HomeMy WebLinkAboutProduct Approval SoilClassification . Ground anchors are designed for different soil classifications: longer models for loose soils, shorter models for harder soils. Prior to installing any ground anchor model,the soil must be tested (with a Soil Test Probe)in order to match approved ground anchor model with site soil class. WARNING: Before ground anchor installation, determine that the anchor locations around home will not be close to any underground electrical cables,water lines or sewer piping. Failure to determine the location of electrical cables may result in serious personal injury. Soil Test Probe The Soil Test Probe is used to determine the soil conditions below the surface near the anchor's helix.Using the Soil Test Probe will ensure maximum anchor holding strength by indicating the proper anchor model for each soil condition. Using the chart provided,a probe reading can be converted to the recommended anchor for every soil condition. Instructions 1. Place probe tip into ground where you intend to place the anchor.Using a 15/16"hex socket with a ratchet or breaker bar, rotate the probe in a clockwise direction.(An electric drive machine with an adaptor head may also be used) 2. Drive(rotate)the torque probe into the soil until reaching a depth equal to the length of the,anchor being installed. 3. To determine the soil classification: • Place wrench adaptor onto torque wrench. • Insert hex portion of wrench adaptor onto the earth probe. • Support probe shaft with one hand,while rotating probe steadily with the wrench.(Do not exceed 600 in.lbs.) • Read the torque wrench while rotating probe clockwise. • Use the soil classification chart to cross reference probe readings.Color codes match those printed on Tie Down's torque probe. 4. If probe reading does not match the anchor for that depth,rotate probe to next anchor depth and check reading. Continue until reading on probe matches anchor length for depth of reading. 5. To remove probe,use wrench or electric drive machine in reverse(counter clockwise). Soil Test Value Soil Class (in. lbs.) Description 600 in. lbs. 1 N/A Sound hard rock.
