$ASCK is not in the house construction market. Its plan is to make Auscrete, which is similar to / competes with Aircrete.
Auscrete appears to be unable to manufacture it's one core product, whereas Aircrete already does so and has a real market.
Based on the low on 08/23/2019 $ASCK will be converting and selling shares at $0.00025 this coming week. That's their market: selling shares, not selling goods.
If anyone is curious, the cost to build the shell of a building using Aircrete is about $9 / square foot.
