How we handle expansion joint sealing in Froxfield 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. 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 car park joints leaking onto vehicles below and damp inside where a wall movement joint has failed, we can help, on blockwork control joints, precast concrete panel joints and car park decks and ramps alike. A single leaking joint is often how a building in Froxfield Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Jobs around smaller places like Froxfield Green are planned so the whole job is done in one visit. Note joint widths and the traffic that uses them, and we will take it from there.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

How the quote is worked out

We price every job individually. The things that drive the figure:

  • The product specified
  • Whether the work must be split into stages
  • Travel to remote or island sites
  • Removal of failed or old sealant

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

What to include in your enquiry

A good diagnosis starts with the right details. Tell us:

  • When you need the work done
  • The asbestos register, for older buildings
  • Whether the building will be occupied during the work
  • Approximate linear metres or a joint schedule

To get a fixed quote, give us a call on 01277 525 020 or email us with the site address and an outline of the work. You can also send details through our quote form.

For managing agents and facilities managers

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

After the work

To get the most from the new sealant:

  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Note which joints were done, when, and with what
  • Put movement joints on the planned maintenance inspection round
  • Treat a small split as a warning, not a cosmetic issue

Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears, especially on car park decks and warehouse floors. Regular sweeping keeps joint lines clear.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Catching it early keeps the water outside.

Your questions answered

Do you take on work at healthcare sites like Petersfield Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is a smaller place like Froxfield Green outside your area?

Not at all. Froxfield Green is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

What timescale should we allow for resealing expansion joints?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. As a guide, it typically takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing.

What causes movement joint sealant to fail?

Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. We diagnose which one it is before resealing, because the fix differs.

Can you seal car park deck joints?

Yes. Let us know the opening hours and which levels or bays have to stay available and we will plan around them.

Which product is best for expansion joints?

The specification comes first, then the joint’s movement and exposure. The quote states the sealant and its movement class, so you know what’s going in.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and our waste is bagged and taken away as we go. For a building around Froxfield Green, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • Flag any permit to work we’ll need
  • Tell staff and tenants when we will be in
  • Tell us which areas need to stay in use

Quotes

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or send photos by email.

Where floor joints take the most wear near Froxfield Green

Central London is about 51 miles from Froxfield Green. The roads out of London are lined with trade parks and distribution sheds. Froxfield Green 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, while winter salting gets into any joint left open.

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

Froxfield Green is about 3 miles north-west of Petersfield, in Hampshire. Across the GU32 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

When to bring in a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Signs you need expansion joint sealing in Froxfield Green

Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens so backing is set before sealing.

Typical triggers for a call:

  • Rain penetration at brick or block movement joints
  • Leaks through car park deck joints onto the level below
  • Spalled or broken joint edges in floors and decks
  • Expansion joints split through the centre of the bead

Large sites such as Petersfield Hospital, 2.7 miles to the south-east of Froxfield Green, have car parks, service roads and long elevations with movement joints in brick and panels.
