A filling of the working space around the building with the existing excavated material, provided it contains cohesive elements is not allowed.
The cohesive soil is not able to guarantee a flow of leachate. It may therefore come to the impoundment of water. This in turn may result in the load case for the changes the seal was originally planned.
standard is shown that the filling of room, and the preparation of the drainage layer and the packaging of Perforated drainage pipe with a filter made of mixed sand-gravel (grading curve B32 or A8). So it is often more meaningful and real, especially in cases where cohesive soil exists, the cover of the drainage layer with a coarse gravel or crushed stone (this is in the base area around the house out eaves strip then simultaneously splash guard and separated humic acid soil from the plaster and the moist air from the Erdzone zone) run. It also avoided the surface water on basement windows or skylights penetrate.
The light wells deeper basement windows should be well connected to the land drainage. Such material, which in Area of \u200b\u200bthe grading curve for frost protection in road gravel lies can be regarded as fixed filter, usually against the upcoming soils and also to the up to 1.2 mm wide slots of the land drainage.
is seen from this perspective that is necessary for a cohesive soil stone pack installed as drainage layer. It is important to ensure that the drainage layer is prevented by a filter paper before einschlämmen of soil in the filter layer, unless the built-in layer is so thick that can build up a natural filter.
