How we handle expansion joint sealing in Three Ashes
Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels. If the arrises are already broken, we will say so before sealing and phasing can keep areas working. We work on car park decks and ramps, podiums and floor movement joints and precast concrete panel joints, and the usual reasons a site gets in touch are leaks through car park deck joints onto the level below and expansion joints filled with dirt and stones. Facilities teams, main contractors and managing agents in Three Ashes tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places such as Three Ashes, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Surface by 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.
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. We use a sealant classed for the movement, laid over backing to depth.

Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Check joints after long freezing spells
- Act on the first tear or lifting edge rather than waiting
- Keep stones and debris out of open joint lines
- Brief car park operatives to protect joint lines during winter clearance
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.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort so you can prioritise and budget. We’ll tell you which movement joints need doing now and which can wait.
Our process
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and our waste is bagged and taken away as we go. Smaller jobs around Three Ashes can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Preparing the site
- Tell staff and tenants when we’ll be in
- Have the specification and drawings to hand
- Send asbestos survey details if the building is pre-2000

When something else is needed
Being straight saves everyone time. Fresh joints won’t solve:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Changing the joint layout or spacing of a structure
- Leaks coming from the membrane rather than the joint seal
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Three Ashes: questions and answers
Do you take on work at healthcare sites like Basingstoke and North Hampshire Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Three Ashes too small for you to travel to?
No. Places such as Three Ashes are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
What happens if it rains on the day?
Outside work depends on conditions. Indoor joints can normally carry on regardless.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Can you quote from photos?
It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs usually get a visit.
Traffic, movement and joints around Three Ashes
Three Ashes sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open. At about 44 miles from central London, Three Ashes is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.
Another example is Stacey Industrial Park, 2.2 miles to the north-west of Three Ashes, where floors and yards would be done in stages around the occupiers. For an estate such as Basingstoke and North Hampshire Hospital, 4.8 miles to the south of Three Ashes, the joints in ramps, decks and long building elevations all need attention over time.

Signs you need expansion joint sealing in Three Ashes
Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch.
Most enquiries start with one or more of the following:
- Leaks through car park deck joints onto the level below
- Water getting into the wall through a failed joint
- Sealant peeling off one face of the joint
- Arrises breaking up along floor joints
In a school such as Silchester Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
Before you book anyone
- Do they follow the manufacturer’s priming guidance?
- Which product they’ll use, and why it suits the joint
- Whether their applicators hold CSCS cards
- Whether old or failed sealant will be cut out, not overlaid
Why deal with it now?
Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open without shutting the whole car park. Tell us what has to stay open and we will plan around it. Halls, stores and units around places like Three Ashes may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
