How we handle expansion joint sealing in Great Baddow

Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. Site teams most often ask us about expansion joints filled with dirt and stones and car park joints leaking onto vehicles below, on car park decks and ramps, blockwork control joints and cladding panel joints. Most enquiries from Great Baddow start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Rural business units around smaller places such as Great Baddow often have new slabs laid inside older buildings. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Our process

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you. For a site in Great Baddow, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.

  1. We look at the joints, their width and how they’ve failed.
  2. You get a fixed quote with the product and its movement capability stated.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions

Doing it in-house

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Great Baddow: questions and answers

Is a smaller place like Great Baddow outside your area?

No. Places such as Great Baddow are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Is Beehive Business Centre, near Great Baddow, within your area?

Yes, sites like Beehive Business Centre are within our area, along with the rest of Great Baddow. To start, just speak to us on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

What guarantee do you give on joint sealing?

It’s backed by our 12-month guarantee. If a joint we sealed fails inside the 12 months, let us know.

When it isn’t the sealant

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Waterproofing layers buried beneath the sealant
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Broken or spalled joint edges, which need repairing before any sealant goes in

If you’re not sure, just give us a call on 01277 525 020 or send photos by email and we will give you a straight answer.

Joints and surfaces we work on

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

Surface by surface

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it.

Brickwork and blockwork joints

Mortar snots and debris in the joint stop it working. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.

Traffic, movement and joints around Great Baddow

Less than 3 miles from Great Baddow there are at least three named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. Great Baddow sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.

Across sites such as Chelmer Village Retail Park, 1.2 miles to the north of Great Baddow, floor and movement joints can be sealed in phases so units keep working. Schools like Baddow Hall Infant School often have long brick elevations with movement joints that age quietly.

Do you need expansion joint sealing in Great Baddow?

Car park decks and floors face loads that walls never see. Tyres and wheels press on the edges and the sealant. A sealant that isn’t trafficable won’t last there.

If one of these sounds familiar, it’s time for a closer look:

  • Previous reseals laid over old sealant
  • Water dripping through deck or ramp joints
  • Expansion joints filled with dirt and stones
  • Expansion joints split through the centre of the bead

A healthcare site such as Phoenix Hospital, 0.6 miles south of Great Baddow, depends on car parks, ramps and service yards whose joints take traffic all day.

Choosing a commercial sealant contractor

Looking after the joints

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Inspect exposed joints once the cold weather has passed
  • Keep scrapers and ploughs from dragging across joint sealant
  • Treat a small split as a warning, not a cosmetic issue
  • Avoid parking heavy plant or pallets on joint lines

In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.

Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.
