Recyclable and safe anchor bolt protection for the tower foundation of wind turbines
At DAFA, we are passionate about offering innovative and sustainable solutions which seal, absorb, and protect. In our pursuit of constantly becoming better, we develop new solutions and improve existing ones.
Therefore, when a customer requested a new version of our anchor bolt protection solution, it was a natural decision for us to make a thorough analysis of optimization potentials that could lower the environmental impact. This resulted in a solution with better product quality, less waste during the manufacturing process, added safety for workers at the site, and more convenient recycling.
During the casting of wind turbine tower foundations, large anchor bolts need to be protected from concrete so they are not damaged and, in turn, complicate the tower installation. DAFA’s initial solution for protecting these anchor bolts was made of Stratocell, a flexible, lightweight, and cost-effective material. In addition, this universal solution fitted most anchor bolt sizes.
However, our customer, an acknowledged wind turbine manufacturer, requested a new version of anchor bolt protection.
The second version, a PVC sleeve with an extended shaft, was even easier to install at the site, and it ensured even better protection of the anchor bolts during casting.
