Reliable waterproofing for continuous energy storage 

Pumped storage schemes play a key role in storing energy generated by renewable sources such as wind and solar. Reliable waterproofing is essential to maintain safety, efficiency, availability and continuous operation of these facilities by preventing water losses and supporting the performance of their reservoirs. 

Carpi’s SIBELON® geomembrane systems provide engineered waterproofing solutions for pumped storage schemes, designed to withstand demanding operating conditions including rapid water flow, extreme wind conditions, high temperatures and aggressive UV exposure. 

Solutions customised for the structure

Waterproofing across pumped storage infrastructure 

Pumped storage schemes rely on multiple hydraulic structures working together to store and transfer water. Carpi’s SIBELON® geomembrane systems can provide waterproofing for different structures within the scheme, helping maintain water containmentand support continuous operation. 

Depending on the project configuration, SIBELON® technology can be applied to: 

Waterproofing solutions adapted to new dam structures within pumped storage schemes.

Impermeable geomembrane systems designed to prevent leakage and maintain water containment.

Project-specific applications where reliable waterproofing is required to maintain the efficiency and availability of the scheme, such as headrace and tailrace canals and tunnels, pressure tunnels and shafts.

Solutions customised for the structure

In new reservoirs and dams, SIBELON® geomembranes can be installed on very steep slopes, allowing increased water storage capacity, and withstanding settlements. Shorter installation times allow earlier power generation.
