About our expansion joint sealing in Wexham Street

Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap. We reseal deck and ramp joints with a trafficable sealant chosen for the movement. We work on car park decks and ramps, precast concrete panel joints and brickwork movement joints, and the failures we’re asked to look at most are chipped joint edges on forklift routes and weathered movement joint sealant that no longer flexes. One point of contact handles commercial sealant work in Wexham Street from the first photos to the final walk-round, whether it’s one building or several.

Around smaller places such as Wexham Street, 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.

A 12-month guarantee applies to all our work in Buckinghamshire. Should something we installed fail, call 01277 525 020 or use the quote form and we will come back to it.

How a job runs

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Rural sites near Wexham Street may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Getting the site ready

  • Send any specification or drawings in advance
  • Let us know about inductions and permits
  • Point out any areas we must not close

Floors, slabs and movement joints in Wexham Street

Wexham Street is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.

When to call us in Wexham Street

On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant, while grit and salts work into any gap. A sealant that isn’t trafficable won’t last there.

If one of these sounds familiar, it’s time for a closer look:

  • Car park joints leaking onto vehicles below
  • Joints packed with grit and debris
  • Chipped joint edges on forklift routes
  • Joints where the bead has lost adhesion

Parks like The Business Village (to the south of Wexham Street) combine paved areas, car parks and building elevations, each with joints that move.

How to choose a sealant contractor

Surface by surface

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.

Joints between different materials

Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces priming where the maker calls for it.

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Keep racking legs and heavy point loads off floor joints
  • Treat a small split as a warning, not a cosmetic issue
  • Clear dirt from joint lines during routine cleaning
  • Include every elevation and deck joint in periodic inspections

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. Regular sweeping keeps joint lines clear.

An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load, turning a sealant job into a repair job. A sound seal keeps the joint working.

Site staff or a sealant specialist?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

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.
