How we handle expansion joint sealing in Hadlow Down

Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors. We work on car park decks and ramps, precast concrete panel joints and cladding panel joints, and the failures we are asked to look at most are car park joints leaking onto vehicles below and previous reseals laid over old sealant. Most enquiries from Hadlow Down 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.

For a site near Hadlow Down, measurements and photographs up front mean one trip where possible. Note joint widths and the traffic that uses them, and we will take it from there.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When to call us in Hadlow Down

The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it so edge repair has to come before resealing.

Clients usually get in touch after noticing something like this:

  • New sealant over old, now failing
  • Expansion joints filled with dirt and stones
  • Hardened, cracked sealant on exposed facades
  • Car park joints leaking onto vehicles below

For a school such as St Mark's Church of England Primary School, playground and building joints can be done in the holidays.

How to choose a sealant contractor

Hadlow Down: questions and answers

Will you take on work at estates like Tylers Business Park, close to Hadlow Down?

Yes. We cover Hadlow Down and the area around it, including industrial estates, business parks and retail parks such as Tylers Business Park. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Can you work on a hospital site such as Crowborough War Memorial Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How soon can the area be used again?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

What timescale should we allow for resealing expansion joints?

Allow a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Timings are set out in the quote along with the phasing plan.

Can the building stay open while you work?

Typically, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Why act early in Hadlow Down

Patching the worst lengths of a joint can make sense short term. The remaining sealant is often close to failing too and repeated access costs add up. Where it helps, we quote both options. For buildings around smaller places like Hadlow Down, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

A quote for movement joints depends on how many there are, their condition and the access. Call for a quote.

Why us?

  • Colours chosen to suit frames, cladding or finishes where possible
  • 12-month guarantee on workmanship
  • One number for every site we cover
  • Colour agreed before work starts

Traffic, movement and joints around Hadlow Down

Rainfall across the South East, Hadlow Down included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open. At about 37 miles from central London, Hadlow Down is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day.

On a site such as Tylers Business Park (2.4 miles south of Hadlow Down), the movement joints are in car park slabs, paving and building elevations. Large sites such as Crowborough War Memorial Hospital (to the north of Hadlow Down) have car parks, service roads and long elevations with movement joints in brick and panels.

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Changing the joint layout or spacing of a structure
  • Crumbling edges that would give a new bead nothing sound to grip
  • Proprietary pre-formed expansion joint systems

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

Where we work in Hadlow Down

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

Should maintenance staff do it?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Diagnose, treat, sign off

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. If others near Hadlow Down need work, visits can be combined. You will have a fixed quote before work starts.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Each joint is inspected and handed over with our 12-month guarantee.
