Concrete Canvas remediation advantages

• Speed of installation• Ease of installation• Installation in inaccessible/ remote locations

• No need for removal of existing infrastructure• Thinness of CC doesn’t change the load capacity or flow characteristics of a canal• Low manning’s friction coefficient• Canal operator’s familiarity with concrete as a solution• Visual aspect of CC compared to patching solutions

Concrete remediation potential is massive

Half of distributor country overviews mentioned concrete remediation jobs or potential jobs:

•Australia 250kms canals• Israel 130kms canals • South Africa 22 kms canals

European markets

France• Bar hydroelectric plant 7kms - 36,000sqm• Societe Canals de Provence 68kms - 220,000sqm initially, EUR 6,000,000 over 4 years. Potential 1,000,000sqm in total• Canal Lille, North of France. 26 kms

TurkeyOver 100 hydroelectric plants constructed in recent years, many already exhibiting big problems with cracking in the canals
