Sugar-Sand Soils and Geotextile Under Pinellas Pavers

A lot of Pinellas County sits on fine, pale sand that looks stable when it is dry and turns into a slurry when a storm saturates it. Crews call it sugar sand. If you drop crushed stone on it with no separation and compact once, the sand works up into the base. The field looks tight at handover and starts to dish six months later.

That is why geotextile belongs under many Pinellas paver jobs. It is not a marketing extra. It is a filter and a separator so the base you paid for stays the base you have.

When geotextile is the right call

• Fine native sand with little fines to bind it

• Low lots that hold water after a two-hour storm

• Driveways that will take trucks, boats, or a heavy SUV

• Repair jobs where the old field settled in a bowl and the subgrade is still pumping

How we use it on a PaverForge job

After the excavation is clean and the subgrade is graded, the fabric goes down flat with overlaps at the seams. Stone is placed on top in thin lifts and compacted so the plate is working the rock, not punching holes in the fabric. Bedding sand stays a bedding layer. It is not used to hide a wavy base.

Geotextile will not save a job that was under-excavated or left without an edge restraint. It will keep a correctly built base from contaminating itself. On coastal and low mainland lots, that difference is the difference between a field that needs a re-level in two years and one that does not.
