Expansion joint sealing in Cranbrook Common

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; water dripping through to the deck below is often the first sign. We reseal deck and ramp joints with a trafficable sealant chosen for the movement, phasing bays so the car park can stay in use. Most enquiries involve spalled or broken joint edges in floors and decks and expansion joints filled with dirt and stones, across precast concrete panel joints, cladding panel joints and brickwork movement joints. For commercial sealant work in Cranbrook Common, you deal with one contact from quote to sign-off, whether it’s one building or several.

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

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

When something else is needed

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Movement on a scale no sealant is meant to absorb
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Joints too narrow for the movement, which need redesigning by the engineer

If in doubt, speak to us on 01277 525 020 or send photos by email and we’ll say what we think before you book.

Surfaces we seal

  • Blockwork control joints
  • Cladding panel joints
  • Brickwork movement joints
  • Podiums and floor movement joints
  • Car park decks and ramps
  • Precast concrete panel joints

Diagnose, treat, sign off

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. For work around Cranbrook Common, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability 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.

What we need from you

  • Let building users know which areas are affected
  • Send your site hours and access windows
  • Make sure the joints can be reached

What the job involves on each surface

Brickwork and blockwork joints

A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing and flag any joint that seems undersized.

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement flagging broken arrises before sealing.

For managing agents and facilities managers

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Cranbrook Common can sit alongside others in a wider programme.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Doing it in-house

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.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

Questions about Cranbrook Common

Can you take on a job at a hospital such as Benenden Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Does a site in Cranbrook Common have to shut while its joints are sealed?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we will plan from there.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Which product is best for expansion joints?

We choose a sealant with a movement capability that suits the joint, classified under BS EN ISO 11600. Where two different materials meet, a hybrid sealant can be the better choice.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also speak to us on 01277 525 020 or email the details over. Include photographs or drawings if you have them.

What guarantee do you give on joint sealing?

It’s backed by our 12-month guarantee. Tell us straight away if a joint we sealed gives trouble in that time.

What happens if it’s left?

Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open without shutting the whole car park. We agree phasing with you before work starts. Halls, stores and units around places like Cranbrook Common may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

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

Why appoint us

  • Colours confirmed for the specified product
  • Matching to RAL references, product permitting
  • One contact handling all your sites
