Controlled low-strength material for utility trenches, abandoned pipes and tanks, and structural backfill that never needs compaction.
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.
For a Yolo County community like Knights Landing, flexibility matters: crews juggle inspections, weather windows, and finisher schedules. Because batching happens on site, a shifted start time doesn't spoil a load — the concrete isn't made until you're ready for it. Tight access — backyards, narrow drives, sloped lots — is a conversation, not a dealbreaker. Tell dispatch what the approach looks like and we will plan chute reach and staging before pour day.
Knights Landing is a Yolo County community of roughly 995 residents, about 18 miles from our West Sacramento yard — typically 27–47 minutes for a mixer to reach, traffic willing.

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.
