Joints that move: notes for Crofton

Crofton lies within about 1 mile of the sea. 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. Less than 3 miles from Crofton there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Across sites such as Collingwood Retail Park, 1.1 miles north-east of Crofton, floor and movement joints can be sealed in phases so units keep working. University campuses such as University of Portsmouth - North Zone (to the east of Crofton) have car parks, paved walkways and building elevations with movement joints. Retail parks like Speedfields Retail Park, 0.9 miles to the north-east of Crofton, have long runs of car park and yard joints taking daily traffic.

Floor joint sealing in Crofton

Open joints take a beating from forklift and pallet-truck wheels. Each crossing knocks the unsupported edge, and over time a neat cut turns into a ragged channel. Filling the joint properly gives the edges back their support. It also smooths the route for drivers and stock. We work on retail and showroom floors, loading bays and joints along racking aisles, and the usual reasons a site gets in touch are soft sealant dragged out of trafficked joints and brittle joint filler breaking up. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Crofton, that means joint design, primers and backing rod as standard.

Around smaller places such as Crofton, 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.

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

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For a building around Crofton, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. A floor survey records every joint, its edges and what crosses it.
  2. You receive a fixed quote showing products and phasing.
  3. Each joint is cut or routed back to clean, sound concrete.
  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

  • For older buildings, check the asbestos register before work
  • Let us know about inductions and permits
  • Arrange parking or a loading space

Advice

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Crofton can sit alongside others in a wider programme.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Cost factors for floor joints

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Whether old sealant has to be cut out first
  • Whether the work must be split into stages
  • Backing rod, priming and other preparation
  • Which sealant the job calls for

There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.

What we need to price the job

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • The product your specification calls for
  • Access details, including height
  • Approximate linear metres or a joint schedule
  • Your programme or deadline

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or email drawings and photos.

Common questions from Crofton clients

Is Crofton too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Is a hospital such as Gosport War Memorial Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

How soon can traffic go back on the floor?

Cure times vary with the product and how cold the slab is. We’ll give you a time for each zone when we agree the phasing.

Do you use semi-rigid filler or flexible sealant on floor joints?

We decide joint by joint. Where hard wheels cross, a semi-rigid filler is usually right, and movement joints or perimeters need something flexible. You’ll see the choice for each area in the quote.

Are you insured?

Yes. We’re fully insured, including public liability cover.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards.

After the work

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

  • Expect fillers on young slabs to need a top-up
  • Record damaged joints with a photo and a location
  • Treat loading bay joints first if they’re failing
  • Sweep debris out of open joints until they can be filled

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.

Joint damage starts slowly and then speeds up. Once the first piece is out, wheels drop further and hit harder so early treatment saves a lot of trouble.

When to bring in a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What we can’t put right

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Broken concrete either side of the joint
  • Structural cracking in the slab
  • Damaged or worn floor coatings and screeds

If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think.
