How we handle floor joint sealing in Pitshanger

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 retail and showroom floors, saw-cut induced joints and loading bays, and what we’re called in for most is flexible sealant torn out by wheels and loading bay joints breaking down. Whether you call it commercial sealant work, mastic application or joint sealing, in Pitshanger it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Areas such as a loading bay or car park deck in Pitshanger normally have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Doing it in-house

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:

  • Broken concrete either side of the joint
  • Worn screed or surface finishes
  • Slab panels that rock or move under load

Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

How a job runs

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  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. Zones reopen once cured and the work moves on.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Move anything stored against the joints
  • Have the specification and drawings to hand

Advice

Looking after the joints

After handover, these steps help:

  • Tell us about strong cleaning chemicals before we quote
  • Expect fillers on young slabs to need a top-up
  • Photograph any joint that starts to chip
  • Make joint checks part of your floor inspections

We will give you a time before trucks can run over the new joints, and it’s worth enforcing. Cones or barriers stop the first driver cutting the corner.

Joint damage starts slowly and then speeds up. Each chip makes the drop deeper and the next impact harder so early treatment saves a lot of trouble.

What happens if it’s left?

A floor coating laid over open joints soon cracks along the joint lines. The joints have to be filled or sealed as joints, whether or not the floor is coated. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

A quote for floor joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

Why us?

  • Work to your specification and the manufacturer’s guidance
  • Public liability insurance in place
  • Work carried out by CSCS-carded applicators
  • CHAS accredited contractor

Traffic, movement and joints around Pitshanger

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. Pitshanger has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Phasing is what makes joint work possible on busy sites such as Manor House Business Park (0.9 miles north-east of Pitshanger): one bay, aisle or car park row at a time. For estates staff at a university like University of West London (1 mile south of Pitshanger), building and paving joints are part of the planned maintenance list.

Pitshanger is about 1 mile north of Ealing, in Greater London. Across the W5 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

Signs you need floor joint sealing in Pitshanger

A soft, flexible sealant on a forklift route can’t hold the arrises up, so the concrete still breaks beside it. The opposite mistake happens as well: a stiff filler in a joint that keeps moving splits or comes away from the sides.

Common reasons buildings call us in:

  • Cracked and crumbling joint fill
  • Chipped and spalling edges along forklift routes
  • Saw-cut joints left open and packed with grit
  • Soft sealant dragged out of trafficked joints

For buildings at a park such as Manhattan Business Park, 0.7 miles to the north-east of Pitshanger, brick and panel movement joints are easy to forget until one leaks.

How to choose a sealant contractor

Questions about Pitshanger

Can you take on a job at a hospital such as Cygnet Hospital Ealing?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Can you cope with the access rules in a London building?

Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Do you offer coloured sealant?

It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Should floor joints be filled or sealed?

We decide joint by joint. Where hard wheels cross, a semi-rigid filler is typically right, and movement joints or perimeters need something flexible. The quote sets out what goes where.

Will you just go over the old sealant?

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

How long before trucks can use the joints?

The wait is set by the product’s cure time, and cold floors slow it down. Phasing is planned with that in mind.
