Floors, slabs and movement joints in Selborne

At least three named trading, business or retail sites lie within about 3 miles of Selborne. Their warehouses, yards and car parks are exactly where joints take the most punishment. Selborne is about 46 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

Phasing is what makes joint work possible on busy sites such as Farringdon Industrial Centre (2.4 miles west of Selborne): one bay, aisle or car park row at a time. For a school such as Selborne Church of England Primary School, playground and building joints can be done in the holidays.

Selborne is about 4 miles south of Alton, in Hampshire. Our applicators travel to Selborne for work on floor joints. We work across 723 places in Hampshire, from busy centres to rural villages. For work in that direction, see our Portsmouth page.

We cover the GU34 postcode districts. For a building on Huckers Lane, Ganders Close and Selborne Road or nearby, send details and we’ll quote for floor joints. Just outside Selborne, we also work in Newton Valence (1 mile west), Empshott (2 miles south-east), Lower Green (3 miles south), Hawkley (3 miles south) and Oakshott (4 miles south).

Floor joint sealing in Selborne

For sites in Selborne and across Hampshire, the process is short: send details, get a fixed quote, we seal, and the work is guaranteed. Approximate joint lengths, a few photographs and a floor plan are enough for a quick quote and a visit can be arranged where that is easier. We work on forklift and pallet-truck routes, joints along racking aisles and retail and showroom floors, and the failures we’re asked to look at most are joint fill separating from the concrete and scruffy, dirty joint lines on a shop or showroom floor. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Selborne, that means joint design, primers and backing rod as standard.

For a site near Selborne, measurements and photographs up front mean one trip where possible, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

Looking after the joints

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

  • Respect the cure time before traffic returns
  • Mention any aggressive cleaning regime at quote stage
  • Keep grit out of unfilled joints in the meantime
  • Plan for a top-up on newer floors

Once cured, the joints get cleaned along with the slab. Tell us about aggressive cleaning products or hot washing at quote stage so the product suits them.

A broken joint on a main route is crossed by every truck on that route. Early treatment protects wheels, loads and drivers as much as the floor.

What happens if it’s left?

Open joints are where dirt collects, out of reach of the floor cleaner. Where the floor is on show or needs to be kept clean, that is a problem. Flush, filled joints leave nothing for cleaners to dig out. Older rural buildings around Selborne move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Commercial clients in Selborne

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Selborne can form part of a wider programme.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Selborne need work, visits can be combined. A fixed quote is given before anything starts.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. A fixed quote follows, listing the treatment for each area and the order of work.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
  5. The chosen product is placed to its specified depth and trimmed level with the floor.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

What we need from you

  • Point out any areas we must not close
  • Let building users know which areas are affected
  • Send any specification or drawings in advance

How the job changes by surface

Flexible floor sealants

Movement joints, joints at walls and joints in lightly trafficked areas often take a flexible sealant. Backing rod limits how deep the bead goes and keeps it off the joint bottom.

Construction joints

Construction joints, sometimes called day joints, mark where one pour ended and the next began. They can move more than saw cuts and that shapes the choice of filler or sealant.

When to call us in Selborne

Joints near dock doors see colder air, rain blown in and water off vehicles on top of the heaviest turning movements. That is typically where joint failure starts.

Most enquiries start with one or more of the following:

  • Trucks and loads jolting over damaged joints
  • Untidy open joints in a retail unit
  • Broken arrises where pallet trucks cross
  • Loading bay joints breaking down

Large sites such as Alton Community Hospital, 3.5 miles to the north-west of Selborne, have car parks, service roads and long elevations with movement joints in brick and panels.

Questions to ask before you book

  • How the existing material will be dealt with
  • Their public liability cover
  • The named product and why it was chosen
  • Their pre-qualification and accreditations

How to choose a sealant contractor

Your questions answered

Would you work within a site like Alton Community Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you cover business parks and estates near Selborne, such as Southlands Industrial Park?

Yes, sites like Southlands Industrial Park are within our area, along with the rest of Selborne. 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.

Why has the filler pulled away from one side?

It can be shrinkage, contamination on the joint faces or a product unsuited to the movement. We look at which it is before recommending anything.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

How soon can traffic go back on the floor?

Each product has its own cure time, and cold floors slow it down. Phasing is planned with that in mind.

Can you fill joints where the arrises have spalled?

Edge condition is recorded when we look at the floor. Damaged edges are flagged up front so the filling isn’t wasted.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
