Floor joint sealing in Boxgrove

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

Floor joint sealing in Boxgrove

It isn’t only heavy industry. Retail units, showrooms and trade counters have slab joints crossed by trolleys, footfall and cleaning machines, and an open, grimy joint line looks poor as well as catching wheels. A neat, flush fill makes the floor easier to clean and look after. We work on forklift and pallet-truck routes, loading bays and construction joints, and the failures we’re asked to look at most are old filler gone hard, cracked or loose and sealant pulled out along a truck route. One point of contact handles commercial sealant work in Boxgrove from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Around smaller places such as Boxgrove, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

How a job runs

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For work around Boxgrove, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  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. We hand each phase back when it can take traffic.

What we need from you

  • Point out parking and an unloading spot
  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work

Owners, agents and contractors

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

Why deal with it now?

Dirt and spillage gather in open joints where scrubber-driers can’t get it out. In shops, showrooms and clean production areas that matters for hygiene and appearance. Filled joints are far simpler to keep clean. Older rural buildings around Boxgrove move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

After the work

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Make joint checks part of your floor inspections
  • Keep photos of joints that look like they’re failing
  • Expect fillers on young slabs to need a top-up
  • Ask drivers not to drag forks or pallets

We will give you a time before trucks can run over the new joints and it pays to stick to it. In a busy building, barriers keep early traffic away.

While the concrete edges are intact, it’s a filling job. Once they have broken away, edge repair comes first, with more downtime and more disruption.

Joints that move: notes for Boxgrove

Rainfall across the South East, Boxgrove included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in. The 3 miles around Boxgrove take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.

Parks like Chichester Business Park., 0.5 miles to the south of Boxgrove, combine paved areas, car parks and building elevations, each with joints that move. Hospitals like St Richard's Hospital (to the west of Boxgrove) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Boxgrove is about 3 miles north-east of Chichester, in West Sussex. We cover Boxgrove and the rest of West Sussex, with the same fixed quotes and 12-month guarantee as everywhere else. Across West Sussex, 373 places are covered, Boxgrove among them. Portsmouth is covered too, around 16 miles from Boxgrove.

Commercial sites across PO18 are covered. Buildings on The Street, Priory Close and Kirkby Close are within our area for floor joints. If your building is just outside Boxgrove, we cover Halnaker (1 mile north), Tangmere (1 mile south), Strettington (1 mile west), Waterbeach (1 mile north-west) and Westerton (1 mile west). Bigger towns within reach include Worthing (14 miles east), Bognor Regis (5 miles south), Chichester (3 miles south-west), Selsey (9 miles south), Littlehampton (9 miles east) and Rustington (9 miles east).

When to call us in Boxgrove

Loading bay joints are exposed to wind, wet tyres and bigger temperature swings on top of the heaviest turning movements. They are often the first on a site to break down.

Clients usually get in touch after noticing something like this:

  • Loading bay joints breaking down
  • A rough ride across broken joints
  • Flexible sealant torn out by wheels
  • Unfilled floor joints collecting dirt and grit

Schools like Boxgrove CofE Primary School often have long brick elevations with movement joints that age quietly.

Before you book anyone

  • How the joint faces will be prepared and primed
  • Whether their applicators hold CSCS cards
  • How they handle RAMS and site documents
  • Will failed sealant be removed rather than covered?

Questions we are asked in Boxgrove

Is Boxgrove too small for you to travel to?

Not at all. Boxgrove is within our area. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Does your area include sites such as Chichester Business Park., near Boxgrove?

Yes, sites like Chichester Business Park. Are within our area, along with the rest of Boxgrove. To start, just speak to us on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

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.

What do you need from us to quote?

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.

Will we need to close the floor?

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

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
