Inspections
Bander Smith, LLC has highly trained team of inspectors including OSHA and ADC commercial divers.

Inspections completed by Bander Smith come with a full report including pictures, recommendations, and as-built drawings. We also provide video and photographs to document the inspection and provide a baseline for further observations.
Our highly experienced crews have been on hundreds of dams, and know what to look for.
Sliplines
Sliplining is a process of lining an existing pipe with a smaller pipe and grouting the annular space.
This is great option for aging dams with Corrugated Metal Pipes, that doesn't involve draining the lake and excavating the entire embankment.
We complete slipline projects with HDPE and steel pipe, and can provide options for new drain valves on existing structures.
