Floor joint sealing in Key's Green

For sites in Key's Green and across Kent, the process is short: you send details, we send a fixed quote, the joints are done and the 12-month guarantee follows. A rough length of joint, photos of the worst areas and a site plan let us give a quick quote and a visit can be arranged where that is easier. We work on forklift and pallet-truck routes, construction joints and loading bays, and the failures we are asked to look at most are dock area joints that have failed first and open saw cuts full of debris.

Jobs around smaller places like Key's Green are planned so the whole job is done in one visit. Note joint widths and the traffic that uses them, and we will take it from there.

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near Key's Green need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
  2. A fixed quote follows, listing the treatment for each area and the order of work.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
  5. We fill each joint to depth and finish it flush so wheels roll straight across.
  6. The area is handed back once it has cured enough to take traffic.

Getting the site ready

  • Warn occupants and staff about the work
  • Arrange parking or a loading space
  • Confirm the product named in the specification

Should maintenance staff do it?

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Slabs, ramps and loading bays in Key's Green

Rainfall across the South East, Key's Green included, is lower than in many parts of the UK. 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. Key's Green is about 32 miles from central London. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift.

For floors and slabs around Key's Green, the product is chosen for the traffic and the movement at each joint. Sites like Tunbridge Wells Hospital at Pembury (2.4 miles north-west of Key's Green) carry ambulances, deliveries and visitors’ cars over their road and deck joints.

FAQs: Key's Green

Is a smaller place like Key's Green outside your area?

No. Places such as Key's Green are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Can you take on a job at a hospital such as Tunbridge Wells Hospital at Pembury?

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

When can forklifts run over new joint filler?

The wait is set by the product’s cure time, and cold floors slow it down. We plan the phasing so that waiting time fits your operation.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

Is it normal for joint filler to separate?

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.

What guarantee do you give on joint filling?

There is a 12-month guarantee on our workmanship and the work is covered by public liability insurance.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

Maintenance after handover

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Start with the dock areas, where joints fail soonest
  • Hold traffic back until the product has cured
  • Keep grit out of unfilled joints in the meantime
  • Stop forks and pallets being dragged across joints

Once cured, the joints get cleaned along with the slab. Tell us about aggressive cleaning products or hot washing at quote stage so the product suits them.

Grit in an open joint does damage every time a wheel crosses it. Getting it filled stops the damage while it is still a straightforward job.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Spalled arrises, which need an edge repair first
  • Slab panels that rock or move under load
  • Cracks across panels caused by settlement or overload

If in doubt, ring 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

What we seal

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

Different surfaces, different methods

Saw-cut induced joints

A sawn joint left open soon packs with debris and chips at the edges. Filling them early keeps them tidy and protects the edges.

Retail and showroom floors

Retail joints see trolleys, footfall and scrubber-driers. The product is chosen for that traffic and the finish matters as much as the performance.

Cost factors for floor joints

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • The size and state of each joint
  • The total length or number of joints
  • The site’s rules and procedures
  • Distance, for remote addresses

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Before you send an enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • Clear photos of the problem areas
  • The asbestos register, for older buildings
  • The product your specification calls for
  • What the building is and how it’s used

Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, call the office on 01277 525 020 or email the details over.
