Floor joint sealing in Westcroft, done properly

We have been sealing commercial joints since 2005. Applicators carry CSCS cards and work to your site rules, and the business is CHAS accredited and a Constructionline member holding public liability insurance. Completed joints come with a 12-month guarantee on our workmanship. We work on joints along racking aisles, retail and showroom floors and saw-cut induced joints, and the usual reasons a site gets in touch are failing joints at loading bays and dock doors and unfilled floor joints collecting dirt and grit. Whoever orders the work in Westcroft, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Work in a smaller place like Westcroft is normally one building at a time, so we gather photographs and measurements first. That way the right materials come on the day and the job is done in one visit where possible.

Every job we finish is backed by a 12-month workmanship guarantee, in Westcroft as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Why it’s worth doing now in Westcroft

Holding off until the whole floor can close can take a long time. Zone by zone, the worst aisles can be dealt with now while the rest of the floor carries on. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a job in Westcroft, the main thing is a clear picture of the work. A fixed quote follows.

  1. A floor survey records every joint, its edges and what crosses it.
  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. Filler or sealant is placed to depth and finished flush.
  6. Zones reopen once cured and the work moves on.

Preparing the site

  • Move anything stored against the joints
  • Explain the parking and delivery arrangements
  • Agree which areas must stay open

Related advice

Different surfaces, different methods

Isolation joints at walls and columns

Where racking or plant sits near column joints, access is agreed before we start so nothing has to move unexpectedly.

Saw-cut induced joints

Induced joints are sawn into a new slab to control where it cracks. They start narrow and widen as the concrete dries so trafficked runs need a filler that holds the arrises.

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Keep trucks off new joints until we say they’re ready
  • Put loading bays at the top of the list
  • Allow for topping up joints as a new slab settles
  • Let us know what the floor is cleaned with

Walk the main truck routes every few months and look along the joint lines. Watch for filler pulling away from an edge, fresh chipping or grit collecting, and photograph anything that changes.

Edges tend to break slowly at first, then quickly. Each chip makes the drop deeper and the next impact harder so early treatment saves a lot of trouble.

Your questions answered

Will you take on work at estates like North Furzton Shopping Centre, close to Westcroft?

Yes, sites like North Furzton Shopping Centre are within our area, along with the rest of Westcroft. To start, just give us a call on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Is Westcroft off your patch?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

How long before trucks can use the joints?

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 offer coloured sealant?

It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators.

Joints that move: notes for Westcroft

Rainfall across the South East, Westcroft 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 winter de-icing salt on car parks and ramps works into any open joint. At about 46 miles from central London, Westcroft is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift.

Across sites such as Crownhill Business Park, 1.8 miles to the north of Westcroft, floor and movement joints can be sealed in phases so units keep working. Schools like Oxley Park Academy often have long brick elevations with movement joints that age quietly. For estates staff at a university like University of Bedfordshire Milton Keynes Campus, which lies north-east of Westcroft, building and paving joints are part of the planned maintenance list.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:

  • Cracks across panels caused by settlement or overload
  • Spalled arrises, which need an edge repair first
  • A failing floor coating, which is a flooring contractor’s job
