.

Common problems we fix in Auchenheath

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’s common on joints sealed in a hurry.

It’s worth sending us details if you spot any of the following:

  • Chipped joint edges on forklift routes
  • Car park joints leaking onto vehicles below
  • Torn sealant in brick or block movement joints
  • Expansion joints filled with dirt and stones

Schools like Lesmahagow High School often have long brick elevations with movement joints that age quietly.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • How joint depth will be controlled
  • Which product they’ll use, and why it suits the joint
  • How the existing material will be dealt with

How to choose a sealant contractor

From enquiry to sign-off

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Tell us who will meet us and how to get in at your building near Auchenheath. That goes into the plan alongside the quote.

  1. We look at the joints, their width and how they’ve failed.
  2. You get a fixed quote with the product and its movement capability stated.
  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. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

What we need from you

  • Let building users know which areas are affected
  • Tell us which areas need to stay in use
  • Point out parking and an unloading spot
