Expansion joint sealing in Arpinge, done properly

Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. Site teams most often ask us about hardened, cracked sealant on exposed facades and chipped joint edges on forklift routes, on blockwork control joints, podiums and floor movement joints and car park decks and ramps. Most enquiries from Arpinge start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

In and around smaller places like Arpinge, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Slabs, ramps and loading bays in Arpinge

Arpinge is within about 2 miles of the coast. Open joints in coastal car parks and yards let in salt-laden water as well as grit, and edges left open tend to break up faster. Arpinge 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.

Across sites such as Shearway Business Park, which lies south-east of Arpinge, floor and movement joints can be sealed in phases so units keep working. For a school such as Harcourt Primary School, playground and building joints can be done in the holidays. Office parks like Concept Court Business Park (1.2 miles south-east of Arpinge) have decks, ramps and clad elevations whose joints take movement every day.

Arpinge is about 1 mile south-west of Hawkinge, in Kent. Any commercial site in Arpinge is covered, whether it’s a single job or part of a planned programme. 931 places across Kent fall within our area, Arpinge among them. Sites around Brighton have their own page, roughly 58 miles from Arpinge.

Postcode districts covered here: CT18 for movement joints. Just outside Arpinge, we also work in Hawkinge (1 mile north-east), Densole (2 miles north-east), Old Hawkinge (2 miles east), Swingfield Minnis (3 miles north-east) and Elham (3 miles north). Further afield, our area takes in Ashford (12 miles west), Canterbury (12 miles north), Dover (8 miles east), Deal (14 miles north-east), Hythe (3 miles south-west) and Tower Hamlets (7 miles east).

Landmarks near Arpinge

We work on buildings around The Cat & Custard Pot pub. The nearest railway station is Folkestone West station, roughly 1.7 miles south-east of the centre. Other landmarks nearby include Royal Victoria Hospital (2.2 miles south-east) and Folkestone Castle (1.4 miles south-east). For a walk, there’s Cheriton Hill.

How a job runs

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. If others near Arpinge need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We look at the joints, their width and how they’ve failed.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Preparing the site

  • Send any specification or drawings in advance
  • Tell us your opening times and when work is allowed
  • Warn occupants and staff about the work

Request a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Advice

After the work

To get the most from the new sealant:

  • Keep scrapers and ploughs from dragging across joint sealant
  • Keep product details with the building records for the next reseal
  • Inspect exposed joints once the cold weather has passed
  • Treat a small split as a warning, not a cosmetic issue

Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears, especially on car park decks and warehouse floors. A routine sweep is the simplest protection.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint, well after the seal first opened. Resealing promptly prevents internal damage.

Leave it or put it right?

Patching the worst lengths of a joint can make sense short term. The remaining sealant is often close to failing too, and a second visit means paying for access again. We can price a patch and a full reseal side by side. Around Arpinge, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Why appoint us

  • Fully insured, including public liability cover
  • Work carried out by CSCS-carded applicators
  • Clear, fixed quotes
  • Old sealant cut out, never sealed over

Owners, agents and contractors

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Arpinge can form part of a wider programme.

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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.

Cost factors for movement joints

We price every job individually. The main factors are:

  • Removal of failed or old sealant
  • The size and state of each joint
  • Which sealant the job calls for
  • Induction, permit and paperwork requirements

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Sending details for a quote

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

  • Any specification or named product
  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building
  • Whether an asbestos survey exists

To get a fixed quote, give us a call on 01277 525 020 or email us. You can also send details through our quote form.

Arpinge: questions and answers

Is Arpinge too small for you to travel to?

Not at all. Arpinge is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Does a coastal location like Arpinge affect which sealant is used?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

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.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can a joint be sealed if the edges are broken?

A bond is only as strong as the material behind it, so we will tell you if the edges need repairing before sealing. Where it’s visible beforehand, we will say so when we quote.

Is colour matching possible?

It depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
