Expansion joint sealing in Prestonville

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Damaged metal nosings or cover plates over a joint
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Changing the joint layout or spacing of a structure

If you’re not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer.

Joints and surfaces we work on

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

Expansion joint sealing in Prestonville

We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. Every one calls for a sealant picked for its movement, exposure and traffic and we name it in the quote. If you have chipped joint edges on forklift routes and previous reseals laid over old sealant, we can put it right, on brickwork movement joints, podiums and floor movement joints and precast concrete panel joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Prestonville it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In a smaller place such as Prestonville, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Concrete floors and yards in these buildings move and crack like any others.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

What the job involves on each surface

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.

Brickwork and blockwork joints

Brick and block edges need careful preparation. We clean them back to sound material and prime where the manufacturer specifies before the bead goes in.

Expansion joint sealing in Prestonville: the local picture

Prestonville sits close to the coast, within about 1 mile. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner. Less than 3 miles from Prestonville there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Schools like Stanford Infant School often have long brick elevations with movement joints that age quietly. Warehouse floors on estates like Centenary Industrial Estate (to the east of Prestonville) carry pallet trucks and forklifts over every saw-cut joint.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. What matters most for a job in Prestonville is a clear list of what needs doing, so send photographs of each area. A fixed quote follows.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

What we need from you

  • Make sure the joints can be reached
  • Explain the parking and delivery arrangements
  • Confirm the product named in the specification

Advice

Building owners, agents and FMs in Prestonville

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

Questions about Prestonville

Does a coastal location like Prestonville affect which sealant is used?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Can you work at a site such as Centenary Industrial Estate, by Prestonville?

Yes. We cover Prestonville and the area around it, including industrial estates, business parks and retail parks such as Centenary Industrial Estate. To start, just phone 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Does the weather affect joint sealing?

Outside work depends on conditions because a damp or frozen joint won’t take a proper bond. Internal floor joints are far less affected.

What sealant do you use in movement joints?

Movement capability matters most. Hybrid or MS polymer products suit some mixed-material joints.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Do the joint edges need to be sound before sealing?

Spalled edges need repairing before a new seal will last, and we’ll point out where that’s the case. Sealing over them leads to early failure.

Maintenance after handover

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

  • Plan racking layouts so feet don’t land on a joint
  • Keep scrapers and ploughs from dragging across joint sealant
  • Treat a small split as a warning, not a cosmetic issue
  • Record the sealant used and the date in the O&M file

Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Sealing early protects the edges.

Common problems we fix in Prestonville

When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons.

Typical triggers for a call:

  • Expansion joints filled with dirt and stones
  • Damp inside where a wall movement joint has failed
  • Hardened, cracked sealant on exposed facades
  • Movement joints with split or torn sealant

Phasing is what makes joint work possible on busy sites such as Goldstone Retail Park (1 mile west of Prestonville): one bay, aisle or car park row at a time.

Questions to ask before you book

  • How they handle RAMS and site documents
  • Their plan for phasing and protecting the area
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Do they follow the manufacturer’s priming guidance?
