Expansion joint sealing in Barbican Estate
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. A sealant suited to traffic and the expected movement goes in and the work can be phased so parts of the car park stay open. The enquiries we see most involve brittle, chalky sealant on external joints and sealant pulling off the joint face, on blockwork control joints, podiums and floor movement joints and brickwork movement joints. A single leaking joint is often how a building in Barbican Estate first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. In Barbican Estate, as everywhere in London, access, loading and the ULEZ all come into the plan.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Why deal with it now?
Spot repairs can be useful on a tight budget. The remaining sealant is often close to failing too. Where it helps, we quote both options. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
A quote for movement joints depends on quantities, condition and access. Call for a quote.

Looking after the joints
Cleaning and maintenance staff play a part too. Pass these on to them:
- Clear dirt from joint lines during routine cleaning
- Reopen bays and walkways only after the stated cure time
- Look over external and deck joints after a hard winter
- Raise snow-clearing blades over deck joints where possible
Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears, especially on car park decks and warehouse floors. Regular sweeping keeps joint lines clear.
When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort, so the work can be planned rather than rushed. We can suggest an order, worst joints first.
Questions about Barbican Estate
Do you take on jobs in Barbican Estate where loading and access are tightly controlled?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Does your area include sites such as Southwark Bridge Business Centre, near Barbican Estate?
Yes. Estates, retail parks and business parks around Barbican Estate, Southwark Bridge Business Centre among them, are all within reach. Photos and a short description are enough for a first look.
What if the joint edges are damaged?
Sealant needs sound faces to bond to, so we will tell you if the edges need repairing before sealing. We flag it at the quote stage where we can see it.
Can the sealant be colour-matched?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
Which product is best for expansion joints?
Movement capability matters most, classified under BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
Signs you need expansion joint sealing in Barbican Estate
Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600.
Look out for the following:
- Rain penetration at brick or block movement joints
- Joints packed with grit and debris
- Layers of sealant in a movement joint
- Expansion joints split through the centre of the bead
Another example is Grand Vitesse Industrial Estate, 1.1 miles to the south of Barbican Estate, where floors and yards would be done in stages around the occupiers.
Before you book anyone
- Health and safety accreditation such as CHAS
- Their plan for phasing and protecting the area
- Is the sealant right for the movement and the substrate?
- Will RAMS and insurance details be available?

Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. All of Greater London is in the ULEZ, and kerbside space in Barbican Estate can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Each joint is inspected and handed over with our 12-month guarantee.
Preparing the site
- Let building users know which areas are affected
- Agree which areas must stay open
- Confirm the product named in the specification

Advice
What the job involves on each surface
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement flagging broken arrises before sealing.
Cladding panel joints
Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately.
