Floor joint sealing in Charter Alley

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

Different surfaces, different methods

Construction joints

Construction joints, sometimes called day joints, mark where one pour ended and the next began. They often see more movement than sawn joints, and that shapes the product choice.

Semi-rigid joint fillers

For trafficked warehouse joints, semi-rigid fillers are common. They are installed to the depth the manufacturer specifies and finished flush.

How we handle floor joint sealing in Charter Alley

Concrete floors in warehouses and factories are cut into bays by saw-cut joints and construction joints, and every one of those joints is an exposed edge under hard wheels. We fill or seal them with a product matched to the traffic and the movement so the edges are held up and debris can’t pack in. We work on joints along racking aisles, saw-cut induced joints and construction joints, and the failures we’re asked to look at most are brittle joint filler breaking up and trucks and loads jolting over damaged joints. A specialist sealant contractor works differently from a general builder: on jobs in Charter Alley, preparation and product choice get the time they need.

In and around smaller places like Charter Alley, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Why deal with it now?

Duct tape or a general builders’ sealant can seem to buy some time. None of it is designed for wheel loads and traffic soon pulls it out. The right filler or sealant saves doing it twice. One visit to deal with every failing joint makes more sense than several trips to a place like Charter Alley, rather than one at a time. Photos of every joint help us quote for the whole job.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What you get with us

  • Fully insured, including public liability cover
  • One number for every site we cover
  • A Constructionline member, so easy to vet
  • Fixed quotes based on photographs, drawings or a visit

Honest limits

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Structural cracking in the slab
  • Level or flatness problems across the floor
  • Unstable slabs moving under traffic

If in doubt, speak to us on 01277 525 020 or send details through our quote form and we’ll say what we think.

What we seal

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

FAQs: Charter Alley

Does your area include sites such as Berry Court Business Park, near Charter Alley?

Yes. Our area takes in Charter Alley and its surroundings, with estates and business parks such as Berry Court Business Park included. Send details of the unit and the work through our quote form for a quick quote.

Is a hospital such as Parklands Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

When can forklifts run over new joint filler?

Cure times vary with the product and how cold the slab is. You’ll get a reopening time for each area when we agree the phasing.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Do you hold CHAS accreditation?

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

What we’re called out for in Charter Alley

Pallet-truck and forklift wheels concentrate weight on a tiny contact patch. Where a joint is open, the wheel dips and strikes the far edge, and repeated impacts break the concrete away.

Look out for the following:

  • Chipped and spalling edges along forklift routes
  • Saw-cut joints left open and packed with grit
  • A gap opening alongside old joint filler
  • Cracked and crumbling joint fill

For buildings at a park such as Berry Court Business Park, 1.7 miles to the north-east of Charter Alley, brick and panel movement joints are easy to forget until one leaks.

What to look for in a quote

  • Whether old or failed sealant will be cut out, not overlaid
  • How the joint faces will be prepared and primed
  • Are they CHAS accredited or on Constructionline?
  • Can the work be phased to keep areas open?

Our contractor checklist

From enquiry to sign-off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes between a day and a number of days, set by the joint lengths, the edge condition and the phasing you need, and we clear our waste as we work. For work around Charter Alley, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  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. We tell you when each zone can carry trucks again and move on to the next.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Point out parking and an unloading spot
  • Warn occupants and staff about the work
