Expansion joint sealing for commercial buildings in Gravesend

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. A sealant suited to traffic and the expected movement goes in. We work on blockwork control joints, precast concrete panel joints and podiums and floor movement joints, and the usual reasons a site gets in touch are torn sealant in brick or block movement joints and water dripping through deck or ramp joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Gravesend is the same: the right product in a properly prepared joint.

Joints in town car parks and service yards take tyres, de-icing salt and standing water. Catching a joint before its edges break is the simpler route.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

How a job runs

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Town-centre premises in Gravesend may have limited parking, so tell us what’s nearby. On estates and business parks it’s normally simpler.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  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

  • Tell us what induction or permit system the site runs
  • Share the asbestos register for older buildings
  • Tell us your opening times and when work is allowed

How the job changes by surface

Concrete and precast panel joints

Precast and concrete panel joints move daily. The sealant needs the right movement capability and a controlled depth.

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.

Warehouse floors and decks around Gravesend

Gravesend is within about 2 miles of the coast. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, and edges left open tend to break up faster. Less than 3 miles from Gravesend 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.

Another example is Lion Business Park, which lies north-east of Gravesend, where floors and yards would be done in stages around the occupiers. A healthcare site such as Gravesham Community Hospital, 1.1 miles to the north-west of Gravesend, depends on car parks, ramps and service yards whose joints take traffic all day. Warehouse floors on estates like Canal Industrial Park (to the north of Gravesend) carry pallet trucks and forklifts over every saw-cut joint.

Gravesend is about 9 miles north-west of Gillingham, in Kent. Businesses, contractors and managing agents in Gravesend use us for work on movement joints. Gravesend is one of 931 places we cover in Kent for movement joints. We also cover London, around 21 miles from Gravesend.

Postcode districts covered here: DA12 and DA11. Buildings on Christ Church Road, Hillside Drive and Laurel Avenue are within our area. Gravesend sits on or close to the A2 and A226, useful when we plan access and materials. We also cover Windmill Hill (1 mile north-west), Milton-next-Gravesend (1 mile north-east), Denton (1 mile east), Singlewell or Ifield (1 mile south) and Northfleet (1 mile west) for movement joints. A short drive away, we cover Maidstone (13 miles south-east), Dartford (7 miles west), Sevenoaks (13 miles south-west), Swanley (9 miles west), Kings Hill (11 miles south) and Foley Park (12 miles south-east).

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Honest limits

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Waterproofing layers buried beneath the sealant
  • Changing the joint layout or spacing of a structure
  • Concrete or masonry repairs along the arrises

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 before you book.

Surfaces we seal

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

FAQs: Gravesend

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

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.

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

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do the joint edges need to be sound before sealing?

Spalled edges need repairing before a new seal will last, and we’ll point out where that’s the case. A bead on a broken edge soon lets go.

What causes movement joint sealant to fail?

Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

When can the area be used after sealing?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
