Expansion joint sealing for commercial buildings in Liss
Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic and we name it in the quote. If you have water dripping through deck or ramp joints and expansion joints filled with dirt and stones, we can put it right, whatever the surface. Whoever orders the work in Liss, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
In a smaller place such as Liss, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Concrete floors and yards in these buildings move and crack like any others.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

After the work
A few simple habits keep the new joints working:
- Record the sealant used and the date in the O&M file
- Keep stones and debris out of open joint lines
- Inspect exposed joints once the cold weather has passed
- Act on the first tear or lifting edge rather than waiting
Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth. Keeping the area coned off until then avoids tyre marks and damage.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint, well after the seal first opened. Resealing promptly prevents internal damage.
Common problems we fix in Liss
Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600.
Typical triggers for a call:
- Leaks through car park deck joints onto the level below
- Debris jammed in movement joints
- Previous reseals laid over old sealant
- Weathered movement joint sealant that no longer flexes
Parks like Ham Barn Business Park (1.3 miles north-west of Liss) combine paved areas, car parks and building elevations, each with joints that move.

Questions about Liss
Do you cover business parks and estates near Liss, such as Ham Barn Business Park?
Yes, sites like Ham Barn Business Park are within our area, along with the rest of Liss. Send details of the unit and the work through our quote form for a quick quote.
Can you work on a hospital site such as Petersfield Community Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Can the building stay open while you work?
In most cases, yes. We phase the work so most of the building stays in use.
What causes movement joint sealant to fail?
The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. Working out the cause comes first since each needs a different fix.
Slabs, ramps and loading bays in Liss
Central London is about 47 miles from Liss. Warehousing clusters around the motorways that ring and radiate from London. Rainfall across the South East, Liss included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint.
Large sites such as Petersfield Community Hospital, 3.6 miles south-west of Liss, have car parks, service roads and long elevations with movement joints in brick and panels. Another example is Upper Adhurst Industrial Park (1.6 miles south of Liss), where floors and yards would be done in stages around the occupiers.

How the job changes by surface
Car park decks and ramps
Car park joints are some of the hardest-working joints in any building. We use a sealant made for wheel loads and the expected movement, phased so parts of the car park stay open.
Podium joints
Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.
Why deal with it now?
Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up. Resealing early keeps the work to sealant. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and we clear our waste as we work. If neighbouring businesses or buildings around Liss need work too, visits can be combined. Tell us your site hours and we will plan around them.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
Getting the site ready
- Let building users know which areas are affected
- Arrange parking or a loading space
