Maintenance after handover

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

  • Clear packed debris from open joints regularly
  • Respect the cure time before traffic returns
  • Allow for topping up joints as a new slab settles
  • Check joint lines on busy aisles regularly

Ask drivers not to drag forks or pallets along the floor. Steel tines will mark a good joint over time.

While the concrete edges are intact, it’s a filling job. Once they have broken away, edge repair comes first and that takes longer and closes areas for longer.

About our floor joint sealing in Direcleit

We diagnose the floor first rather than guessing at a product: joint widths, whether the joints are still opening, what runs over them and how the edges have held up. That tells us whether semi-rigid filler or flexible sealant suits each run, area by area where it needs to be. Most enquiries involve sealant pulled out along a truck route and grimy joint lines spoiling a showroom floor, across loading bays, forklift and pallet-truck routes and joints along racking aisles. One point of contact handles commercial sealant work in Direcleit from the first photographs to the final walk-round, for single jobs and planned programmes alike.

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

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Different surfaces, different methods

Construction joints

Day joints on busy routes are prone to edge damage. Movement and traffic are both checked before we decide what goes in.

Saw-cut induced joints

Open saw cuts collect grit and break at the arris. Filled in good time, they stay narrow and neat.

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Direcleit, we aim for one trip, so photographs, sizes and a full list matter. External joints need a dry spell as well.

  1. First, the zones and order of work are agreed with you.
  2. Any joints with broken edges are flagged before work starts.
  3. Failed material and debris are removed and the joint cleaned.
  4. The chosen filler or sealant goes in flush with the slab.
  5. You get a time for each zone to reopen.

Getting the site ready

  • Send your site hours and access windows
  • Confirm the product named in the specification
  • Tell us which areas need to stay in use

Joints that move: notes for Direcleit

Direcleit lies within about 1 mile of the sea. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so it pays to keep them sealed. Direcleit is on Scotland’s wetter western side. Rainwater through open yard and deck joints is a bigger issue here than in the drier east. Outside joints are sealed in dry spells, so dates have some give.

For floors and slabs around Direcleit, the product is chosen for the traffic and the movement at each joint.

Direcleit (Gaelic: Diraclett) is in Na h-Eileanan Siar. We send applicators to Direcleit for floor joints. Across Na h-Eileanan Siar, 87 places are covered, including Direcleit.

Signs you need floor joint sealing in Direcleit

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, and a filler placed early can part company with one face.

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

  • Trucks and loads jolting over damaged joints
  • Broken arrises where pallet trucks cross
  • Scruffy, dirty joint lines on a shop or showroom floor
  • Filler that has parted from one face

Around Direcleit, open joints collect water and debris, and the arrises are the next to go; we will tell you if the edges need repairing first.

Questions to ask before you book

  • Health and safety accreditation such as CHAS
  • What the guarantee covers, and for how long
  • How joint depth will be controlled
  • Whether primer will be used where the manufacturer specifies it

Our contractor checklist

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Damaged or worn floor coatings and screeds
  • Structural cracking in the slab
  • A floor that rocks at the joints, which needs a structural fix

If in doubt, give us a call on 01277 525 020 or send details through our quote form and we will say what we think before you book.

Your questions answered

Does the sea air around Direcleit change the choice of sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Does a site in Direcleit have to shut while its 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.

Do you guarantee industrial floor joints?

A 12-month guarantee covers the work we do. It covers our workmanship, not later slab movement or damage from impacts.

Do you offer coloured sealant?

It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Is it normal for joint filler to separate?

On newer slabs, the concrete keeps shrinking after the joints are filled and a stiff filler can separate down one side. It is normally dealt with by topping up.

Can the warehouse stay open while you work?

In most cases, just the area being treated is coned off. Traffic returns to each zone once it has cured, then we move to the next.
