Dedicated to advancing the use of fabricated geomembranes through education, research, and technology transfer.

WHY?
Factory fabrication reduces field welding, reduces installation time and costs, allows modular construction and provides consistent seam and liner quality.

PROJECT SPOTLIGHT

Chambers Dam Reservoir Remediation Phase II

GEOMEMBRANE APPLICATION: 
Raw Water Storage
MATERIALS USED:
16 oz. Geotextile and 45 mil Black/Tan scrim reinforced LLDPE Geomembrane
MEMBER COMPANY: 
Raven CLI Construction
PROJECT DESCRIPTION

Phase II of the Chambers Reservoir project consisted of upgrading an existing earthen raw water storage reservoir and fabricating and installing a 45 Mil Black / Tan - N45BT (Scrim reinforced LLDPE.) with a 16oz. geotextile underlayment for protection. Furthermore, 6,600 LF of black safety ladders were installed in various spots around the perimeter to ensure safety while accessing or egressing the reservoir.

LESSONS LEARNED 

The use of the scrim reinforced LLDPE greatly reduced slope creep & wrinkles at the toe of slope that is common for reservoirs of this size. Furthermore, the use of intermittent berms across the floor prevented erosion and subgrade issues from rain events throughout the installation process.

HOW THE USE OF FABRICATION IMPROVED THIS PROJECT

Large prefabricated panels gave Raven the ability to maximize production and shorten the overall installation time greatly - something that was crucial to beat owner deadlines and the fall / winter weather common for Colorado.
