Stratum water is dammed to a water or low water-permeable layer of soil surface water . The water-retaining soil layer prevents the water from seeping into deeper layers. It is also sometimes referred to as floating groundwater .
Influence on structures
Stratified water mostly lies in higher soil layers and is therefore often more dangerous for structures than the groundwater, which is mostly in deeper layers. Remedial measures against stratified water are water-impermeable structures ( black tub , white tub ), drainage or similar.
In order to lower backwater and stratified water during the construction phase, a permit under water law is required. The same applies to the permanent introduction of drainage water into the drainage system or into a receiving water .
