Geotechnical Soil Bore TestingGeotechnical testing involves soil boring with an augur drill extracting a soil sample 25’ to 35’ deep which is then sent to a lab where an engineer studies the physical properties of soil.
What is Geotechnical Testing?
Geotechnical testing involves soil boring with an augur drill extracting a soil sample 25’ to 35’ deep which is then sent to a lab where an engineer studies the physical properties of soil and rock to identify possible construction problems and evaluate settlement damage to buildings and structures caused by settlement. Generally there is a 4” by 4” hole left in the front and back yard that can be easily filled or patched leaving little to no impact on the appearance of the landscaping. In some cases, we will replace sod when necessary to restore the appearance of the lawn.
Why consider a Soil Bore Test?
This testing reveals potential weakness or failure of subsurface materials. This information is highly recommend to have before creating foundation designs and other structural plans like installing a swimming pool. However, in reality most residential properties are constructed without such testing as this is often not required by city building departments.
Cost of repair if Problems are found:
Foundation stabilization options can include installing pilings which can cost $1,200 per piling. Pressure grouting and or foam injection for existing structures with cracking or settlement problems is a common repair method. This can often cost anywhere from $10,000 to $50,000 as we have seen on many projects. We have seen foundation repairs performed for as low as $2,000 in more minor cases to as high as $75,000 in our experience in a larger home requiring installation of pilings throughout.
