Floor joint sealing for Knave's Ash sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Surface by surface

Loading bays and dock areas

Flexible floor sealants

Polyurethane floor sealants are available in a range of colours, and we’ll confirm what the specified product offers.

How we handle floor joint sealing in Knave's Ash

Across Knave's Ash and the rest of Kent, it runs the same way: 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, loading bays and joints along racking aisles, and the failures we are asked to look at most are untidy open joints in a retail unit and trucks and loads jolting over damaged joints. Facilities teams, main contractors and managing agents in Knave's Ash tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Halls, schools and small commercial buildings near places like Knave's Ash have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Knave's Ash are normally planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
  2. The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
  3. We remove failed material and packed debris until sound concrete is exposed on both faces.
  4. We vacuum each run and prime it if the chosen product requires a primer.
  5. We fill each joint to depth and finish it flush so wheels roll straight across.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

What we need from you

  • Send any specification or drawings in advance
  • For older buildings, check the asbestos register before work
  • Agree which areas must stay open

Advice

Knave's Ash: questions and answers

Can you work on a hospital site such as Queen Victoria Memorial Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Does your area include sites such as Chislet Business Park, near Knave's Ash?

Yes. We cover Knave's Ash and the area around it, including industrial estates, business parks and retail parks such as Chislet Business Park. To start, just call the office on 01277 525 020 or email us with the unit, the joints involved and your access times.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

What information helps you price floor joint sealing?

A rough joint length, a few photos and a site plan are normally enough for a quick quote. We can visit where that helps, and you can phone 01277 525 020 or email a schedule or drawings to arrange it.

When can forklifts run over new joint filler?

Cure times vary with the product and the conditions. You’ll get a reopening time for each area when we agree the phasing.

Which is better for warehouse joints, filler or sealant?

The answer comes from the traffic and the joint’s movement. Forklift routes generally call for a semi-rigid filler that holds the arrises, while joints that move more take a flexible sealant.

What guarantee do you give on joint filling?

Every job has our 12-month guarantee. It covers our workmanship, not later slab movement or damage from impacts.

Floor joint sealing in Knave's Ash: the local picture

The sea is no more than about 3 miles from Knave's Ash. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so it pays to keep them sealed. Knave's Ash is about 55 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift.

A healthcare site such as Queen Victoria Memorial Hospital, 2.4 miles north of Knave's Ash, depends on car parks, ramps and service yards whose joints take traffic all day. Schools like Hoath Primary School often have long brick elevations with movement joints that age quietly. University campuses such as University of Kent (to the south-west of Knave's Ash) have car parks, paved walkways and building elevations with movement joints.

Commercial clients in Knave's Ash

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Why it’s worth doing now in Knave's Ash

Not every joint needs stripping out completely. If old material is sound on one face and only a fine gap has opened, it may not all have to come out, and we will say which joints need what. Converted and older buildings near places like Knave's Ash tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

When to bring in a specialist

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. That’s why many clients bring in a specialist from the beginning.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What sets the cost

A fixed quote reflects the actual work. It allows for:

  • How accessible the joints are
  • Working within restricted access windows
  • The product specified
  • How much there is to seal

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Sending details for a quote

A few photographs plus some basic facts will normally do. It helps to include:

  • What the building is and how it’s used
  • Your programme or deadline
  • Whether an asbestos survey exists
  • Drawings or a marked-up plan, if available

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, speak to us on 01277 525 020 or use the quote form.
