Floor joint sealing across Stonehill Green

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Floor joint sealing in Stonehill Green

Sometimes the concrete either side of a joint has already spalled. A filler laid against broken edges has nothing sound to grip, so we will tell you if the joint edges need repairing first and explain how it affects the programme. We work on forklift and pallet-truck routes, retail and showroom floors and loading bays, and the failures we’re asked to look at most are joint edges breaking up under truck wheels and grimy joint lines spoiling a showroom floor. Facilities teams, main contractors and managing agents in Stonehill Green tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Smaller community and commercial buildings around Stonehill Green have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Slab panels that rock or move under load
  • Joint edges that have already broken away, which need repairing before filling (we will tell you if so)
  • Cracks across panels caused by settlement or overload

If in doubt, ring 01277 525 020 or use the quote form and we will say what we think before you book.

Joints and surfaces we work on

  • Loading bays
  • Saw-cut induced joints
  • Construction joints
  • Forklift and pallet-truck routes
  • Joints along racking aisles
  • Retail and showroom floors

Cost factors for floor joints

These are the things that shape the price:

  • Distance, for remote addresses
  • Whether the work must be split into stages
  • Site requirements such as inductions and permits
  • Access and working height

Pricing floor joints depends on quantities, condition and access. Call for a quote.

Before you send an enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • Clear photographs of the problem areas
  • The postcode of the building
  • The asbestos register, for older buildings
  • Specification clauses that apply

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Why deal with it now?

Open joints are where dirt collects where scrubber-driers can’t get it out. In shops, showrooms and clean production areas that matters for hygiene and appearance. Flush, filled joints leave nothing for cleaners to dig out. Converted and older buildings near places like Stonehill Green tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

From enquiry to sign-off

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work typically takes between a day and a number of days, set by the joint lengths, the edge condition and the phasing you need. For a building around Stonehill Green, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
  2. You get a fixed quote with the product and the phasing set out.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. We vacuum each run and prime it if the chosen product requires a primer.
  5. The chosen product is placed to its specified depth and trimmed level with the floor.
  6. The area is handed back once it has cured enough to take traffic.

Getting the site ready

  • Warn occupants and staff about the work
  • Agree which areas must stay open
  • Send asbestos survey details if the building is pre-2000

Get a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

After the work

Cleaning and maintenance staff play a part too. Share these points with them:

  • Expect fillers on young slabs to need a top-up
  • Respect the cure time before traffic returns
  • Make joint checks part of your floor inspections
  • Remind operators to lift rather than drag

Walk the main truck routes every few months and look along the joint lines. Look for separation down one side, new chips in the arris and debris gathering and keep photographs so changes are easy to compare.

Every day an open joint stays full of grit, the edges take more punishment. Getting it filled stops the damage while it is still a straightforward job.

Do you need floor joint sealing in Stonehill Green?

A soft, flexible sealant on a forklift route can’t hold the arrises up and the edges fail regardless. The opposite mistake happens as well: a stiff filler in a joint that keeps moving splits or comes away from the sides.

Most enquiries start with something like this:

  • Dock area joints that have failed first
  • Scruffy, dirty joint lines on a shop or showroom floor
  • A gap opening alongside old joint filler
  • Saw-cut joints left open and packed with grit

At a retail site such as Dartford Heath Retail Park, 2.4 miles north-east of Stonehill Green, trolleys, cages and cars run over floor and slab joints all day.

Before you book anyone

  • How long is the guarantee, and what does it include?
  • Will failed sealant be removed rather than covered?
  • How joint depth will be controlled
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

Stonehill Green: questions and answers

Is a hospital such as Queen Mary's Hospital somewhere you can work?

Do you repair broken joint edges?

Filling against broken edges doesn’t last. We will tell you if the joint edges need repairing first, so you can decide how to proceed.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

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

There isn’t one answer for a whole floor. Where hard wheels cross, a semi-rigid filler is normally right and perimeter or movement joints need flexibility. The quote sets out what goes where.

Why is there a gap next to the joint filler?

On newer slabs, the concrete keeps shrinking after the joints are filled and a stiff filler can separate down one side. A top-up normally puts it right.
