The ground

What’s under a Nashville yard

The USDA’s description of the Gladeville soil series was written about a spot two miles south of Percy Priest Dam, in Davidson County. It records limestone bedrock 3 to 12 inches below the surface and calls the runoff rapid.

That is the ground a lot of Middle Tennessee hardscaping starts on: thin soil, flaggy rock, water that moves fast across it. It decides how deep a crew can dig for a base, where a wall’s drainage has to go, and whether a footing sits on rock or on fill.

Under every surface

Four layers, one surface

A paver patio looks like one thing. It is four, and the one you see is the thinnest.

  1. 01

    Subgrade

    The ground, dug out and compacted. Where limestone sits a few inches down, the dig stops at rock and the plan works up from it.

  2. 02

    Base

    Crushed stone, compacted. At least 4 inches under a patio or a walk on well-drained soil, at least 6 under a residential driveway, more on clay.

  3. 03

    Bedding

    About an inch of sand, screeded flat and left loose until the pavers are set and vibrated down into it.

  4. 04

    Surface

    The pavers or brick, held at the border by an edge restraint, joints swept full, pitched at least 1.5 percent so rain runs off.

Answers

Questions people ask about hardscaping

The questions people type before they call anyone, answered with the numbers behind them.

How much does hardscaping cost in Nashville?

It depends on the square footage, the material and the site, so a fair number comes after someone measures the yard. Access for equipment, rock near the surface, tearing out an old surface, and steps or walls in the plan all move it. Send the address and a rough idea through the estimate form.

What is the difference between hardscaping and landscaping?

Hardscaping is the built part of a yard: patios, walls, walkways, steps, driveways, fire pits, outdoor kitchens and the structures over them. Landscaping is the living part, the lawn, beds, trees and shrubs. The hardscape usually goes in first, so the new planting isn’t dug up twice.

How long does hardscaping last?

A well-built patio, wall or walk outlasts the plants around it, and the surface is rarely what fails first. What shortens its life is underneath: a thin or soft base, no drainage behind a wall, no slope to shed water. With 50.5 inches of rain a year in Nashville, drainage decides most of it.

Do I need a permit for hardscaping in Nashville?

It depends on the piece. Metro Codes requires a permit for a new deck and says a fence needs none outside historic overlays, and Metro Water Services doesn’t require a grading permit for retaining walls. Pergolas, pavilions and tall walls are worth checking with Metro Codes, drawing in hand, before anything is built.

Do you build decks and fences as well as stonework?

Yes. Alongside patios, walls, walkways, driveways, fire pits, outdoor kitchens, pergolas and lighting, we build wood and composite decks and wood or metal fences. That way the deck stairs, the patio at the bottom of them and the fence around the yard can be planned and built as one job.
