Expansion joint sealing in Sprig's Alley

Joints in car park decks and ramps are among the hardest-working in any building. 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 and the work can be phased so parts of the car park stay open. Site teams most often ask us about joints packed with grit and debris and hardened, cracked sealant on exposed facades, on precast concrete panel joints, podiums and floor movement joints and blockwork control joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Sprig's Alley it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places such as Sprig's Alley, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

When to bring in a specialist

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

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Commercial clients in Sprig's Alley

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Sprig's Alley can sit alongside others in a wider programme.

Cost factors for movement joints

A fixed quote reflects the actual work. It allows for:

  • Access and working height
  • Specialist products, such as fire-rated or hygienic sealants
  • How much existing material needs removing
  • Phasing around occupants

A quote for movement joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

What we need to price the job

A few photographs plus some basic facts will normally do. It helps to include:

  • The site address and postcode
  • What the building is and how it’s used
  • When you need the work done
  • How the joints are reached, and at what height

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. If you have questions first, phone 01277 525 020 or email the details over.

Keeping the joints sound

To get the most from the new sealant:

  • Put movement joints on the planned maintenance inspection round
  • Keep racking legs and heavy point loads off floor joints
  • Brief car park operatives to protect joint lines during winter clearance
  • Record the sealant used and the date in the O&M file

Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records, so the next reseal starts with the facts.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Catching it early keeps the water outside.

Our process

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For work around Sprig's Alley, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Before we start on site

  • Send any specification or drawings in advance
  • Explain the parking and delivery arrangements
  • For older buildings, check the asbestos register before work

Getting a fixed quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Advice

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Leaks coming from the membrane rather than the joint seal
  • Changing the joint layout or spacing of a structure
  • Crumbling edges that would give a new bead nothing sound to grip

If you’re not sure, just call the office on 01277 525 020 or use the quote form and we will give you a straight answer.

What we seal

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

Where floor joints take the most wear near Sprig's Alley

Central London is about 36 miles from Sprig's Alley. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day. Sprig's Alley sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.

Warehouse floors on estates like Junction 5 Bates Industrial Estate, 1.4 miles to the south of Sprig's Alley, carry pallet trucks and forklifts over every saw-cut joint. Another example is Crownfield Industrial Estate, 2.8 miles to the east of Sprig's Alley, where floors and yards would be done in stages around the occupiers. Sites like Thame Community Hospital, 5.6 miles north-west of Sprig's Alley, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Common questions from Sprig's Alley clients

Is Sprig's Alley too far out for you?

Not at all. Sprig's Alley is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Can you work at a site such as Junction 5 Bates Industrial Estate, by Sprig's Alley?

Yes. Estates, retail parks and business parks around Sprig's Alley, Junction 5 Bates Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, as many construction sites ask for.
