Wind turbines have weak points which need to be waterproofed to ensure long-term safety. These include (expansion) joints and concrete plinths. Even though waterproof concrete is utilised, joints can be subject to extreme stress caused by freeze/thaw cycles. Due to harsh weather conditions the concrete may show cracks and spalling. Penetrating moisture poses a real threat to expensive technology.
Discourse with operators has shown that the Kemper System must “be completely applied to the plinth surface – from the painted steel pylon and the expansion joints right down to the actual body of the foundation”. (Depending on the type of wind turbine, the plinth is located in the foundation area or six to eight metres above the ground.) Based on a component service life of 20 years, the Kemperol waterproofing system satisfies the following demands:
KEMPEROL is a tested and marked building product. It is approved according to ETAG 005 and has the following classifications:
Due to its liquid application Kemperol can be adapted to any substrate. This means it is ideally suited for utilisation on round plinths. This waterproofing system already provides long-term protection to hundreds of wind turbines throughout Europe.
