When something else is needed

Being straight saves everyone time. New sealant won’t cure:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Concrete or masonry repairs along the arrises
  • Changing the joint layout or spacing of a structure

If you are not sure, just speak to us on 01277 525 020 or email the details over and we’ll give you a straight answer.

What we seal

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

Doing it in-house

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Joints that move: notes for Shipbourne

Central London is about 24 miles from Shipbourne. The roads out of London are lined with trade parks and distribution sheds. Rainfall across the South East, Shipbourne included, is lower than in many parts of the UK. External joints still wait for dry conditions, while winter salting gets into any joint left open.

For estates staff at a university like University of Kent - Tonbridge, 3.8 miles to the south of Shipbourne, building and paving joints are part of the planned maintenance list. Hospitals like Hollanden Park Hospital, 2.4 miles south-west of Shipbourne, have multi-storey or surface car parks whose joints carry vehicles round the clock. Schools like Shipbourne School often have long brick elevations with movement joints that age quietly.

Shipbourne is about 3 miles north of Tonbridge, in Kent. Businesses, contractors and managing agents in Shipbourne can call on us for movement joints. 931 places across Kent fall within our area, including Shipbourne. There’s a separate page for London, roughly 24 miles from Shipbourne.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Report split or peeling joint sealant early
  • Clear dirt from joint lines during routine cleaning
  • Put movement joints on the planned maintenance inspection round
  • Reopen bays and walkways only after the stated cure time

Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. A routine sweep is the simplest protection.

Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall, turning a sealant job into a repair job. A sound seal keeps the joint working.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Shipbourne may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Tell staff and tenants when we will be in
  • Arrange parking or a loading space
  • Clear stock, furniture or equipment away from the joints

Questions about Shipbourne

Do we have to stop operations in Shipbourne while the joints are sealed?

Typically not: we work in sections and hand each one back once it has cured. We agree the sequence and timings with you before we start.

Is a smaller place like Shipbourne outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

How do we ask for a quote?

You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or use the quote form. Include photographs or drawings if you have them.

What causes movement joint sealant to fail?

Normally the joint is moving more than the sealant can take. We review the joint design as well as the sealant before pricing.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Surface by surface

Brickwork and blockwork joints

Masonry faces are often porous, dusty or crumbly. We clean them back to sound material and prime where the manufacturer specifies, then seal and tool the joint.

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement with bays done in phases so the car park keeps running.

Why act early in Shipbourne

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. Halls, stores and units around places like Shipbourne may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

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.

Why us?

  • Colours confirmed for the specified product
  • Our applicators hold CSCS cards
  • Products installed to the manufacturer’s instructions
  • Workmanship guaranteed for 12 months
