InnovoGeo Engineering was contacted by the owner of a small, unregulated pond having a history of low water levels, especially during dry seasons.  The owner had suspected seepage through the pond embankment was causing the low water levels, and had attempted several methods of reducing the seepage to acceptable levels.  As the initial attempts had not proven successful, the owner began considering more substantial repairs. 

InnovoGeo performed two seismic cone penetration (sCPTu) soundings along the top of the embankment with the primary goal of characterizing embankment materials, depth, and strength, identifying depth to phreatic surface and any potential seepage zones, and estimating embankment foundation natural soil properties for potential excavation.

Review of the sCPTu logs collected provided critical insights into sandy residual soil layers beneath the embankment, distribution of pore pressures within the embankment and foundation, and potential excavation difficulty of the foundation materials.

Despite the intense heat and humidity, InnovoGeo’s Pagani rig, Vertek CPT equipment, and crew performed flawlessly. This provided an excellent opportunity to verify equipment reliability and operational performance under stress, and we’re proud to report a seamless investigation from start to finish.
 
Notably, the site remained virtually undisturbed following testing – a results of the rig’s lightweight design and compact footprint.
