SOME lava rock is porous.... But remember adze rock is also lava.... The dense core of an a'a flow can be some of the more dense basalt rocks... (Bluerock is a name for this dense basalt... & there are usually layers of it on (under) most areas...
IF this stuff was easy to deal with, there would be no need for D-9 & D-10 bulldozers with weld reinforced plates.... this stuff is tough to work with, and it was only when the humungo sized bulldozers were bought here that this rock could be worked.
This is the only place I have lived where the size of a bulldozer used on your lot is normal conversation - I was at a tea where ladies were discussing D-9s & D-10's... without any further reference & everyone knew what was being talked about.... I am pretty sure no where else but Hawaii would this be so...
