Canal bank revetments

The bank revetments are stone covers laid out on both sides of the canal. During the 18th and early 19th centuries, these were built to keep the canal banks intact and protect against various types of erosion from waves and other wear along the water lines. These are now wearing out because of larger waves caused by larger boats and propellers, things that didn’t exist when the canals were built and all boats were pulled by horses and oxen.

These revetments consist of a shelf, strengthened with pins and covered with stone materials in two separate layers. The inner layer consists of crushed rock with a diameter of 0-200 mm and is approximately 200 mm thick. The outer layer is twice as thick, 500 mm, and consists of crushed rock with a diameter of 200-450 mm. The pins prevent the rock from collapsing into the canal and obstructing the waterway.
