Floors, slabs and movement joints in Grafty Green

Grafty Green 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 where de-icing salt is spread in winter, open joints let it in. At about 39 miles from central London, Grafty Green is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London.

Schools such as Platts Heath Primary School have movement joints in their walls and floors that are easy to overlook. Business parks such as Roebuck Business Park, 2.3 miles north of Grafty Green, have car parks, paved areas and long brick and panel elevations, all with movement joints.

Grafty Green is about 8 miles south-east of Maidstone, in Kent. Grafty Green sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. 931 places across Kent fall within our area, Grafty Green among them.

How we handle floor joint sealing in Grafty Green

Floor joint sealing for us covers warehouse aisles, loading bays, production halls, retail floors and showroom slabs. Each job is priced from the metres of joint, their condition and the access windows we get and the figure is fixed before work begins. We work on loading bays, construction joints and retail and showroom floors, and what we’re called in for most is joint edges breaking up under truck wheels and trucks and loads jolting over damaged joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Grafty Green it comes down to the same thing: the right product in a properly prepared joint.

For a site near Grafty Green, 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.

A 12-month guarantee applies to all our work in Kent. Should something we installed fail, give us a call on 01277 525 020 or use the quote form and we will come back to it.

Surface by surface

Semi-rigid joint fillers

For trafficked warehouse joints, semi-rigid fillers are common. We place them to depth and trim them level with the slab.

Loading bays and dock areas

We typically work through dock areas a few bays at a time so goods in and out carry on. Your site hours and access windows set the order.

What sets the cost

These are the things that shape the price:

  • How accessible the joints are
  • Specialist products, such as fire-rated or hygienic sealants
  • The size and state of each joint
  • Whether old sealant has to be cut out first

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • Whether the building will be occupied during the work
  • A wide shot and a close-up of the area
  • The product your specification calls for
  • Any dates the work must fit around

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or send photos by email.

Why deal with it now?

While the arrises are intact, filling a joint is straightforward. Wait until the edges have spalled and the concrete needs repairing before the joint can be filled which means more downtime in that zone. Halls, stores and units around places like Grafty Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why us?

  • Public liability insurance in place
  • Over 20 years of commercial sealing
  • 12-month guarantee on workmanship
  • Constructionline member

Grafty Green: questions and answers

Will you take on work at estates like Roebuck Business Park, close to Grafty Green?

Yes. Our area takes in Grafty Green and its surroundings, with estates and business parks such as Roebuck Business Park included. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Is Grafty Green too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

What do you need from us to quote?

Approximate metres of joint, photographs of typical and worst areas, and a floor plan are normally enough for a quick quote. We can visit where that helps so speak to us on 01277 525 020 or email a schedule or drawings to set one up.

Is it normal for joint filler to separate?

On newer slabs, the concrete keeps shrinking after the joints are filled and a stiff filler can separate down one side. It is typically dealt with by topping up.

Which is better for warehouse joints, filler or sealant?

The answer comes from the traffic and the joint’s movement. Trafficked joints on truck routes typically need a semi-rigid filler to support the edges, while joints that move more take a flexible sealant.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators.

On site: what to expect

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Rural sites near Grafty Green may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  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. The chosen filler or sealant goes in flush with the slab.
  5. Each area is handed back when ready for traffic.

What we need from you

  • Let building users know which areas are affected
  • For older buildings, check the asbestos register before work
  • Tell us what induction or permit system the site runs

Request a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Advice

Honest limits

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Broken concrete either side of the joint
  • Unstable slabs moving under traffic
  • Worn screed or surface finishes

If you’re not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Surfaces we seal

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

Common problems we fix in Grafty Green

Oil, laitance, dust and old cleaning chemicals build up inside joints. Without cutting back to sound, clean concrete, the new material simply lifts out.

These are often picked up first by site or facilities staff:

  • Soft sealant dragged out of trafficked joints
  • Filler that has parted from one face
  • Scruffy, dirty joint lines on a shop or showroom floor
  • Cracked and crumbling joint fill

Campuses like Canterbury Christ Church University (to the north of Grafty Green) mix old and new buildings, with movement joints wherever they meet.

Questions to ask before you book

  • Are they CHAS accredited or on Constructionline?
  • Is the sealant right for the movement and the substrate?
  • How long is the guarantee, and what does it include?
  • Their plan for phasing and protecting the area
