About our expansion joint sealing in Frogham

Long runs of brick or block have movement joints built in that most people only notice when the sealant has gone. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied with primer where the maker calls for it. If you have spalled or broken joint edges in floors and decks and water dripping through deck or ramp joints, we can put it right, whatever the surface. Most enquiries from Frogham start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

In and around smaller places like Frogham, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

After the work

Cleaning and maintenance staff play a part too. Share these points with them:

  • Brief car park operatives to protect joint lines during winter clearance
  • Act on the first tear or lifting edge rather than waiting
  • Check joints after long freezing spells
  • Keep stones and debris out of open joint lines

On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal.

On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. That water often carries de-icing salts with it, which is bad news for the concrete and the people parking below. Sealing the joint promptly stops it at source.

Why it’s worth doing now in Frogham

On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open. We agree phasing with you before work starts. For buildings around smaller places like Frogham, 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. Renewing joints in good time avoids the problem.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Traffic, movement and joints around Frogham

The 3 miles around Frogham take in two named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint.

For a school such as Hyde Church of England Primary School, playground and building joints can be done in the holidays. For an occupier at a site such as Arch Farm Industrial Estate (2.3 miles north-west of Frogham), the joints at loading doors and dock levellers typically see the hardest wear.

Frogham is in Hampshire. We cover commercial sites throughout Frogham, for single jobs and planned programmes alike. 723 places across Hampshire fall within our area, Frogham among them. Southampton is covered too, some 16 miles away.

Questions we’re asked in Frogham

Do you cover business parks and estates near Frogham, such as Arch Farm Industrial Estate?

Yes. Our area takes in Frogham and its surroundings, with estates and business parks such as Arch Farm Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.

Is Frogham too small for you to travel to?

No. Places such as Frogham are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Which product is best for expansion joints?

We choose a sealant with a movement capability that suits the joint, classified under BS EN ISO 11600. Where two different materials meet, a hybrid sealant can be the better choice.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

How long does movement joint sealing take?

The metres of joint, the access and the amount of removal decide it. Typically it takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access.

Are you fully insured?

Yes. We are fully insured, including public liability cover.

Our process

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and we clear our waste as we work. Jobs in and around smaller places like Frogham are normally planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

Advice

Common problems we fix in Frogham

Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way, so we check width and movement before quoting.

These are often picked up first by site or facilities staff:

  • Torn sealant in brick or block movement joints
  • Water dripping through deck or ramp joints
  • Debris jammed in movement joints
  • Brittle, chalky sealant on external joints

Phasing is what makes joint work possible on busy sites such as Fordingbridge Business Park (2.4 miles west of Frogham): one bay, aisle or car park row at a time.

How to choose a sealant contractor

Different surfaces, different methods

Brickwork and blockwork joints

A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing.

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.

Work for main contractors and building owners

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.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.
