Advice re compacted gratefully received!

Hi. I am a 70 Yr old woman doing up my patio with the physical help of a handyman. We have reached the stage where we are compacting down hardcore. I bought an old compacter off Ebay because hiring all the equipment is so expensive and I have other work to do at the bottom of my long garden. Some helpful harbinger of doom has said that the compacter could damage my garden wall, well head and underlying services. There aren't any underlying services as we have dug the area over. Can someone put our mind at rest on this please? If used properly I don't see why it should. The walls have concrete bases. I doubt the well head has but we could concrete round it. See pic of old compacter.Thanks.

Nope - no need to worry. The guidance is you shouldn't mechanically compact over a service unless you have 400mm of cover... in reality this never happens. Just compact in 100mm layers and don't let the compacter sit stationary on or near any services or structures... keep it moving at all times. If you are going over any newly laid ducts, first back fill with dust and manually compact to 100mm before letting the compactor anywhere near it.
