Design

Hesselberg Hydro will be pleased to advise on possible asphaltic solutions and give budget costs.

We offers this free design and advice service for problems related to water erosion and landfill lining.

Usually, there is an asphalt alternative to rock, concrete blocks or gabions-the materials commonly selected by engineers.

Consideration of such alternatives at the value planning stage can only be beneficial for client and consultant. And for contractors, a more cost-effective alternative in the tender documents should help win work, or improve margins on work already won.

We commonly provide design and advice for:

• Pattern grouted rock as an alternative to rock revetments
• Open Stone Asphalt revetments as an alternative to concrete blocks or gabion mattresses
• Underwater scour protection
• Construction techniques for asphaltic landfill liners

Details of our expertise in these and many other areas of operation can be found at Applications

Project

Megget Reservoir

The success of our approach is illustrated by our project at Megget Reservoir, Scotland where persistent damage to the rip-rap upstream face was demanding regular maintenance.

• Client decided a permanent solution was needed
• Hesselberg Hydro offered a design using bituminous grout
• Bituminous grouting favoured over other options after a detailed value planning study
• Hesselberg Hydro, in close co-operation with consulting engineers, RH Cuthbertson & Partners, carried out on-site trials and advised on mix designs and installation techniques
• Contract for main works, put out to open tender, was won by Hesselberg Hydro
