In landfills in particular, it is absolutely essential that the sealing layer is impermeable to liquids. In addition to water, landfills also contain liquids or dissolved materials that are environmentally harmful and could pollute the groundwater. The bituminous seals from WALO are impervious, durable and suitable for particularly polluted materials. Consequently, no further measures are needed to protect the bituminous sealing layer. In addition, they are extremely resistant to ageing and flexibly absorb settlements and deformations of the subsurface.
