How we handle expansion joint sealing in Dirleton

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels so the product has to suit both the traffic and the movement. If the arrises are already broken, we will say so before sealing. If you have chipped joint edges on forklift routes and joints where the bead has lost adhesion, we can help, on precast concrete panel joints, blockwork control joints and podiums and floor movement joints alike. A single leaking joint is often how a building in Dirleton first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For floor or movement joints around smaller places like Dirleton, we plan to finish in one visit where we can. Send photos, joint widths and details of the traffic first.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Jobs near Dirleton are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  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.

Preparing the site

  • Explain the parking and delivery arrangements
  • Flag any permit to work we’ll need
  • For older buildings, check the asbestos register before work

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Movement on a scale no sealant is meant to absorb
  • Leaks coming from the membrane rather than the joint seal

If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think.

Where we work in Dirleton

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

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Maintenance after handover

Regular inspection catches problems early. Specifically:

  • Plan racking layouts so feet don’t land on a joint
  • Brief car park operatives to protect joint lines during winter clearance
  • Leave barriers in place until fresh joint sealant has cured
  • Inspect exposed joints once the cold weather has passed

Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints, and report any chipped edges early.

Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.

Common problems we fix in Dirleton

Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600.

Things that typically lead to an enquiry:

  • Movement joints with split or torn sealant
  • Damp inside where a wall movement joint has failed
  • Sealant peeling off one face of the joint
  • Debris jammed in movement joints

Schools such as North Berwick High School have movement joints in their walls and floors that are easy to overlook.

Questions to ask before you book

  • How they’ll work around occupants
  • How the existing material will be dealt with
  • Whether their applicators hold CSCS cards
  • What site paperwork they can supply

How to choose a sealant contractor

Different surfaces, different methods

Podium joints

Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal and flag it if the membrane looks like the source.

Brickwork and blockwork joints

Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing.

Warehouse floors and decks around Dirleton

Dirleton lies within about 2 miles of the sea. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, and edges left open tend to break up faster. Dirleton is in the east of Scotland, which is drier than the west. Frost and de-icing salt still find their way into open external joints. Resealing before the cold months helps protect the edges.

Sites like Edington Cottage Hospital, 2.5 miles east of Dirleton, carry ambulances, deliveries and visitors’ cars over their road and deck joints.
