(May take a few hours to drain after a heavy rain, but I don't really know, I don't go down there then, everything's wet then anyway). In case of vacuum consolidation, if PVDs are fully penetrated into a two-way drainage deposit, the vacuum pressure will leak through the bottom drainage boundary and cannot achieve a desired consolidation effect. On firm non-cohesive subsoils and rocks such as sand, gravel and sound rock beds which are near the surface, under vegetable top soil and are well drained or dry it is satisfactory to lay the concrete oversite directly on a bed of hardcore or broken rock rubble as there is little likelihood of any appreciable amount of moisture rising and being absorbed by the concrete. Design Certification. 1406 Pump Drainage a) General Drainage pumping plants remove excess surface or ground water where it is impossible or economically infeasible to obtain gravity outlets for drainage. To drain the incoming flow - water intakes must be made and if necessary the deep drainage of the subsoil. It's very common that the design and investigation of subsoil drainage systems are uncertain processes. During rain or irrigation, the fields become wet.
