The shallow drilled braced monument (SDBM) consists of 4-5 1"-diameter stainless steel legs in a tripod configuration epoxied into bedrock up to depths of about 5-6 feet. The legs are welded together at the top. Use the SDBM at locations where there is bedrock at or within 0.5m of the surface. Ideal bedrock is fresh or only slightly weathered, and minimally fractured/jointed. If extensive weathering and/or fracturing occur too deep, the bedrock is not suitable for this monument. The SDBM is used throughout the PANGA, BARGEN, and PBO networks.


Site NAMA in Saudi Arabia.
