What we are called out for in Harbledown

When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way, so we check width and movement before quoting.

Site and facilities staff are often the first to spot these:

  • Spalled or broken joint edges in floors and decks
  • Expansion joints split through the centre of the bead
  • Rain penetration at brick or block movement joints
  • Previous reseals laid over old sealant

For an estate such as Kent and Canterbury Hospital (1.7 miles south-east of Harbledown), the joints in ramps, decks and long building elevations all need attention over time.

Before you book anyone

  • Proof of insurance
  • The named product and why it was chosen
  • Health and safety accreditation such as CHAS
  • Do they follow the manufacturer’s priming guidance?

How to choose a sealant contractor

How we handle expansion joint sealing in Harbledown

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side. A sealant suited to traffic and the expected movement goes in. We work on precast concrete panel joints, car park decks and ramps and blockwork control joints, and the usual reasons a site gets in touch are chipped joint edges on forklift routes and expansion joints filled with dirt and stones. Whether you call it commercial sealant work, mastic application or joint sealing, in Harbledown it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller community and commercial buildings around Harbledown have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Harbledown need work, visits can be combined. You will have a fixed quote before work starts.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Getting the site ready

  • Warn occupants and staff about the work
  • Tell us what induction or permit system the site runs
  • Move anything stored against the joints

Advice

How the job changes by surface

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors.

Concrete and precast panel joints

Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.

Looking after the joints

For the best life from the joints:

  • Clear dirt from joint lines during routine cleaning
  • Report split or peeling joint sealant early
  • Record the sealant used and the date in the O&M file
  • Put movement joints on the planned maintenance inspection round

In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. A sound seal keeps the joint working.

Questions we are asked in Harbledown

Is Harbledown too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Can you work on a hospital site such as Kent and Canterbury Hospital?

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

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

What happens if old sealant might contain asbestos?

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.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

When can you be on site?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

What site paperwork can you supply?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Cost factors for movement joints

To price the job, we consider:

  • Location, for remote and island sites
  • Whether old sealant has to be cut out first
  • Phasing around occupants
  • How much there is to seal

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What we need to price the job

However big the job, the same details help:

  • The site address and postcode
  • Any specification or named product
  • What the building is and how it’s used
  • Asbestos survey details if the building is older

To get a fixed quote, give us a call on 01277 525 020 or email the details over with the site address and an outline of the work. Our quote form is another easy route.

Slabs, ramps and loading bays in Harbledown

The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint. Harbledown is about 52 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.

Warehouse floors on estates like Wincheap Industrial Estate, 0.8 miles to the south-east of Harbledown, carry pallet trucks and forklifts over every saw-cut joint. For a centre such as Whitefriars Shopping Centre (1.1 miles east of Harbledown), the service yard and car park joints usually need attention first.

Harbledown is about 1 mile west of Canterbury, in Kent. We cover Harbledown and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. Across Kent, 931 places are covered, Harbledown among them. London is covered too, around 52 miles from Harbledown.

Why it’s worth doing now in Harbledown

A failed joint seal doesn’t mean the slab, panel or wall needs replacing. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we’ll tell you they need repairing first. Around Harbledown, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
