Abstract

The construction includes a substrate or other surface layer and also a filter layer having a pipe network (2,3). The pipe network (2,3) comprises numerous perforated multi-purpose pipes (3) to dry the field and to lead air through the field. - In the filter layer (4), the proportion of fine material or material having a granular size of less than 0.06 mm is less than 5 percent, most advantageously the proportion is less than 1 percent, so that the filter layer is highly permeable to air, and the substrate includes so much fine material that is less permeable to air.
