Proper compacting techniques for sand - Fine Homebuilding

Sep 26, 2005· I am replacing the concrete floor in my 80 year old barn. I removed the old concrete and then removed the clay below it. In some places I removed 3′-4′ of clay. I then put sand back in to replace the clay. I did not compact the sand as I put it in. Our two horses have been compacting the sand for about 4 weeks, one foot (hoof) at a time.
