Solmax PolyLock profile

Solmax continues its extraordinary growth, this time through expanding the manufacturing capabilities at its state-of-the-art geosynthetics plant in Rechlin, Germany. The line enhancements, recently announced by the company, will immediately benefit the production of PolyLock and Interlock polyethylene (LL/HDPE) profiles. The extruded LL/HDPE concrete embedment strips allow engineers and geosynthetic installers to securely anchor the company’s geomembranes to concrete.

“Our Rechlin plant supplies our clients across Europe, Middle East and Africa,” said Allan Jackson, EMEA Sales Director in a release. “With the addition of production capacity to produce these profiles at our Rechlin, Germany plant, we ensure a ready supply of an enhanced solution to the EMEA market.”

Solmax is the largest geosynthetics manufacturing entity in the world, with an especially strong presence in containment applications such as mining and waste management.


The use of profile materials to support the efficient connection of geomembranes to disparate materials like concrete greatly expands the types of designs and facilities that can utilize geosynthetic lining systems. The cast-in-place mechanical anchor systems from Solmax provide an effective, economical solution for its wide-range of LLDPE and HDPE geomembranes.

Solmax PolyLock is a durable, HDPE profile designed to set and anchor geomembranes to concrete. The product uses T-shaped embedment anchor fingers to create a high-strength mechanical anchor in the concrete, while the exposed LL/HDPE surface allows for the geomembrane to be welded to the PolyLock, thus creating a highly effective barrier termination system.

Solmax Interlocks are used on vertical barrier systems, which are used in environmental and civil applications to contain, exclude, or remove potentially hazardous liquids. Interlocks are permanently attached to the vertical edges of the geomembrane panels and make use of hydrophilic sealants to fill seam and other cavities. This ensures leak-free panel connections.

An example is the Solmax CurtainWall Interlock system, which comprises a reversible HDPE profile designed with multiple sealant chambers.

The profiles are immediately available.

“We are pleased to be able to continue improving our service to our clients in the EMEA region,” Jackson said, “supporting the reliability and longevity of their containment applications to secure their investments and protect the earth.”
