We offer accessories so you can make a certan stone size weight either lighter or heavier than just a concrete stone. You will see weight guidelines with both foam and lead added. The foam we use in the form of balls are manufactured from high grade marine foam so it will not break down and will continue to hold up in the stone. If you would like a custom foam insert made please let us know. We use lead as a weight comparison because you can use more concrete in the mix increasing the strength of the stone. You may purchase lead ingots from many plumbing suppliers also. We always suggest that if you use an insert or add anything into the stone it is best to add our Concrete Strengthening Fibers to the mix for added crack resistance strength. You may view the Density Comparisons of Heavy Materials list at the bottom of the page to see different weight comparisons.
