Expansion joint sealing near Upper Pond Street

How we handle expansion joint sealing in Upper Pond Street

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in. We work on cladding panel joints, blockwork control joints and podiums and floor movement joints, and what we’re called in for most is damp inside where a wall movement joint has failed and previous reseals laid over old sealant. Most enquiries from Upper Pond Street start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Jobs around smaller places like Upper Pond Street are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Traffic, movement and joints around Upper Pond Street

Upper Pond 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, while winter salting gets into any joint left open. Upper Pond Street lies roughly 37 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London.

For floors and slabs around Upper Pond Street, the product is chosen for the traffic and the movement at each joint.

Signs you need expansion joint sealing in Upper Pond Street

Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way, so we check width and movement before quoting.

These are often picked up first by site or facilities staff:

  • Previous reseals laid over old sealant
  • Water getting into the wall through a failed joint
  • Joints packed with grit and debris
  • Brittle, chalky sealant on external joints

A healthcare site such as Saffron Walden Community Hospital (to the east of Upper Pond Street) depends on car parks, ramps and service yards whose joints take traffic all day.

Questions to ask before you book

  • How they’ll work around occupants
  • How they handle RAMS and site documents
  • How the existing material will be dealt with
  • The named product and why it was chosen

Our contractor checklist

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Changing the joint layout or spacing of a structure
  • Proprietary pre-formed expansion joint systems
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

If in doubt, call the office on 01277 525 020 or email drawings and photos and we will say what we think.

What we seal

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

On site: what to expect

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Upper Pond Street can be grouped with others nearby. You will have a fixed quote before work starts.

  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. Old sealant and filler are cut out and the joint faces cleaned back to sound material.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Your questions answered

Do we have to stop operations in Upper Pond Street while the joints are sealed?

Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.

Is a hospital such as Saffron Walden Community Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

How long does movement joint sealing take?

Expect anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Cure time before reopening is confirmed on the day.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Can you fit around our working hours?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

What do you charge?

There isn’t a price list, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.

How the job changes by 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.

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately.

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Leave barriers in place until fresh joint sealant has cured
  • Keep scrapers and ploughs from dragging across joint sealant
  • Keep product details with the building records for the next reseal
  • Include every elevation and deck joint in periodic inspections

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. Keeping the area coned off until then avoids tyre marks and damage.

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.
