Functioning and efficient drainage of traffic routes is essential both to protect the infrastructure and to minimize environmental pollution. In rainy weather, roads with heavy traffic can release large quantities of pollutants into the groundwater or surface water.
Drainage pipes play a central role here by systematically draining the wastewater.
If the sewer system is overloaded during heavy rainfall, the water can be forced back into the road surface via the drainage pipes. This returning water softens the subsoil, which jeopardizes the stability of the road surface. Softened road substructures lose their load-bearing capacity, which leads to deformations, cracks and other damage. This can not only affect the safety of road users, but can also result in expensive repairs. In addition to structural damage, the dirt particles from the sewage can settle in the road bed and pollute the surrounding soil.
This is where the Stop Silent® SL13 backflow flap comes in: It effectively prevents water or wastewater from being forced into the drainage system in the event of backwater. This not only protects the substructure of the roadway from softening, but also protects the environment from potential pollution. The use of Stop Silent® SL13 helps to ensure the long-term stability and safety of traffic routes, even under extreme weather conditions.
