Expansion joint sealing for commercial buildings in Mochrum

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels. If the arrises are already broken, we’ll say so before sealing, and phased work keeps areas in use. The enquiries we see most involve brittle, chalky sealant on external joints and spalled or broken joint edges in floors and decks, across podiums and floor movement joints, brickwork movement joints and precast concrete panel joints. A specialist sealant contractor works differently from a general builder: in Mochrum, that means joint design, primers and backing rod as standard.

In smaller places such as Mochrum, the joints we’re asked about sit in workshops, farm sheds, schools and halls. Concrete slabs and yards there take vehicles and weather.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Do you need expansion joint sealing in Mochrum?

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears.

Common reasons buildings call us in:

  • Water getting into the wall through a failed joint
  • Leaks through car park deck joints onto the level below
  • New sealant over old, now failing
  • Movement joints with split or torn sealant

For floors and slabs around Mochrum, the product is chosen for the traffic and the movement at each joint.

Questions to ask before you book

  • Do they follow the manufacturer’s priming guidance?
  • Their approach to joint depth and backing
  • Their pre-qualification and accreditations
  • Who will actually carry out the work

Choosing a commercial sealant contractor

When something else is needed

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

  • Proprietary pre-formed expansion joint systems
  • Concrete or masonry repairs along the arrises
  • Leaks coming from the membrane rather than the joint seal

If in doubt, call the office on 01277 525 020 or email the details over and we’ll say what we think.

What we seal

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

Owners, agents and contractors

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Our process

Site rules come first: 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. Tell us who will meet us and how to get in at your building near Mochrum. We will confirm the plan with the fixed quote.

  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 tell you if the design looks wrong for the movement.
  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. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Move anything stored against the joints
  • Tell us which areas need to stay in use

Advice

Mochrum: questions and answers

Our building in Mochrum is near the coast: does that change the sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

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

Usually not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.

Do you reseal car park expansion joints?

Yes. Let us know the opening hours and which levels or bays have to stay available.

Can you seal joints in cold or wet weather?

Weather matters for any external joint. Indoor joints can typically carry on regardless.

Are expansion joints and movement joints the same thing?

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.

Do you work in Mochrum?

Yes. We take on work across Mochrum, with one number for every area we cover.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

What sets the cost

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

  • Backing rod, priming and other preparation
  • How accessible the joints are
  • Whether old sealant has to be cut out first
  • The total length or number of joints

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What we need to price the job

There’s no need for a formal survey. These details are enough to start:

  • Specification clauses that apply
  • Any dates the work must fit around
  • Whether an asbestos survey exists
  • The type of building and who uses it

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or ring 01277 525 020 or email us to discuss it first.

Traffic, movement and joints around Mochrum

Mochrum sits close to the coast, within about 2 miles. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, and edges left open tend to break up faster. The west of Scotland, where Mochrum is, gets more rain than the east. Open joints in external slabs take a lot of water. External sealing is booked for dry spells, with some give in the dates.

Around Mochrum, open joints collect water and debris, and the arrises are the next to go; we will tell you if the edges need repairing first.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
