Pond Free Block

Use Pond Free Blocks to create high-capacity water storage for your pond free applications.  Blocks have 97% void space, compared to 20% for gravel, allowing for 5x more water in a smaller space (30 gallons each).  Strong enough to support pavers, gravel, and other landscaping (additional inserts may be added for extra heavy loads). Quick and easy to assemble, reduces volume of rocks needed for fill, and ensurs plenty of water is available for the pump.  Easier to clean and less likely to clog compared to gravel filled basins.
