How we handle expansion joint sealing in Kennington
Brickwork and blockwork walls have vertical movement joints at intervals. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied with primer where the maker calls for it. Most enquiries involve leaks through car park deck joints onto the level below and new sealant over old, now failing, across car park decks and ramps, podiums and floor movement joints and cladding panel joints. One point of contact handles commercial sealant work in Kennington from the first photographs to the final walk-round, whether it’s one building or several.
Around Kennington, most floor and movement joint jobs are single buildings or yards, so we gather photographs and measurements first. That way the right materials come on the day and the job is done in one visit where possible.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

How the job changes by surface
Car park decks and ramps
Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again.
Brickwork and blockwork joints
A brick movement joint full of old mortar or debris can’t close. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.
Diagnose, treat, sign off
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Work in places the size of Kennington is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
What we need from you
- Point out any areas we must not close
- Point out parking and an unloading spot
- Confirm the product named in the specification

What else we do in Kennington
Keeping the joints sound
To get the most from the new sealant:
- Avoid parking heavy plant or pallets on joint lines
- Record the sealant used and the date in the O&M file
- Check joints after long freezing spells
- Report split or peeling joint sealant early
In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers. Keeping the filler or sealant sound protects the floor.
Traffic, movement and joints around Kennington
The South East is one of the drier parts of the UK. 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. Less than 3 miles from Kennington there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
Across sites such as The Oxford Science Park, 1.1 miles east of Kennington, floor and movement joints can be sealed in phases so units keep working. For a centre such as Templars Square, which lies north-east of Kennington, the service yard and car park joints usually need attention first. A campus such as University College (to the north of Kennington) has long runs of movement joint in its buildings, decks and paving.
Kennington is about 3 miles south of Oxford, in Oxfordshire. We send applicators to Kennington for movement joints, handled exactly as we handle every other area. We work across 423 places in Oxfordshire.

When to bring in a specialist
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Why deal with it now?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. We will flag where edges need repair before sealing. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

When something else is needed
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Movement on a scale no sealant is meant to absorb
- Joints too narrow for the movement, which need redesigning by the engineer
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

Common questions from Kennington clients
Is a smaller place like Kennington outside your area?
No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Is Sandford Lane Industrial Estate, near Kennington, within your area?
Yes. Estates, retail parks and business parks around Kennington, Sandford Lane Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
Are expansion joints and movement joints the same thing?
It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing, and either way it needs a sound seal.
Why has the sealant in our expansion joints split?
It depends on how the sealant has let go: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Broken edges are a third possibility.
