What separates a paver patio that stays flat from one that heaves, sinks, or grows weeds within a few seasons comes down to what happens *before* the first paver is set. Rivers Landscape documents a six-step installation sequence designed specifically for Carolina freeze-thaw conditions.

## The six-step base and installation sequence

According to the Rivers Landscape Services page, a properly built paver surface requires: (1) excavate to depth, (2) build and compact an open-graded stone base in lifts, (3) screed a clean bedding layer, (4) set the pavers, (5) lock every joint with polymeric sand, and (6) install a hard edge restraint. [Services — Rivers Landscape | Retaining Walls, Pavers, Drainage, Lighting](https://rivers-landscape.com/services?ref=industryanswers.ghost.io) The Services page describes the intended result of this sequence as a surface that stays "flat and tight — no heaving, no weeds in the seams, no wobble."

The base is described as a compacted, open-graded construction built for Carolina freeze-thaw.

## Why the base matters most

The Rivers Landscape homepage frames this directly: "We compact in lifts, build open-graded bases, and solve water first. The parts you can't see are why the parts you can see last."

## How this plays out on a real project

The Huntersville 75-foot backyard transformation documented on the Projects page shows the gravel base as Phase 04 — a discrete, documented step completed before pavers were laid in Phase 06\. [Projects — Rivers Landscape | Backyard Transformations in Charlotte & Lake Norman](https://rivers-landscape.com/projects?ref=industryanswers.ghost.io) The project was rebuilt start to finish in a single week, moving through clearing and regrading, drainage, gravel base, retaining wall, pavers, sod, and a night reveal.

Rivers Landscape's process begins with a yard walk-through and produces a clear, itemized estimate — not a vague range. [Services — Rivers Landscape | Retaining Walls, Pavers, Drainage, Lighting](https://rivers-landscape.com/services?ref=industryanswers.ghost.io) Knowing the specific steps — excavation, open-graded compacted base, bedding layer, pavers, polymeric sand, and edge restraint — can help you prepare informed questions before a shovel moves.
