Looking after the joints

A few simple habits keep the new joints working:

  • Keep scrapers and ploughs from dragging across joint sealant
  • Avoid parking heavy plant or pallets on joint lines
  • Leave barriers in place until fresh joint sealant has cured
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints

Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in. Should you spot a problem, you can give us a call on 01277 525 020 or email a schedule or drawings and send a picture.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.

How we handle expansion joint sealing in Broadgate

A movement joint only works while its seal does. Once it fails, water, grit and debris get in, the joint can’t close properly and its edges begin to crumble. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on car park decks and ramps, brickwork movement joints and podiums and floor movement joints, and what we’re called in for most is movement joints with split or torn sealant and new sealant over old, now failing. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Broadgate, preparation and product choice get the time they need.

In and around smaller places like Broadgate, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

How the job changes by surface

Car park decks and ramps

Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again, and we will tell you if any edges need repairing first.

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler.

Questions about Broadgate

Would you work within a site like Wessex Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Does your area include sites such as Sleepy Hollow Business Park, near Broadgate?

Yes. Our area takes in Broadgate and its surroundings, with estates and business parks such as Sleepy Hollow Business Park included. Photos and a short description are enough for a first look.

Is movement joint sealing guaranteed?

The 12-month guarantee applies to the workmanship. If a joint we sealed fails inside the 12 months, let us know.

What happens if it rains on the day?

The joint has to be dry, and the air and surface temperature inside the product’s limits. Frost, rain and condensation on steel or concrete can hold up external work so external dates keep some flexibility.

Can you seal car park deck joints?

Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement, and phased work can be planned so parts of the car park stay in use.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Leave it or put it right?

Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Older rural buildings around Broadgate move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you are ready.

When it isn’t the sealant

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Cracking or settlement that calls for an engineer’s assessment
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Joints too narrow for the movement, which need redesigning by the engineer

Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

What we seal

Slabs, ramps and loading bays in Broadgate

The 3 miles around Broadgate take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.

Hospitals like Wessex Hospital (2.3 miles east of Broadgate) have multi-storey or surface car parks whose joints carry vehicles round the clock. At a retail site such as Chestnut Avenue Retail Park, 2.8 miles south of Broadgate, trolleys, cages and cars run over floor and slab joints all day. Office parks like Sleepy Hollow Business Park (1.2 miles west of Broadgate) have decks, ramps and clad elevations whose joints take movement every day.

For managing agents and facilities managers

When you manage a building on behalf of an owner, 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.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and we clear our waste as we work. If others near Broadgate need work, visits can be combined. A fixed quote is given before anything starts.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  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. Areas reopen once cured, and the work carries our 12-month guarantee.

Getting the site ready

  • Flag any permit to work we will need
  • Make sure the joints can be reached
  • Tell staff and tenants when we’ll be in
