How we handle floor joint sealing in Northington

We diagnose the floor first rather than guessing at a product: how wide the joints are, signs of ongoing movement, the wheel types crossing them and the state of the arrises. That tells us whether semi-rigid filler or flexible sealant suits each run and the answer can differ from one zone to the next. Site teams most often ask us about chipped and spalling edges along forklift routes and trucks and loads jolting over damaged joints, on loading bays, forklift and pallet-truck routes and construction joints. Most enquiries from Northington start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In and around smaller places like Northington, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Our workmanship is guaranteed for 12 months, in Northington as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Joints that move: notes for Northington

Central London is about 54 miles from Northington. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint.

Around Northington, open joints collect water and debris, and the arrises are the next to go.

Northington is about 7 miles north-east of Hyde, in Hampshire. We send applicators to Northington for floor joints. Northington is one of 723 places we cover in Hampshire. For work in that direction, see our Southampton page, about 17 miles away.

What sets the cost

Before we quote, we look at:

  • Quantities, in metres or numbers
  • Working within restricted access windows
  • Site requirements such as inductions and permits
  • Distance, for remote addresses

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • Asbestos survey details if the building is older
  • The product your specification calls for
  • Whether the building will be occupied during the work
  • Any dates the work must fit around

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or ring 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Rural sites near Northington may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  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. We extract the dust and prime the faces if the product needs it.
  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

  • Make sure the joints can be reached
  • Point out any areas we must not close
  • Send asbestos survey details if the building is pre-2000

Advice

Questions we’re asked in Northington

Does a site in Northington have to shut while its joints are sealed?

Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.

Which documents can you supply for work in Northington?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Do your applicators hold CSCS cards?

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

Why has the filler pulled away from one side?

Young concrete carries on shrinking for a long time and a stiff filler can separate down one side. It is usually dealt with by topping up.

Do you cover Northington?

Yes. Northington is in our area and the rest of Hampshire, within our coverage of Greater London, South East England and Scotland. For a quote, call 01277 525 020 or email the details over.

How long before trucks can use the joints?

Cure times vary with the product and how cold the slab is. You will get a reopening time for each area before we start.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Common problems we fix in Northington

A slab keeps shrinking for a long time after it is cast, and saw-cut joints give that shrinkage a planned place to crack. Each panel pulls back as it shrinks and the joints open up so a filler put in early may separate along one side.

Typical triggers for a call:

  • Failing joints at loading bays and dock doors
  • Saw-cut joints left open and packed with grit
  • Sealant pulled out along a truck route
  • Trucks and loads jolting over damaged joints

In and around Northington, the right filler or sealant for each joint depends on the traffic and the movement it takes.

What to look for in a quote

  • Is the sealant right for the movement and the substrate?
  • The terms of the workmanship guarantee
  • Who will actually carry out the work
  • How the existing material will be dealt with

How to choose a sealant contractor

Different surfaces, different methods

Loading bays and dock areas

Bays can be treated one or two at a time so goods in and out carry on. Tell us your site hours and access windows and we’ll plan around them.

Forklift and pallet-truck routes

Main aisles and cross routes carry the most wheel movements and the joints on them break down first. Semi-rigid fillers are widely used on these routes to hold the edges up.

Commercial clients in Northington

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Slab panels that rock or move under load
  • Joint edges that have already broken away, which need repairing before filling (we’ll tell you if so)
  • Level or flatness problems across the floor

Not sure which it is? You can speak to us on 01277 525 020 or email us and we will tell you honestly.
