Floor joint sealing in Pottersheath

It isn’t only heavy industry. Shops, showrooms and trade counters have joints that take trolleys, foot traffic and scrubber-driers, and an open, grimy joint line looks poor as well as catching wheels. A neat, flush fill makes the floor easier to clean and look after. We work on retail and showroom floors, loading bays and construction joints, and the failures we’re asked to look at most are brittle joint filler breaking up and filler that has parted from one face. One point of contact handles commercial sealant work in Pottersheath from the first photographs to the final walk-round, whether it’s one building or several.

For a site near Pottersheath, measurements and photographs up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

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 spell out the cover before we begin.

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Put loading bays at the top of the list
  • Allow for topping up joints as a new slab settles
  • Keep grit out of unfilled joints in the meantime
  • Let us know what the floor is cleaned with

Ask drivers not to drag forks or pallets along the floor. Even a well-filled joint can be damaged by steel scraping along it if it keeps happening.

Edges tend to break slowly at first, then quickly. Once the first piece is out, wheels drop further and hit harder so early treatment saves a lot of trouble.

Common questions from Pottersheath clients

Is Pottersheath too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Does your area include sites such as Arlington Business Park, near Pottersheath?

Yes, sites like Arlington Business Park are within our area, along with the rest of Pottersheath. To start, just call 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

How long does a typical visit take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Are your applicators CSCS-carded?

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

What the job involves on each surface

Semi-rigid joint fillers

On industrial routes, a semi-rigid filler is often the right choice. We place them to depth and trim them level with the slab.

Flexible floor sealants

Movement joints, joints at walls and joints in lightly trafficked areas often take a flexible sealant. Closed-cell backing rod goes in first, keeping the bead shallow and gripping only the two faces.

What happens if it’s left?

An open joint is a modest filling job while its edges are sound. Wait until the edges have spalled and the concrete needs repairing before the joint can be filled, with longer closures to match. Older rural buildings around Pottersheath move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Our process

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking 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 Pottersheath, 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. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
  3. Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
  4. Dust is extracted from the joint and primer applied where the manufacturer specifies it.
  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.

Before we start on site

  • Flag any permit to work we will need
  • Have the specification and drawings to hand
  • Point out any areas we must not close

Advice

Do you need floor joint sealing in Pottersheath?

Loading bay joints are exposed to wind, wet tyres and bigger temperature swings on top of the heaviest turning movements. They are often the first on a site to break down.

Most enquiries start with one or more of the following:

  • Old filler gone hard, cracked or loose
  • Failing joints at loading bays and dock doors
  • Flexible sealant torn out by wheels
  • Broken arrises where pallet trucks cross

A healthcare site such as Queen Elizabeth II Hospital, 4.7 miles south of Pottersheath, depends on car parks, ramps and service yards whose joints take traffic all day.

Comparing quotes

  • How the existing material will be dealt with
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their public liability cover
  • Whether their applicators hold CSCS cards

Our contractor checklist

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • Location, for remote and island sites
  • Induction, permit and paperwork requirements
  • Backing rod, priming and other preparation
  • Any access equipment needed

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Sending details for a quote

A few photos plus some basic facts will normally do. Please tell us:

  • The product your specification calls for
  • Your programme or deadline
  • Photos of the joints, close up and from further back
  • Drawings or a marked-up plan, if available

To get a fixed quote, ring 01277 525 020 or email us. You can also send details through our quote form.
