Artificial grass looks good in a photograph, but what makes it last through Fort Worth's heat, spring storms, and hard clay soil is what lies beneath and inside it. This guide walks a homeowner through infill choices, base preparation, drainage design, and the finishing details that separate a durable installation from one that fails within a few years. Whether you are converting a lawn that has died in drought, building a dog run that does not turn to mud, or preparing a yard for sale or an event, understanding these layers helps you ask the right questions and verify the work.
Fort Worth spreads across three soil types: limestone prairie to the west, Blackland clay to the east, and sandy Cross Timbers to the north. Each drains differently, and each demands a different approach to base prep. The guide covers infill materials and weights, base rock and compaction, drainage rates and underlays, seams and edging, and the written specification you should demand from any turf installer, including us.
Turf Infill Options: Silica, Coated Sand, Zeolite and Envirofill
Infill is the material spread on top of the turf after installation. It serves four jobs: it props up the synthetic fibres so they stand and feel natural underfoot, it protects the backing from UV damage, it adds weight so the turf does not shift in wind or under foot traffic, and it helps water drain through the turf and into the base below. The most common infill materials fall into distinct families, each with different properties and costs.
Silica sand is the baseline infill. It is inexpensive, widely available, and works as a ballast. Standard silica is angular and can compact over time, which is why cheaper installations sometimes use it alone and then watch the turf settle and bare spots emerge. Coated sand rounds the grains and often adds a thin coating (acrylic, polyurethane, or ceramic) to reduce dust, slow compaction, and sometimes add colour or a slight cooling effect. Coated sand is gentler on fibres and performs better under heavy use. Zeolite is a porous mineral that absorbs and neutralizes ammonia and odors, making it the standard choice for pet turf and dog runs. It does not replace other infill but is often blended in at 10 to 20 percent by weight. Antimicrobial and cooling coated infills, sold under names such as Envirofill, add a surface treatment designed to reduce bacterial growth and lower turf temperature in direct sun. These materials exist and are available to source, though they carry a cost premium.
Crumb rubber (recycled tire rubber) is used in sports fields and athletic courts where impact absorption matters, but it is not a residential choice for most yards. It retains heat, can migrate into soil over time, and is not recommended for areas where children play or pets spend time. A homeowner should ask what infill is specified and why, and should receive the answer in writing.
How Much Infill Artificial Grass Needs, and Why
Infill is measured in pounds per square foot, and the amount matters more than many homeowners realize. Too little infill is a common shortcut taken by installers working on a tight budget. The fibres do not stand upright, the backing is exposed to UV, and the turf wears and compacts faster. The correct amount depends on the pile height and density of the turf product itself, but typical residential installations call for 1.5 to 2.5 pounds per square foot, with pet areas and heavy-use zones sometimes running higher. A putting green or sports turf has its own specification, often tighter and more precise.
The infill amount should be stated in your written specification before work begins, and you should ask the installer how they will verify it during installation. Some crews measure and record the weight of infill delivered and spread; others rely on depth and visual inspection. A specification that does not name a target weight in pounds per square foot is incomplete. If an installer cannot or will not commit to a figure in writing, that is a sign to ask why. After installation, settling and compaction will gradually reduce the infill level, which is why periodic turf cleaning and infill top-up is part of long-term care for pet areas and high-traffic zones.
What to Put Under Artificial Grass for Drainage
The foundation under artificial grass must remove water quickly, or the turf will hold moisture, odors will develop, and the backing will degrade. Start by removing the existing lawn or old turf and as much root material as practical. If the yard is currently bare or compacted, excavate to remove topsoil and organic matter down to firm subgrade. The depth of excavation depends on the soil type and the desired finished grade, but typically two to four inches are removed to make room for the base layers that follow.
Next, lay a weed barrier (a non-woven geotextile fabric) over the subgrade if weeds are a concern. The barrier stops roots from growing up into the turf while allowing water to drain through. On top of the barrier, install a free-draining base of decomposed granite or crushed base rock, typically three to four inches thick. This base must be compacted in lifts (thin layers) with a plate compactor to create a firm, stable platform. An uncompacted base will settle unevenly, creating dips and soft spots where water pools and odors linger.
For residential yards, that base layer is often sufficient. For pet areas, patios, or playgrounds, an optional draining underlay or cushioning pad can be added between the base and the turf. This layer provides comfort underfoot and additional drainage insurance. On hard surfaces like concrete or a balcony, a draining underlay is essential. Never install turf glued flat to a concrete slab that does not drain; water will pool beneath the turf, backing will rot, and the installation will fail within months.
Base Prep on Fort Worth Caliche: Excavation, Base Rock and Compaction
Fort Worth's soil presents a real challenge for drainage. The Blackland clay to the east and the limestone caliche across the prairie drain slowly and compact hard. If you dig a hole and it fills with water, you have a drainage problem that base prep alone may not solve. The answer is excavation, grading, and firm compaction of a free-draining base material, typically three to four inches of decomposed granite or crushed limestone base rock.
Begin by excavating the yard to remove topsoil and organic matter down to firm subgrade. Grade the finished surface with a slight fall (slope) away from the house, the pool, and any structures, so water runs off rather than pooling. This is especially important in Fort Worth, where spring storms can deliver heavy rain quickly. Once the subgrade is graded and level, spread the base rock in lifts of one to two inches and compact each lift firmly with a plate compactor. Proper compaction is the difference between a stable surface and one that settles into dips and soft spots over time. Uncompacted base material will shift under foot traffic and weight, creating low spots where water collects and odors develop, particularly in pet areas.
If your yard has a genuine water problem (standing water after rain, a high water table, or poor percolation), drainage must be addressed before turf is installed. This might mean installing a French drain, regrading the yard, or installing a subsurface drainage system. These solutions are outside the scope of turf installation, but they are necessary for a durable result. If base prep and grading cannot solve the water problem, we will walk away rather than install turf that will fail. Contact the Fort Worth building department or a drainage specialist if you are uncertain whether your yard has a water issue that needs professional attention.
Artificial Grass Drainage and Underlay: Perforated vs Fully Permeable
Artificial grass itself must drain quickly. The backing of the turf can be either perforated (small holes punched through) or fully permeable (a material that allows water to flow through it). Perforated backing drains at a slower rate, typically 10 to 20 gallons per hour per square foot, while fully permeable backing can drain at 40 gallons per hour or higher. In Fort Worth's climate, where spring storms deliver heavy rain and summer heat demands fast evaporation, a fast-draining turf is the safer choice, especially for pet areas where urine must drain quickly to prevent odor and ammonia burn.
However, even the fastest-draining turf will fail on a base that does not drain. If the base is uncompacted, poorly graded, or built on clay that holds water, the turf will sit on a wet platform and the backing will rot or delaminate. The real test of drainage is a heavy rain or, in a pet area, daily use. If water pools on the surface or beneath the turf, the problem is usually in the base, not the turf itself. For hard surfaces like patios, balconies, and rooftops, a draining underlay or cushioning pad is installed between the base and the turf to manage water that cannot drain into soil. On a balcony or rooftop, edge drainage must also be designed so water does not collect at the perimeter.
When you receive a quote or specification, ask the installer to name the drainage rate of the turf backing in gallons per hour per square foot. If they cannot provide that figure, ask why. A vague answer such as "it drains great" is not enough. The specification should state the backing type, the drainage rate, and how the base and underlay (if used) will handle water. This is not a detail to skip over.
Seams, Nails, Edging and Power Brooming
The details that separate a professional installation from a hurried one are visible in seams, edges, and the finish work. Seams (where two pieces of turf meet) are joined with seam tape and a flexible adhesive applied to the backing. The grain of the turf (the direction the fibres face) must be aligned across the seam so the color and texture appear uniform. A visible seam, a color mismatch, or a seam that lifts or separates within the first year is a sign of poor technique or the wrong adhesive. Nails or staples hold the perimeter of the turf to the ground, spaced typically 6 to 12 inches apart and driven through the backing into the base. If nails are too far apart, the turf will lift at the edges or shift in wind or under foot traffic.
Edges are finished with bender board (a flexible metal or plastic edging), landscape timbers, or a secured perimeter so the turf does not fray or curl. On a patio or pool surround where turf meets pavers or concrete, the turf should be cut tight to the edge and the perimeter secured so water does not run under the turf and cause it to lift. On a putting green, edges are often beveled and sealed for a clean, professional look.
After the turf is laid and secured, power brooming stands the fibres upright and spreads the infill evenly across the surface. This step takes time and care, but it is essential for a natural appearance and proper performance. A turf that is laid flat and not broomed will look matted and will not drain or perform as designed. When you inspect finished work, look for tight seams with no visible gaps, edges that are clean and secure, and fibres that stand upright and feel full underfoot. These are signs of a professional installation.
What a Written Turf Spec Should Include
Before any work begins, you should receive a written specification that names every material and method the installer will use. This is your protection and your proof of what was promised. The specification should include 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 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 method and adhesive type, the edging material and method, and what cleanup and haul-off are included. The specification should also state the workmanship warranty period (typically one to three years on the installation only) and any exclusions.
If an installer cannot provide this level of detail in writing, they are either cutting corners or do not know their own process. A local, independent turf installation company names the product, the face weight, the infill, and the base depth. This is the difference between a professional installation and a crew that lays turf on bare dirt and leaves. Ask for the specification before you sign a contract, and ask questions about anything that is unclear. If you are working with an HOA or a commercial property, your specification may need to include additional details such as color match to a sample or compliance with a specific standard.
