Floor joint sealing in The Flints

A working floor can rarely be closed for days on end, so we phase the work aisle by aisle or bay by bay. Share your site hours and access windows and the programme is built around them, with goods still moving in the areas we aren’t in. Site teams most often ask us about loading bay joints breaking down and broken arrises where pallet trucks cross, on saw-cut induced joints, retail and showroom floors and loading bays. A single leaking joint is often how a building in The Flints first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places such as The Flints, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

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. That’s why many clients bring in a specialist from the beginning.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

The Flints: questions and answers

Is The Flints off your patch?

No. Places such as The Flints are covered as much as the big towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you work at a site such as Butterfield Business Park, by The Flints?

Yes. We cover The Flints and the area around it, including industrial estates, business parks and retail parks such as Butterfield Business Park. Send details of the unit and the work through our quote form for a quick quote.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Why is there a gap next to the joint filler?

It can be shrinkage, contamination on the joint faces or a product unsuited to the movement. We look at which it is before recommending anything.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators.

How long does a typical visit take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Level or flatness problems across the floor
  • Structural cracking in the slab
  • A floor that rocks at the joints, which needs a structural fix

If in doubt, call the office on 01277 525 020 or email drawings and photos and we will say what we think.

Where we work in The Flints

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

Keeping the joints sound

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

  • Record damaged joints with a photo and a location
  • Respect the cure time before traffic returns
  • Mention any aggressive cleaning regime at quote stage
  • Treat loading bay joints first if they’re failing

Ask drivers not to drag forks or pallets along the floor. Even a well-filled joint can be damaged by steel scraping along it if it keeps happening.

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.

Owners, agents and contractors

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in The Flints can sit alongside others in a wider programme.

Floors, slabs and movement joints in The Flints

The Flints sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint. The Flints is about 32 miles from central London. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day.

On a site such as Butterfield Business Park, which lies south-west of The Flints, the movement joints are in car park slabs, paving and building elevations. Hospitals like Keech Hospice Care (3.7 miles west of The Flints) have multi-storey or surface car parks whose joints carry vehicles round the clock. Schools like Offley Endowed Primary School often have long brick elevations with movement joints that age quietly.

The Flints is about 4 miles south-west of Hitchin, in Hertfordshire. We send applicators to The Flints for floor joints, handled exactly as we handle every other area. The Flints is one of 371 places in Hertfordshire on our list. For work in that direction, see our London page.

Nearby towns on our patch include Hemel Hempstead (13 miles south), Stevenage (7 miles east), St Albans (12 miles south), Welwyn Garden City (11 miles south-east), Harpenden (8 miles south) and Hitchin (4 miles north-east).

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a day or more, depending on the metres of joint and how many zones the floor is split into, and we clear our waste as we work. If others near The Flints need work, visits can be combined. You will have a fixed quote before work starts.

  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. We fill the joints with the agreed product, finished level.
  5. Each area is handed back when ready for traffic.

Getting the site ready

  • Arrange parking or a loading space
  • Move anything stored against the joints
  • Flag any permit to work we will need
