Traffic, movement and joints around Round Bush
Less than 3 miles from Round Bush 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. Round Bush 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, and gritting in cold spells finds its way into open joints.
Hospitals like Spire Bushey Hospital (2.5 miles south of Round Bush) have multi-storey or surface car parks whose joints carry vehicles round the clock. At places like Greycaine Industrial Estate (1.8 miles west of Round Bush), joints are sealed a section at a time so operations carry on. For an occupier at a site such as Otters Pool Way Industrial Estate, 1 mile west of Round Bush, the joints at loading doors and dock levellers usually see the hardest wear.
Round Bush is about 2 miles north of Bushey, in Hertfordshire. Our applicators travel to Round Bush for work on movement joints. Round Bush is one of 371 places we cover in Hertfordshire for movement joints. There’s a separate page for London, roughly 16 miles from Round Bush.

Surface by surface
Joints between different materials
Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement.
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement, phased so parts of the car park stay open.

General trades versus a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
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.
When it isn’t the sealant
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Damaged metal nosings or cover plates over a joint
If in doubt, phone 01277 525 020 or email drawings and photos and we will say what we think before you book.

Looking after the joints
For the best life from the joints:
- Include every elevation and deck joint in periodic inspections
- Report split or peeling joint sealant early
- Keep scrapers and ploughs from dragging across joint sealant
- Note which joints were done, when, and with what
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file, so the next reseal starts with the facts.
On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles. Sealing the joint promptly stops it at source.
Round Bush: questions and answers
Can you work at a site such as Otters Pool Way Industrial Estate, by Round Bush?
Yes. Our area takes in Round Bush and its surroundings, with estates and business parks such as Otters Pool Way Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Is Round Bush too far out for you?
No. Places such as Round Bush are covered as much as the big towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Why do our movement joints keep failing?
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. Sometimes the edge material itself has failed.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
What if the joint edges are damaged?
Broken arrises have to be put right before resealing. Sealing over them leads to early failure.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and we clear our waste as we work. For work around Round Bush, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- First, the joints are inspected for width, movement and the type of failure.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry.
- 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.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Preparing the site
- Tell staff and tenants when we’ll be in
- Share your working hours and any access restrictions
- Arrange parking or a loading space
