Tests have shown then depending on the situation lunar regolith can go up 80MPa. And the more water is contained, the harder it gets. You get low yield from that, around 10%. So you need to mine a pretty large amount and process it. So you need to create excavator that operate inside a creator that can operate at extrem temperatures. On Mars you can literally do what we already do at the South Pole, drill a hole and make it warm. Its multiple orders of magnitude easier.
