Local Infill Material for Florida Residence - Coquina Sand
A Florida resident used crushed coquina sand to fill 3" and 2" panels of RutGuard to create a solid foundation within the sub-base layer for both walkway and driveway areas. Paver stones were laid atop the filled cells in the walkway portions. The driveway portion was compacted after the cells were overfilled by 1-2", providing a solid rolling course over the buried geocell panels.
Sand As an Infill
Typically, it is strongly recommended to only use common sands within the sub-base or foundation portion of a project; such as paver stone/flagstone base, patio foundations, building and shed foundations, etc. For this particular application, a local material, called Coquina Sand was used. The particular sand is known for its compaction ability in the sub-base layer and is commonly used in roadway and driveway applications. Unlike typical sands, it contains a mixture of crushed rock and shells in addition to its fines, allowing the material to lock into place and compact.
