Dam Erosion Protection

For over 70 years asphalt has been used to waterproof dams either as a core or as a lining.  When placed as a lining the asphalt also provides protection against wave impacts.
On older UK dams a clay core or blanket within the dam embankment was often used to provide the waterproofing and the dam embankment required additional protection from wave attack.  This was often provided by stone pitching, loose rock, or concrete blocks.
Hesselberg Hydro has worked with dam owners since 1991 to create innovative, cost-effective solutions to upgrade existing erosion protection systems and to provide new erosion protection for dam-raising projects.

Why is maintenance and development of existing dam structures important?
