Scientists have developed permeable pavements to reduce the problems caused by storm and runoff water in urban areas. The project also aims to prepare for the higher volumes of rainfall and more intense storms that can be expected in the future. The pavement solutions developed in the project are well suited for areas with low traffic volume, such as car parks, pavements, courtyards, fields and squares.

The permeable pavement consists of a surfacing layer and sub-surfacing materials with high porosity that can retain water. Other materials, products and structures can also be incorporated, such as drainage and water collection systems, geotextiles and geomembranes.

Water infiltration capacity and winter durability performance was verified for the full service life of the pavement structure, from design to construction and lifetime maintenance. Based on the international experience, the geotechnical structural designs of the pervious layers have been modified and adapted to Finnish requirements.
