Floor joint sealing in Unthank

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

Doing it in-house

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

About our floor joint sealing in Unthank

For sites in Unthank and across Angus, the process is short: send details, get a fixed quote, we seal, and the work is guaranteed. Approximate joint lengths, a few photographs and a floor plan are enough for a quick quote and a visit can be arranged where that is easier. We work on construction joints, forklift and pallet-truck routes and loading bays, and the usual reasons a site gets in touch are saw-cut joints left open and packed with grit and grimy joint lines spoiling a showroom floor. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Unthank it comes down to the same thing: the right product in a properly prepared joint.

In smaller places such as Unthank, the joints we are asked about sit in workshops, farm sheds, schools and halls. Concrete slabs and yards there take vehicles and weather.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

What we’re called out for in Unthank

Concrete slabs shrink as they dry out, and saw-cut joints give that shrinkage a planned place to crack. As the panels contract, the joints widen so a filler put in early may separate along one side.

If one of these sounds familiar, it’s time for a closer look:

  • Trucks and loads jolting over damaged joints
  • Dock area joints that have failed first
  • Soft sealant dragged out of trafficked joints
  • Filler that has parted from one face

For buildings at a park such as Brechin Business Park, 1.2 miles south-west of Unthank, brick and panel movement joints are easy to forget until one leaks.

What to look for in a quote

  • What level of public liability insurance do they hold?
  • Do they follow the manufacturer’s priming guidance?
  • Will RAMS and insurance details be available?

How to choose a sealant contractor

Diagnose, treat, sign off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. For work around Unthank, we aim for one trip, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. The treatment and the zones are set out in a fixed quote.
  3. Old fill and packed debris come out until both faces are sound.
  4. Dust is vacuumed out and primer applied where specified.
  5. The joint is filled to its specified depth and trimmed level.
  6. We hand each phase back when it can take traffic.

What we need from you

  • Point out parking and an unloading spot
  • Tell us what induction or permit system the site runs
  • Agree which areas must stay open

Honest limits

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

  • A floor that rocks at the joints, which needs a structural fix
  • Level or flatness problems across the floor
  • Joint edges that have already broken away, which need repairing before filling (we’ll tell you if so)

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

What we seal

  • Loading bays
  • Construction joints
  • Saw-cut induced joints
  • Forklift and pallet-truck routes
  • Joints along racking aisles
  • Retail and showroom floors

Why act early in Unthank

Some runs only need partial renewal or topping up. If old material is sound on one face and only a fine gap has opened, it may not all have to come out and the quote shows which approach suits each run. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Unthank, a repair visit takes planning, so it’s better to act early.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Why appoint us

  • Constructionline member for supplier checks
  • One contact handling all your sites
  • Commercial sealant work since 2005
  • Products installed to the manufacturer’s instructions

Keeping the joints sound

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Ask drivers not to drag forks or pallets
  • Allow for topping up joints as a new slab settles
  • Keep trucks off new joints until we say they’re ready
  • Clear packed debris from open joints regularly

Dragged forks and pallets gouge joints and edges alike. Steel tines will mark a good joint over time.

A broken joint on a main route is crossed by every truck on that route. Sorting it early looks after your equipment as well as the slab.

Floors, slabs and movement joints in Unthank

Unthank is on Scotland’s drier eastern side. Cold winters and gritting are hard on any yard or deck joint left open. Sealing them before winter limits the damage.

A healthcare site such as Stracathro Hospital, 2.8 miles north-east of Unthank, depends on car parks, ramps and service yards whose joints take traffic all day. For a school such as Brechin High School, playground and building joints can be done in the holidays.

Unthank is about 7 miles west of Montrose, in Angus. Unthank sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Unthank is one of 65 places in Angus on our list for floor joints. Dundee is covered too, around 22 miles from Unthank.

Work on floor joints is covered throughout DD9, whatever the building. Buildings on Trinity Road, Eddie Avenue and Cookston Road are within our area for floor joints. We also cover Brechin (1 mile south), Little Brechin (2 miles north-west), Edzell (5 miles north), Edzell Woods (5 miles north) and Craigo (6 miles east) for floor joints. Nearby towns on our patch include Arbroath (13 miles south), Forfar (11 miles south-west), Montrose (7 miles east), Kirriemuir (14 miles west), Letham (9 miles south-west) and Hillside (7 miles east).

Questions about Unthank

Do you take on work at healthcare sites like Stracathro Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Does your area include sites such as Brechin Business Park, near Unthank?

Yes, sites like Brechin Business Park are within our area, along with the rest of Unthank. A few photographs and the unit address let us price the work.

Do you repair broken joint edges?

Filling against broken edges doesn’t last. We will tell you if the joint edges need repairing first and set out how that affects the job.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

What guarantee do you give on joint filling?

Every job has our 12-month guarantee. It applies to our workmanship rather than structural movement or accidental damage.

Why is there a gap next to the joint filler?

Young concrete carries on shrinking for a long time, so a semi-rigid filler can part from one face. A top-up normally puts it right.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
