We Pump Flowable Fills and Controlled Low Strength Materials

Controlled Low Strength Materials (CLSM) are highly viscous slurries that contain cement, fly ash and admixtures that help flowability and pumpability.

Great for trench fill, CLSM provide a consistency that is 100% compacted after set time, unshrinkable, and consolidate around pipes and utilities.

With the ability to control the density and strength of the CLSM by adjusting the mix design, optimal p.s.i., as per job requirement can be achieved. Material strengths from 50psi up to 1200psi are defined as CLSM. Anything above 1200psi is defined as a grout or concrete. – ACI
