Maintenance after handover

After handover, these steps help:

  • Leave barriers in place until fresh joint sealant has cured
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Keep racking legs and heavy point loads off floor joints
  • Look over external and deck joints after a hard winter

Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers. Sealing early protects the edges.

Expansion joint sealing in Deane, done properly

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, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement, phasing bays so the car park can stay in use. If you are dealing with sealant pulling off the joint face and chipped joint edges on forklift routes, we can put it right, whatever the surface. Most enquiries from Deane start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Smaller community and commercial buildings around Deane have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

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.

Why it’s worth doing now in Deane

Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex, so it fails quickly. Full removal and preparation is in every quote. Around Deane, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Joints that move: notes for Deane

Deane is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints. Central London is about 51 miles from Deane. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.

Around Deane, each joint gets a filler or sealant matched to what crosses it and how much it moves. Hospital campuses such as Park Prewett Hospital, 4.8 miles to the north-east of Deane, grow in stages, leaving movement joints wherever new blocks meet old.

Deane is about 5 miles west of Basingstoke, in Hampshire. Anywhere in RG25, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Deane is one of 723 places in Hampshire on our list for movement joints. There’s a separate page for Reading, roughly 17 miles from Deane.

Anyone looking for expansion joint sealing in RG25 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

What the job involves on each surface

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. We use a sealant made for wheel loads and the expected movement with bays done in phases so the car park keeps running.

Brickwork and blockwork joints

A brick movement joint full of old mortar or debris can’t close. Everything is raked out before backing and sealant go in.

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Deane need work, visits can be combined. A fixed quote is given before anything starts.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Each joint is inspected and handed over with our 12-month guarantee.

What sets the cost

The price varies from site to site. It mainly depends on:

  • Quantities, in metres or numbers
  • Travel to remote or island sites
  • Removal of failed or old sealant
  • How accessible the joints are

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

What to include in your enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • How the joints are reached, and at what height
  • Photos of the joints, close up and from further back
  • The postcode of the building
  • Any specification or named product

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, phone 01277 525 020 or email a schedule or drawings.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

There’s also the paperwork. 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.

Questions about Deane

Do you take on work at healthcare sites like Park Prewett Hospital?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Will our site in Deane have to close for joint sealing?

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.

Can the sealant be colour-matched?

It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

What’s the difference between an expansion joint and a movement joint?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint.

What causes movement joint sealant to fail?

The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. Working out the cause comes first, because the fix differs.
