Common questions from Locksbottom clients

Can you work at a site such as Glebe Farm Business Park, by Locksbottom?

Yes. Our area takes in Locksbottom and its surroundings, with estates and business parks such as Glebe Farm Business Park included. Photos and a short description are enough for a first look.

Can you take on a job at a hospital such as Princess Royal University Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Is colour matching possible?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

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.

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 work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Is it normal for joint filler to separate?

On newer slabs, the concrete keeps shrinking after the joints are filled, so a semi-rigid filler can part from one face. It is normally dealt with by topping up.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

How we handle floor joint sealing in Locksbottom

Some joints reach us with their edges already broken. Filling against a crumbled arris won’t hold for long, so we’ll tell you if the joint edges need repairing first and leave that decision with you. If you’re dealing with a gap opening alongside old joint filler and dock area joints that have failed first, we can put it right, on loading bays, forklift and pallet-truck routes and saw-cut induced joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Locksbottom, that means joint design, primers and backing rod as standard.

Areas such as a loading bay or car park deck in Locksbottom usually have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When to bring in a specialist

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

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. For that reason, many FMs and contractors use a sealant specialist from the outset.

Our process

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. All of Greater London is in the ULEZ, and kerbside space in Locksbottom can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. A fixed quote follows, listing the treatment for each area and the order of work.
  3. We remove failed material and packed debris until sound concrete is exposed on both faces.
  4. Dust is extracted from the joint and primer applied where the manufacturer specifies it.
  5. The chosen product is placed to its specified depth and trimmed level with the floor.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

Before we start on site

  • Warn occupants and staff about the work
  • Agree which areas must stay open
  • Flag any permit to work we will need

Advice

How the job changes by surface

Saw-cut induced joints

Induced joints are sawn into a new slab to control where it cracks. They start narrow and widen as the concrete dries, and on truck routes they need a filler that supports the edges.

Construction joints

Day joints vary, with or without armoured edges. We will tell you if the edges or any armouring look like they need attention before filling.

Traffic, movement and joints around Locksbottom

At least three named trading, business or retail sites lie within about 3 miles of Locksbottom. Their warehouses, yards and car parks are exactly where joints take the most punishment. Basement car parks and service yards in London tend to be in use all working day, so the work is broken into short sections agreed with the building manager.

Another example is Chartwell Business Centre, 2.2 miles north-west of Locksbottom, where floors and yards would be done in stages around the occupiers. Office parks like Glebe Farm Business Park (2 miles south-west of Locksbottom) have decks, ramps and clad elevations whose joints take movement every day.

Locksbottom is about 2 miles south-west of Orpington, in Greater London. Our applicators travel to Locksbottom for work on floor joints, handled exactly as we handle every other area.

We also cover Crofton (1 mile east), Farnborough (1 mile south-east), Petts Wood (1 mile north-east), Bromley Common (1 mile north-west) and Keston (1 mile south-west) for floor joints. Bigger towns within reach include London (11 miles north-west), City of Westminster (14 miles north-west), Marylebone (14 miles north-west), Kensington (14 miles north-west), St Pancras (13 miles north-west) and Shoreditch (12 miles north-west).

After the work

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Keep photos of joints that look like they’re failing
  • Make joint checks part of your floor inspections
  • Sweep debris out of open joints until they can be filled
  • Keep trucks off new joints until we say they’re ready

Once cured, the joints get cleaned along with the slab. Tell us about aggressive cleaning products or hot washing at quote stage so we choose something that tolerates them.

Edges tend to break slowly at first, then quickly. Once the first piece is out, wheels drop further and hit harder, so it pays to act at the first signs.

What happens if it’s left?

Dirt and spillage gather in open joints, out of reach of the floor cleaner. In shops, showrooms and clean production areas that matters for hygiene and appearance. Flush, filled joints leave nothing for cleaners to dig out. In Locksbottom, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.

The price depends on 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.

What we’re called out for in Locksbottom

Small, hard wheels put a lot of load through a very small area. Where a joint is open, the wheel dips and strikes the far edge, and repeated impacts break the concrete away.

Site and facilities staff are often the first to spot these:

  • Drivers complaining about joints on a route
  • Open saw cuts full of debris
  • Filler that has parted from one face
  • Grimy joint lines spoiling a showroom floor

Hospital campuses such as Princess Royal University Hospital, under half a mile south of Locksbottom, grow in stages, leaving movement joints wherever new blocks meet old.

Questions to ask before you book

  • How they handle RAMS and site documents
  • Do they follow the manufacturer’s priming guidance?
  • How the existing material will be dealt with
  • Are they CHAS accredited or on Constructionline?
