To lay artificial grass that lasts, an installer strips the old lawn and several inches of soil, builds a crushed-stone base in thin compacted layers, adds a weed barrier, rolls the turf out with every piece's grain facing the same way, seams it, fastens the edges, and brushes in infill. The base is the part that decides whether it survives a New England winter, and it is also the part you cannot see once the turf is down. So if you are paying for an install, the most useful thing you can do is check the work at each stage, before it gets covered.
Zacarias Tree & Landscaping, a family-run landscaping company in Lynn, builds natural lawns with sod and hydroseed and does not install synthetic turf. This guide is for North Shore homeowners who have decided to hire a turf installer, or are close to it, and want to know what good work looks like.
The install in brief
- Mark and plan: measure, map where rain runs, and lay out rolls to keep seams few and out of walking paths.
- Excavate: remove sod, roots, and soil, and slope the subgrade away from the house.
- Base: spread crushed stone in layers, dampen, and plate-compact each one.
- Weed barrier: a permeable fabric over the base, overlapped and pinned.
- Turf: unrolled, relaxed in the sun, grain aligned.
- Seams: factory edges trimmed, tape and adhesive underneath, edges pressed tight.
- Edges: turf trimmed to an edging restraint and fastened.
- Infill: spread in passes and brushed against the grain.
What North Shore ground does to a turf base
A base that works on sandy ground in a warm state can fail here. Local conditions an installer should talk about before digging:
- Heavy clay and fill: plenty of yards around Lynn and the North Shore have dense clay or old fill soil that drains slowly. Water that passes through the turf has nowhere to go and sits in the stone.
- Ledge and glacial stone: shallow rock can stop an excavator short of the planned depth. The fix should be a plan (more grading, a drain, or a shallower layout), not a thinner base.
- Tree roots: digging a base inside the root zone of a mature oak or maple can injure the tree. Large roots should be worked around, not cut through to save time.
- Freeze and thaw: the North Shore cycles above and below freezing many times each winter. Wet stone heaves each time it freezes, which is how ripples and dips appear by March.
- Buried lines: a proper installer requests a Dig Safe mark-out before excavation, and asks you about private lines such as irrigation and lamp post wiring.
Checkpoints while the work is happening
Ask the crew to let you see, or photograph, each of these before the next layer covers it:
| Stage | Good sign | Warning sign |
|---|---|---|
| Excavation | Even depth across the area; subgrade sloped away from the house | Old sod left in place, or low spots that hold water after a rain |
| Base | Stone added and compacted in several thin layers; a footprint barely marks it | One thick dump of stone raked flat, or no compactor on site |
| Drainage | A plan for where water goes on heavy soil, such as a drain pipe or deeper stone | No answer to "where does the water go?" |
| Weed barrier | Overlapped and pinned, covering the base to the edges | Gaps at edges and around trees |
| Seams | Tight joints, fibers leaning the same way, no glue on the blades | Visible lines, gaps, or ridges where pieces meet |
| Edges | Solid restraint, fasteners at regular spacing | Turf tucked into soil or held with a few stakes |
What to inspect after the first winter
The first spring tells you whether the base was built for this climate. Once the snow is gone, walk the turf and look for:
- Ripples or waves that were not there in the fall
- Dips or soft spots that give underfoot, often in traffic lanes or near downspouts
- Puddles that stay more than a few hours after rain
- Lifted or loose edges, especially where snow was piled or shoveled
- Opened seams or seams that now show as a line
- Weeds along the edges or coming up through drainage holes
Photograph anything you find and compare it with the photos you took at install. Many warranties set a window for reporting problems, so read yours before the season gets busy.
Base problem or surface problem?
Some issues are cosmetic and cheap to fix. Others mean the turf has to come up.
| What you see | Usually means | Typical fix |
|---|---|---|
| Matted fibers in paths | Surface wear | Brushing and infill top-up |
| A loose edge in one spot | Fastener or edging issue | Re-fasten along the restraint |
| Waves across a wide area | Turf not relaxed before fastening, or base movement | Re-stretch if the base is sound; rebuild if not |
| Dips and soft spots | Base not compacted in layers | Lift turf, rebuild and compact the base |
| Standing water | Thin base or no drainage plan on heavy soil | Lift turf, add drainage or depth |
| Heaving after winter | Water freezing in the base | Lift turf, correct drainage and base |
If a base has to be rebuilt, much of the original labor is repeated. That is why the checkpoints above matter more than the brand of turf.
When the better answer is a real lawn
Many yards that seem to need turf really need soil repair, drainage, or a grass matched to the light. The UMass Extension turf program has Massachusetts lawn guidance on soil testing, seed choice for shade, and renovation timing. Before committing, see what drives the price in our guide to artificial lawn cost per square foot, and weigh ownership costs over time in our artificial grass vs natural lawn comparison. Our lawn installation and renovation service handles the grading, soil work, and sod or hydroseed.
Frequently Asked Questions
What do you put under artificial grass?
A compacted crushed-stone base a few inches deep, with a weed barrier on top. On heavy or wet soil, a separator fabric or a drain pipe may go in below the stone.
Can you lay artificial grass directly on soil?
Not if you want it to last. Soil shifts, holds water, and settles unevenly, so turf laid on it ripples and puddles. In a freeze-thaw climate like ours, those problems show up in the first winter.
How can I tell if my turf base was done right?
Watch for compaction in several thin layers during the install, and check the surface the first spring. Dips, soft spots, standing water, and heaving all point to the base.
Which way should artificial grass face?
Every piece should have its fibers leaning the same direction, usually toward where you view the yard most, such as the back door. Mixed grain shows up as visible seams.
How long does it take to lay artificial grass?
Most of the time goes into excavation and base work. A small yard can take a crew a day or two; rock, roots, and drainage work add time.
