GEWI® Soil Nails stabilize Slopes in the Historic Spa Town Solán de Cabras

In 2011, the Mahou San Miguel Group, the market leader in the Spanish beer market with approximately 2,700 employees, bought Spain’s prestigious Solán de Cabras mineral water brand. The bottling plant of the mineral water producer is located in the traditional spa town of Solán de Cabras, approximately 2 ½ hours’ drive east of Madrid.

As part of their growth strategy, the Mahou San Miguel Group decided to remodel the mineral water factory and bottling plant in the historic spa town Solán de Cabras.

In order to protect and preserve the very scenic natural environment around the bottling plant, private passenger traffic towards the spa was separated from the delivery traffic for the bottling plant. The company CRC was therefore awarded the contract for the construction of two separate roads on different levels. Construction work was carried out under strict environmental supervision.

In order to permit the construction of the roads on two different height levels, several retaining walls had to be erected to protect the slopes next to the planned alignments, some of which were permanently tied back using GEWI® Soil Nails.

For the permanent slope stabilization in this area, DSI Construction Spain supplied 258 double corrosion protected (DCP) 25mm Ø GEWI® Soil Nails as well as 385 DCP 32mm Ø GEWI® Soil Nails. DSC supplied the soil nail systems including nuts and anchor plates and also provided the equipment needed for installation.
