Abstract:
The undulating walls at the entry hall of the Museum of History of Polish Jews in Warsaw, Poland, were constructed using a stay-in-place form and the dry-mix shotcrete process. To avoid cracking of the walls, a support system was designed to distribute and disperse stresses from the anchorage points into the wall sections. To maintain a uniform thickness of shotcrete and delineate the outer surface, specially designed polymers strips were embedded in expansion and control joints. The strips also enabled installation of plastic sheets to prevent moisture loss and provided protection against shotcrete overspray during construction of adjacent elements.
