Tamping hardcore in an enclosed space?

[autopoiesis]

Hi,

Separate thread as different topic/angle on this thread: //www.diynot.com/forums/building/concrete-raft-for-3-ton-water-tank-how.380075/, where I seek advice on construction of a sturdy concrete raft in an enclosed space.

How can hardcore be adequately compacted, given that petrol-powered tampers can't be used?

Do electric wacker plates exist? Or is having at it with a sledge hammer the only way (or even effective)?

Hope you can advise.

Best wishes,
AP

Use the back of a shovel or a hand compactor.

I've used one and they are a good bit of kit. Easy to use and no fumes.

Thank you all, guys.

No-one around here had heard of an electric compactor, so I picked up a manual one per Simon's and noseall's posts.

Good to know that electric ones exist though, thank you John.

Best wishes,
