Traffic, movement and joints around Up Somborne

Central London is about 64 miles from Up Somborne. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. The South East is one of the drier 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.

For buildings at a park such as Balldown Business Centre, which lies east of Up Somborne, brick and panel movement joints are easy to forget until one leaks. A campus such as University of Winchester, 5 miles to the south-east of Up Somborne, has long runs of movement joint in its buildings, decks and paving.

How we handle expansion joint sealing in Up Somborne

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. 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. Most enquiries involve brittle, chalky sealant on external joints and torn sealant in brick or block movement joints, on precast concrete panel joints, cladding panel joints and blockwork control joints. A single leaking joint is often how a building in Up Somborne first comes to us: we look at the rest while we are there and tell you what we find.

Jobs around smaller places like Up Somborne are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Doing it in-house

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Honest limits

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Waterproofing layers buried beneath the sealant
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Movement on a scale no sealant is meant to absorb

If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Questions we are asked in Up Somborne

Does your area include sites such as Balldown Business Centre, near Up Somborne?

Yes. Estates, retail parks and business parks around Up Somborne, Balldown Business Centre among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Is Up Somborne too far out for you?

No. Places such as Up Somborne 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.

Why do our movement joints keep failing?

Normally the joint is moving more than the sealant can take. That’s why we check width, depth and movement class before quoting.

Can staff carry on working while you are here?

In the majority of cases, yes. We phase the work so most of the building stays in use.

Are you fully insured?

Yes. We are fully insured, and the certificate can go with your quote.

Are expansion joints and movement joints the same thing?

The general name is movement joint, and expansion joint is one common type. In everyday use the two names are often swapped, and the sealing method is much the same.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Leave it or put it right?

Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now because damage continues. We can split the scope into urgent and planned. Older rural buildings around Up Somborne move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Pricing movement joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

Building owners, agents and FMs in Up Somborne

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

How the job changes by surface

Concrete and precast panel joints

Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.

Joints between different materials

Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces priming where the maker calls for it.

On site: what to expect

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Up Somborne can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Share your working hours and any access restrictions
  • Let us know about inductions and permits
