Expansion joint sealing in Swallows Cross

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement. We work on cladding panel joints, car park decks and ramps and podiums and floor movement joints, and what we’re called in for most is arrises breaking up along floor joints and sealant peeling off one face of the joint. For commercial sealant work in Swallows Cross, you deal with one contact from quote to sign-off, whether it’s one building or several.

Around smaller places such as Swallows Cross, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Slabs, ramps and loading bays in Swallows Cross

The South East is one of the drier parts of the UK. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints. Central London is about 22 miles from Swallows Cross. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day.

Schools such as Shenfield High School have movement joints in their walls and floors that are easy to overlook. Large sites such as Brentwood Community Hospital (2.9 miles south of Swallows Cross) have car parks, service roads and long elevations with movement joints in brick and panels.

Swallows Cross is about 3 miles north-east of Brentwood, in Essex. We cover Swallows Cross and the rest of Essex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Swallows Cross is one of 644 places in Essex on our list. Our London page has more on work in that area.

Why deal with it now?

Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s usually not far behind. We can price a patch and a full reseal side by side. Around Swallows Cross, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

Why clients in Swallows Cross choose us

  • Colour options checked against the specified product
  • Joints cleaned back to sound surfaces
  • RAL and finish matching where the product range allows
  • Fixed quotes based on photographs, drawings or a visit

Different surfaces, different methods

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in, phased so parts of the car park stay open.

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Close-up photographs help us judge the joints or a site visit fills the gaps.

Looking after the joints

After handover, these steps help:

  • Raise snow-clearing blades over deck joints where possible
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Keep product details with the building records for the next reseal
  • Treat a small split as a warning, not a cosmetic issue

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal and a look at the joints after winter catches any damage.

On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. That water often carries de-icing salts with it, which is bad news for the concrete and the people parking below. Resealing early limits the damage.

From enquiry to sign-off

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. If others near Swallows Cross need work, visits can be combined. A fixed quote is given before anything starts.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. The failed seal is removed and both faces are cleaned until sound and dry.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

  • Confirm the product named in the specification
  • Let us know about inductions and permits
  • Point out any areas we must not close

Advice

What sealant work can’t fix

Honesty saves time and money. Fresh joints won’t solve:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Crumbling edges that would give a new bead nothing sound to grip
  • A joint that has to be widened or re-detailed before it can work

Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

What we seal

  • Precast concrete panel joints
  • Blockwork control joints
  • Brickwork movement joints
  • Podiums and floor movement joints
  • Cladding panel joints
  • Car park decks and ramps

Site staff or a sealant specialist?

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Swallows Cross: questions and answers

Is a hospital such as Brentwood Community Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Will our site in Swallows Cross have to close for joint sealing?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Will you come and look before quoting?

It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.

Do you use silicone or polyurethane in movement joints?

We choose a sealant with a movement capability that suits the joint as set out in BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.

Can you send site paperwork?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
