Controlled low-strength material for utility trenches, abandoned pipes and tanks, and structural backfill that never needs compaction.
Flowable Fill (CLSM) · Sacramento 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.
Whether it's a weekend homeowner project or a contractor pour on a deadline in North Highlands, the process is identical: confirm the mix with dispatch, stage the site, and pour exactly the yardage the job takes. Repeat contractors get a rhythm going with dispatch — standing windows, familiar mixes, and a call-ahead system that keeps crews placing instead of waiting.
North Highlands is a Sacramento County community of roughly 42,694 residents, about 11 miles from our West Sacramento yard — typically 14–34 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.
No minimum-truckload games — volumetric mixing means we batch on site and you pay for the yardage actually poured. Small North Highlands pours are welcome; see our short-load page.
Tell us what you're pouring and when. We'll bring the mix to your site and meter it by the yard — so every dollar you spend ends up in the forms.
