Rapid set flowable fill or RSFF is a rapid-setting flowable fill (CLSM) that is a self-leveling, self-compacting alternative to compacted backfill that is delivered to site by volumetric mixer trucks. This product is used in high traffic areas that require a fast turnaround time. When placed to grade RSFF will allow traffic to be opened in one hour, and asphalt to be placed in two. The best results for RSFF is not to disturb the surface for the allocated time, which includes foot traffic, water, machinery/vehicles and or anything that disturbs the surface which can result in a delay of set time.
Conventional Flowable fill or CFF is a low strength (CLSM) flowable fill that is self- leveling, self-compacting alternative to compacted backfill that is delivered to site by volumetric mixer trucks. This product has the same characteristics as the RSFF but with set times of 24 to 36 hours. This product is used for applications that do not require a rapid set material, but if disturbed can impede set time.
