Controlled low-strength material for utility trenches, abandoned pipes and tanks, and structural backfill that never needs compaction.
Flowable Fill (CLSM) · El Dorado 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.
South Lake Tahoe sits about 87 miles from our yard, and here's why that barely matters: the concrete isn't mixed until the truck is parked at your forms. Distance affects our drive, never your mix quality. Repeat contractors get a rhythm going with the order desk — standing windows, familiar mixes, and a call-ahead system that keeps crews placing instead of waiting.

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.
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.
