Industrial and floor joint sealing
Floor joints in warehouses, factories, loading bays, industrial units and showrooms filled or sealed with the right product for the traffic and the movement.
- Joint edges chipping and breaking under forklift wheels
- Open joints collecting grit, dust and debris
- Old filler that has shrunk, cracked or come out

What industrial and floor joint sealing covers
Concrete floors in warehouses and industrial units are laid with joints to control cracking: saw-cut induced joints, and construction joints where one pour meets the next. Left open, or filled with a product that has failed, those joints collect grit and debris, and the unsupported edges break away under forklift and pallet-truck wheels. The damage grows with every pass, and it jolts loads and wears equipment. We fill and seal floor joints in warehouses, factories, loading bays, industrial units, and retail and showroom floors. The product depends on what the joint does. A semi-rigid filler is common in trafficked industrial joints because it supports the edges under hard wheels; a flexible sealant suits joints where movement is larger. We look at the traffic and the movement before recommending either, and we’ll tell you if the edges need repairing first, so the filler isn’t asked to bridge broken concrete.
We work across South East England, Greater London and all of Scotland. Our workmanship carries a 12-month guarantee, we’re CHAS accredited and a Constructionline member, and our applicators hold CSCS cards.

How it works
- Send details of the floor area, the type of traffic, photos of joint damage and any zones that must stay in use.
- We assess joint condition, movement and edge damage, and recommend the right filler or sealant for the traffic.
- You receive a fixed quote, with phasing set out if the floor must stay operational.
- Old filler and debris are removed and the joints cleaned back to sound concrete.
- Joints are filled or sealed and finished flush with the floor so wheels run across smoothly.
- Each phase is handed back once the product has cured enough to take traffic.
Semi-rigid or flexible?
Hard-wheeled forklifts and pallet trucks need joints that support the concrete edges, which is why semi-rigid fillers are common in trafficked industrial floors. They accommodate little movement, so on joints that are still opening, timing and product choice matter. Where movement is larger, a flexible sealant may be the better option. We recommend the right filler or sealant for the traffic and movement after looking at the floor.
Keeping the floor working
Few warehouses can close an entire floor. Phased work can be planned so areas stay in use, working aisle by aisle or bay by bay, with sections coned off while the product cures. Tell us your site hours, busy periods and access windows and we’ll plan around them. Racking aisles, goods-in and dispatch areas can be scheduled separately, so the parts of the floor that matter most on a given day stay open.
When the edges are already broken
Filling a joint whose arrises have spalled leaves the filler unsupported, and it soon fails. We’ll tell you if the edges need repairing first. Edge repair is a separate job, and the quote will make clear what is and isn’t included. Sealing first and repairing later rarely works, because the broken edges keep loosening the new material.
Beyond the floor
Floors are only part of the picture in a warehouse or factory. Cladding panel joints, loading bay surrounds and movement joints in block walls also fail over time, and gaps around services in fire-resisting walls between units or office areas may need fire-rated sealant where it is specified. We can look at those on the same visit and quote them alongside the floor, so one contractor covers the sealant across the building.
Why it’s worth doing now
Open or failed floor joints let wheels hit the joint edges. Each impact chips a little more off the arris until the joint is wide, broken and shaking trucks and loads. Filling or sealing joints for the traffic they carry protects the slab, the equipment and the people driving it.
What affects the quote
We don’t publish set prices, because no two buildings are the same. Send details and we’ll give you a fixed quote before we start. The main things that affect it are:
- How many metres of joint there are, and how many areas, elevations or sites
- How much failed sealant has to come out, and how hard it is
- Joint size, depth and whether backing rod or primer is needed
- Access: height, scaffold or MEWP access arranged by others, occupied areas
- The product the joint needs (and colour, where it matters)
- Programme, phasing and site requirements such as permits and inductions
What a good quote includes
- All failed sealant removed, never sealed over
- The product named for each joint type
- What the 12-month guarantee covers
- When each area can be used again
- Who is doing the work, their CSCS cards and the insurance in place
- What site paperwork and records are included
Aftercare
Sweep joints regularly so grit doesn’t pack in, and report chipped edges or loose filler early. Where traffic routes change, check the joints on the new route. Young slabs keep shrinking for a while, so joints may need topping up after the first year or so.

Industrial and floor joint sealing: common questions
How soon can traffic go back over the joints?
That varies with the product and the temperature. Before work starts, we’ll tell you how long each phase needs before wheels go back on it.
Can you work while the warehouse is operating?
Yes, in phases. Areas being treated are closed off while the rest of the floor stays in use.
Do you repair broken joint edges?
We’ll tell you if the edges need repairing before filling, and the quote will make clear what is included.
Why not fill every joint with a flexible sealant?
Under hard wheels, a soft sealant gives the edges little support, so they can still break away. Semi-rigid fillers are common for that reason.
Are shop and showroom floors included?
Yes. Retail and showroom floors have joints too, usually under lighter traffic, and the product is chosen to suit.
Do you give a fixed price before you start?
Yes. Send photos, drawings or a joint schedule, or we can visit, and we’ll give you a fixed quote with the scope in writing before any work starts.
Are you accredited and insured?
Yes. We’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry £5m public liability insurance.
