Expansion joint sealing for Cross sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Expansion joint sealing for commercial buildings in Cross

Internal floor joints take trolleys, pallet trucks and forklifts. Without a sound filler, joint edges chip and spall under load so the product has to suit both the traffic and the movement. We will tell you if the edges need repairing before sealing. If you have layers of sealant in a movement joint and brittle, chalky sealant on external joints, we can help. A single leaking joint is often how a building in Cross first comes to us: we look at the rest while we are there and tell you what we find.

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

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building near Cross, directions, keys and a contact on the day are worth sorting early. We’ll confirm the plan with the fixed 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. We strip out the old seal and prepare the faces.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Preparing the site

  • Share your working hours and any access restrictions
  • Warn occupants and staff about the work
  • Have the specification and drawings to hand

What we’re called out for in Cross

When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes.

Most enquiries start with one or more of the following:

  • Leaks through car park deck joints onto the level below
  • Movement joints with split or torn sealant
  • Chipped joint edges on forklift routes
  • Joints packed with grit and debris

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

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • Their plan for phasing and protecting the area
  • The named product and why it was chosen
  • What level of public liability insurance do they hold?

Our contractor checklist

For managing agents and facilities managers

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

How the quote is worked out

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Quantities, in metres or numbers
  • Distance, for remote addresses
  • Specialist products, such as fire-rated or hygienic sealants
  • Phasing around occupants

The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote when you are ready.

Details that help us quote

We can often quote from photographs and a few details. Please tell us:

  • What the building is and how it’s used
  • Photos of the joints, close up and from further back
  • The asbestos register, for older buildings
  • Where the site is, with the postcode

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

What we can’t put right

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Damaged metal nosings or cover plates over a joint
  • Changing the joint layout or spacing of a structure
  • Concrete or masonry repairs along the arrises

If in doubt, speak to us on 01277 525 020 or email us and we will say what we think.

Surfaces we seal

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

Traffic, movement and joints around Cross

Cross is within about 2 miles of the coast. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, which is why split joints are worth sealing before the edges deteriorate. Being in the west of Scotland, Cross gets more rain than eastern areas. External slab joints left open take plenty of rain. External sealing is booked for dry spells, with some give in the dates.

A joint near Cross 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.

Cross (Gaelic: Cros) is in Na h-Eileanan Siar. Our applicators travel to Cross for work on movement joints. 87 places across Na h-Eileanan Siar fall within our area, Cross among them.

If you need expansion joint sealing in HS2, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Buildings on Rathad Chros-Sgiogarstaigh, Back Street and New Street are within our area. Just outside Cross, we also work in North Dell (1 mile west), Nis (1 mile east), Ness (1 mile east), Lionel (2 miles north-east) and Lìonal (2 miles north-east). Where a site is remote or on an island, we plan travel and materials carefully.

Near you in Cross

Nearby you will also find Dell Mill (under half a mile west). Not far away are Loch Langavat.

Maintenance after handover

A few simple habits keep the new joints working:

  • Plan racking layouts so feet don’t land on a joint
  • Inspect exposed joints once the cold weather has passed
  • Keep product details with the building records for the next reseal
  • Raise snow-clearing blades over deck joints where possible

Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints, and report any chipped edges early.

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

Will you travel to Cross on the island?

Yes, Cross is within the area we cover. Every Scottish council area is within our area. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

Does a site in Cross have to shut while its joints are sealed?

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.

Can you work on car park ramps and decks?

Yes. Tell us how the car park is used and which areas must stay open.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
