Stabilization of an Excavation using DYWI® Drill Hollow Bar Anchors: New Residential Building at the Dietl Brewery Site in Straubing

In Straubing, a new residential and office building is being built on the site of the former Dietl Brewery. The new building is located at a 5 minutes’ walk from Straubing’s central square and includes one commercial unit as well as 35 apartments.

The approx. 9m deep and 100m long excavation was temporarily stabilized for the project. Some areas of the excavation were stabilized using self-drilling DYWI® Drill Hollow Bar Anchors and shotcrete.

DYWIDAG-Systems International Germany supplied 1,700m of R32 DYWI® Drill Hollow Bar Anchors as well as 300m of R38 DYWI® Drill Hollow Bar Anchors for this purpose.

To stabilize an existing building, 22 75mm Ø bored piles had to be installed at center distances from 1.75 to 2.5m in some parts of the excavation. These were stabilized in 3 layers using 775m of 2-5 strand temporary DYWIDAG Strand Anchors. DSI supported the stressing work on site.
