Soil compaction testing and concrete testing requested same day, tester on site after one hour. Travel time was 45 minutes so it took only 15 minutes from the time I ordered the services and when their tester left their shop. Their tester also took a sample for proctor testing same day. He also was at the site next day at 7:00 AM sharp for our compaction testing. Smooth. Super fast! Exceptional quality! The prices are also reasonably low.
