Traffic, movement and joints around Broadwater
With the shore within about 2 miles, Broadwater counts as a coastal location. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, which is why split joints are worth sealing before the edges deteriorate. Central London is about 48 miles from Broadwater. The roads out of London are lined with trade parks and distribution sheds.
Sites like Worthing Hospital, 0.9 miles south-east of Broadwater, carry ambulances, deliveries and visitors’ cars over their road and deck joints. On a site such as Downlands Business Park, which lies north-east of Broadwater, the movement joints are in car park slabs, paving and building elevations.

Expansion joint sealing in Broadwater, done properly
Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking and the seal across each one keeps out water and grit. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors on sites in Broadwater. Most enquiries involve water dripping through deck or ramp joints and damp inside where a wall movement joint has failed, on car park decks and ramps, cladding panel joints and blockwork control joints. Looking for mastic applicators who cover Broadwater? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Around Broadwater, most floor and movement joint jobs are single buildings or yards, so we gather photographs and measurements first. Getting widths, depths and traffic details up front means one visit, not two.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Signs you need expansion joint sealing in Broadwater
When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes, and it’s common on joints sealed in a hurry.
What tends to prompt an enquiry:
- Weathered movement joint sealant that no longer flexes
- Expansion joints split through the centre of the bead
- Sealant peeling off one face of the joint
- Car park joints leaking onto vehicles below
At places like Rectory Farm Road Business Park, 1.6 miles east of Broadwater, joints are sealed a section at a time so operations carry on.
Before you book anyone
- Do they follow the manufacturer’s priming guidance?
- Whether old or failed sealant will be cut out, not overlaid
- Who will actually carry out the work
- How they handle RAMS and site documents
On site: what to expect
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. Several jobs near Broadwater can be grouped on one trip. Mention the building’s opening times and we will work within them.
- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Each joint is inspected and handed over with our 12-month guarantee.
What we need from you
- Point out any areas we must not close
- Warn occupants and staff about the work

Advice
Maintenance after handover
To get the most from the new sealant:
- Keep traffic off new joints until the cure time is up
- Look over external and deck joints after a hard winter
- Treat a small split as a warning, not a cosmetic issue
- Note which joints were done, when, and with what
Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead.
When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one, so the work can be planned rather than rushed. We can suggest an order, worst joints first.
Questions about Broadwater
Will you take on work at estates like Downlands Business Park, close to Broadwater?
Yes. Our area takes in Broadwater and its surroundings, with estates and business parks such as Downlands Business Park included. To start, just call the office on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Would you work within a site like Worthing Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
What causes movement joint sealant to fail?
Normally the joint is moving more than the sealant can take. That’s why we check width, depth and movement class before quoting so the same failure isn’t repeated.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you seal car park deck joints?
Yes, we do. These joints take wheels, salt and water, so product choice matters.

Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
What happens if it’s left?
Spot repairs can be useful on a tight budget. The remaining sealant is often close to failing too and repeated access costs add up. Where it helps, we quote both options. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
