Expansion joint sealing for Castle Green sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Honest limits

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Cracking or settlement that calls for an engineer’s assessment
  • Leaks coming from the membrane rather than the joint seal
  • A joint that has to be widened or re-detailed before it can work

If in doubt, call 01277 525 020 or send photos by email and we will say what we think.

Surfaces we seal

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

Expansion joint sealing in Castle Green, done properly

Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side. We reseal deck and ramp joints with a trafficable sealant chosen for the movement, phasing bays so the car park can stay in use. If you have hardened, cracked sealant on exposed facades and expansion joints filled with dirt and stones, we can help. Most enquiries from Castle Green 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.

Around smaller places such as Castle Green, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

When to call us in Castle Green

Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, typically means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again.

Clients typically get in touch after noticing one or more of the following:

  • Debris jammed in movement joints
  • Previous reseals laid over old sealant
  • Car park joints leaking onto vehicles below
  • Damp inside where a wall movement joint has failed

For a school such as St Lawrence CofE (Aided) Primary School, playground and building joints can be done in the holidays.

Questions to ask before you book

  • How joint depth will be controlled
  • How the joint faces will be prepared and primed
  • How they handle RAMS and site documents
  • How the existing material will be dealt with

Our contractor checklist

Floors, slabs and movement joints in Castle Green

Rainfall across the South East, Castle Green included, is lower than in many parts of the UK. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints. Two named trading, business or retail sites lie within about 3 miles of Castle Green. Their warehouses, yards and car parks are exactly where joints take the most punishment.

For an occupier at a site such as Goldsworth Park Trading Estate, 1.4 miles to the south-east of Castle Green, the joints at loading doors and dock levellers normally see the hardest wear. Across sites such as Chobham Business Centre, 2.3 miles to the north-east of Castle Green, floor and movement joints can be sealed in phases so units keep working.

For managing agents and facilities managers

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Castle Green can form part of a wider programme.

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

How a job runs

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. If others near Castle Green need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability.
  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. Each area is handed back after its cure time, under our 12-month guarantee.

What we need from you

  • Agree which areas must stay open
  • Explain the parking and delivery arrangements
  • For older buildings, check the asbestos register before work

How the job changes by surface

Brickwork and blockwork joints

Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing, and tell you if the joint looks too narrow for the movement.

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler.

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
