Expansion joint sealing across Rattar

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

Diagnose, treat, sign off

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Jobs near Rattar are often grouped with others in the same area. Let us know if your dates have any give.

  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. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Getting the site ready

  • Agree which areas must stay open
  • Make sure the joints can be reached
  • Share your working hours and any access restrictions

Expansion joint sealing in Rattar, done properly

Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. We work on car park decks and ramps, blockwork control joints and cladding panel joints, and the usual reasons a site gets in touch are damp inside where a wall movement joint has failed and water dripping through deck or ramp joints. Looking for mastic applicators who cover Rattar? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

For floor or movement joints around smaller places like Rattar, we plan to finish in one visit where we can. Photos, approximate widths and what uses the floor help us bring the right materials.

Common problems we fix in Rattar

Car park decks and floors face loads that walls never see. Wheel loads stress the sealant and the arrises, while de-icing salts and grit attack the seal. The product has to be suited to the traffic.

Typical triggers for a call:

  • Leaks through car park deck joints onto the level below
  • Brittle, chalky sealant on external joints
  • Chipped joint edges on forklift routes
  • Damp inside where a wall movement joint has failed

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

What your quote should include

  • Whether their applicators hold CSCS cards
  • Is the sealant right for the movement and the substrate?
  • Their approach to joint depth and backing
  • Health and safety accreditation such as CHAS

Questions to ask before you appoint anyone

Commercial clients in Rattar

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

What the job involves on each surface

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen, and we’ll confirm the colours available for the specified product.

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. We use a sealant classed for the movement, laid over backing to depth.

Slabs, ramps and loading bays in Rattar

Rattar lies within about 1 mile of the sea. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, and edges left open tend to break up faster. Rattar is in the east of Scotland, which is drier than the west. Frost and de-icing salt still find their way into open external joints. Autumn is a sensible time to seal them.

Once a joint near Rattar opens up, grit and water get in and the edges start to break.

Rattar is about 10 miles east of Thurso, in Highland. We send applicators to Rattar for movement joints. We work across 256 places in Highland, large and small.

Why act early in Rattar

Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall. Resealing early keeps the work to sealant. For buildings near Rattar, dealing with all the failing joints at once saves return trips. Send photographs and we will quote for everything together.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Questions we’re asked in Rattar

Do we have to stop operations in Rattar while the joints are sealed?

Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we will plan from there.

Is Rattar too small for you to travel to?

Not at all. Rattar is within our area. Our area covers all of Scotland, cities, towns and islands alike. Where we can, we group nearby jobs to make the most of each trip.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

What causes movement joint sealant to fail?

The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. We diagnose which one it is before resealing since each needs a different fix.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Can you work while the building is occupied?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Can you send site paperwork?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Maintenance after handover

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Check joints after long freezing spells
  • Reopen bays and walkways only after the stated cure time
  • Include every elevation and deck joint in periodic inspections
  • Keep stones and debris out of open joint lines

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check. If anything looks wrong, call the office on 01277 525 020 or send photos by email with photographs.

Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one so you can prioritise and budget. We will tell you which movement joints need doing now and which can wait.
