About our floor joint sealing in Ampfield

Concrete floors in warehouses and factories are cut into bays with saw cuts and day joints, and each joint line is a weak edge that wheels run over all day. We fill or seal them with a product matched to the traffic and the movement, so the arrises are supported and grit stays out. We work on saw-cut induced joints, forklift and pallet-truck routes and loading bays, and the failures we’re asked to look at most are joint fill separating from the concrete and open saw cuts full of debris. Looking for mastic applicators who cover Ampfield? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Halls, schools and small commercial buildings near places like Ampfield have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Your questions answered

Is Ampfield too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Would you work within a site like Romsey Hospital?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Why is there a gap next to the joint filler?

Young concrete carries on shrinking for a long time, so a semi-rigid filler can part from one face. A top-up normally puts it right.

How soon can traffic go back on the floor?

Cure times vary with the product and the conditions. You’ll get a reopening time for each area when we agree the phasing.

What guarantee do you give on joint filling?

Every job has our 12-month guarantee. It covers our workmanship, not later slab movement or damage from impacts.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Where floor joints take the most wear near Ampfield

The South East is one of the drier parts of the UK. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint. The 3 miles around Ampfield take in at least three named trading estates, business parks or retail parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

For a school such as Ampfield Church of England Primary School, playground and building joints can be done in the holidays. Phasing is what makes joint work possible on busy sites such as Test Valley Business Park (1.8 miles south of Ampfield): one bay, aisle or car park row at a time.

Ampfield is about 2 miles north-west of Chandler's Ford, in Hampshire. We cover commercial sites throughout Ampfield. Ampfield is one of 723 places we cover in Hampshire. Our Southampton page has more on work in that area.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:

  • Worn screed or surface finishes
  • Cracks across panels caused by settlement or overload
  • Level or flatness problems across the floor

If you’re not sure, just give us a call on 01277 525 020 or email the details over and we’ll give you a straight answer.

Where we work in Ampfield

  • Forklift and pallet-truck routes
  • Joints along racking aisles
  • Loading bays
  • Retail and showroom floors
  • Saw-cut induced joints
  • Construction joints

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Plan for a top-up on newer floors
  • Hold traffic back until the product has cured
  • Record damaged joints with a photo and a location
  • Tell us about strong cleaning chemicals before we quote

We’ll give you a time before trucks can run over the new joints and it pays to stick to it. Cones or barriers stop the first driver cutting the corner.

Regular inspection catches failing fills before the edges go. A phased plan, worst routes first, spreads the work out so nothing is left to fail.

Why deal with it now?

A floor coating laid over open joints soon cracks along the joint lines. Joints need their own treatment before or alongside any coating work. Older rural buildings around Ampfield move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

When to call us in Ampfield

Small, hard wheels put a lot of load through a very small area. Where a joint is open, the wheel dips and strikes the far edge, and repeated impacts break the concrete away.

Any of the following is a good reason to get the joints checked over:

  • Joint fill separating from the concrete
  • A rough ride across broken joints
  • Broken arrises where pallet trucks cross
  • Cracked and crumbling joint fill

Hospital campuses such as Romsey Hospital, 2.5 miles to the south-west of Ampfield, grow in stages, leaving movement joints wherever new blocks meet old.

Before you book anyone

  • What level of public liability insurance do they hold?
  • What site paperwork they can supply
  • The terms of the workmanship guarantee
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

Surface by surface

Forklift and pallet-truck routes

A route joint has to take repeated wheel strikes without breaking up. Wheel type and traffic level steer the product choice.

Semi-rigid joint fillers

A semi-rigid fill can separate along one side while a slab is still shrinking. A later top-up normally puts that right and we will flag it at quote stage.

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 a day or more, depending on the metres of joint and how many zones the floor is split into, and we clear our waste as we work. For a building around Ampfield, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. First, the zones and order of work are agreed with you.
  2. Any joints with broken edges are flagged before work starts.
  3. Failed material and debris are removed and the joint cleaned.
  4. The chosen filler or sealant goes in flush with the slab.
  5. You get a time for each zone to reopen.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Have the specification and drawings to hand
  • Flag any permit to work we’ll need
