McMahon & Mann served as the geotechnical engineering consultant to TVGA Consultants to
complete seepage analyses for the rehabilitation of Lock E8 on the New York State
Barge Canal System. The Canal Corporation had experienced an unstable floor and
water seepage through cracks in the floor in Lock E8 when it dewatered it for various
maintenance activities. It engaged TVGA Consultants to explore the causes for this and
to design other improvements to the lock.

McMahon & Mann reviewed data from test borings previously completed for the lock and monitored
additional borings that were made to measure the thickness of the sand and gravel
deposit surrounding the lock foundation. We measured properties of soil samples
from the borings and measured the permeability of the soil with tests in the boreholes.
We analyzed the subsurface conditions and recommended constructing a seepage
barrier around the lock to cut off ground water flow. This would enable the Canal Corp.
