About our floor joint sealing in Tonge Corner

A working floor can rarely be closed for days on end, so the work is split into zones and treated one area at a time. Share your site hours and access windows and the programme is built around them so the rest of the operation keeps going. We work on saw-cut induced joints, retail and showroom floors and construction joints, and the usual reasons a site gets in touch are cracked and crumbling joint fill and soft sealant dragged out of trafficked joints. One point of contact handles commercial sealant work in Tonge Corner from the first photos to the final walk-round, for single jobs and planned programmes alike.

Halls, schools and small commercial buildings near places like Tonge Corner have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

Our workmanship is guaranteed for 12 months, in Tonge Corner as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What we are called out for in Tonge Corner

Loading bay joints are exposed to wind, wet tyres and bigger temperature swings, as well as the tightest turning loads. They are often the first on a site to break down.

Look out for the following:

  • A rough ride across broken joints
  • A gap opening alongside old joint filler
  • Unfilled floor joints collecting dirt and grit
  • Loading bay joints breaking down

Hospital campuses such as Sittingbourne Memorial Hospital, 1.9 miles west of Tonge Corner, grow in stages, leaving movement joints wherever new blocks meet old.

Questions to ask before you appoint anyone

When something else is needed

We check first that sealant really is the fix. It won’t put right:

  • Spalled arrises, which need an edge repair first
  • Worn screed or surface finishes
  • Level or flatness problems across the floor

If in doubt, give us a call on 01277 525 020 or send photos by email and we’ll say what we think.

What we seal

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

On site: what to expect

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. Smaller jobs around Tonge Corner can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. The treatment and the zones are set out in a fixed quote.
  3. Old fill and packed debris come out until both faces are sound.
  4. Dust is vacuumed out and primer applied where specified.
  5. The joint is filled to its specified depth and trimmed level.
  6. We hand each phase back when it can take traffic.

Preparing the site

  • Share your working hours and any access restrictions
  • Warn occupants and staff about the work
  • For older buildings, check the asbestos register before work

Advice

Owners, agents and contractors

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

After the work

Keep the joints in good shape with a few simple steps:

  • Mention any aggressive cleaning regime at quote stage
  • Hold traffic back until the product has cured
  • Keep photographs of joints that look like they’re failing
  • Sweep debris out of open joints until they can be filled

We will give you a time before trucks can run over the new joints, and it’s worth enforcing. Cones or barriers stop the first driver cutting the corner.

A broken joint on a main route is crossed by every truck on that route. Early treatment protects wheels, loads and drivers as much as the floor.

Common questions from Tonge Corner clients

Is hospital work, at somewhere like Sittingbourne Memorial Hospital, something you do?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is a smaller place like Tonge Corner outside your area?

Not at all. Tonge Corner is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Do you use semi-rigid filler or flexible sealant on floor joints?

We decide joint by joint. Where hard wheels cross, a semi-rigid filler is usually right and perimeter or movement joints need flexibility. The quote sets out what goes where.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

Floors, slabs and movement joints in Tonge Corner

Schools like Lansdowne Primary School often have long brick elevations with movement joints that age quietly.

How the job changes by surface

Isolation joints at walls and columns

Joints around columns and along walls let the slab move without cracking against the structure. A flexible product suits them better than a stiff filler.

Flexible floor sealants

A flexible sealant suits perimeter and movement joints away from the heaviest traffic. Closed-cell backing rod goes in first, keeping the bead shallow and gripping only the two faces.
