How One Contractor Cut 4 Hours Off a Slab Pour Using Neolag

Discover how a Sydney plumbing crew reduced installation time and rework by 50% using Neolag's pre-formed neoprene lagging sleeves.

Time Is Money on a Slab Pour

Ask any plumber what the most stressful day on-site is, and you'll get the same answer: pour day. Everything has to line up perfectly.

Josh and his crew at J Group Plumbing shaved four hours off their job by switching to Neolag.

The Job: 100mm Drainage Pipes Through a 400mm Slab

The team was working on a large multi-storey home where all drainage had to be concealed. Multiple penetrations for drainage and stormwater.

"We had guys spending more time wrapping pipes than actually running them."

— Josh, J Group Plumbing

The Solution: Pre-Formed Neoprene Sleeves

The crew cut Neolag sleeves to length, slid them over the pipes, and positioned everything before inspection.

5 minutes per pipe using Neolag

Across 48 sections, the team saved four hours in a single day.

"Everything was locked in and ready before the inspector even got there. He passed the lot first go."

The Crew's Feedback

"We saved half a day, the boys weren't swearing at tape for once, and it looks clean as. It's a no-brainer."

— Josh, J Group Plumbing

From One Job to Every Job

After that first pour, J Group Plumbing standardized Neolag across all new projects.

Proof That Innovation Saves Time

When one crew can save four hours on a single slab pour, imagine what that means across a full subdivision or commercial build.
