A potential problem with voids under a runway was confirmed after a Boeing 737 dropped through the concrete taxiway at the Mid Delta Regional Airport in Mississippi. It was reported the airplane sustained approximately $1.5 million in damages (OUCH!). Ground penetrating radar was used to map any potential voids near the storm drain which crosses [...]

This started after decades of silence and suffering that Steve House links to exposure to the dangerous herbicide in 1978 when he [...]

Ground Penetrating Radar Soil Suitability Maps

Posted by on October 7, 2010 at 12:28 pm

Ground penetrating radar’s effectiveness is greatly dependent on site-specific soil type. The soil type of a survey area will determine the depth of penetration of the ground penetrating radar signal.  One of the most difficult soil types for GPR equipment to penetrate is wet clay. As an example, where a mid-level frequency GPR system may [...]

Environmental Assessment of a Rattlesnake Habitat

Posted by on June 14, 2010 at 4:28 pm

This is our first blog post and I thought I would start with a unique ground penetrating radar application. Our company was commissioned to conduct an environmental survey to locate a prairie rattlesnake habitat (hibernacula) where an endangered Alberta rattlesnake makes its winter home. The reason it was important to locate this subsurface habitat was to [...]
