About our expansion joint sealing in St Mary Bourne

Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled with primer where the maker calls for it. The enquiries we see most involve joints packed with grit and debris and layers of sealant in a movement joint, on precast concrete panel joints, car park decks and ramps and cladding panel joints. One point of contact handles commercial sealant work in St Mary Bourne from the first photos to the final walk-round, for single jobs and planned programmes alike.

In and around smaller places like St Mary Bourne, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

What happens if it’s left?

Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall. Resealing early keeps the work to sealant. Converted and older buildings near places like St Mary Bourne tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Warehouse floors and decks around St Mary Bourne

St Mary Bourne 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, and gritting in cold spells finds its way into open joints. At about 59 miles from central London, St Mary Bourne is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift.

Sites like Andover War Memorial Hospital (to the south-west of St Mary Bourne) carry ambulances, deliveries and visitors’ cars over their road and deck joints. If you manage units on an estate such as Ardglen Industrial Estate, 2.8 miles to the south-east of St Mary Bourne, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. In a school such as St Mary Bourne Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

When something else is needed

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Damaged metal nosings or cover plates over a joint
  • Movement on a scale no sealant is meant to absorb

If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think.

Surfaces we seal

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

Looking after the joints

Once the work is signed off, a little attention goes a long way:

  • Treat a small split as a warning, not a cosmetic issue
  • Note which joints were done, when, and with what
  • Brief car park operatives to protect joint lines during winter clearance
  • Reopen bays and walkways only after the stated cure time

Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file.

On a multi-storey car park, a failed joint usually shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Resealing early limits the damage.

From enquiry to sign-off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work typically takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Jobs in and around smaller places like St Mary Bourne are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

What we need from you

  • Share your working hours and any access restrictions
  • Tell staff and tenants when we’ll be in
  • Arrange parking or a loading space

Concrete and precast panel joints

Precast and concrete panel joints move daily. The sealant needs the right movement capability and a controlled depth.

Podium joints

Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.

Questions we’re asked in St Mary Bourne

Do you take on work at healthcare sites like Andover War Memorial Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Ardglen Industrial Estate, near St Mary Bourne, within your area?

Yes. Estates, retail parks and business parks around St Mary Bourne, Ardglen Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Can you quote from photographs?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Can you work while the building is occupied?

Usually, yes. We phase the work so most of the building stays in use.

Will you quote for a small job?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

What do you charge?

Each job is quoted on its own details. For yours, phone 01277 525 020 or send details through our quote form with a description of the work.

General trades versus a specialist

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, which is what makes a joint last.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
