Brela, 1997:
trench for a waste-water disposal pipe-line. Instead of classic concrete casing, we used pre-fabricated elements. The entire operation took 48 hours to complete, instead of 25 days, as originally planned by the investor.
Dredging a canal in the sand - instead of conventional dredging by a dredger we applied a special pump with a
capacity of 120 m3 of sand per hour: Omiš 2000
