How we handle floor joint sealing in Hornchurch Marshes

Open joints take a beating from forklift and pallet-truck wheels. Every pass chips at the bare concrete edge, and over time a neat cut turns into a ragged channel. Filling the joint properly gives the edges back their support. It also smooths the route for drivers and stock. We work on saw-cut induced joints, loading bays and retail and showroom floors, and the failures we are asked to look at most are untidy open joints in a retail unit and old filler gone hard, cracked or loose. Facilities teams, main contractors and managing agents in Hornchurch Marshes tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Areas such as a loading bay or car park deck in Hornchurch Marshes typically have to stay in use. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Diagnose, treat, sign off

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before the next one starts. All of Greater London is in the ULEZ, and kerbside space in Hornchurch Marshes 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. Failed material and debris are removed and the joint cleaned.
  4. The chosen filler or sealant goes in flush with the slab.
  5. You get a time for each zone to reopen.

Before we start on site

  • Send your site hours and access windows
  • Flag any permit to work we’ll need
  • Arrange parking or a loading space

Common questions from Hornchurch Marshes clients

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

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it

Do you take on work at healthcare sites like Grays Court Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

What guarantee do you give on joint filling?

There is a 12-month guarantee on our workmanship, and we hold public liability insurance.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

How soon can traffic go back on the floor?

Cure times vary with the product and how cold the slab is. We’ll give you a time for each zone before we start.

Can you fill joints where the arrises have spalled?

Filling against broken edges doesn’t last. We’ll tell you if the joint edges need repairing first, so you can decide how to proceed.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

What sets the cost

These are the things that shape the price:

  • Any access equipment needed
  • Phasing around occupants
  • Travel to remote or island sites
  • The size and state of each joint

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Details that help us quote

However big the job, these details speed things up:

  • Clear photos of the problem areas
  • The product your specification calls for
  • The asbestos register, for older buildings
  • Rough lengths or quantities, or drawings if you have them

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or email drawings and photos.

Where floor joints take the most wear near Hornchurch Marshes

Hornchurch Marshes has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. 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.

On industrial estates such as Segro Industrial Park, which lies east of Hornchurch Marshes, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. For a centre such as Merrielands Retail Park (1.2 miles north-west of Hornchurch Marshes), the service yard and car park joints typically need attention first. For estates staff at a university like University of East London, 4.4 miles to the west of Hornchurch Marshes, building and paving joints are part of the planned maintenance list.

Doing it in-house

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.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Keeping the joints sound

Problems stay small when the joints are checked regularly. In particular:

  • Keep photos of joints that look like they’re failing
  • Walk the main routes and inspect joint lines on a regular cycle
  • Hold traffic back until the product has cured
  • Ask drivers not to drag forks or pallets

Keep traffic off fresh joints until the time we give you, 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 it pays to act at the first signs.

How the job changes by surface

Flexible floor sealants

Flexible floor sealants come in several colours, and we’ll confirm what the specified product offers.

Retail and showroom floors

In retail, joints take trolleys, castors and cleaning machines rather than forklifts. The product is chosen for that traffic and the finish matters as much as the performance.
