Revision shaft as a tripping hazard

Hello,

I hope I have found the right forum here.

A few years ago, we bought a house that is now about 30 years old. In front of the house, there are some parking spaces for vehicles. The entire area is paved.
Under the paving, there is also the inspection shaft. This protrudes a few centimeters, making it quite a tripping hazard. I assume that the paving stones have settled somewhat over the years.

Are there options to "lower" or "shorten" the inspection shaft so that the paving can be preserved?
If yes, what kind of companies do such work?

Thanks and regards
Michael

Hello,

that probably also depends on how the inspection shaft is constructed. Maybe take a picture inside the shaft and of the surroundings.

Ours (new) consists, for example, of a kind of KG pipe and is height-adjustable. When paving, we cut the surrounding stones at the top so that the cover rests on all four sides by about one centimeter and is flush at the top. This basically excludes any sinking or rising.

Normally, you should be well looked after for such work by a civil engineer or landscape gardener.

Inspection shafts often have concrete rings below the cover. They come in different thicknesses and can be replaced.

If it is really just a minimal edge, these rings can also be ground down. You just have to make sure to restore the joint at the end.
