Expansion joint sealing across Sheffield Bottom

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Keeping the joints sound

Regular inspection catches problems early. Specifically:

  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Include every elevation and deck joint in periodic inspections
  • Avoid parking heavy plant or pallets on joint lines
  • Inspect exposed joints once the cold weather has passed

Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it, especially on car park decks and warehouse floors. A routine sweep is the simplest protection.

Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one. We can suggest an order, worst joints first.

Expansion joint sealing in Sheffield Bottom

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; water dripping through to the deck below is often the first sign. We reseal deck and ramp joints with a trafficable sealant chosen for the movement. If you have new sealant over old, now failing and expansion joints split through the centre of the bead, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Sheffield Bottom is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Jobs around smaller places like Sheffield Bottom are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Questions about Sheffield Bottom

Is Theale Lakes Business Park, near Sheffield Bottom, within your area?

Yes, sites like Theale Lakes Business Park are within our area, along with the rest of Sheffield Bottom. Send details of the unit and the work through our quote form for a quick quote.

Is a smaller place like Sheffield Bottom outside your area?

No. Places such as Sheffield Bottom are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Can you seal car park deck joints?

Yes. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed.

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. Removing asbestos is a job for asbestos specialists, not us.

Are expansion joints and movement joints the same thing?

They’re closely related. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.

What the job involves on each surface

Podium joints

Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement, and confirm it in the quote.

Quoting for work in Sheffield Bottom

To price the job, we consider:

  • Distance, for remote addresses
  • Which sealant the job calls for
  • Phasing around occupants
  • The size and state of each joint

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Details that help us quote

The more we know, the firmer the quote. Helpful details to send:

  • Any dates the work must fit around
  • The postcode of the building
  • Anything awkward about access or site hours
  • What the building is and how it’s used

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or give us a call on 01277 525 020 or email us if you’d rather talk the job through.

When to bring in a specialist

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Warehouse floors and decks around Sheffield Bottom

Sheffield Bottom 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. At about 42 miles from central London, Sheffield Bottom is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds.

Retail centres such as Meadway Shopping Centre (2.7 miles north-east of Sheffield Bottom) have floors, service yards and car parks with joints under constant traffic. A healthcare site such as Prospect Park Hospital (to the north-east of Sheffield Bottom) depends on car parks, ramps and service yards whose joints take traffic all day. For buildings at a park such as Theale Lakes Business Park, under half a mile west of Sheffield Bottom, brick and panel movement joints are easy to forget until one leaks.

Sheffield Bottom is about 4 miles south-west of Reading, in West Berkshire. Looking for expansion joint sealing in Sheffield Bottom? We can help, as we do across West Berkshire. Across West Berkshire, 140 places are covered, Sheffield Bottom among them.

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Cracking or settlement that calls for an engineer’s assessment
  • Waterproofing layers buried beneath the sealant

Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Surfaces we seal

  • Brickwork movement joints
  • Car park decks and ramps
  • Cladding panel joints
  • Podiums and floor movement joints
  • Blockwork control joints
  • Precast concrete panel joints

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. Jobs in and around smaller places like Sheffield Bottom are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  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. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Preparing the site

  • Move anything stored against the joints
  • Explain the parking and delivery arrangements
  • Let building users know which areas are affected
