How we handle floor joint sealing in Gadshill

Most industrial slabs are divided into panels by saw-cut joints and construction joints, and every one of those joints is an exposed edge under hard wheels. Our job is to put the right filler or sealant into them for the loads and the movement they see, so the arrises are supported and grit stays out. Site teams most often ask us about open saw cuts full of debris and brittle joint filler breaking up, across saw-cut induced joints, loading bays and retail and showroom floors. Most enquiries from Gadshill start with one failed joint and grow into a wider look at the building: 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 Gadshill, floor joints are often in barns and farm buildings turned into workshops, stores and offices. 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. The promise is simple: if our work fails within that year, we put it right.

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, 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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Leave it or put it right?

Holding off until the whole floor can close can take a long time. Zone by zone, the worst aisles can be dealt with now and the remainder follows on a plan that suits you. Converted and older buildings near places like Gadshill tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Different surfaces, different methods

Flexible floor sealants

Polyurethane sealants suit floor joints with larger movement. They give less edge support than semi-rigid fillers so they are used where movement matters more than wheel load.

Isolation joints at walls and columns

Isolation joints separate the slab from walls, columns and plinths so it can move independently. A flexible product suits them better than a stiff filler.

What affects the price in Gadshill

Quotes vary with the job. It mainly depends on:

  • The product specified
  • How much existing material needs removing
  • Location, for remote and island sites
  • Whether the work must be split into stages

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Sending details for a quote

Good information means a firmer quote. When you get in touch, include:

  • Any dates the work must fit around
  • What the building is and how it’s used
  • A wide shot and a close-up of the area
  • The product your specification calls for

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or send details through our quote form if you’d rather talk the job through.

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Put loading bays at the top of the list
  • Record damaged joints with a photo and a location
  • Let us know what the floor is cleaned with
  • Keep trucks off new joints until we say they’re ready

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

While the concrete edges are intact, it’s a filling job. After the edges go, repairs come into it, with more downtime and more disruption.

Our process

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Gadshill are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. A floor survey records every joint, its edges and what crosses it.
  2. You receive a fixed quote showing products and phasing.
  3. Old fill and packed debris come out until both faces are sound.
  4. Dust is vacuumed out and primer applied where specified.
  5. Filler or sealant is placed to depth and finished flush.
  6. Zones reopen once cured and the work moves on.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Tell staff and tenants when we will be in
  • Send any specification or drawings in advance

Gadshill: questions and answers

Is a smaller place like Gadshill outside your area?

Not at all. Gadshill is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Would you work within a site like French Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Which is better for warehouse joints, filler or sealant?

We decide joint by joint. Hard wheels need edge support, which points to a semi-rigid filler and perimeter or movement joints need flexibility. You’ll see the choice for each area in the quote.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. 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. We don’t remove asbestos-containing materials.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Who decides which product is used?

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

Floor joint sealing in Gadshill: the local picture

The South East is one of the drier parts of the UK. External joints still wait for dry conditions, while winter salting gets into any joint left open.

That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

At places like Strood Retail Park, 1.8 miles to the south-east of Gadshill, joints are sealed a section at a time so operations carry on. For estates staff at a university like University for the Creative Arts - Rochester, 3.1 miles south-east of Gadshill, building and paving joints are part of the planned maintenance list. Large sites such as French Hospital (2.4 miles south-east of Gadshill) have car parks, service roads and long elevations with movement joints in brick and panels.
