Artificial grass looks simple from the yard, but what lies beneath the surface determines whether your turf will drain properly, stay in place, resist the intense Henderson heat, and serve you for years without settling, odor, or seam failure. This guide walks you through infill options, base preparation, drainage design, and the finishing details that separate a durable installation from one that will disappoint. Whether you are installing turf in a residential yard, a pet area, around a pool, or on a commercial property, understanding these fundamentals will help you ask the right questions and verify that your installer is building to last.
Henderson's soil runs from sand to caliche and rocky hillside, and summer temperatures regularly exceed 115 degrees Fahrenheit. The base and infill you choose must handle both the drainage demands of occasional desert storms and the thermal stress of months of intense sun. This guide is written for homeowners and property managers in Henderson and the surrounding areas who want to know what goes into a professional installation, what to ask for in writing, and how to spot the difference between a thorough job and a shortcut.
Turf Infill Options: Silica, Coated Sand, Zeolite and Envirofill
Infill is the material spread across the turf surface after installation. It serves multiple purposes: it props the synthetic fibres upright so they look and feel natural, protects the backing from ultraviolet light, adds weight to keep the turf from shifting, and plays a role in how water drains through the system. The most common infill is silica sand, a basic ballast material that is inexpensive and effective for general residential use. Silica sand is angular and compacts firmly, which is why it holds its place even under foot traffic and in the wind that Henderson experiences in spring.
Coated sand infills improve on plain silica by rounding the grains and sometimes adding color or a polymer coating. Rounded grains feel gentler underfoot and are often preferred in residential yards and play areas. Zeolite is a porous mineral that absorbs moisture and odors, making it popular in pet turf installations where urine control is important. Antimicrobial and cooling coated infills, such as Envirofill, combine these benefits with additives designed to reduce bacterial growth and lower surface temperature in full sun. Crumb rubber, made from recycled tires, is standard in sports fields and athletic courts where impact absorption matters, but it is rarely used in residential yards because it retains heat, can migrate, and requires more frequent maintenance. The right infill choice depends on your use case, climate tolerance, and maintenance preferences, all of which your installer should discuss with you before the job begins.
How Much Infill Artificial Grass Needs, and Why
Infill is specified in pounds per square foot, and this number directly affects how well your turf performs. A typical residential installation uses between 2 and 4 pounds per square foot, depending on the turf product, the pile height, and the intended use. Heavier infill loads are common in pet areas and playgrounds where the turf sees heavy use and odor control is critical. The infill holds the fibres upright, so too little infill causes the grass to look flat and matted within weeks. It also shields the backing from UV degradation, which becomes significant in Henderson's relentless sun. Infill adds weight that helps anchor the turf against wind and foot traffic, and it participates in drainage by allowing water to flow through to the base below.
One of the most common shortcuts in cheap installations is under-filling. An installer may use only 1 to 1.5 pounds per square foot to save material cost and labor time, and the result is turf that looks worn, feels thin, and fails to control odor or protect the backing. Always ask your installer for the infill specification in writing, including the type and the pounds per square foot. This number should be part of your written estimate and should match the turf manufacturer's recommendations for the product you have chosen. If an installer cannot or will not give you this figure in advance, that is a sign to look elsewhere.
What to Put Under Artificial Grass for Drainage
The layers beneath artificial grass are as important as the turf itself, because they determine whether water drains away or pools, whether the surface settles unevenly, and whether odor builds up in the soil below. The first step is always removal. If you have an existing lawn, it must be stripped away completely, including roots and thatch, so that you are starting with bare soil. If old turf is being replaced, the old turf and any deteriorated base must come out. Once the area is cleared, excavation begins. The depth depends on your soil, the base material available, and the drainage needs of your site. In Henderson, where caliche and rocky soil are common, excavation may need to go deeper to reach workable material or to create proper drainage fall.
After excavation, a weed barrier (typically a permeable landscape fabric) is laid to prevent weeds from growing up through the infill and to separate the base from the native soil below. The base layer itself is typically 3 to 4 inches of decomposed granite, crushed limestone, or other free-draining base rock, compacted firmly in lifts using a plate compactor. Compaction is essential: an uncompacted base will settle over time, creating dips and puddles where water collects and odor develops. On hard surfaces such as concrete, patios, or balconies, an optional draining underlay or pad is laid between the base and the turf to allow water to flow to the edges and away. The turf is then laid on top, with seams sealed and edges secured. Never install turf directly onto a concrete slab without drainage: water will pool beneath it, and the backing will degrade.
Base Prep on Henderson Soil: Excavation, Base Rock and Compaction
Henderson's soil presents specific challenges for base preparation. The area includes caliche, a hard, calcium-carbonate layer common in the desert, as well as rocky hillside soils and pockets of clay. Caliche can block drainage, so if your site has a caliche layer close to the surface, it must be broken up or removed during excavation. Rocky soil requires screening or replacement with workable base material. The goal is to create a stable, free-draining foundation that will not settle or hold water. Excavation depth typically ranges from 3 to 5 inches, depending on the existing soil and the base material available. The site must also be graded so that water runs away from the house and away from any pool or structure, creating a gentle fall that prevents ponding.
Once the site is excavated and graded, base rock is spread in layers and compacted firmly. A typical installation uses 3 to 4 inches of compacted base material, applied and compressed in 1 to 2 inch lifts using a plate compactor. Each lift must be compacted before the next is added, so that the entire base is firm and stable. An uncompacted base will settle unevenly over months or years, creating low spots where water pools and where odor can develop, especially in pet areas. Compaction also prevents the turf from shifting under foot traffic and wind. In Henderson's gusty spring weather, a well-compacted base keeps the turf anchored. If your yard has a history of water problems, poor drainage, or standing water after rain, these issues must be addressed before turf installation. If the site cannot be drained adequately, we will recommend fixing the drainage first or declining the job, because no turf installation can overcome a fundamental water problem in the soil below.
Artificial Grass Drainage and Underlay: Perforated vs Fully Permeable
Artificial grass itself is permeable, but the rate at which water passes through varies by product. Drainage is measured in gallons per hour per square foot (GPH/sq ft). A typical residential turf drains at 15 to 30 GPH/sq ft, meaning that water moves through the backing and infill relatively quickly. However, a fast-draining turf still fails on a base that does not drain. This is why base preparation and compaction are so critical. Water must be able to move down through the infill, through the backing, and into the base below. If the base is clay or compacted poorly, water will sit on top of the backing, and the turf will become waterlogged and odorous. In pet areas, drainage is put to the real test: urine must drain away quickly so that it does not pool and create odor. Heavy rain is rare in Henderson, but when it comes, a well-draining system handles it without flooding.
The backing of the turf itself comes in two types: perforated backing, which has small holes punched through it to allow water to flow, and fully permeable backing, which allows water to pass through the material itself. Fully permeable backings generally drain faster and are preferred in pet areas and high-use zones. On hard surfaces such as concrete, patios, balconies, or pool surrounds, an optional draining underlay or pad is installed beneath the turf. This pad sits on the hard surface and allows water to flow to the edges, where it drains away. Edge drainage details are critical on hard surfaces: water must have a path to exit the turf perimeter, or it will pool underneath. Ask your installer for the drainage rate of the turf product in writing, and ask how the base and any underlay will handle water in your specific situation.
Seams, Nails, Edging and Power Brooming
The finishing details of a professional installation are visible in how seams are joined, edges are secured, and the surface is prepared for use. Seams are the joints where two pieces of turf meet, and they are a common point of failure in poor installations. A proper seam is joined with seam tape and a polyurethane adhesive applied to both sides of the tape, with the grain of the turf carefully aligned so that the seam is invisible or nearly so. The tape holds the two pieces together while the adhesive cures, and the aligned grain prevents the seam from showing as a visible line. After the adhesive sets, the seam should flex naturally with foot traffic and temperature changes without lifting or tearing. Visible seams, lifted edges, and gaps between pieces are signs that an installer rushed the work or did not understand the importance of grain alignment and proper adhesive technique.
Edges are secured with galvanized nails or staples spaced at the right intervals (typically 6 to 8 inches) around the perimeter, and the perimeter itself is finished with bender board, landscape edging, or a secured border that prevents the turf from rolling back or shifting. On patios and hard surfaces, turf is cut tight to pavers and other features so that there are no gaps where water or debris can collect. After installation, the entire surface is power broomed, a process that stands the fibres upright and spreads the infill evenly across the surface. Power brooming also helps the turf settle and look full and natural. If your new turf looks flat, matted, or uneven after installation, or if seams are visible or pulling apart within the first few weeks, the installation was not finished properly.
What a Written Turf Spec Should Include
Before any installation begins, ask your turf installer for a written specification that details every material and method that will be used. This spec is your protection and your proof that the job was done to a defined standard. A complete written spec includes the turf product name and fiber 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 the amount in pounds per square foot, the base material and depth (typically 3 to 4 inches), the base compaction method, whether a weed barrier will be used, the seam joining method, the edging type, cleanup and haul-off, and the workmanship warranty period. This spec becomes part of your estimate and contract, so both you and the installer are clear on what will be delivered.
A written spec also protects you from shortcuts. An installer who will not provide a spec in writing, or who uses vague language such as "quality infill" or "proper base prep" without numbers, is signaling that corners may be cut. Our fully insured team provides a written specification for every job, measured on site and tailored to your soil, drainage, and use case. If you are comparing estimates from multiple installers, the spec is your tool for comparing apples to apples. Two turf products that look similar may have very different face weights, pile heights, and drainage rates, and the infill amounts and base depths can vary widely. Ask every installer for the same information in writing, and you will see the real differences.
