Forensic Geotechnical Investigations for Distressed Structures

Site Evaluations – Hetherington Engineering, Inc. can perform an evaluation of your property, which will typically include a detailed site inspection with photographic documentation of distress, researching documents, either in our own library or at the local building department,  and a manometer (floor level) survey to determine whether there are indications that adverse geotechnical conditions may be contributing to the distress and provide guidance in whether a detailed investigation is necessary.

Distress Investigations – Foundation distress can be caused by a wide variety of factors, and determining the exact case and nature of any ground movement is essential to providing the proper repair concept. Hetherington Engineering, Inc works with a wide variety of subcontractors to enable us to investigate problems such as foundation movement caused by heave and shrinkage of expansive soils, settlement of structures due to poorly compacted fills underlying the structure and movement related to slope movement and landslides.

 

Engineering Analysis and Design of Foundation Repairs – Determination of the type and nature of ground movement that has caused distress to your structure and its foundations is the first step in providing a long-term, cost-effective solution. With over 100-years of combined engineering and geologic experience, the staff at Hetherington Engineering, Inc. can provide innovative solutions to real world problems experienced by homeowners and property owners.
