Expansion joint sealing for Bonaly sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Expansion joint sealing in Bonaly, done properly

Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic, and we will confirm the choice in the quote. If you have movement joints with split or torn sealant and sealant peeling off one face of the joint, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Bonaly, that means joint design, primers and backing rod as standard.

For outside joints near Bonaly, the Scottish weather sets the timetable: dry faces and the right temperature are essential, so dates have some give. Inside slabs aren’t affected and can be scheduled around the occupier.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Keep stones and debris out of open joint lines
  • Keep traffic off new joints until the cure time is up
  • Treat a small split as a warning, not a cosmetic issue
  • Brief car park operatives to protect joint lines during winter clearance

Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in. If anything looks wrong, call 01277 525 020 or email drawings and photos with photographs.

Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load, turning a sealant job into a repair job. Keeping the seal sound avoids all of that.

Why deal with it now?

Resealing is typically the answer, not replacing the element. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we’ll tell you they need repairing first. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Bonaly, a repair visit takes planning, so it’s better to act early.

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why appoint us

  • Joints cleaned back to sound surfaces
  • One phone line for London, the South East and Scotland
  • Public liability insurance in place
  • A fixed quote before work starts

Signs you need expansion joint sealing in Bonaly

When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again.

Things that typically lead to an enquiry:

  • Hardened, cracked sealant on exposed facades
  • Expansion joints split through the centre of the bead
  • Joints packed with grit and debris
  • Damp inside where a wall movement joint has failed

For estates staff at a university like Edinburgh Napier University, 2 miles north of Bonaly, building and paving joints are part of the planned maintenance list.

What your quote should include

  • How the existing material will be dealt with
  • How long is the guarantee, and what does it include?
  • Whether their applicators hold CSCS cards
  • What level of public liability insurance do they hold?

Choosing a commercial sealant contractor

Warehouse floors and decks around Bonaly

The 3 miles around Bonaly take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. The east of Scotland, where Bonaly is, gets less rain than the west. Freezing weather and salt still attack open external joints. Sealing them before winter limits the damage.

Schools such as Army School of Bagpipe Music and Highland Drumming have movement joints in their walls and floors that are easy to overlook. Large sites such as Royal Edinburgh Hospital, 2.7 miles north-east of Bonaly, have car parks, service roads and long elevations with movement joints in brick and panels.

FAQs: Bonaly

Can you work on a hospital site such as Royal Edinburgh Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Will you take on work at estates like Dumbryden Industrial Estate, close to Bonaly?

Yes. Estates, retail parks and business parks around Bonaly, Dumbryden Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

How long will the joint resealing take?

Allow a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. We confirm the timescale with the quote.

What will the job cost?

Each job is quoted on its own details. To get one, call 01277 525 020 or use the quote form.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Can you seal joints in cold or wet weather?

Weather matters for any external joint. Internal floor joints are far less affected.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Movement on a scale no sealant is meant to absorb
  • Broken or spalled joint edges, which need repairing before any sealant goes in

If you are not sure, just ring 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

What we seal

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

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Bonaly, we aim for one trip, so photos, sizes and a full list matter. External joints need a dry spell as well.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  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.

Before we start on site

  • Move anything stored against the joints
  • Warn occupants and staff about the work
  • Point out parking and an unloading spot

Site staff or a sealant specialist?

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

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
