Artificial grass installed in Las Vegas succeeds or fails beneath the surface. The infill that props up the fibres, the base that drains water away, the seams that stay sealed, and the compaction that keeps everything stable are invisible once the work is done, but they determine whether your turf will last ten years or fail in two. This guide walks a homeowner through each layer of a proper installation: what infill is, how much of it you need, what goes under the turf, how to prepare the hard desert soil and caliche that underlies most Vegas yards, and how drainage works in a climate where spring winds are fierce and summer monsoons can dump an inch of rain in an hour.
Whether you are installing turf in a residential backyard, a pet area or dog run, a pool surround, or a commercial property, the principles are the same: proper base preparation and drainage matter more than the turf itself. This guide is written for homeowners in the Las Vegas Valley and surrounding areas who want to understand what they are paying for and how to verify that a turf installer is doing the job right.
Turf Infill Options: Silica, Coated Sand, Zeolite and Envirofill
Infill is the material spread on top of the turf after installation. It serves multiple purposes: it props up the synthetic fibres so they stand upright and feel natural underfoot, it protects the turf backing from ultraviolet light, it adds weight so the turf stays in place in wind, and it helps water drain through the system. The most common infill is silica sand, a basic ballast material that is inexpensive and effective. Silica sand is angular and compacts over time, which is why some installers prefer coated sand, a rounded silica particle with a polymer or mineral coating that stays more uniform, feels slightly softer, and can be tinted to blend with the turf colour. Both are widely used in residential yards across Las Vegas.
Zeolite is a porous mineral that absorbs and neutralizes odours and ammonia, making it popular in pet turf and dog runs where urine drainage is a concern. Zeolite is often blended with sand rather than used alone. Antimicrobial and cooling coated infills, sold under brand names such as Envirofill, are engineered to reduce odour-causing bacteria and to lower the surface temperature of the turf in full sun. These products cost more than basic sand but can be worth the investment in high-traffic pet areas or in yards where heat is a concern. Crumb rubber, made from recycled tires, is standard in sports fields and synthetic turf courts because it provides cushioning and performance characteristics suited to athletic play; it is not commonly used in residential yards. Any infill you choose should be specified in writing before installation begins.
How Much Infill Artificial Grass Needs, and Why
Infill is measured in pounds per square foot, and the amount matters. A typical residential turf installation uses between 1.5 and 3 pounds of infill per square foot, depending on the turf product, the fibre type, and the intended use. Pet areas and high-traffic zones may call for the higher end of that range. The infill serves critical functions: it holds the fibres erect so they do not mat down, it shields the backing material from UV degradation, it weights the turf so wind does not lift the edges, and it fills the space between fibres to help water percolate through. Too little infill is a common shortcut taken by installers working on a tight budget. A turf installed with insufficient infill will mat quickly, drain poorly, and show backing or weave patterns that should not be visible.
The exact amount for your yard depends on the product specification, and reputable installers will provide this figure in writing before work begins. Do not accept a vague promise that the turf will be "properly filled." Ask for the infill type and the pounds per square foot in your written quote. When the job is complete, you should not see the backing weave, and the fibres should spring back when you brush your hand across them. If you are unsure whether your turf has enough infill, contact the installer or call for a free estimate to have it inspected.
What to Put Under Artificial Grass for Drainage
What lies beneath artificial grass determines how well it drains and how long it lasts. The process begins with removal: if you have an existing lawn, dead grass, or old turf, it must be removed completely, including roots and thatch, down to bare soil. Once the area is cleared, excavation follows. The depth of excavation depends on the base material you will use and the existing grade, but typically the excavated area should be graded to slope slightly away from the house and away from any pool or structure to prevent water from pooling against foundations. In most cases, a slight grade of one-quarter inch per foot is sufficient.
After grading, a weed barrier (a landscape fabric that blocks weeds but allows water through) is laid on the bare soil in most residential installations. This prevents weeds from pushing up through the turf. Next comes the base layer, typically three to four inches of decomposed granite or crushed base rock, which is compacted firmly using a plate compactor. This compacted base is the foundation that prevents settling and dips. On hard surfaces such as concrete patios, balconies, or decks, a draining underlay or pad is laid down instead of a gravel base. For pet areas, a permeable pad designed to accelerate drainage and contain odour is often installed between the base and the turf. Finally, the turf itself is laid, seamed, nailed, and infilled. Each layer has a purpose, and skipping any step is a shortcut that shows up later as settling, odour, or poor drainage.
Base Prep on Las Vegas Caliche: Excavation, Base Rock and Compaction
Las Vegas sits on a flat Mojave basin with hard desert soil and caliche, a calcium carbonate hardpan that forms just below the surface and sheds water rather than absorbing it. This is why base preparation is not optional in the Las Vegas Valley. Without proper excavation, grading, and compaction, water will pool under the turf, odours will develop (especially in pet areas), and the turf will settle unevenly, creating dips and soft spots. The process begins with excavation to remove the existing lawn and to expose the native soil. The excavated area is then graded to slope away from the house and pool at a gentle pitch, typically one-quarter to one-half inch per foot. This ensures that water runs off rather than collecting beneath the turf.
Once graded, the base material (decomposed granite or crushed base rock, typically three to four inches deep) is spread and compacted in lifts using a plate compactor. Compaction is done in multiple passes, pressing each layer firmly so that the base becomes a solid, stable platform. An uncompacted base is a leading cause of settling, dips, puddles, and odour problems that develop months or years after installation. In yards with existing water problems, poor drainage, or standing water after rain, the drainage issue must be addressed before turf installation begins. In some cases, this means installing a French drain, regrading the yard, or other drainage work that falls outside turf installation. We work with homeowners to identify these issues during the estimate and will decline a job if drainage cannot be resolved, because installing turf over a water problem is a waste of your money.
Artificial Grass Drainage and Underlay: Perforated vs Fully Permeable
Artificial grass backing comes in two forms: perforated and fully permeable. Perforated backing has small holes that allow water to drain through, while fully permeable backing (sometimes called open-weave or non-woven) allows water to flow through the entire backing material. The drainage rate is measured in gallons per hour per square foot. A typical residential turf drains between 5 and 15 gallons per hour per square foot, depending on the product. In Las Vegas, where monsoon thunderstorms can drop heavy rain in a short time, and where pet urine is a constant concern, drainage performance matters. A fast-draining turf is only as good as the base beneath it, however. If the base is compacted poorly or if the grade does not slope away from the house, water will sit under the turf no matter how permeable the backing is.
For pet areas and dog runs, an additional drainage underlay or pad is often installed between the compacted base and the turf. These pads are designed to accelerate water movement away from the surface, prevent pooling, and in some cases contain antimicrobial agents to reduce odour. On hard surfaces such as patios and balconies, a draining pad is essential because concrete or pavers do not absorb water; without it, water will sit on the surface and eventually cause odour and mold. Ask your installer for the drainage rate of the turf product in writing, and ask whether the base will be graded and compacted to slope away from structures. These details are what separate a thoughtful installation from a quick one.
Seams, Nails, Edging and Power Brooming
The finishing details of a turf installation reveal the quality of the work. Seams are the joints where two pieces of turf meet, and they must be sealed properly to stay tight and invisible. A professional seam is joined using seam tape (a waterproof adhesive strip) applied to the underside of the joint, with the grain of the turf fibres aligned so the seam runs in the direction the fibres naturally fall. Once sealed, the seam is reinforced with nails or staples placed at the correct spacing (typically every 4 to 6 inches) to hold the pieces together until the adhesive sets. A visible seam, a lifted seam, or one that separates after a few months is a sign of poor workmanship. In Las Vegas, where spring winds are strong and summer heat is intense, seams that are not properly sealed or nailed can lift or melt if they receive direct afternoon sun reflection from a window or pool deck.
Edges are equally important. The perimeter of the turf should be secured with nails or staples to the base and finished with edging material such as bender board, a metal edge, or a secured perimeter strip that prevents the turf from fraying or lifting. Turf installed on patios or near pavers should be cut tight to the edge with no overhang. After installation, the turf is power broomed, a process that stands the fibres upright, spreads the infill evenly, and gives the lawn a uniform appearance. A power-broomed turf looks fuller and more natural than one that is left flat. If your turf looks matted or uneven after installation, or if you can see the backing weave or seams clearly, ask the installer to power broom and add infill. These are finishing touches that take time but are part of a complete job.
What a Written Turf Spec Should Include
Before any turf installation begins, you should receive a written specification that details every material and method that will be used. A proper spec protects you and holds the installer accountable. It should include the following: the turf product name and fibre type (polyethylene, polypropylene, or nylon), the face weight in ounces per square yard, the pile height in millimeters, the backing type and drainage rate in gallons per hour per square foot, the infill type and pounds per square foot, the base material and depth (typically 3 to 4 inches), the base compaction method, whether a weed barrier will be installed, the seam method and edge treatment, cleanup and haul-off of existing material, and the workmanship warranty period (typically one to three years on the installation itself). The spec should also note any site-specific conditions, such as grading for drainage or the removal of an existing lawn.
A written spec is not a sales document; it is a contract that describes exactly what you are paying for. It allows you to compare quotes from different installers and to hold any installer accountable if the work does not match the spec. When you receive a quote, ask for the spec in writing before you commit. If an installer is vague about product details, infill amounts, or base depth, that is a red flag.
