Floor joint sealing for Enfield Wash sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Unstable slabs moving under traffic
  • Level or flatness problems across the floor
  • A failing floor coating, which is a flooring contractor’s job

If you are not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Where we work in Enfield Wash

  • Forklift and pallet-truck routes
  • Saw-cut induced joints

About our floor joint sealing in Enfield Wash

Few warehouses can shut a whole floor while joints are done, so the work is split into zones and treated one area at a time. Tell us your site hours and access windows and we will plan around them so the rest of the operation keeps going. We work on construction joints, retail and showroom floors and saw-cut induced joints, and the failures we’re asked to look at most are broken arrises where pallet trucks cross 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 Enfield Wash, that means joint design, primers and backing rod as standard.

London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. Planning a job in Enfield Wash means thinking about access, loading times and the ULEZ as well as the joints.

Our workmanship is guaranteed for 12 months, in Enfield Wash as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

For managing agents and facilities managers

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Signs you need floor joint sealing in Enfield Wash

Concrete slabs shrink as they dry out, and saw-cut joints give that shrinkage a planned place to crack. As the panels contract, the joints widen, and a filler placed early can part company with one face.

Any of the following is a good reason to get the joints checked over:

  • Scruffy, dirty joint lines on a shop or showroom floor
  • Dock area joints that have failed first
  • Cracked and crumbling joint fill
  • Drivers complaining about joints on a route

Retail parks like Enfield Highway Shopping Centre (to the south-west of Enfield Wash) have long runs of car park and yard joints taking daily traffic.

Questions to ask before you book

  • Can the work be phased to keep areas open?
  • Who will actually carry out the work
  • Is the sealant right for the movement and the substrate?
  • Their public liability cover

Our contractor checklist

Different surfaces, different methods

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.

Isolation joints at walls and columns

Joints at walls and columns are often missed when floors are sealed and fill up with dirt. We include them in the survey.

Looking after the joints

After handover, a little attention goes a long way:

  • Sweep debris out of open joints until they can be filled
  • Ask drivers not to drag forks or pallets
  • Let us know what the floor is cleaned with
  • Hold traffic back until the product has cured

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.

Treating joints while the arrises are sound keeps the work simple. Once they have broken away, edge repair comes first and that takes longer and closes areas for longer.

Enfield Wash: questions and answers

Can you work in a London building with booked loading and goods-lift slots?

Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

Can you work on a hospital site such as St Michael's Community Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

What information helps you price floor joint sealing?

Approximate metres of joint, photographs of typical and worst areas, and a floor plan let us give a quick quote. We can visit where that helps, and you can call the office on 01277 525 020 or email drawings and photos to arrange it.

Are you fully insured?

Yes. We are fully insured, and the certificate can go with your quote.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Do you offer coloured sealant?

It depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

When can forklifts run over new joint filler?

Each product has its own cure time and cooler floors take longer. We plan the phasing so that waiting time fits your operation.

On site: what to expect

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  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.

What we need from you

  • Tell staff and tenants when we will be in
  • Share your working hours and any access restrictions
  • Agree which areas must stay open

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Traffic, movement and joints around Enfield Wash

Sites like St Michael's Community Hospital (2 miles west of Enfield Wash) carry ambulances, deliveries and visitors’ cars over their road and deck joints. In a school such as Eastfield Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
