Flowable Fill Project

Flowable fill materials are primarily used as a backfill in lieu of compacted earth in below grade applications such as utility trenches, where low strength and ease of placement are required. This mixture is capable of filling all voids in irregular excavations and hard to reach places (such as under and around pipes), is self-leveling, and hardens in a matter of a few hours without the need for compaction in layers. Flowable fill is typically placed using conventional ready-mix concrete trucks. In many cases, these materials are designed so that they are comparable in strength to the surrounding soil after hardening, making excavation at a later time possible.
