Expansion joint sealing for commercial buildings in Rivenhall

We’ve been sealing expansion and movement joints for over 20 years for contractors, facilities managers and owners. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. Most enquiries involve spalled or broken joint edges in floors and decks and brittle, chalky sealant on external joints, across podiums and floor movement joints, blockwork control joints and brickwork movement joints. Whoever orders the work in Rivenhall, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Smaller community and commercial buildings around Rivenhall have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Site staff or a sealant specialist?

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.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

When something else is needed

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Leaks coming from the membrane rather than the joint seal
  • Damaged metal nosings or cover plates over a joint

If in doubt, phone 01277 525 020 or email us and we’ll say what we think.

Joints and surfaces we work on

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

How a job runs

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For work around Rivenhall, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We look at the joints, their width and how they’ve failed.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Preparing the site

  • Confirm the product named in the specification
  • Warn occupants and staff about the work
  • Move anything stored against the joints

Expansion joint sealing in Rivenhall: the local picture

Rivenhall sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in. Rivenhall lies roughly 39 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London.

In a school such as Rivenhall Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Hospitals like William Julien Courtauld Hospital, 5.6 miles to the north-west of Rivenhall, have multi-storey or surface car parks whose joints carry vehicles round the clock.

What we’re called out for in Rivenhall

On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while de-icing salts and grit attack the seal. A sealant that isn’t trafficable won’t last there.

These are often picked up first by site or facilities staff:

  • Water dripping through deck or ramp joints
  • Rain penetration at brick or block movement joints
  • Joints packed with grit and debris
  • New sealant over old, now failing

On industrial estates such as Gold Key Industrial Estate, which lies east of Rivenhall, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

Questions to ask before you appoint anyone

Your questions answered

Is a hospital such as William Julien Courtauld Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Is Rivenhall too small for you to travel to?

Not at all. Rivenhall is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

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.

What causes movement joint sealant to fail?

Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. Working out the cause comes first.

Does weather matter for sealant work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Is movement joint sealing guaranteed?

It’s backed by our 12-month guarantee. Tell us right away if a joint we sealed gives trouble in that time.

What affects the price in Rivenhall

A fixed quote reflects the actual work. It takes account of:

  • Induction, permit and paperwork requirements
  • Travel to remote or island sites
  • How much existing material needs removing
  • Backing rod, priming and other preparation

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What to include in your enquiry

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

  • Anything awkward about access or site hours
  • Any dates the work must fit around
  • The site address and postcode
  • Approximate linear metres or a joint schedule

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or email us.

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
