LEONHARD WEISS has long-term experience in the construction of waste facilities, storage areas, sediment ponds and leachate systems, and the closure of landfills.
In 2002, we subcontracted earthwork of the Tallinn Jõelähtme landfill site and with AS Aspi and Eesti Ehitus, the closure work of the Sillamäe waste facility. We have completed the following projects: Closure of Järvakandi Tupiku landfill in 2003 for OÜ Järvakandi Kommunaal; closure of industrial waste landfills in Balti and Eesti Power Plant in 2004 for Narva Elektrijaamad AS; construction of the composting fields of Vaivara hazardous waste treatment centre with sediment pond in 2008 for AS EcoPro; intermediate covering of Vaivara hazardous waste treatment centre IV honeycomb composite in 2015 for AS EcoPro.
We built the first sediment pond of a waste facility in 2008 at Vaivara hazardous waste treatment centre with composite squares. In addition, we have carried out construction work on the Kiviõli Waste Recovery Centre's leachate system in 2014-2015 for AS EcoPro.
