Expansion joint sealing for Stor sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Common problems we fix in Stor

Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens, which is why depth control matters.

Things that typically lead to an enquiry:

  • New sealant over old, now failing
  • Car park joints leaking onto vehicles below
  • Joints packed with grit and debris
  • Rain penetration at brick or block movement joints

A joint near Stor that has lost its sealant lets in water and grit, and the edges suffer next; we will tell you if the edges need repairing first.

What your quote should include

  • Will RAMS and insurance details be available?
  • Are they CHAS accredited or on Constructionline?
  • Their public liability cover
  • Is the sealant right for the movement and the substrate?

Choosing a commercial sealant contractor

Expansion joint sealing in Stor, done properly

Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. If you have spalled or broken joint edges in floors and decks and weathered movement joint sealant that no longer flexes, we can put it right, on podiums and floor movement joints, blockwork control joints and brickwork movement joints alike. One point of contact handles commercial sealant work in Stor from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Around smaller Scottish places like Stor, slabs needing attention are often in agricultural buildings, workshops, schools and hotels. Slabs and yards take vehicles, rain and frost.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Maintenance after handover

Once the work is signed off, these steps help:

  • Clear dirt from joint lines during routine cleaning
  • Look over external and deck joints after a hard winter
  • Report split or peeling joint sealant early
  • Put movement joints on the planned maintenance inspection round

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. Should you spot a problem, you can call 01277 525 020 or send photos by email and send a picture.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Sealing early protects the edges.

Joints that move: notes for Stor

The sea is no more than about 1 mile from Stor. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so it pays to keep them sealed. Stor is on Scotland’s wetter western side. External slab joints left open take plenty of rain. Dry spells are used for the external joints.

Around Stor, each joint gets a filler or sealant matched to what crosses it and how much it moves.

Stor (Gaelic: Stoer) is in Highland. Any commercial site in Stor is covered. Our Highland coverage takes in 256 places.

Postcode districts covered here: IV27 for movement joints. Nearby places we also cover include Stoer (1 mile south-west), Lochinver (5 miles south-east), An Druim Beag (5 miles north-east), Scourie More (11 miles north-east) and Scourie (12 miles north-east). Where a site is remote or on an island, travel and materials need planning ahead, so include the location in your enquiry.

Different surfaces, different methods

Joints between different materials

Junctions between brick and render, or concrete and cladding, move independently. The product must bond to both substrates and cope with the movement, with primer where specified.

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.

Doing it in-house

Site maintenance staff can often handle a short internal joint. 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.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

How a job runs

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Travel to smaller Scottish places like Stor is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.

  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.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  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.

Before we start on site

  • Send your site hours and access windows
  • Agree which areas must stay open
  • Tell staff and tenants when we’ll be in

Your questions answered

Does the sea air around Stor change the choice of sealant?

It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Is a smaller place like Stor outside your area?

Not at all. Stor is within our area. Every Scottish council area is within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

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

It’s a deliberate gap that lets the structure move without cracking. Many people call it an expansion joint.

What sealant do you use in movement joints?

Movement capability matters most. Where two different materials meet, a hybrid sealant can be the better choice.

Are you CHAS accredited?

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

Can you quote from photographs?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

What we can’t put right

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Damaged metal nosings or cover plates over a joint

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