Tlieses borings were advanced approximately 5 feet below land surface. The house founded at depth ranged between 12 and 15 inches. Boring locations are presented in the Attachment. 3.1.2 HAND AUGER BORINGS 'I�vo test pits were excavated on July 3, 2015 to determine the foundation type and depth of embedment.The test pits indicate the footer was embedded less than 10 inches. i 3.1.3 GROUNDWATER I The groundwater table was not detected within a depth of 5 feet below ground surface. . � • . � . � . . � The observed damage on all the exterior walls is consistent with differential movement of the foundation due to lack of support from underlying soils. SGT was requested by the homeowner to provide underpinning piers for foundation stabilization around the � structure. The underpinnin iers extend the de th of the foundation, so that it is I g P i P supported on more stable soil. Underpinning can be used to stabilize the structure but will ' not deal with any deep soil conditions nor provide a remediation for the soil underneath the residence. . � � • __l��_�—�_.�._..___�_a_.�____e_� �6.1_.G E�N�:E,RA.L , �� ____�_.,�.�_._._..�_..�.��._ ' _ � a.. `.__4 _ � �~_ � ' �� � r` � ` _.�w'- - �M�___� This investigation report of field exploration,sampling,testing, data evaluation,and engineering consultation services has been prepared for the exclusive use by Southeast Property Acquisitions LLC Property in accordance with general accepted geo-forensic engineering methods.
