Quarter-acre lots and no HOA make Torino, Sandpiper, Southbend and the older GDC sections the boat-and-shed capital of the Treasure Coast, and the newer communities all want a generator pad after the last hurricane season. These are small pours, but the sand and the water table make them easy to get wrong: a shed slab poured at grade sits in an inch of water every summer; a boat pad on uncompacted fill ruts under the trailer tires; a generator pad that isn't level throws the unit out of spec.
We build the pad up: fill compacted in lifts so the top of the slab sits above the wet-season water line, a thickened edge, fiber mix with steel, and for boat and RV pads five to six inches with the tires' path in mind. Anchor bolts or J-bolts set for the shed manufacturer's template; the generator pad sized and leveled to the installer's spec with conduit sleeves where they want them. Sheds over the city's size threshold and anything with electrical are permitted; we handle the site plan and the permit under our license.

Questions we get about slabs, pads & sheds
Do I need a permit for a shed slab in Port St. Lucie?
For sheds over the city's size threshold, anything with electrical, and anything that changes drainage, yes — the slab is inspected as part of the shed permit. Small sheds without utilities often don't need one. We check your address and tell you which.
Can I park my boat on the side of my house?
In Torino, Sandpiper, Southbend and most non-HOA GDC lots, yes, on a proper pad behind the front setback. HOA communities like Tradition and St. Lucie West restrict it. The pad itself is 5 to 6 inches with reinforcement so the trailer tires don't crack it.
How thick should a generator pad be?
Six inches, reinforced, sized to the installer's template and dead level. Most installers want a pad a few inches larger than the unit on every side and conduit sleeves cast in; send us their spec sheet and we'll pour to it.
What about the water table?
In the wet season it's a foot or two down in most of the city. A slab poured at grade will have wet edges every summer, so we build the pad up on compacted fill with a thickened edge. Sheds stay dry; pads don't grow algae.
Can you pour the pad before the shed is delivered?
Yes — send us the manufacturer's footprint and anchor drawing. Seven days' cure before the shed crew, fourteen for a heavy prefab.
