Expansion joint sealing in Lacasaidh

How we handle expansion joint sealing in Lacasaidh

The seal is what lets a movement joint do its job. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on blockwork control joints, podiums and floor movement joints and brickwork movement joints, and the usual reasons a site gets in touch are arrises breaking up along floor joints and rain penetration at brick or block movement joints. One point of contact handles commercial sealant work in Lacasaidh from the first photographs to the final walk-round, for single jobs and planned programmes alike.

For outside joints near Lacasaidh, the Scottish weather sets the timetable: dry faces and the right temperature are essential. Internal floors can be done whenever suits the site.

A 12-month guarantee applies to all our work. Should something we installed fail, call 01277 525 020 or send photos by email and we’ll come back to it.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

• Crumbling edges that would give a new bead nothing sound to grip
• Movement on a scale no sealant is meant to absorb
• Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

If in doubt, phone 01277 525 020 or send details through our quote form and we’ll say what we think.

What we are called out for in Lacasaidh

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.

Site and facilities staff are often the first to spot these:

• Water getting into the wall through a failed joint
• Spalled or broken joint edges in floors and decks
• Weathered movement joint sealant that no longer flexes
• Sealant pulling off the joint face

In and around Lacasaidh, the right filler or sealant for each joint depends on the traffic and the movement it takes.

What to look for in a quote

• How they handle RAMS and site documents
• Their approach to joint depth and backing
• The terms of the workmanship guarantee
• Whether old or failed sealant will be cut out, not overlaid

Our contractor checklist

Maintenance after handover

A few simple habits keep the new joints working:

• Avoid parking heavy plant or pallets on joint lines
• Put movement joints on the planned maintenance inspection round
• Look over external and deck joints after a hard winter
• Raise snow-clearing blades over deck joints where possible

Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint and we’ll tell you when each bay or area can reopen. Barriers left in place until then protect the finish.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Sealing early protects the edges.
