Artificial grass installed on a poor base fails in Tallahassee's heat and rain. This guide walks you through the hidden work that makes turf last: infill selection, base preparation, drainage design, and the finishing details that separate a real installation from a shortcut. Whether your yard sits on red clay, slopes toward a low corner, or drains into a pool surround, the ground underneath the turf matters as much as the turf itself.
This is a reference for homeowners in Tallahassee and surrounding areas who want to understand what goes into the ground before a single blade of synthetic turf is laid, and what to ask for in writing before work begins. You will finish it knowing what infill does, why base compaction prevents puddles and odor, and what a complete written specification looks like.
Turf Infill Options: Silica, Coated Sand, Zeolite and Envirofill
Infill is the material spread over and brushed into the turf fibres after installation. Its job is to prop the blades upright, protect the backing from UV damage, add weight so the turf stays in place, and help water drain through. The type of infill you choose depends on the use of the yard and the climate.
Silica sand is the baseline infill on most residential turf. It is inexpensive, widely available, and does the job of ballasting and drainage. The drawback is that it can compact over time and does nothing to reduce odor in pet areas. Coated sand is silica sand treated with a rounded coating that makes it gentler underfoot and can be coloured to complement the turf blade. Coated infills are more comfortable for play areas and pet turf and dog run installations. Zeolite is a naturally porous mineral that absorbs and neutralizes ammonia and other odor compounds, making it a popular choice for dog areas and yards where odor control matters.
Antimicrobial and cooling coated infills are engineered to reduce bacterial growth and lower the surface temperature of the turf in direct sun. Products such as Envirofill are examples of these specialty infills. They cost more than silica or coated sand but can make a real difference in a yard where dogs spend time or where heat is a concern. Crumb rubber (recycled tire rubber) is used on sports fields and athletic courts because it provides cushioning and impact absorption, but it is not recommended for residential yards or pet areas due to heat retention and odor concerns in Tallahassee's climate.
How Much Infill Artificial Grass Needs, and Why
Infill depth is specified in pounds per square foot, and it is one of the most common places where cheap installations cut corners. A typical residential turf might call for 2 to 4 pounds per square foot, depending on the pile height and backing type of the product. Pet turf and play areas often need 3 to 5 pounds per square foot to keep the fibres standing upright and to cushion movement. The heavier the infill load, the more stable and durable the turf, but also the higher the material cost.
Infill serves multiple purposes: it holds the fibres erect so they do not mat down under foot traffic, it shields the backing from ultraviolet light (which degrades latex and polypropylene), it adds weight that prevents the turf from shifting in wind or under water pressure, and it helps water pass through the pile and into the base below. Too little infill is a red flag. If a base layer of infill is missing or spread too thin, the turf will flatten, the backing will degrade faster, and drainage will suffer. Always ask your installer for the infill specification in writing, including the type and the pounds per square foot. This is not a detail to skip over.
What to Put Under Artificial Grass for Drainage
The path from soil to finished turf runs through several layers, each with a purpose. Start by removing the existing lawn, dead sod, or old turf and as much of the root mat as practical. On a yard with compacted clay or poor drainage, excavate 2 to 4 inches to expose fresh soil and improve the grade. Use a weed barrier (landscape fabric) in areas where weeds are likely to push up through the base, particularly around the edges and in shaded corners where moisture lingers. Weed barriers slow but do not stop water, so they do not interfere with drainage when used correctly.
Next, install a free-draining base material. In Tallahassee, this is typically decomposed granite or crushed limestone base rock, spread in lifts (layers) and compacted firmly with a plate compactor. Compact each lift to 95 percent of standard density, which means the base will not settle or shift after the turf is laid. For patios, balconies, and hard surfaces, or for pet areas where cushioning and drainage are critical, add an optional draining underlay or shock pad on top of the compacted base before the turf. This pad absorbs impact, keeps the turf cooler, and helps water move sideways and down. On concrete or a sealed patio, never glue turf flat to the slab; instead, use a permeable underlay with edge drainage so water does not pool underneath. Finally, lay the turf with seams and edges secured, and brush in the infill.
Base Prep on Tallahassee Soil: Excavation, Base Rock and Compaction
Tallahassee sits on rolling red clay hills with patches of sand and hardpan, and the soil type under your yard determines how much base preparation is needed. Red clay drains poorly and holds water, especially on a slope or in a low corner of the yard. If your existing lawn thins out, puddles after rain, or turns to mud in your dog area, the soil is the problem, and the base has to be built to fix it. This means excavating down to solid ground, removing roots and organic material, and grading the excavation to slope away from the house and away from any pool or structure. The goal is to shed water downhill, not trap it in a low spot.
Lay 3 to 4 inches of compacted base material (decomposed granite or crushed base rock) over the graded excavation. Compact it in lifts with a plate compactor, pushing each layer until it is firm and will not shift under foot. An uncompacted base is the fastest path to failure: the turf will settle unevenly, creating dips that puddle and hold water, and the infill will work its way down into soft soil, leaving the surface thin and prone to matting. In areas of Tallahassee with true water problems (a yard that stays wet, a low point that floods, or a slope that sheds water across the property), drainage must be addressed before the turf is laid. If the site cannot be graded and drained to shed water reliably, the job is not a good fit for artificial turf, and we will say so. A properly prepared base takes time and equipment, but it is the foundation of a turf installation that lasts.
Artificial Grass Drainage and Underlay: Perforated vs Fully Permeable
Water has to move through the turf and through the base, and the speed at which it does so is the measure of a drainage system. Turf backing is either perforated (with small holes punched through it) or fully permeable (woven or knitted so water passes through the material itself). Perforated backing is common and adequate for most residential yards. Fully permeable backing drains faster and is preferred for pet areas, play zones, and pool surrounds, where standing water or urine saturation is a risk. Drainage rate is measured in gallons per hour per square foot (gal/hr/sf), and a faster rate is better. Turf with a drainage rate of 30 to 50 gal/hr/sf is considered good; rates above 60 gal/hr/sf are excellent and are typical of high-end residential and pet-specific products.
However, fast-draining turf installed on a slow-draining base is a contradiction. Water will back up at the interface between the turf and the base, creating wet spots, odor in pet areas, and long drying times after rain. This is why base preparation and turf drainage work together. For hard surfaces such as concrete, balconies, or patios, an underlay or shock pad is essential. It sits between the turf and the concrete, allows water to drain to the edges, and keeps the turf from sitting in standing water. On a putting green or a sports surface, drainage rate is even more critical because water pooling ruins playability. Ask your installer for the drainage specification of the turf and the base material, and insist on it in writing.
Seams, Nails, Edging and Power Brooming
The finishing details separate a professional installation from a shortcut job. Seams are the joints where two pieces of turf meet, and they must be sealed to prevent water from running underneath, to keep the fibres from separating, and to hide the joint so it is not visible in daylight. A proper seam is joined with seam tape (a fabric strip) and a flexible waterproof adhesive applied to both sides of the tape and pressed into the backing. The grain of the turf (the direction the fibres lean) must be aligned at the seam so the colour and texture match. A visible seam, a seam that peels up at the edges, or a seam that water runs under is a sign of poor workmanship.
Nails and staples hold the turf to the base at the perimeter and at seams. They must be spaced correctly (typically 6 to 8 inches apart) and driven so the head sits flush with the backing without tearing it. Edging is the perimeter detail: the turf is cut to fit the yard boundary and secured with bender board (a flexible metal or plastic edge), landscape edging, or by tucking it under existing hardscape. Edges must be tight and clean so the backing does not show and water cannot get underneath. On a patio or pool surround, the turf is cut tight to the pavers so water drains off the turf and onto the deck, not under it. Finally, power brooming is the last step: a mechanical broom is run over the turf to stand the fibres upright, spread the infill evenly, and give the surface a finished, uniform appearance. A turf that has not been power broomed will look flat and matted.
What a Written Turf Spec Should Include
Before work begins, ask your turf installer for a written specification that includes every detail of the installation. This is not optional and is not a sales document; it is a contract between you and the installer that protects both parties. The spec should name the turf product and fibre type (polyethylene, polypropylene, or nylon), the face weight (the weight of fibre per square yard, typically 50 to 80 ounces), the pile height (the length of the blade, typically 1.25 to 2 inches for residential turf), the backing type and drainage rate (perforated or permeable, and gallons per hour per square foot), and the infill type and pounds per square foot.
The spec should also detail the base preparation: the depth of excavation, the type and depth of base material (e.g., 3 inches of compacted crushed limestone), the compaction standard (95 percent of standard density), whether a weed barrier is used, and whether an underlay or pad is included. Include the seam method (seam tape and adhesive, with grain alignment), edging type (bender board, metal edge, or tucking method), whether the perimeter will be nailed or stapled, and whether power brooming is included. Finally, the spec should state what cleanup and haul-off are included (old sod, excavated material, debris) and the workmanship warranty period (typically one to three years on the installation itself).
