Project Story

Overview

About 950 square feet of Imperial Desert Rye turf, a Bastione seat and retaining wall on a new footing, and 4x8 Holland paver ribbons set into the existing concrete patio where old brick bands used to be turned a dead backyard in San Diego's 92129 into a finished one. Desert Gold decomposed granite, new planting on drip, 146 feet of drain line and 14 low-voltage lights went in between August 4 and September 1, 2026.

The Challenge

  • The backyard landscaping was outdated and mostly dead, so the yard read as neglected from the house.
  • There was no defined edge or place to sit between the concrete patio and the planting areas.
  • Water and roots both needed managing: new drain lines and a root barrier had to go in before turf, wall and planting.

What Changed

The backyard that was mostly dead landscaping now has about 950 square feet of turf, a capped seat wall framing it, paver ribbons that tie the old patio to the new work, and Desert Gold decomposed granite paths. Drainage runs under all of it, and 14 low-voltage lights make the yard usable in the evening. The crew worked from August 4 to September 1, 2026, with planting and decomposed granite going in last.

How INSTALL-IT-DIRECT Helped

The build started with clearing: dead plants and two inches of soil came out across about 500 square feet, and roots, shrubs and grass were hauled away. Drainage went in next, 146 feet of 3 inch SDR35 line plus perforated pipe, with a root barrier along the planting edge. The Bastione wall was set on a new concrete footing before turf, decomposed granite, planting and lighting finished the yard.

Over 1,000 five-star reviews and 1,500+ San Diego homeowners served.

Design & Build

The Plan

  • Keep the existing concrete patio and replace its old brick bands with 4×8 Holland paver ribbons so it matches the new work.

  • Lay about 950 square feet of Imperial Desert Rye 65 turf as the main open area.

  • Build a Bastione 12 inch seat and retaining wall with caps on a new concrete footing to give the yard a defined edge and extra seating.

  • Finish paths and side areas in Desert Gold decomposed granite with a Belgard Melville curb border.

  • Run 146 feet of 3 inch SDR35 drain line and perforated pipe, and add a root barrier, before any finish surface goes down.

  • Plant agave, a pygmy date palm and other low-water plants on drip, and light the yard with 14 low-voltage fixtures.

The Build

Clearing and demo

Dead plants, roots, shrubs and the top two inches of soil came out across about 500 square feet, and the debris was hauled off before layout.

Drainage and root barrier

The crew trenched and set 146 feet of 3 inch SDR35 drain line plus perforated pipe, and installed about 45 feet of 18 inch deep root barrier along the planting edge.

Wall and footing

A concrete footing was poured for the Bastione 12 inch wall, which was then stacked and capped at seat height.

Paver ribbons and border

About 70 feet of old brick came out of the existing concrete patio, 38 feet of 4x8 Holland paver ribbons went in, and a Belgard Melville curb border was set along the decomposed granite.

Turf, planting and lighting

About 950 square feet of turf went down over a compacted base with antimicrobial infill, followed by planting on drip irrigation, mulch, and 14 low-voltage fixtures on a 150 watt transformer.

Frequently Asked Questions

How much does a backyard turf and seat wall project cost in San Diego 92129?

This backyard came in at about $42,500 to $47,500 for roughly 950 square feet of turf, a Bastione seat wall on a new footing, paver ribbons in the existing patio, decomposed granite, drainage, planting and 14 lights. A similar yard moves with turf area, wall length, drainage needs and plant choices.

Can you add pavers to an existing concrete patio without removing it?

Yes, when the slab is sound. On this project the crew removed the old brick bands from the existing concrete and set 4x8 Holland paver ribbons in their place, so the old patio matches the new turf, wall and border and the slab did not have to be demolished.

Why install a root barrier before turf and planting?

Roots from nearby trees can lift edging, wall footings and turf seams over time. About 45 feet of 18 inch deep root barrier went in along the planting edge here before any finish work.

How long did this backyard take to build?

The crew was on site from August 4 to September 1, 2026, about four weeks including planting and final details, and the project closed out September 17.
