Slabs, ramps and loading bays in Somerley

Somerley is within about 2 miles of the coast. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so it pays to keep them sealed. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint.

For a school such as Birdham CE Primary School, playground and building joints can be done in the holidays. Office parks like Enborne Business Park (to the south-east of Somerley) have decks, ramps and clad elevations whose joints take movement every day.

Somerley is about 4 miles north-west of Selsey, in West Sussex. Somerley sits inside our coverage and the rest of West Sussex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across West Sussex, 373 places are covered, Somerley among them. For work in that direction, see our Portsmouth page, about 10 miles away.

Commercial sites across PO20 are covered for floor joints. If your site is on Bell Lane and Hundredsteddle Lane or close by, we can quote for floor joints. If your building is just outside Somerley, we cover Almodington (1 mile south-east), Birdham (1 mile north-east), Shipton Green (1 mile north-west), Earnley (1 mile south) and East Wittering (2 miles south-west).

Floor joint sealing for commercial buildings in Somerley

We have been sealing commercial joints since 2005. Applicators carry CSCS cards and work to your site rules, and the business is CHAS accredited and a Constructionline member, with public liability insurance in place. Completed joints come with a 12-month guarantee on our workmanship. We work on loading bays, construction joints and retail and showroom floors, and the usual reasons a site gets in touch are chipped and spalling edges along forklift routes and dock area joints that have failed first. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Somerley, preparation and product choice get the time they need.

Halls, schools and small commercial buildings near places like Somerley have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a day for smaller units, with bigger warehouse floors programmed over several visits, and our waste is bagged and taken away as we go. Rural sites near Somerley may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We look at joint widths, edge condition and the traffic on each route.
  2. The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. The area is handed back once it has cured enough to take traffic.

Preparing the site

  • Have the specification and drawings to hand
  • Send your site hours and access windows
  • Explain the parking and delivery arrangements

Common questions from Somerley clients

Is Somerley off your patch?

Not at all. Somerley is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Does the sea air around Somerley change the choice of sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.

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.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How soon can traffic go back on the floor?

The wait is set by the product’s cure time, and cold floors slow it down. Phasing is planned with that in mind.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Do you seal on top of existing sealant?

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

General trades versus a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Why act early in Somerley

An open joint is a modest filling job while its edges are sound. Wait until the edges have spalled and the concrete needs repairing before the joint can be filled, with longer closures to match. For buildings around smaller places like Somerley, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why us?

  • One number for every site we cover
  • Health and safety: CHAS accredited
  • Clear, fixed quotes
  • Public liability insurance in place

Surface by surface

Isolation joints at walls and columns

Isolation joints separate the slab from walls, columns and plinths so it can move independently. A flexible product suits them better than a stiff filler.

Forklift and pallet-truck routes

Joints on busy routes need a fill that sits flush and resists impact. We match the product to the wheel types and the traffic.

Commercial clients in Somerley

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Somerley. One quote can cover more than one site, which keeps the paperwork simple.

Common problems we fix in Somerley

Left open, joints fill with grit, wrap and wood fragments. Packed debris acts like a wedge every time a wheel crosses so the arrises break sooner.

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

  • Loading bay joints breaking down
  • Open saw cuts full of debris
  • Joint fill separating from the concrete
  • Joint edges breaking up under truck wheels

Hospitals like St Richard's Hospital, 5.2 miles to the north-east of Somerley, have multi-storey or surface car parks whose joints carry vehicles round the clock.
