Signs you need expansion joint sealing in South Bank

Sealant peeling cleanly off one side is an adhesion failure. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes and it often shows on rushed work.

Clients typically get in touch after noticing something like this:

  • Sealant peeling off one face of the joint
  • Leaks through car park deck joints onto the level below
  • Chipped joint edges on forklift routes
  • Damp inside where a wall movement joint has failed

Warehouse floors on estates like Grand Vitesse Industrial Estate (0.6 miles east of South Bank) carry pallet trucks and forklifts over every saw-cut joint.

What to look for in a quote

  • Do they follow the manufacturer’s priming guidance?
  • The terms of the workmanship guarantee
  • Will failed sealant be removed rather than covered?
  • Their approach to joint depth and backing

Choosing a commercial sealant contractor

Expansion joint sealing for commercial buildings in South Bank

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. The product depends on the movement, the weather and anything that runs over it. We work on car park decks and ramps, cladding panel joints and podiums and floor movement joints, and the failures we’re asked to look at most are damp inside where a wall movement joint has failed and movement joints with split or torn sealant. A single leaking joint is often how a building in South Bank first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around South Bank, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. When a joint fails, grit and water get in and the arrises start to break up.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Warehouse floors and decks around South Bank

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. The 3 miles around South Bank take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.

At a retail site such as Brunswick Centre (1.4 miles north of South Bank), trolleys, cages and cars run over floor and slab joints all day. Hospital campuses such as St Thomas' Hospital, under half a mile to the south of South Bank, grow in stages, leaving movement joints wherever new blocks meet old.

South Bank is about 1 mile west of London, in Greater London. Our applicators travel to South Bank for work on movement joints. South Bank is one of 764 places in Greater London on our list for movement joints.

Work on movement joints is covered throughout SE1, WC2E and WC2N. If your site is on York Road, Spur Road and Lower Road or close by, we can quote for movement joints. Access to South Bank is via the A301 and A302, so getting applicators and materials to site is simple. Nearby places we also cover include Waterloo (1 mile south-east), Adelphi (1 mile north-west), Charing Cross (1 mile north-west), Temple (1 mile north-east) and Aldwych (1 mile north). Nearby towns on our patch include Kensington (4 miles west), Walthamstow (7 miles north-east), Hampstead (4 miles north-west), Ruislip (14 miles west), Stockwell (3 miles south) and Orpington (13 miles south-east).

South Bank has its own railway station: London Waterloo station. Nearby you’ll also find Florence Nightingale Museum (less than half a mile south) and Royal Waterloo Hospital for Children and Women (less than half a mile north-east).

General trades versus a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Site maintenance staff can often handle a short internal joint. 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.

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Looking after the joints

Regular inspection catches problems early. Specifically:

  • Include every elevation and deck joint in periodic inspections
  • Check joints after long freezing spells
  • Avoid parking heavy plant or pallets on joint lines
  • Leave barriers in place until fresh joint sealant has cured

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal.

On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. That water often carries de-icing salts with it and it can affect the structure over time. Sealing the joint promptly stops it at source.

South Bank: questions and answers

Is a hospital such as St Thomas' Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Grand Vitesse Industrial Estate, near South Bank, within your area?

Yes. We cover South Bank and the area around it, including industrial estates, business parks and retail parks such as Grand Vitesse Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

What happens if it rains on the day?

Sealant needs a dry joint and a temperature within the product’s range. Frost, rain and condensation on steel or concrete can hold up external work.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Can you work on car park ramps and decks?

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.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Cost factors for movement joints

A fixed quote reflects the actual work. It takes account of:

  • The product specified
  • The site’s rules and procedures
  • Joint width, depth and condition
  • Whether old sealant has to be cut out first

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Sending details for a quote

However big the job, these details speed things up:

  • Any dates the work must fit around
  • The postcode of the building
  • Photos of the joints, close up and from further back
  • Asbestos survey details if the building is older

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

How a job runs

Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. In South Bank, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. We look at the joints, their width and how they’ve failed.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Preparing the site

  • Confirm the product named in the specification
  • Point out parking and an unloading spot
  • Send your site hours and access windows
