SOILS REPORT
The Geotechnical Soil Report, explains about the load bearing capacity of soil and rock, and the plasticity of different soils or clays. The report is intended to define the subsurface conditions and may provide geotechnical conclusions and recommendations for the foundation repair method to be used. Sometimes a Geotechnical Soil Report is necessary before a foundation repair can be performed or even quoted. These reports can only be prepared by a licensed geotechnical engineer and cost cost in the range of $500 to $3,500. You local foundation repair contractor should help you local a geotechnical engineer in your area. Click here to contact a local foundation repair contractor.
Generally the reports will contain some or all of the following information:
- A review of the geologic history and history of prior excavation and fills.
- A field reconnaissance of the site and vicinity.
- Scope of work done, investigative methods, sampling methods, logs of borings or test pits, elevations of borings or test pits for reference of materials and samples to finished grade or footing elevations, identify elevations.
- Location of all samples taken, surface and subsurface.
- Groundwater conditions and potential future natural and artificial seepage effects.
- Unified Soil Classifications of Materials.
- Material competency and strength of existing soils.
- Pertinent engineering geologic attributes (clayey, weak, loose, alignments, fissility, planar boundaries, pervious or water-bearing parts, susceptibility to mass wasting, erosion, piping, or compressibility).
- Bearing capacity and/or shear strength of sample areas.
- Consolidation or settlement potential.
- Expansion potential.
The National Cooperative Soil Survey identifies and maps over 20,000 different kinds of soil in the United States. Most soils are given a name, which generally comes from the locale where the soil was first mapped. Named soils are referred to as soil series. Soil survey reports include the soil survey maps and the names and descriptions of the soils in a report area.
