Floor joint sealing for commercial buildings in Three Mills

Forklifts and pallet trucks are hard on open joints. Every pass chips at the bare concrete edge until a crisp saw cut becomes a wide, broken groove. A properly filled joint carries the wheel over and protects both arrises. It also smooths the route for drivers and stock. Most enquiries involve open saw cuts full of debris and dock area joints that have failed first, across loading bays, saw-cut induced joints and forklift and pallet-truck routes. A single leaking joint is often how a building in Three Mills first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Most London buildings can’t shut a car park, loading bay or warehouse floor for long. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

What affects the price in Three Mills

Quotes vary with the job. It mainly depends on:

  • The site’s rules and procedures
  • Location, for remote and island sites
  • Whether old sealant has to be cut out first
  • Which sealant the job calls for

The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

Sending details for a quote

It doesn’t need to be a full survey. These details are enough to start:

  • Clear photographs of the problem areas
  • Specification clauses that apply
  • How the joints are reached, and at what height
  • The site address and postcode

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Surface by surface

Loading bays and dock areas

At loading bays, product choice has to suit the loads, the temperature and the wet. Phasing is planned around your delivery schedule.

Saw-cut induced joints

Saw cuts are made soon after the slab is cast so shrinkage cracks follow a line. They are narrow but open up as the panels shrink so trafficked runs need a filler that holds the arrises.

Our process

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a day or more, depending on the metres of joint and how many zones the floor is split into, and we clear our waste as we work. For a job in Three Mills, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.

  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. We extract the dust and prime the faces if the product needs it.
  5. Filler or sealant is placed to depth and finished flush.
  6. We hand each phase back when it can take traffic.

What we need from you

  • Point out any areas we must not close
  • Make sure the joints can be reached
  • Arrange parking or a loading space

Advice

Your questions answered

Will you take on work at estates like Crescent Court Business Centre, close to Three Mills?

Yes, sites like Crescent Court Business Centre are within our area, along with the rest of Three Mills. To start, just call the office on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Can you take on a job at a hospital such as Mile End Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

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, flagging anything that needs clarifying.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

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

We decide joint by joint. Where hard wheels cross, a semi-rigid filler is normally right, and movement joints or perimeters need something flexible. You will see the choice for each area in the quote.

Can you phase floor joint work around operations?

We phase it. Areas are taken out of use a section at a time around the site hours and access windows you give us.

What site paperwork can you supply?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

When to call us in Three Mills

An ageing filler or sealant can go brittle and split especially under daily scrubbing and traffic. Once it has gone hard or come loose, it protects nothing.

Most enquiries start with one or more of the following:

  • Chipped and spalling edges along forklift routes
  • A rough ride across broken joints
  • Sealant pulled out along a truck route
  • Scruffy, dirty joint lines on a shop or showroom floor

For buildings at a park such as Crescent Court Business Centre (less than half a mile south-east of Three Mills), brick and panel movement joints are easy to forget until one leaks.

Comparing quotes

  • Whether old or failed sealant will be cut out, not overlaid
  • How they’ll work around occupants
  • Is the sealant right for the movement and the substrate?
  • Will RAMS and insurance details be available?

How to choose a sealant contractor

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Hold traffic back until the product has cured
  • Let us know what the floor is cleaned with
  • Treat loading bay joints first if they’re failing
  • Stop forks and pallets being dragged across joints

Ask drivers not to drag forks or pallets along the floor. Steel tines will mark a good joint over time.

Joint damage starts slowly and then speeds up. Each chip makes the drop deeper and the next impact harder, so it pays to act at the first signs.

London car parks, loading bays and podium decks often can’t close for long, which is why we work a few bays at a time.

What happens if it’s left?

Some runs only need partial renewal or topping up. If old material is sound on one face and only a fine gap has opened, it may not all have to come out and the quote shows which approach suits each run. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
