Construction Work for Generations.

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, canals, landfills and dams, various repairs are also part of our specialist department’s range of services.

We can renew surface seals in need of repair on both a small and large scale. The old asphalt liner is removed using milling machines that can also operate on embankments with slopes up to 1:1.5 thanks to special winch cars. The new asphalt liner is installed following the subsequent cleaning and preparation of the surfaces. The repair work can also be carried out above water, i.e. when there is water below the surfaces to be repaired. Suitable barriers prevent the materials or any pollutants from entering the water.
