How can I ensure proper density around drainage structures?
One of the common failures which can occur on a concrete parking lot is around drainage structures. Inadequate compaction of backfill material around these structures can result in loss of support for the pavement. In lieu of using compacted backfill, an option is to use a controlled density fill material (also known as Controlled Low Strength Material/ CLSM) or flowable fill. This will prevent settlement of the slab. To learn more, click here to setup an in-house workshop for you and your design staff.
