At Schiphol, 35,000 m2 of oil-processing filter fabric (PF90) is laid under the pavement as part of a Breeam excellent certification. This specially designed filter fabric blocks 100% of hydrocarbons, preventing oil and gasoline particles from penetrating the soil. As rainwater seeps into the ground, the contamination is captured in the fabric and then naturally broken down by added microbes. It is easy to apply and ensures that the soil remains clean and the environment is protected.
