Questions we are asked in Swanwick

Does your area include sites such as Park Gate Business Centre, near Swanwick?

Yes. Our area takes in Swanwick and its surroundings, with estates and business parks such as Park Gate Business Centre included. Send details of the unit and the work through our quote form for a quick quote.

Is hospital work, at somewhere like Fareham Community Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you work in Swanwick?

Yes. Sites across Swanwick are covered, and the same phone number covers every area.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

What guarantee do you give on joint filling?

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

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Floor joint sealing for commercial buildings in Swanwick

Forklifts and pallet trucks are hard on open joints. Each crossing knocks the unsupported edge until a crisp saw cut becomes a wide, broken groove. Filling the joint properly gives the edges back their support. It also smooths the route for drivers and stock. Site teams most often ask us about untidy open joints in a retail unit and saw-cut joints left open and packed with grit, on joints along racking aisles, construction joints and saw-cut induced joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Swanwick, that means joint design, primers and backing rod as standard.

Around smaller places such as Swanwick, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area.

  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.

Advice

Different surfaces, different methods

Retail and showroom floors

Polished and coated concrete floors in shops and showrooms show every joint. A flush, neat fill in a suitable colour keeps the floor looking right and confirm which colours the product comes in.

Forklift and pallet-truck routes

Joints on busy routes need a fill that sits flush and resists impact. We match the product to the wheel types and the traffic.

Signs you need floor joint sealing in Swanwick

Soft sealant in a heavily trafficked joint gives the edges little support, so the concrete still breaks beside it. It can go the other way too: a rigid fill in a joint that is still opening cracks or debonds.

Things that typically lead to an enquiry:

  • Failing joints at loading bays and dock doors
  • Sealant pulled out along a truck route
  • Cracked and crumbling joint fill
  • Saw-cut joints left open and packed with grit

At places like Solent Business Park (1.9 miles east of Swanwick), joints are sealed a section at a time so operations carry on.

What your quote should include

  • How joint depth will be controlled
  • Will failed sealant be removed rather than covered?
  • The named product and why it was chosen
  • What site paperwork they can supply

How to choose a sealant contractor

Leave it or put it right?

Not every joint needs stripping out completely. If old material is sound on one face and only a fine gap has opened, it may not all have to come out and the quote shows which approach suits each run. Older rural buildings around Swanwick move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why us?

  • Old sealant cut out, never sealed over
  • Commercial sealant work since 2005
  • One number for every site we cover
  • Public liability insurance in place

Floor joint sealing in Swanwick: the local picture

Swanwick sits close to the coast, within about 3 miles. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, which is why split joints are worth sealing before the edges deteriorate. Rainfall across the South East, Swanwick included, is lower than in many parts of the UK. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints.

Hospitals like Fareham Community Hospital (1 mile south-east of Swanwick) have multi-storey or surface car parks whose joints carry vehicles round the clock. Office parks like Park Gate Business Centre (1 mile south-east of Swanwick) have decks, ramps and clad elevations whose joints take movement every day.

Swanwick is about 2 miles south of Hedge End, in Hampshire. We cover commercial sites throughout Swanwick, for single jobs and planned programmes alike. Swanwick is one of 723 places we cover in Hampshire for floor joints.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Remind operators to lift rather than drag
  • Hold traffic back until the product has cured
  • Treat loading bay joints first if they’re failing
  • Plan for a top-up on newer floors

We’ll 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.

Joints are easiest to look after when someone checks them regularly. We can quote a programme that starts with the busiest areas and keeps on top of the rest.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Unstable slabs moving under traffic
  • Damaged or worn floor coatings and screeds
  • Spalled arrises, which need an edge repair first

Not sure which it is? You can give us a call on 01277 525 020 or email us and we will tell you honestly before you book.
