Expansion joint sealing for commercial buildings in Worthing

Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. We work on precast concrete panel joints, car park decks and ramps and podiums and floor movement joints, and the failures we are asked to look at most are water getting into the wall through a failed joint and layers of sealant in a movement joint. Facilities teams, main contractors and managing agents in Worthing tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Work on floor and movement joints in a large place such as Worthing is typically phased: aisle by aisle or deck by deck, with areas handed back as each section cures.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common problems we fix in Worthing

On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant. A sealant that isn’t trafficable won’t last there.

Look out for the following:

  • Water getting into the wall through a failed joint
  • Layers of sealant in a movement joint
  • Weathered movement joint sealant that no longer flexes
  • Expansion joints split through the centre of the bead

For buildings at a park such as Goring Business Park, which lies south-west of Worthing, brick and panel movement joints are easy to forget until one leaks.

What your quote should include

  • Their plan for phasing and protecting the area
  • Will failed sealant be removed rather than covered?
  • Proof of insurance
  • Will RAMS and insurance details be available?

How to choose a sealant contractor

Why deal with it now?

Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now. Urgent joints now, the rest later, is often the sensible plan. If one joint has failed on your building in Worthing, others of the same age may be close behind. Dealing with them together saves repeat visits.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why appoint us

  • Health and safety: CHAS accredited
  • A fixed quote before work starts
  • Colours confirmed for the specified product
  • Workmanship guaranteed for 12 months

See our cost guide and our accreditations.

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

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.

Our process

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For premises in central Worthing, deliveries and parking need a bit of planning, whereas edge-of-town units normally have yard space. Let us know what’s there when you send details.

  1. First the joints are inspected, widths measured and the type of failure noted.
  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. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Preparing the site

  • Agree which areas must stay open
  • Have the specification and drawings to hand
  • Make sure the joints can be reached

Ask for a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Advice

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Surface by surface

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement, phased so parts of the car park stay open.

Podium joints

Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.

Common questions from Worthing clients

Does your area include sites such as Goring Business Park, near Worthing?

Yes, sites like Goring Business Park are within our area, along with the rest of Worthing. Send details of the unit and the work through our quote form for a quick quote.

Would you work within a site like Worthing Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Why has the sealant in our expansion joints split?

The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. Working out the cause comes first.

Which product is best for expansion joints?

It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks usually need a polyurethane unless the specification names something else.

Can you seal car park deck joints?

Yes. These joints take wheels, salt and water, so product choice matters, and we’ll tell you if any edges need repairing first.

Do you cover Worthing?

Yes. Worthing is in our area and the rest of West Sussex. For a quote, give us a call on 01277 525 020 or use the quote form.

Do you offer coloured sealant?

That depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

Slabs, ramps and loading bays in Worthing

The sea is no more than about 2 miles from Worthing. Open joints in coastal car parks and yards let in salt-laden water as well as grit, which is why split joints are worth sealing before the edges deteriorate. Worthing has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Sites like Worthing Hospital, 1.6 miles east of Worthing, carry ambulances, deliveries and visitors’ cars over their road and deck joints. At places like Downlands Business Park (1.8 miles north-east of Worthing), joints are sealed a section at a time so operations carry on.
