A. It is a flowable mixture which contains cement, sand, flyash, water, and/or air and/or foam admixtures. Not all these item will be in every mix. Each mix is designed, batched, and its flowability adjusted by the Ready Mix Supplier for the needs of the specific use.

A. It is mixed and delivered to the job site in ready mix trucks, precisely batched from a Ready Mix plant.

A. Yes, it can be designed to pump through a regular concrete pump, a mud jack pump, or grout pump by the proper use of air, water, and/or flyash.

A. The mixes can be designed for strengths from excavatable 50 psi - 150 psi in one year up to 1500 psi in 28 days.

A. The general answer is NO. However, there are some present uses of materials which currently call for low strength concrete in which it could be used.

A. It is a substitute for compacted gravel. It has many qualities superior to compacted gravel such as: no testing, uniformity, known strength in place, higher bearing capacities, less permeable, more stable, sets under water, no equipment or labor.

A. It is an environmentally safe material that can be disposed of as regular construction material. After it has been excavated it loses its flowability and does not act as a compacted material.

A. Yes, it can even be placed into a hole full of water and it will set up properly with the desired compaction.

A. Yes, in winter it may be heated, and thus be lump free; this is instead of regular gravel materials which usually are full of frost and lumps in winter. Afterpouring, it is best to protect the Flowable Fill with hay or blankets in cold weather.

A. Since mixes contain a lot of water which must be pushed out by the settling of heavier materials, no air fly ash mixes take 90+% of their settlement in the first 1.5 to 2 hours, with minimal settlement thereafter. The high air (25 - 30%) mixeshave minimal settlement.
