Questions about Dunnet

Can being near the sea in Dunnet affect the sealant we need?

It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

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

Rarely. Work is phased around your operations. The phasing plan comes with the quote.

What about RAMS and site documents?

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

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

What happens if the joint edges are damaged?

We check the edges as part of the survey. Where they have broken away, we’ll tell you before quoting the filling so the filling isn’t wasted.

Are you CHAS accredited?

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

How do we get a quote for floor joints?

A rough joint length, a few photographs and a site plan are usually enough for a quick quote. We can visit where that helps so ring 01277 525 020 or use the quote form to set one up.

When to call us in Dunnet

Concrete slabs shrink as they dry out, and the saw cuts are there so it cracks in straight, controlled lines. As the panels contract, the joints widen, and a filler placed early can part company with one face.

Clients normally get in touch after noticing one or more of the following:

  • Saw-cut joints left open and packed with grit
  • Broken arrises where pallet trucks cross
  • A rough ride across broken joints
  • A gap opening alongside old joint filler

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

Questions to ask before you book

  • How they handle RAMS and site documents
  • The terms of the workmanship guarantee
  • Will failed sealant be removed rather than covered?
  • How the joint faces will be prepared and primed

Our contractor checklist

After the work

For the best life from the joints:

  • Make joint checks part of your floor inspections
  • Remind operators to lift rather than drag
  • Put loading bays at the top of the list
  • Plan for a top-up on newer floors

We will give you a time before trucks can run over the new joints, and it’s worth enforcing. Cones or barriers stop the first driver cutting the corner.

Joint damage starts slowly and then speeds up. Each chip makes the drop deeper and the next impact harder so early treatment saves a lot of trouble.

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes a day or more, depending on the metres of joint and how many zones the floor is split into, and our waste is bagged and taken away as we go. Travel to smaller Scottish places like Dunnet is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  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. Filler or sealant is placed to depth and finished flush.
  6. Zones reopen once cured and the work moves on.

Before we start on site

  • Move anything stored against the joints
  • Tell us what induction or permit system the site runs
  • Tell us your opening times and when work is allowed

Why act early in Dunnet

Duct tape or a general builders’ sealant can seem to buy some time. Neither is made to carry wheels and traffic soon pulls it out. The right filler or sealant saves doing it twice. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Dunnet, a repair visit takes planning, so it’s better to act early.

Pricing floor joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Floor joint sealing in Dunnet: the local picture

Dunnet lies within about 1 mile of the sea. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner. Dunnet is on Scotland’s drier eastern side. Freezing weather and salt still attack open external joints. Sealing them in drier months limits winter damage.

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