How the job changes by surface

Car park decks and ramps

Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again flagging broken edges along the way.

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves.

Expansion joint sealing in Dunkeld

Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels. If the arrises are already broken, we will say so before sealing, and phased work keeps areas in use. If you have spalled or broken joint edges in floors and decks and damp inside where a wall movement joint has failed, we can put it right, on blockwork control joints, podiums and floor movement joints and precast concrete panel joints alike. Whoever orders the work in Dunkeld, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

For outside joints near Dunkeld, the Scottish weather sets the timetable: sealant needs a dry joint and a temperature within its range. Inside slabs aren’t affected and can be scheduled around the occupier.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Common problems we fix in Dunkeld

When the movement exceeds the sealant’s capability, the bead tears. Cohesive failure, a split through the centre, typically means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again unless width and product are reviewed.

Clients normally get in touch after noticing something like this:

  • Expansion joints split through the centre of the bead
  • Car park joints leaking onto vehicles below
  • Brittle, chalky sealant on external joints
  • Chipped joint edges on forklift routes

Warehouse floors on estates like Cally Industrial Estate (to the north of Dunkeld) carry pallet trucks and forklifts over every saw-cut joint.

Questions to ask before you book

  • Who will actually carry out the work
  • Whether old or failed sealant will be cut out, not overlaid
  • Is the sealant right for the movement and the substrate?
  • Their plan for phasing and protecting the area

Our contractor checklist

Aftercare for building managers

To get the most from the new sealant:

  • Clear dirt from joint lines during routine cleaning
  • Inspect exposed joints once the cold weather has passed
  • Brief car park operatives to protect joint lines during winter clearance
  • Note which joints were done, when, and with what

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal.

An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load, turning a sealant job into a repair job. A sound seal keeps the joint working.

Diagnose, treat, sign off

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For work around Dunkeld, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

What we need from you

  • Tell us which areas need to stay in use
  • Send asbestos survey details if the building is pre-2000

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Induction, permit and paperwork requirements
  • The size and state of each joint
  • Access and working height
  • Which sealant the job calls for

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What to include in your enquiry

Good information means a firmer quote. When you get in touch, include:

  • The postcode of the building
  • The type of building and who uses it
  • Anything awkward about access or site hours
  • Approximate linear metres or a joint schedule

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or send details through our quote form with what you know.

What happens if it’s left?

Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed and we will tell you honestly. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Dunkeld before they leak.

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

What you get with us

Across sites such as Birnam Industrial Estate, which lies south-east of Dunkeld, floor and movement joints can be sealed in phases so units keep working.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

What happens if it rains on the day?

Outside work depends on conditions. Indoor joints can normally carry on regardless.

Do you offer coloured sealant?

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 will confirm the colours available for the specified product.

How much does the work cost?

There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.

What’s the difference between an expansion joint and a movement joint?

The general name is movement joint, and expansion joint is one common type. In everyday use the two names are often swapped and the way they’re sealed is similar.
