Floor joint sealing for Kennington sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • A floor that rocks at the joints, which needs a structural fix
  • A failing floor coating, which is a flooring contractor’s job
  • Structural cracking in the slab

If you’re not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Surfaces we seal

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

How we handle floor joint sealing in Kennington

We diagnose the floor first rather than guessing at a product: how wide the joints are, signs of ongoing movement, the wheel types crossing them and the state of the arrises. From that we choose between a semi-rigid filler and a more flexible sealant and the answer can differ from one zone to the next. The enquiries we see most involve failing joints at loading bays and dock doors and broken arrises where pallet trucks cross, on construction joints, joints along racking aisles and loading bays. Facilities teams, main contractors and managing agents in Kennington tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. When a joint fails, grit and water get in and the arrises start to break up.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. All of Greater London is in the ULEZ, and kerbside space in Kennington can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. First, the zones and order of work are agreed with you.
  2. We point out joints whose edges need repairing first.
  3. We clear each run back to clean concrete.
  4. The chosen filler or sealant goes in flush with the slab.
  5. You get a time for each zone to reopen.

Getting the site ready

  • Share your working hours and any access restrictions
  • Arrange parking or a loading space
  • Tell us which areas need to stay in use

Common questions from Kennington clients

Do you take on jobs in Kennington where loading and access are tightly controlled?

Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for

Is a hospital such as Gordon Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How long does a typical visit take?

It depends on the scope, but the work usually takes a day or more, depending on the metres of joint and how many zones the floor is split into. For bigger or phased jobs, we will set out a timescale with the quote.

Do you cover Kennington?

Yes. We cover Kennington and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. For a quote, call 01277 525 020 or use the quote form.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you have public liability insurance?

Yes. We’re fully insured, and the certificate can go with your quote.

Site staff or a sealant specialist?

Redoing a failed joint normally costs more than getting it right at the outset, 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.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Why deal with it now?

An open joint is a modest filling job while its edges are sound. Wait until the edges have spalled and the concrete needs repairing before the joint can be filled which means more downtime in that zone. Getting scaffold, permits or access booked in Kennington takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Aftercare for building managers

Problems stay small when the joints are checked regularly. Specifically:

  • Plan for a top-up on newer floors
  • Keep grit out of unfilled joints in the meantime
  • Treat loading bay joints first if they’re failing
  • Record damaged joints with a photo and a location

On younger slabs, a fine line can open down one side of a filled joint as the concrete keeps shrinking. It is a known trait of new floors and a later top-up deals with it.

A broken joint on a main route is crossed by every truck on that route. Early treatment protects wheels, loads and drivers as much as the floor.

What we’re called out for in Kennington

Left open, joints fill with grit, wrap and wood fragments. Packed debris acts like a wedge every time a wheel crosses so the arrises break sooner.

What tends to prompt an enquiry:

  • Joint edges breaking up under truck wheels
  • Loading bay joints breaking down
  • Cracked and crumbling joint fill
  • Trucks and loads jolting over damaged joints

Another example is Kennington Park Business Centre, under half a mile to the east of Kennington, where floors and yards would be done in stages around the occupiers.

What to look for in a quote

  • Their pre-qualification and accreditations
  • Will RAMS and insurance details be available?
  • How long is the guarantee, and what does it include?
  • Do they follow the manufacturer’s priming guidance?

Less than 3 miles from Kennington there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. London car parks, loading bays and podium decks often can’t close for long, so we seal in sections and hand areas back as each cures.

On a site such as Handel Business Centre (less than half a mile north-west of Kennington), the movement joints are in car park slabs, paving and building elevations.
