Ter Alpin GmbH, Alpincenter Bottrop
Measurements showed that the pillars that propped up the ‘Alpincenter’ indoor skiing centre in Bottrop were subsiding and shifting, to the extent that the centre would have to close within four years. Ter Alpin GmbH contracted Van Boekel GmbH to fill the slope on which the skiing centre had been built to counterbalance the subsiding pillars.
Before we could start work on placing the counterweight, we applied a loamy seal, topped with drainage sand. To collect water from the fill, we also built a storm catch basin, from which water is drained via the sewage system.
