Belzona Seals Wind Turbine Tower Base Against Water Ingress

KHIA ID: 7500
Industry: Power (POWR)
Application: WPA-Wall Problem Areas (WPA)
Substrate: Concrete and Metal
Customer Location: Wind Farm, West Texas, USA
Application Date: Summer 2016

3111 (Flexible Membrane)

3911 (PSC Surface Conditioner)

Problem: Rain water and moisture seeps into the ground and into the wind turbine structure through the base around the tower structure. This over time affects the concrete base and propagates cracks and corrosion at the base of the tower. In this case the current coating failed due to UV degredation leading to delamination from the concrete surface.
