Joints that move: notes for Hensting
Hensting is about 62 miles from central London. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day. Hensting has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
Phasing is what makes joint work possible on busy sites such as Vicarage Farm Business Park (1.6 miles south of Hensting): one bay, aisle or car park row at a time. A campus such as University of Winchester, 4.5 miles north of Hensting, has long runs of movement joint in its buildings, decks and paving.
Hensting is about 3 miles north-east of Eastleigh, in Hampshire. We send applicators to Hensting for movement joints. Hensting is one of 723 places we cover in Hampshire. Sites around Southampton have their own page, about 7 miles away.

Expansion joint sealing in Hensting
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed 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 Hensting. We work on blockwork control joints, podiums and floor movement joints and precast concrete panel joints, and the usual reasons a site gets in touch are damp inside where a wall movement joint has failed and weathered movement joint sealant that no longer flexes. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Hensting is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In and around smaller places like Hensting, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
Every job we finish is backed by a 12-month workmanship guarantee, in Hensting as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Do you need expansion joint sealing in Hensting?
On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while grit and salts work into any gap. A sealant that isn’t trafficable won’t last there.
Common reasons buildings call us in:
- Expansion joints filled with dirt and stones
- Arrises breaking up along floor joints
- Expansion joints split through the centre of the bead
- New sealant over old, now failing
A healthcare site such as Wessex Hospital, 3 miles to the west of Hensting, depends on car parks, ramps and service yards whose joints take traffic all day.

What sealant work can’t fix
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Proprietary pre-formed expansion joint systems
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

How the job changes by surface
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.
Concrete and precast panel joints
Precast and concrete panel joints move daily. The sealant needs the right movement capability and a controlled depth.
Your questions answered
Is Hensting too small for you to travel to?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Would you work within a site like Wessex Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Our process
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For work around Hensting, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- 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.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
