Floor joint sealing for commercial buildings in Atherington

Open joints take a beating from forklift and pallet-truck wheels. Each crossing knocks the unsupported edge until a crisp saw cut becomes a wide, broken groove. A properly filled joint carries the wheel over and protects both arrises, which is kinder to trucks, loads and operators. We work on forklift and pallet-truck routes, loading bays and construction joints, and the failures we are asked to look at most are joint fill separating from the concrete and flexible sealant torn out by wheels. Whether you call it commercial sealant work, mastic application or joint sealing, in Atherington it comes down to the same thing: the right product in a properly prepared joint.

Jobs around smaller places like Atherington are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building around Atherington, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  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. Each joint is cut or routed back to clean, sound concrete.
  4. Dust is vacuumed out and primer applied where specified.
  5. The joint is filled to its specified depth and trimmed level.
  6. Zones reopen once cured and the work moves on.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Move anything stored against the joints
  • Explain the parking and delivery arrangements

Atherington: questions and answers

Is a smaller place like Atherington outside your area?

Not at all. Atherington is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Can you take on a job at a hospital such as Zachary Merton Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

What happens if old sealant might contain asbestos?

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

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

What information helps you price floor joint sealing?

Send details through our quote form or by email and tell us what runs on the floor. We then send a fixed quote that shows the products and zones.

Owners, agents and contractors

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Floor joint sealing in Atherington: the local picture

Atherington is within about 1 mile of the coast. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, and edges left open tend to break up faster. Atherington is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.

Campuses like University of Chichester (Bognor Campus) (3.8 miles west of Atherington) mix old and new buildings, with movement joints wherever they meet. Estates like Rudford Industrial Estate, 0.8 miles north of Atherington, combine warehouse slabs, yards and loading bays, all with joints under wheels.

Common problems we fix in Atherington

Unfilled joints soon pack with grit, shrink-wrap scraps and pallet splinters. That debris is hard and levers at the edges as wheels pass so the arrises break sooner.

Most enquiries start with one or more of the following:

  • Joint fill separating from the concrete
  • Flexible sealant torn out by wheels
  • Drivers complaining about joints on a route
  • Dock area joints that have failed first

In a school such as St Mary's CofE Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Before you book anyone

  • What level of public liability insurance do they hold?
  • Will failed sealant be removed rather than covered?
  • Their plan for phasing and protecting the area
  • Health and safety accreditation such as CHAS

Questions to ask before you appoint anyone

Keeping the joints sound

After handover, a little attention goes a long way:

  • Walk the main routes and inspect joint lines on a regular cycle
  • Keep photos of joints that look like they’re failing
  • Allow for topping up joints as a new slab settles
  • Mention any aggressive cleaning regime at quote stage

If a joint we filled starts to break up within 12 months, tell us and we will arrange a look. Beyond that, an inspection once or twice a year catches failing joints early.

Every day an open joint stays full of grit, the edges take more punishment. Getting it filled stops the damage before it becomes a repair.

Doing it in-house

Site maintenance staff can often handle a short internal joint. 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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

How the job changes by surface

Saw-cut induced joints

Most of the joints in a warehouse floor are saw cuts. Each one is cleaned out and filled to the specified depth, finishing flush with the slab.

Semi-rigid joint fillers

A semi-rigid filler is stiff enough to hold the arrises up when wheels cross. They allow only small movement so timing matters on newer slabs.
