Installation failures often stem from poor preparation. Understand the correct sequence of digging depth, weed barriers, and spraying weed suppressants to lay a century-old foundation for the lawn Proper site preparation is the single most critical step to ensure a long-lasting, wrinkle-free, and weed-free artificial lawn. Many DIY and even professional installations fail early because installers skip or rush key prep steps. This complete standard operating procedure (SOP) walks you through every stage: removing old grass, controlling excavation depth, blocking weeds permanently, and protecting underground utilities. Following these rules will create a solid foundation that lasts 8–10 years with zero issues. For more installation insights, visit our Turflory FAQ Page.

The biggest mistake you can make is laying artificial turf directly over existing grass or weeds. Natural grass will rot, create uneven settling, emit odors from organic matter decay, and push upward through your new lawn. Weeds will eventually break through and ruin the appearance and stability. Always start with a completely clean, bare subgrade. Skipping this step guarantees future problems, no matter how high-quality your turf may be. A successful install requires full removal of vegetation, proper soil removal, graded base, and reliable weed prevention. This is not a step to rush—it is the foundation of your entire project.
For efficient and clean removal of old lawn, a sod cutter for turf prep is the best tool. This machine slices under the root zone and lifts old grass in uniform strips, saving hours of manual labor. Start by mowing the existing grass as short as possible. Run the sod cutter along the length of the yard, cutting strips 12–18 inches wide. Remove all strips, including roots and thatch. For small areas or tight spaces, use a sharp spade or turf cutter. After stripping, rake away remaining debris, roots, and stones to create a clean working surface. This step ensures no living organic material remains to cause decay or unevenness.
Correct artificial turf excavation depth directly affects drainage, stability, and longevity. Most residential installations require removing 2–4 inches of topsoil. For heavier-use areas like playgrounds or pet zones, excavate 4–5 inches to accommodate a more compacted base. The goal is to reach firm, undisturbed subsoil. Over-excavation leads to unnecessary base material costs; under-excavation causes poor drainage and sinking. After digging, use a rake and level to create a level surface with a gentle 1–2% slope for water runoff. Compact the subgrade with a plate compactor to avoid future settling. This step ensures your base remains stable for years.
Weeds are the top long-term complaint with artificial lawns. Defeat them with a two-layer system: pre-emergent herbicide plus commercial-grade weed barrier fabric. First, apply a non-residual, turf-safe pre-emergent herbicide to the entire prepared subgrade. This stops dormant weed seeds from germinating. Allow the chemical to dry fully before proceeding. Next, roll out heavy-duty, commercial-grade weed control cloth. Overlap seams by 6–8 inches and secure with landscape staples. Cover the entire area—no gaps, no folds. This barrier blocks weeds from below while allowing water to drain. Avoid cheap landscape fabric, which tears quickly and fails. A proper weed barrier ensures you will prevent weeds fake grass permanently.
Before you dig, call 811 or your local utility location service to mark utility lines check for water, power, gas, and cable. Damaging lines is dangerous and expensive. If you have an underground sprinkler system, plan to either remove heads and cap lateral lines (irrigation capping) or adjust them to sit above the finished turf height. Mark all lines and heads with stakes or spray paint. Avoid digging or compacting directly over pipes. Taking these precautions prevents leaks, breaks, and costly repairs after your lawn is installed.
By following these standard operating procedures, you eliminate the most common causes of artificial lawn failure: weeds, unevenness, sinking, and drainage issues. Proper prep takes time but delivers a level surface, clean look, and decades of trouble-free performance. With Turflory’s high-quality turf and professional prep, your lawn will look pristine year-round.
