Paver patio and walkway installation in Naples, pitched the right way

Away from the house slab and away from the pool, toward ground or a drainage detail that can take an afternoon storm. Pitch decides the target, and the target is chosen before the first paver goes down. Standing water at the lanai edge or a damp line on the slab means the pitch is sending water to the wrong place, and that is a grading fix, not a paver fix.

Start with the house. A patio pitched toward the home sends every afternoon storm against the slab edge, and the evidence arrives in a fixed order: water standing along the lanai edge after rain, then a damp line on the outside of the slab, then staining that keeps coming back after pressure washing. Left alone, that water works on the ground beside the stem wall season after season. None of it announces itself quickly, which is why the pitch matters more than the pavers do.

The pool is the other forbidden target. Water crossing the pavement toward the pool carries fine material out of the base as it goes and delivers its load to the ground behind the shell, which gets its own section further down this page. Everything else on the property is a candidate: lawn, planting beds, a swale, a drainage detail built for the purpose. The rule we work to is simple. Choose the target first, then set the pitch to reach it.

The published specification backs this up with a number. The Concrete Masonry and Hardscapes Association puts minimum surface slope for interlocking concrete pavement at 1.5% (CMHA, Tech Note PAV-TEC-002, 2022), which works out to roughly three sixteenths of an inch per foot. That number gets a patio shedding water instead of holding it. What it cannot do is say where the water goes. "Away from the patio" is not a plan, and a patio can meet the slope number perfectly and still aim its storm at the slab.

Sizing matters here because of how Naples rain arrives. A summer afternoon storm drops water faster than sandy ground can absorb it at the surface, so for those minutes the ground is effectively sealed and everything the patio sheds is moving. The fall has to deliver that water to ground that can take it once the storm passes, not just to the nearest edge. In the wet season much of the low ground in Collier County is already doing stormwater work, so the target has to be chosen honestly rather than optimistically.

Where a site has no good target, the honest answer is a drainage detail named as its own scope: a channel drain across the fall, a gravel margin along the problem edge, or a permeable section built to take the storm itself. Permeable interlocking pavement stores water in an open graded base beneath the pavers, and over soils that will not absorb it, perforated underdrains carry the water out to an outlet (CMHA, Tech Note PAV-TEC-018, 2022). That is extra work and we say so up front, because a patio that quietly floods the yard next door is not a finished job either.

The good news is that pitch is fixable without redoing everything. If water stands in one low spot and nothing else has changed, the base has usually settled there, and that area alone can be lifted, re-based and reset, the same repair we make on decks and describe on the pool deck repair page. If water runs the wrong way along a whole edge, the fix is regrading that run. Older patios in Naples Park tend to need the first; patios regraded for a later feature tend to need the second. What a localized reset cannot fix is a patio that was pitched at the house from the start, and we will say which situation yours is after seeing it, rather than resetting pavers that will send water at the slab again.
