FAQs: Southend-on-Sea
Is Tickfield Industrial Estate, near Southend-on-Sea, within your area?

Can you work on a hospital site such as Southend University Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Are you CHAS accredited?

Do you guarantee expansion joint work?
The workmanship is guaranteed for 12 months from sign-off and we hold public liability insurance. Regular sweeping and inspection help the joints last.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How long will the joint resealing take?
It typically takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access and phased work can stretch that to suit your site. We will confirm when each area can be used again.

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

General trades versus a specialist
For most general trades, sealant is a sideline. 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: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Traffic, movement and joints around Southend-on-Sea
Southend-on-Sea is within about 1 mile of the coast. Open joints in coastal car parks and yards let in salt-laden water as well as grit, and edges left open tend to break up faster. Southend-on-Sea is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints.
Schools like Westborough Academy often have long brick elevations with movement joints that age quietly. Phasing is what makes joint work possible on busy sites such as Greyhound Retail Park (0.8 miles east of Southend-on-Sea): one bay, aisle or car park row at a time.

Advice
What happens if it’s left?
Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use without shutting the whole car park. Tell us what has to stay open and we’ll plan around it. On a busy site in a large place like Southend-on-Sea, a failed joint gets worse with every day of use, until a reseal turns into a repair. Catching it early keeps the fix simple.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Surface by surface
Concrete and precast panel joints
Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix and flag it if the membrane looks like the source.
Do you need expansion joint sealing in Southend-on-Sea?
Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch and opens at the next temperature swing.
These are often picked up first by site or facilities staff:
- Damp inside where a wall movement joint has failed
- Expansion joints split through the centre of the bead
- Spalled or broken joint edges in floors and decks
- Joints where the bead has lost adhesion
Large sites such as Southend University Hospital, 0.6 miles to the north-west of Southend-on-Sea, have car parks, service roads and long elevations with movement joints in brick and panels.
Before you book anyone

- Will RAMS and insurance details be available?
- Their pre-qualification and accreditations
- Which product they’ll use, and why it suits the joint
Looking after the joints
For the best life from the joints:
- Keep traffic off new joints until the cure time is up
- Check joints after long freezing spells
- Treat a small split as a warning, not a cosmetic issue
- Inspect movement joints alongside other routine building checks
Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.
Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors by which time the joint has been open for a while. Catching it early keeps the water outside.
