How we handle floor joint sealing in Throwley

Sometimes the concrete either side of a joint has already spalled. A filler laid against broken edges has nothing sound to grip, so we will tell you if the joint edges need repairing first and explain how it affects the programme. If you’re dealing with old filler gone hard, cracked or loose and filler that has parted from one face, we can put it right, on loading bays, joints along racking aisles and retail and showroom floors alike. For commercial sealant work in Throwley, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In and around smaller places like Throwley, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Do you need floor joint sealing in Throwley?

Unfilled joints soon pack with grit, shrink-wrap scraps and pallet splinters. That debris is hard and levers at the edges as wheels pass, speeding up the damage.

Clients usually get in touch after noticing one or more of the following:

  • Dock area joints that have failed first
  • Flexible sealant torn out by wheels
  • Unfilled floor joints collecting dirt and grit
  • Chipped and spalling edges along forklift routes

In and around Throwley, the right filler or sealant for each joint depends on the traffic and the movement it takes.

Before you book anyone

  • Are they CHAS accredited or on Constructionline?
  • Who will actually carry out the work
  • The terms of the workmanship guarantee
  • Will failed sealant be removed rather than covered?

Questions to ask before you appoint anyone

Cost factors for floor joints

To price the job, we consider:

  • Access and working height
  • Location, for remote and island sites
  • Working within restricted access windows
  • How much existing material needs removing

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 fixed quote when you are ready.

Before you send an enquiry

We can often quote from photos and a few details. It helps to include:

  • Drawings or a marked-up plan, if available
  • Asbestos survey details if the building is older
  • The product your specification calls for
  • Your programme or deadline

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or use the quote form with what you know.

Questions we’re asked in Throwley

What paperwork can you provide for a job in Throwley?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Will our site in Throwley have to close for joint sealing?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Do you work in Throwley?

Yes. We take on work across Throwley, and the same phone number covers every area.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators.

What the job involves on each surface

Retail and showroom floors

We plan shop-floor work so trading can continue. Give us your opening pattern and access windows and the phasing follows.

Isolation joints at walls and columns

We plan column and wall joints around racking and fixed plant.

Traffic, movement and joints around Throwley

Throwley 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 where de-icing salt is spread in winter, open joints let it in. Throwley is about 44 miles from central London. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift.

A joint near Throwley that has lost its sealant lets in water and grit, and the edges suffer next; we’ll tell you if the edges need repairing first.

Throwley is about 4 miles south of Faversham, in Kent. Throwley sits inside our coverage and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. Throwley is one of 931 places in Kent on our list for floor joints. For work in that direction, see our London page (44 miles or so).

Looking after the joints

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

  • Make joint checks part of your floor inspections
  • Sweep debris out of open joints until they can be filled
  • Keep photos of joints that look like they’re failing
  • Mention any aggressive cleaning regime at quote stage

Young concrete carries on shrinking, so some fillers part slightly from one face. That is common and is normally dealt with by topping up once the slab has settled down.

Joint damage starts slowly and then speeds up. Once the first piece is out, wheels drop further and hit harder, so it pays to act at the first signs.

Doing it in-house

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
