Installation of the CARPI system on dams achieves the following: Continuous waterproofing of the upstream dam face, including expansion and construction joints and cracks; A new continuous face drainage system; A barrier to water infiltration in the event of formation of new cracks; Reduction of uplift; Dehydration of the dam body

The installation of the watertight perimeter anchorage is one of the most critical aspects of the system. The greatest care is taken to ensure absolute watertight integrity especially at joints or fissured zones, where water could by-pass the system and infiltrate behind the liner.

The CARPI system impermeable water barrier consists of an exposed flexible synthetic geocomposite (impervious geomembrane + anti-puncture geotextile). Linear anchorage of the geocomposite to the upstream face of the dam is made by mating pair of stainless steel vertical patented profiles.

Dams, like other structures, naturally deteriorate over time. Deterioration opens the way for leakage, which in turn accelerates the deterioration process. Even when structural safety is not threatened, there is an economic loss and negative public opinion perception.

The company has pioneered new installation techniques that now are patented systems, while continuously introducing to the market new products of higher performance. Begin your journey in sustainable hydropower.

Nov 12, 2024 · Board authorize EWEB’s General Manager Frank Lawson to approve a contract with Carpi USA up to $3,000,000 for design and construction services related to the installation of a new geomembrane liner at the Walterville Forebay. Since the forebay leak developed in Q1 of 2024, staff were able to add $3.6 million for an emergent Type 2 pro ject

while the Sibelon geocomposite liner provides its water tightness, which reduces the requirements for dam body material and interlayer joints. The geocomposite liner, developed by Carpi Tech SA of Switzerland, is composed of a homogenous polyvinyl

Jul 19, 2024 · Whether it is a landfill liner system, pond liner or canal liner, Carpi geomembranes are critical to attaining environmental standards and minimizing risk exposure. These are unsung heroes of environmental protection who work tirelessly to save our ecosystems.

Carpi's patented external water stop, with a highly deformable watertight geomembrane supported by appropriate geosynthetics, resists multiaxial movements of contiguous blocks and large differential movements at the deformable body/rigid concrete appurtenance interface.
