Expansion joint sealing across Fawkham Green

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How we handle expansion joint sealing in Fawkham Green

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. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. We work on precast concrete panel joints, brickwork movement joints and blockwork control joints, and the failures we are asked to look at most are sealant peeling off one face of the joint and expansion joints filled with dirt and stones. Looking for mastic applicators who cover Fawkham Green? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Around smaller places such as Fawkham Green, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Slabs, ramps and loading bays in Fawkham Green

The 3 miles around Fawkham Green take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. Fawkham Green 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 winter de-icing salt on car parks and ramps works into any open joint.

For an occupier at a site such as Heaver Farm Trading Estate, 0.7 miles south-east of Fawkham Green, the joints at loading doors and dock levellers normally see the hardest wear. Schools such as New Ash Green Primary School have movement joints in their walls and floors that are easy to overlook. Phasing is what makes joint work possible on busy sites such as Blue Chalet Industrial Park (1.5 miles south-west of Fawkham Green): one bay, aisle or car park row at a time.

Fawkham Green is about 6 miles south-west of Northfleet, in Kent. Anywhere in DA3, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Fawkham Green is one of 931 places we cover in Kent for movement joints. Our London page has more on work in that area, about 19 miles away.

Commercial sites across DA3 are covered. If your site is on Fawkham Green Road, Brands Hatch Road and Valley Road or close by, send details and we will quote for movement joints. We also cover Speed Gate (1 mile north-west), West Yoke (1 mile east), Ash (1 mile south-east), West Kingsdown (2 miles south-west) and Maplescombe (2 miles west). Bigger towns within reach include Maidstone (13 miles south-east), Dartford (6 miles north-west), Sevenoaks (7 miles south-west), Gravesend (6 miles north-east), Tonbridge (12 miles south) and Northfleet (6 miles north-east).

Leave it or put it right?

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. Halls, stores and units around places like Fawkham Green may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

A quote for movement joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

For managing agents and facilities managers

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.

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.

What sets the cost

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Which sealant the job calls for
  • Quantities, in metres or numbers
  • Phasing around occupants
  • Distance, for remote addresses

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Before you send an enquiry

Whether it’s one area or a whole building, these details speed things up:

  • The site address and postcode
  • What the building is and how it’s used
  • Your programme or deadline
  • Photos of the joints, close up and from further back

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. For a chat about it beforehand, ring 01277 525 020 or email the details over.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Leaks coming from the membrane rather than the joint seal
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

On site: what to expect

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Jobs in and around smaller places like Fawkham Green are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  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. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Preparing the site

  • Explain the parking and delivery arrangements
  • Tell us which areas need to stay in use
  • Tell us what induction or permit system the site runs

Your questions answered

Will you take on work at estates like Heaver Farm Trading Estate, close to Fawkham Green?

Yes. Estates, retail parks and business parks around Fawkham Green, Heaver Farm Trading Estate among them, are all within reach. Photos and a short description are enough for a first look.

Would you work within a site like Darent Valley Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Why has the sealant in our expansion joints split?

Most often the movement is too much for the product or the joint width. That’s why we check width, depth and movement class before quoting so the same failure isn’t repeated.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

What guarantee do you give on joint sealing?

The workmanship is guaranteed for 12 months from sign-off. Regular sweeping and inspection help the joints last.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

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.

Maintenance after handover

Once the work is signed off, these steps help:

  • Include every elevation and deck joint in periodic inspections
  • Clear dirt from joint lines during routine cleaning
  • Inspect exposed joints once the cold weather has passed
  • Avoid parking heavy plant or pallets on joint lines

Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint. Keeping the area coned off until then avoids tyre marks and damage.

An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load. Keeping the seal sound avoids all of that.
