About our floor joint sealing in The Platt

Open joints take a beating from forklift and pallet-truck wheels. Each crossing knocks the unsupported edge until a crisp saw cut becomes a wide, broken groove. Filling the joint properly gives the edges back their support, which is kinder to trucks, loads and operators. If you have sealant pulled out along a truck route and old filler gone hard, cracked or loose, we can put it right, whatever the surface. A single leaking joint is often how a building in The Platt 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.

For a site near The Platt, measurements and photos up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

  1. We agree the traffic routes and phasing with your site team.
  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. You get a time for each zone to reopen.

Common questions from The Platt clients

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

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you cover business parks and estates near The Platt, such as Durgates Industrial Estate?

Yes, sites like Durgates Industrial Estate are within our area, along with the rest of The Platt. To start, just call the office on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Are you fully insured?

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

Will we need to close the floor?

We phase it. We work aisle by aisle or zone by zone so the rest of the floor stays in use around the site hours and access windows you give us.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Why is there a gap next to the joint filler?

Separation normally comes from slab shrinkage, poor preparation or the wrong product. We look at which it is before recommending anything.

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.

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

How the job changes by surface

Construction joints

Day joints vary, with or without armoured edges. If the edges look unsound, we will say so before any filling is done.

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.

Keeping the joints sound

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

  • Allow for topping up joints as a new slab settles
  • Remind operators to lift rather than drag
  • Record damaged joints with a photo and a location
  • Treat loading bay joints first if they’re failing

Dragged forks and pallets gouge joints and edges alike. Steel tines will mark a good joint over time.

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.

Warehouse floors and decks around The Platt

The Platt is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints. At about 33 miles from central London, The Platt is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

Schools like Frant Church of England Primary School often have long brick elevations with movement joints that age quietly. Hospitals like Tunbridge Wells Homeopathic Hospital (3.4 miles north of The Platt) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Cost factors for floor joints

Quotes vary with the job. It mainly depends on:

  • Working within restricted access windows
  • Backing rod, priming and other preparation
  • The total length or number of joints
  • Site requirements such as inductions and permits

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote when you are ready.

What we need to price the job

There’s no need for a formal survey. A few details are enough to get going:

  • Whether the building will be occupied during the work
  • When you need the work done
  • Approximate linear metres or a joint schedule
  • Whether an asbestos survey exists

Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, speak to us on 01277 525 020 or send details through our quote form.

When to call us in The Platt

Soft sealant in a heavily trafficked joint gives the edges little support, so the concrete still breaks beside it. The opposite mistake happens as well: a rigid fill in a joint that is still opening cracks or debonds.

Common reasons buildings call us in:

  • Dock area joints that have failed first
  • A rough ride across broken joints
  • Soft sealant dragged out of trafficked joints
  • Open saw cuts full of debris

University campuses such as Canterbury Christ Church University - Salomons, 4.9 miles to the north of The Platt, have car parks, paved walkways and building elevations with movement joints.

What to look for in a quote

  • Can the work be phased to keep areas open?
  • How joint depth will be controlled
  • Whether old or failed sealant will be cut out, not overlaid
  • How they handle RAMS and site documents
