Expansion joint sealing for commercial buildings in Grazeley
Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement, phasing bays so the car park can stay in use. If you have rain penetration at brick or block movement joints and leaks through car park deck joints onto the level below, we can put it right, on precast concrete panel joints, brickwork movement joints and car park decks and ramps alike. Looking for mastic applicators who cover Grazeley? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
For a site near Grazeley, measurements and photographs up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Why deal with it now?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. If the material either side is sound, a properly prepared reseal restores the joint. We’ll flag where edges need repair before sealing. Around Grazeley, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.
The price depends on the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

Our process
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. If others near Grazeley need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- 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.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
What we need from you
- Have the specification and drawings to hand
- Share the asbestos register for older buildings
- Point out any areas we must not close

What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Joints too narrow for the movement, which need redesigning by the engineer
- Leaks coming from the membrane rather than the joint seal
- Proprietary pre-formed expansion joint systems
If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

For managing agents and facilities managers
Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Act on the first tear or lifting edge rather than waiting
- Include every elevation and deck joint in periodic inspections
- Inspect exposed joints once the cold weather has passed
- Keep scrapers and ploughs from dragging across joint sealant
Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it and decks and floors suffer most. Regular sweeping keeps joint lines clear.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors by which time the joint has been open for a while. Catching it early keeps the water outside.

Floors, slabs and movement joints in Grazeley
At least three named trading, business or retail sites lie within about 3 miles of Grazeley. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Rainfall across the South East, Grazeley included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open.
For an estate such as Royal Berkshire Hospital, which lies north of Grazeley, the joints in ramps, decks and long building elevations all need attention over time. At a retail site such as Reading Gate Retail Park, which lies north of Grazeley, trolleys, cages and cars run over floor and slab joints all day. Campuses like University of Reading - Whiteknights Campus, 3.7 miles north-east of Grazeley, mix old and new buildings, with movement joints wherever they meet.

How the job changes by surface
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond.
