Expansion joint sealing across Rise Park

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

Expansion joint sealing in Rise Park, done properly

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. Most enquiries involve new sealant over old, now failing and arrises breaking up along floor joints, across precast concrete panel joints, blockwork control joints and cladding panel joints. A single leaking joint is often how a building in Rise Park first comes to us: we look at the rest while we are there and tell you what we find.

London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In Rise Park, as everywhere in London, access, loading and the ULEZ all come into the plan.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

How the job changes by surface

Brickwork and blockwork joints

A brick movement joint full of old mortar or debris can’t close. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.

Concrete and precast panel joints

Precast and concrete panel joints move daily. The sealant needs the right movement capability and a controlled depth.

Do you need expansion joint sealing in Rise Park?

Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, normally means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again unless width and product are reviewed.

It’s worth sending us details if you spot any of the following:

  • Layers of sealant in a movement joint
  • Damp inside where a wall movement joint has failed
  • Car park joints leaking onto vehicles below
  • Hardened, cracked sealant on exposed facades

Schools like Rise Park Infant School often have long brick elevations with movement joints that age quietly.

Comparing quotes

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Who will actually carry out the work
  • Is the sealant right for the movement and the substrate?
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

Our process

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Send asbestos survey details if the building is pre-2000
  • Point out any areas we must not close

Related advice

Should maintenance staff do it?

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

FAQs: Rise Park

Can you work in a London building with booked loading and goods-lift slots?

Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough

Does your area include sites such as Rom Valley Retail Park, near Rise Park?

Yes. Estates, retail parks and business parks around Rise Park, Rom Valley Retail Park among them, are all within reach. To start, just call the office on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

How long will the joint resealing take?

The metres of joint, the access and the amount of removal decide it. Typically it takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints.

Do you cover Rise Park?

Yes. We cover Rise Park and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. For a quote, ring 01277 525 020 or email us.

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Expansion joint sealing around Rise Park: what changes locally

Rise Park has two named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Few London car parks or loading bays can be taken out of use for more than a short spell, so the work is broken into short sections agreed with the building manager.

Another example is Business Centre (2.9 miles south-west of Rise Park), where floors and yards would be done in stages around the occupiers. At a retail site such as Rom Valley Retail Park, which lies south of Rise Park, joints in car parks, service yards and sales floors carry cars, cages and trolleys every day.

Rise Park is about 1 mile north of Romford, in Greater London. Commercial clients in Rise Park use us for work on movement joints, as part of our coverage of Greater London.

What affects the price in Rise Park

Your fixed quote is built from the real scope. It allows for:

  • Distance, for remote addresses

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

What we need to price the job

A few photos plus some basic facts will normally do. Please tell us:

  • Any dates the work must fit around
  • What the building is and how it’s used
  • Any specification or named product
  • Anything awkward about access or site hours

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or email a schedule or drawings to discuss it first.

Keeping the joints sound

To get the most from the new sealant:

  • Act on the first tear or lifting edge rather than waiting
  • Reopen bays and walkways only after the stated cure time
  • Keep scrapers and ploughs from dragging across joint sealant
  • Clear dirt from joint lines during routine cleaning

Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. A routine sweep is the simplest protection.

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.
