About our expansion joint sealing in Charney Bassett

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. The enquiries we see most involve joints packed with grit and debris and rain penetration at brick or block movement joints, across podiums and floor movement joints, precast concrete panel joints and brickwork movement joints. Most enquiries from Charney Bassett start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In and around smaller places like Charney Bassett, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When to call us in Charney Bassett

Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens, which is why depth control matters.

Most enquiries start with one or more of the following:

  • Previous reseals laid over old sealant
  • Chipped joint edges on forklift routes
  • Hardened, cracked sealant on exposed facades
  • Leaks through car park deck joints onto the level below

A campus such as University of Oxford, 3.5 miles north of Charney Bassett, has long runs of movement joint in its buildings, decks and paving.

Questions to ask before you appoint anyone

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. Where it helps, we quote both options. One visit to deal with every failing joint makes more sense than several trips to a place like Charney Bassett, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

  • Colours confirmed for the specified product
  • Fully insured, including public liability cover

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Questions about Charney Bassett

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

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Is a smaller place like Charney Bassett outside your area?

No. Places such as Charney Bassett are covered as much as the big towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Can the building stay open while you work?

In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Can you seal car park deck joints?

Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement.

Why do our movement joints keep failing?

Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. We diagnose which one it is before resealing since each needs a different fix.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

How a job runs

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 each bead is tooled to a neat concave finish. Jobs in and around smaller places like Charney Bassett are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  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, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

What we need from you

  • Tell us what induction or permit system the site runs
  • Move anything stored against the joints
  • Confirm the product named in the specification

Keeping the joints sound

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Inspect exposed joints once the cold weather has passed
  • Put movement joints on the planned maintenance inspection round
  • Brief car park operatives to protect joint lines during winter clearance

Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records so future maintenance isn’t guesswork.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers, and the damage spreads along the joint. Sealing early protects the edges.

Honest limits

Honesty saves time and money. Fresh joints won’t solve:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Cracking or settlement that calls for an engineer’s assessment
  • Leaks coming from the membrane rather than the joint seal

Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Surfaces we seal

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