The Diakoniehaus in Lehnin (Brandenburg, Germany) is founded mainly on peat and soils with very low bearing capacity. All access roads faced many deformations due to unstable foundation soil. The reconstruction of the roads was inevitable to assure the safe drive of ambulances to the local elderly hospice. The designer looked for a product that could withstand the load pressures from the constant ambulance traffic and help extend the lifespan of the newly paved road, minimizing the damage associated with the truck traffic, such as cracking and rutting.
