Expansion joint sealing in Cootham, done properly

Brickwork and blockwork walls have vertical movement joints at intervals. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied. If you have debris jammed in movement joints and arrises breaking up along floor joints, we can help, on car park decks and ramps, blockwork control joints and brickwork movement joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Cootham, that means joint design, primers and backing rod as standard.

For a site near Cootham, measurements and photographs up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Different surfaces, different methods

Brickwork and blockwork joints

Long brick and block elevations have movement joints at intervals. They take a low-modulus sealant with a movement class to suit laid over backing rod at the correct depth.

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.

Questions we are asked in Cootham

Do we have to stop operations in Cootham while the joints are sealed?

In most 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.

Is Quell Farm Industrial Estate, near Cootham, within your area?

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

What sealant do you use in movement joints?

We choose a sealant with a movement capability that suits the joint, classified under BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, which many sites require.

What do you charge?

We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.

What site paperwork can you supply?

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

When can you be on site?

We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Maintenance after handover

To get the most from the new sealant:

  • Keep scrapers and ploughs from dragging across joint sealant
  • Include every elevation and deck joint in periodic inspections
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Keep racking legs and heavy point loads off floor joints

In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints.

Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.

When to bring in a specialist

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

A short, simple internal joint is often within reach of a maintenance team. 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.

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Cootham are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Clear stock, furniture or equipment away from the joints
  • Explain the parking and delivery arrangements

Honest limits

Some faults sit outside our scope, and we say so rather than covering them up:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Crumbling edges that would give a new bead nothing sound to grip
  • Cracking or settlement that calls for an engineer’s assessment

Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we will tell you honestly.

Surfaces we seal

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

Warehouse floors and decks around Cootham

Cootham is in the South East, one of the UK’s drier regions. 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. Cootham lies roughly 43 miles out from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day.

In a school such as Storrington Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. At places like Wiston Business Park, 2.9 miles east of Cootham, joints are sealed a section at a time so operations carry on. Estates like Quell Farm Industrial Estate (2.8 miles west of Cootham) combine warehouse slabs, yards and loading bays, all with joints under wheels.

Cootham is about 7 miles north-west of Worthing, in West Sussex. We send applicators to Cootham for movement joints, handled exactly as we handle every other area. Cootham is one of 373 places we cover in West Sussex. There’s a separate page for Brighton, roughly 16 miles from Cootham.

Why it’s worth doing now in Cootham

Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now because damage continues. Urgent joints now, the rest later, is often the sensible plan. Converted and older buildings near places like Cootham tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
