WALO has played a pioneering role in the field of bituminous asphalt seals for over 75 years with its various services in Switzerland and worldwide. Apart from sealing reservoirs, dams and landfills, canals are also part of our specialist department’s range of services.
WALO offers the bituminous sealing of newly built canals as well as repairs to existing canals. In newly built canals, the asphalt liner is applied directly after the earthworks. With repairs, the old asphalt liner is initially removed with a milling machine and then asphalted or asphalted directly on the existing subsurface (e.g. concrete) depending on the type of seal in place. With the help of the canal paver designed by WALO, horizontal application is even possible in curves along the entire length of the canal embankment. Slopes of up to 1:1.25 on the canal embankment are possible here. As seen in reservoirs, waterproof connections to the inlet structures etc. are also realised by special joint constructions with expansion elements.
