Spring 2000

Five city swimming pools in the City of Providence were filled with flowable fill to bring the deep end up to the height of the shallow end.

Approximately 2500 cu yds of flowable fill were used in this application.

This engineered application of flowable fill had initially required a density not greater than the weight of water per cubic foot, 62.5 lbs (+/-1). While this was entirely possible through the use of admixtures, the timing of the year, placement requirements, and most importantly, cost allowed for changes in the initial design requirements. The final flowable mix submitted and approved resulted in over 50% cost of material savings, which ultimately was passed on to the City of Providence. Utilizing a modified standard flowble mix design was the most important factor in maintaining the engineering integrity for all pool locations.
