Soils Testing & Drilling Service
A quality soils test is of the utmost importance for the homes foundation. Our soils tests, completed by Homestake Engineering, will provide your foundation the right start. Homestake has been conducting soils testing in Colorado since 1985. Included in the process is a subsurface investigation report, and foundation recommendation for your home, detached garage, barn, or addition.
What would happen if your house or this school was built on unstable soils? If part of the soil started sinking, the building might crack or move. Engineers help us make sure that buildings and other structures are built on stable soils, decreasing the risk of building failure due to unstable soil.
Before a restaurant, office tower, house, bridge or any other building is constructed, geotechnical engineers conduct environmental site assessments, which include soil tests, in the areas proposed for development. They examine soil samples to learn about the underground composition of the soils in the area, and make predictions of the long-term effects the soil at the site might have on the walls, foundation, septic system or any other components to the proposed structure. Some soils, such as clays, have a tendency to shrink and swell when their water content changes. This expansive property can put pressure on structure and foundation walls and cause them damage. Other soils are poor at settling or sinking under weight, causing uneven ground. Foundations that are built on these soils are at risk for cracking or bending.
How do you suppose they find out what type of soil is in the area? (Take suggestions from students.) They drill into the ground and look at the layers of Earth in the form of soil cores. A soil core is a vertical view (or soil profile) of everything below ground, contained in a long clear tube. The core tube contains soil that is removed from a hole drilled in the ground, or a borehole. In real life, each soil core is usually only several feet in length. However, the drill rig used to take the soil core can take more than one in the same place. For example, if a company was drilling a 20-ft (6-m) borehole, and each soil core tube was 3-ft (1-m) in length, the drill rig would take about seven soil cores during the drilling.
borehole: A hole drilled in the ground.
borehole log: A method of detailing a soil core profile.
drill rig: Equipment used to make a hole in the ground.
model: (noun) A representation of something, sometimes on a smaller scale. (verb) To simulate, make or construct something to help visualize or learn about something else (such as a machine, structure, process or system), often something that cannot be directly observed or experimented upon.
soil core: Tube containing soil removed from borehole during drilling process.
