Want a quick recap of the work Kissner GC, Inc. has done at Delta Middle School in the last 6 months?  This 1-minute video is annotated to explain the major steps thus far in the building process. 

If you’re curious what base material is, which is mentioned towards the end of the video, read on.  Base material is compacted backfill that goes beneath concrete to ensure that the concrete slab doesn’t shift or move.  The base material is tested and inspected before concrete is poured.  Ultimately, KGCI will place backfill 2 feet deep across the entire interior of the site.
