About our floor joint sealing in Kemsing

Concrete floors in warehouses and factories are cut into bays with saw cuts and day joints, and every one of those joints is an exposed edge under hard wheels. We fill or seal them with a product matched to the traffic and the movement, so the arrises are supported and grit stays out. If you have dock area joints that have failed first and cracked and crumbling joint fill, we can put it right. A single leaking joint is often how a building in Kemsing first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In a smaller place such as Kemsing, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Concrete floors and yards in these buildings move and crack like any others.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Do you need floor joint sealing in Kemsing?

Unfilled joints soon pack with grit, shrink-wrap scraps and pallet splinters. Packed debris acts like a wedge every time a wheel crosses so the arrises break sooner.

Site and facilities staff are often the first to spot these:

  • Joint edges breaking up under truck wheels
  • Loading bay joints breaking down
  • Soft sealant dragged out of trafficked joints
  • Saw-cut joints left open and packed with grit

A healthcare site such as Sevenoaks Hospital (1.6 miles south-west of Kemsing) depends on car parks, ramps and service yards whose joints take traffic all day.

Choosing a commercial sealant contractor

Your questions answered

Can you work on a hospital site such as Sevenoaks Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Is Goya Business Park Sevenoaks, near Kemsing, within your area?

Yes. Our area takes in Kemsing and its surroundings, with estates and business parks such as Goya Business Park Sevenoaks included. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Can the sealant be colour-matched?

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

What do you need from us to quote?

Approximate metres of joint, photos of typical and worst areas, and a floor plan let us give a quick quote. We can visit where that helps, and you can ring 01277 525 020 or email a schedule or drawings to arrange it.

Will we need to close the floor?

The work is phased. Areas are taken out of use a section at a time around the site hours and access windows you give us.

Do you repair broken joint edges?

A filler needs sound edges to grip. If the arrises have spalled, we’ll say they need repair before filling, so you can decide how to proceed.

How long does a typical visit take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

From enquiry to sign-off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. Work in places the size of Kemsing is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. A floor survey records every joint, its edges and what crosses it.
  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.

Preparing the site

  • Point out any areas we must not close
  • Tell us what induction or permit system the site runs
  • For older buildings, check the asbestos register before work

Advice

Keeping the joints sound

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

  • Mention any aggressive cleaning regime at quote stage
  • Allow for topping up joints as a new slab settles
  • Ask drivers not to drag forks or pallets
  • Keep photos of joints that look like they’re failing

Keep traffic off fresh joints until the time we give you and it pays to stick to it. In a busy building, barriers keep early traffic away.

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.

How the job changes by surface

Isolation joints at walls and columns

Where racking or plant sits near column joints, access is agreed before we start so nothing has to move unexpectedly.

Flexible floor sealants

A flexible sealant suits perimeter and movement joints away from the heaviest traffic. Backing rod limits how deep the bead goes and keeps it off the joint bottom.

When to bring in a specialist

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Floors, slabs and movement joints in Kemsing

The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints. At least three named trading, business or retail sites lie within about 3 miles of Kemsing. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

In a school such as Kemsing Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. For buildings at a park such as Goya Business Park Sevenoaks, 1.3 miles south-west of Kemsing, brick and panel movement joints are easy to forget until one leaks.
