The customer's challenge
Increased water flow and risk of erosion damage
The redevelopment of the Slussen area in Stockholm has been ongoing for some time. Tecomatic is working on erosion protection in several parts of the area and in Mälardalen. One of the reasons for rebuilding Slussen is that the water level, and therefore the risk of flooding, is too high.
The water level in Lake Mälaren is regulated by canals and sluices at several locations in Stockholm and Södertälje. In Slussen, two large drainage canals with two drainage hatches will be built to allow larger amounts of water to be discharged from Lake Mälaren to the Baltic Sea, which means that almost five times as much water will be able to be discharged from Lake Mälaren to the Salt Lake. This means that the risk of flooding is drastically reduced throughout the Mälardalen valley, but also that the high water flow creates erosion, which can destroy the bottom, bridge supports, quays and foundations and pollute the water.
