Flowable Fill (CLSM) · Yolo County
Flowable fill — controlled low-strength material (CLSM) — is a self-leveling, self-compacting slurry that replaces compacted backfill. It flows into trenches and voids, sets firm enough to support loads, and can be excavated later if the utility ever needs to come back up.
Volumetric batching is ideal for CLSM: quantities are metered on the spot, so a long trench or an odd-shaped void gets filled without guessing truckloads in advance.
If Dunnigan weather turns on pour day, on-site batching is forgiving: nothing is mixed until conditions and crew are ready, so a pushed start costs patience, not a load of concrete. Odd quantities are normal here — trench lines and curvy forms never take a round number. The meter runs while the pour runs, and the invoice matches the meter.

Utility trench backfill, filling abandoned pipes, tanks, and vaults, and structural void fill. It eliminates compaction in lifts — the material consolidates itself and supports load when set.
Standard CLSM mixes are designed to be excavatable with normal equipment, which is why utilities prefer them over lean concrete for trench work. Tell us the intended use and we will batch the right strength.
A few days' notice books most residential pours; larger or inspected work benefits from more lead time. Same-day dispatch is sometimes possible — it never hurts to call.
