Expansion joint sealing for Southborough sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Southborough can sit alongside others in a wider programme.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

How we handle expansion joint sealing in Southborough

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; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in and the work can be phased so parts of the car park stay open. If you’re dealing with arrises breaking up along floor joints and expansion joints filled with dirt and stones, we can help, on precast concrete panel joints, brickwork movement joints and podiums and floor movement joints alike. A specialist sealant contractor works differently from a general builder: on jobs in Southborough, preparation and product choice get the time they need.

In a smaller place such as Southborough, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Their slabs and walls still need movement joints that work.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What happens if it’s left?

A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

A quote for movement joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Why us?

  • Work carried out by CSCS-carded applicators
  • Constructionline member for supplier checks

Diagnose, treat, sign off

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. Work in places the size of Southborough is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  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

  • Confirm the product named in the specification
  • Warn occupants and staff about the work
  • Move anything stored against the joints

Advice

When it isn’t the sealant

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

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Broken or spalled joint edges, which need repairing before any sealant goes in

If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Include every elevation and deck joint in periodic inspections
  • Clear dirt from joint lines during routine cleaning
  • Brief car park operatives to protect joint lines during winter clearance
  • Reopen bays and walkways only after the stated cure time

Floor joints on main traffic routes need watching more closely than the rest. Keep racking feet and heavy point loads off joint lines, and report any chipped edges early.

A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it, which is bad news for the concrete and the people parking below. Sealing the joint promptly stops it at source.

Your questions answered

Is a hospital such as Tonbridge Cottage Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Will you take on work at estates like Stag Trade Park, close to Southborough?

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

How long will the joint resealing take?

Allow a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Timings are set out in the quote, including any phasing.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Can you seal car park deck joints?

Yes. These joints take wheels, salt and water, so product choice matters.

Warehouse floors and decks around Southborough

Southborough is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints. Less than 3 miles from Southborough there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Hospitals like Tonbridge Cottage Hospital (1.8 miles north-east of Southborough) have multi-storey or surface car parks whose joints carry vehicles round the clock. University campuses such as Canterbury Christ Church University - Salomons, 0.7 miles to the south-west of Southborough, have car parks, paved walkways and building elevations with movement joints.

When to call us in Southborough

Sealant peeling cleanly off one side is an adhesion failure. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes, and it’s common on joints sealed in a hurry.

What tends to prompt an enquiry:

  • Hardened, cracked sealant on exposed facades
  • Previous reseals laid over old sealant
  • Expansion joints split through the centre of the bead
  • Expansion joints filled with dirt and stones

Phasing is what makes joint work possible on busy sites such as Royal Victoria Shopping Centre (1.5 miles south of Southborough): one bay, aisle or car park row at a time.

What to look for in a quote

  • Whether old or failed sealant will be cut out, not overlaid
  • What the guarantee covers, and for how long
  • Proof of insurance
  • Whether primer will be used where the manufacturer specifies it
