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.
We've built our Sacramento County routes around communities like Wilton — morning staging, clear dispatch windows, and a call-ahead so your crew isn't standing around waiting on material. 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.
Wilton is a Sacramento County community of roughly 5,363 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.
No minimum-truckload games — volumetric mixing means we batch on site and you pay for the yardage actually poured. Small Wilton pours are welcome; see our short-load page.
Formed and staked forms, clear truck access, someone authorized on site, and a washout area. Our Before You Order guide walks through all of it.
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.
