One of the areas we are trying to solve is a step in a process that requires us to build concrete vaults that are at least 2 tons heavy and required heavy lift machinery, safety protocols and protection. It costs us a good 4 number to build plus numerous hours to manufacture store, transport and lower for use
There are numerous solutions being proposed:
1 Same concrete vault but:
1 . Use of wire mesh and do away with 10 mm rebars, Use of lightweight concrete : with chemicals foamed concrete and lahar pebbles (1/4). + styropor sandwhich
2. Use of plastic virgin plastic: Inca plastic, Quotes being awaited.
3. Use of vaults, using recycled plastic Stefanie will ask from Gentri
For 2 and 3 we ask from waiver from DOH
4 Concrete panels that are manufactured c/o JR but are say only 2 inches thick instead of 3 inches, to be delivered as panels in bullk and numbered bolted in site at the excavation to do away with vault hauler. We need more skilled workers.
