Geophysical Survey Locates Voids Beneath Concrete Floor

portfolio typeCase HistoriesPosted on

A local construction company discovered voids beneath a concrete building floor after the floor collapsed in several locations. To determine the extent of void development beneath the concrete floor, Mundell personnel completed a geophysical survey using a ground penetrating radar system (GPR), with a 1000-megahertz antenna .The results of the GPR survey indicated several void areas between the bottom of the concrete floor and the underlying fill materials on the order of 0.1 and 0.4 feet in thickness, were linked to leaking sewer pipes nearby……Read More »

Geophysical Survey Locates Buried Conductive Objects at Industrial Landfill Site

portfolio typeCase HistoriesPosted on

A records search and personal interviews at an aluminum industrial facility had reportedly indicated that landfill materials (in particular, carbon cathodes) had been buried in an approximately 53-acre area behind the facility. Mundell personnel completed a GPS controlled EM conductivity survey of the site, and the results indicated several large areas of highly conductive materials, which when excavated, revealed significant accumulations of spent buried carbon material, including several virgin carbon cathodes and anodes, metallic objects, and general construction debris……Read More »

Refraction Microtremor as a Tool to Map Bedrock Fractures

portfolio typeCase HistoriesPosted on

Mundell was retained by an environmental consultant to use the Refraction Microtremor technique (a passive seismic method) to map out the subsurface geology beneath an active industrial site, in an attempt to locate any possible bedrock depressions and fracture zones which could be acting as preferential pathways for soil and groundwater impacts……Read More »

Ground Penetrating Radar Analysis of a Concrete Spillway

portfolio typeCase HistoriesPosted on

Mundell conducted a non-invasive, high-resolution, ground penetrating radar (GPR) survey of a concrete spillway to map the location of potential voids below the concrete after a significant outflow of water was detected from beneath the base of the spillway. The GPR investigation revealed the source of the outflow from beneath the spillway, and verified that the sub-base materials were sound. …..Read More »

Geothermal System Design using Geophysics

portfolio typeCase HistoriesPosted on

As part of the preliminary subsurface evaluation for the Ball State University Geothermal project, Mundell conducted surface two-dimensional resistivity testing and downhole geophysical logging to map the variation in geologic and hydrogeologic conditions beneath the site. This data proved extremely useful in the bidding process for the well installations, and for establishing and drilling specifications for the geothermal wells. …..Read More »

Give Thanks to Mother Earth

Planning a relaxing Thanksgiving with family and friends? Thank Mother Earth this week by creating an environmentally friendly day. Here are some tips for a green Thanksgiving.

  • Shop your pantry before you take a trip to the store. What you can make with what you already have on hand?
  • Create a leftover plan ahead of time so your goodies don’t go to waste
  • Decrease energy usage by turning off your TV and talking a walk or playing some board games
  • Create your own decorations (dried leaf place cards, painted gourds, etc)
