Floor joint sealing across Upper Green

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

Floor joint sealing for commercial buildings in Upper Green

Before quoting, we look at what the floor is telling us: 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, area by area where it needs to be. If you are dealing with joint fill separating from the concrete and joint edges breaking up under truck wheels, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Upper Green it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a site near Upper Green, measurements and photos up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Common problems we fix in Upper Green

A soft, flexible sealant on a forklift route can’t hold the arrises up, so the concrete still breaks beside it. The opposite mistake happens as well: a rigid fill in a joint that is still opening cracks or debonds.

It’s worth sending us details if you spot any of the following:

  • Joint edges breaking up under truck wheels
  • Open saw cuts full of debris
  • Dock area joints that have failed first
  • Untidy open joints in a retail unit

For buildings at a park such as Stype Business Centre, 2.9 miles to the west of Upper Green, brick and panel movement joints are easy to forget until one leaks.

What to look for in a quote

  • How long is the guarantee, and what does it include?

How to choose a sealant contractor

Why deal with it now?

Tape, or whatever sealant is in the stores cupboard, may look like a fix for a while. None of it is designed for wheel loads, and it usually ends up dragged across the floor. A product chosen for the traffic and movement does the job once. Halls, stores and units around places like Upper Green may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Why appoint us

  • Fixed quotes based on photographs, drawings or a visit
  • Products installed to the manufacturer’s instructions
  • Commercial sealant work since 2005
  • One number for every site we cover

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Upper Green can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. We agree the traffic routes and phasing with your site team.
  2. We point out joints whose edges need repairing first.
  3. We clear each run back to clean concrete.
  4. We fill the joints with the agreed product, finished level.
  5. You get a time for each zone to reopen.

Getting the site ready

  • Let us know about inductions and permits
  • Point out any areas we must not close
  • Let building users know which areas are affected

Advice

Upper Green: questions and answers

Do you cover business parks and estates near Upper Green, such as Stype Business Centre?

Yes. Estates, retail parks and business parks around Upper Green, Stype Business Centre among them, are all within reach. Photos and a short description are enough for a first look.

Do we have to stop operations in Upper Green while the joints are sealed?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.

Is Upper Green in your area?

Yes. Upper Green falls within our area, and you can call 01277 525 020 or send photos by email to get started.

Why is there a gap next to the joint filler?

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.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

When can forklifts run over new joint filler?

Cure times vary with the product and the conditions. We will give you a time for each zone when we agree the phasing.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Surface by surface

Semi-rigid joint fillers

If a joint is still opening, a semi-rigid filler may part from one face. That is normally dealt with by topping up later and we’ll flag it at quote stage.

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.

How the quote is worked out

The price varies from site to site. It mainly depends on:

  • The product specified
  • Travel to remote or island sites
  • Any access equipment needed
  • Backing rod, priming and other preparation

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

What we need to price the job

Whether it’s one area or a whole building, these details speed things up:

  • Drawings or a marked-up plan, if available
  • When you need the work done
  • The postcode of the building
  • Whether an asbestos survey exists

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, speak to us on 01277 525 020 or email us.

Joints that move: notes for Upper Green

Upper Green is about 60 miles from central London. Warehousing clusters around the motorways that ring and radiate from London. 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 where de-icing salt is spread in winter, open joints let it in.

For a school such as Inkpen Primary School, playground and building joints can be done in the holidays.

After the work

Once the work is signed off, a little attention goes a long way:

  • Allow for topping up joints as a new slab settles
  • Respect the cure time before traffic returns
  • Stop forks and pallets being dragged across joints
  • Check joint lines on busy aisles regularly

Young concrete carries on shrinking, so some fillers part slightly from one face. It is a known trait of new floors and a later top-up deals with it in the majority of cases.

Grit in an open joint does damage every time a wheel crosses it. Filling it ends that cycle while it is still a straightforward job.
