About our expansion joint sealing in Netley Marsh
Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. The enquiries we see most involve car park joints leaking onto vehicles below and hardened, cracked sealant on exposed facades, across precast concrete panel joints, car park decks and ramps and podiums and floor movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Netley Marsh, preparation and product choice get the time they need.
For a site near Netley Marsh, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Surface by surface
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing.

Signs you need expansion joint sealing in Netley Marsh
Car park decks and floors face loads that walls never see. Wheel loads stress the sealant and the arrises, while de-icing salts and grit attack the seal. A sealant that isn’t trafficable won’t last there.
It’s worth sending us details if you spot any of the following:
- Joints where the bead has lost adhesion
- Water dripping through deck or ramp joints
- Weathered movement joint sealant that no longer flexes
- Arrises breaking up along floor joints
For a centre such as Totton Shopping Centre (1.8 miles east of Netley Marsh), the service yard and car park joints usually need attention first.

Warehouse floors and decks around Netley Marsh
The sea is no more than about 3 miles from Netley Marsh. Open joints in coastal car parks and yards let in salt-laden water as well as grit, which is why split joints are worth sealing before the edges deteriorate. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints.
Hospital campuses such as Tatchbury Mount Hospital, 1.1 miles to the north of Netley Marsh, grow in stages, leaving movement joints wherever new blocks meet old. Across sites such as South Hampshire Industrial Park, which lies north-east of Netley Marsh, floor and movement joints can be sealed in phases so units keep working.

Leave it or put it right?
On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use, compared with a full closure. Tell us what has to stay open and we’ll plan around it. For buildings around smaller places like Netley Marsh, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Aftercare for building managers
A few simple habits keep the new joints working:
- Plan racking layouts so feet don’t land on a joint
- Keep stones and debris out of open joint lines
- Treat a small split as a warning, not a cosmetic issue
- Reopen bays and walkways only after the stated cure time
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.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Sealing early protects the edges.
On site: what to expect
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. For a building around Netley Marsh, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- 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.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Related advice
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.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Netley Marsh: questions and answers
Is Netley Marsh too far out for you?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Is hospital work, at somewhere like Tatchbury Mount Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What if the joint edges are damaged?
A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. We flag it at the quote stage where we can see it.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can the building stay open while you work?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
