Lawn & Landscapes

A full artificial grass installation covers site evaluation and design, removal of the existing lawn, base excavation, a compacted angular gravel base over geo-textile filter fabric, turf layout and seaming, edge and perimeter finishing, and the infill system that keeps the blades upright. Synthetic Turf Northwest handles all of it, so the finished lawn is one company's responsibility — and one warranty. 

Under the turf is the part that determines whether a synthetic lawn stays flat for fifteen years or ripples in three. A standard residential build is four layers: geo-textile filter fabric at the bottom, 4–6 inches of compacted angular gravel, the infill system, and the turf itself. Angular rock is used deliberately — the edges lock together under compaction where rounded pea gravel shifts. Depth varies with soil conditions, slope, and drainage, all assessed on site. 

Ask three questions: are they a registered Washington contractor, do they build their own base, and what happens if a seam opens in year six. Synthetic Turf Northwest has installed synthetic lawns across the Puget Sound region since 1996 under WA contractor registration #SYNTHTN850J8, working from the Woodinville headquarters and Fife warehouse. That matters more here than in most markets — a base built for Arizona will not drain a Northwest winter. 

Premium synthetic turf installed over a properly built base typically performs for 15–20 years, and the turf systems used here carry a 15-year manufacturer-backed warranty against fading and wear, plus a workmanship warranty on the installation. UV-stabilized fibers are what hold color through Northwest summers; the base is what holds the surface flat. Lifespan depends far more on install quality than on the turf spec. 

Yes — a correctly installed synthetic lawn drains faster than the sod it replaced. Water passes through the perforated turf backing, down through the infill and the compacted angular gravel, and out through the geo-textile fabric into the subgrade. Grading is set during the base build, so the surface sheds toward the intended discharge point instead of pooling. Sites with heavy clay or a high water table get additional drainage designed before installation.
