 Re: has anyone ever used an air spade?
Sean said they use a 180cfm compressor not 180psi.
You need a huge volume or capacity to have a continual blast of air running out of a 5/16" hole.
I have a large domestic compressor that can crank 140psi but it only has 13cfm capacity so I run out of air fast and the pump is going flat out.
A 180cfm compressor is one of those petrol driven jobs you tow around with the big fat hoses, you need that for the volume of air that will be going through your air spade.
Would be a messy job and off the record I heard on the grape vine that decompacting is down the line from mulching ... some prefer to see you mulch rather than fragment the root system as the soil fractures many of the finer roots will be broken as they are attached to the soil. But in saying that if you have a compacted surface you cannot mulch then you dont have many choices than to decompact.
Watering will add to compaction if weight is put on by traffic/people etc afterwards. |
