Why deal with it now?
A floor coating laid over open joints soon cracks along the joint lines. Joints need their own treatment, whether or not the floor is coated. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
A quote for floor joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

Floor joint sealing in Castle Green
Concrete floors in warehouses and factories are cut into bays with saw cuts and day 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 arrises are supported and grit stays out. We work on loading bays, saw-cut induced joints and forklift and pallet-truck routes, and the usual reasons a site gets in touch are flexible sealant torn out by wheels and drivers complaining about joints on a route. Whoever orders the work in Castle Green, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. Planning a job in Castle Green means thinking about access, loading times and the ULEZ as well as the joints.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Photograph any joint that starts to chip
- Expect fillers on young slabs to need a top-up
- Remind operators to lift rather than drag
- Keep trucks off new joints until we say they’re ready
We will give you a time before trucks can run over the new joints, and it’s worth enforcing. In a busy building, barriers keep early traffic away.
Every day an open joint stays full of grit, the edges take more punishment. Getting it filled stops the damage before it becomes a repair.

Common problems we fix in Castle Green
A soft, flexible sealant on a forklift route can’t hold the arrises up and the edges fail regardless. It can go the other way too: a rigid fill in a joint that is still opening cracks or debonds.
Look out for the following:
- Joint fill separating from the concrete
- Untidy open joints in a retail unit
- Old filler gone hard, cracked or loose
- Drivers complaining about joints on a route
For an estate such as Barking Community Hospital, 1.1 miles west of Castle Green, the joints in ramps, decks and long building elevations all need attention over time.

On site: what to expect
Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. In Castle Green, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First, the zones and order of work are agreed with you.
- We point out joints whose edges need repairing first.
- We clear each run back to clean concrete.
- The chosen filler or sealant goes in flush with the slab.
- Each area is handed back when ready for traffic.
Preparing the site
- Let building users know which areas are affected
- Have the specification and drawings to hand
- Agree which areas must stay open

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Surface by surface
Forklift and pallet-truck routes
A route joint has to take repeated wheel strikes without breaking up. Wheel type and traffic level steer the product choice.
Flexible floor sealants
Flexible floor sealants come in several colours so ask if the colour matters.

Castle Green: questions and answers
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Can you work on a hospital site such as Barking Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Do you work in Castle Green?
Yes. We take on work across Castle Green.
How long before trucks can use the joints?
Cure times vary with the product and the conditions. You’ll get a reopening time for each area when we agree the phasing.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Can you work to our specification?
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.
