Artificial grass installation looks simple from the street, but what happens beneath the surface determines whether your turf drains properly, stays in place, resists odor, and lasts. This guide walks you through the materials and techniques that separate a durable installation from one that puddles, smells, lifts at the seams, or fails within a few years. Whether you are installing residential artificial grass, a pet turf area, or turf around a pool or patio, understanding infill, base preparation, and drainage will help you ask the right questions and verify that the work meets the specifications you have agreed to in writing.
Palm Bay's sandy soil and high water table mean that most yards puddle after the almost-daily summer thunderstorms, and poor drainage under turf becomes a breeding ground for odor and mold. This guide is written for homeowners in Palm Bay and the surrounding areas who want to know what goes into a turf installation that actually works in our climate, and what to look for when you hire a turf installation company.
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 grass fibres upright so they look and feel natural, protects the backing from ultraviolet light, adds weight to keep the turf from shifting, and helps water drain through the system. The most common infill is silica sand, a basic mineral ballast that is inexpensive and effective. Silica sand is angular and can feel coarse underfoot, especially in high heat. Coated sand improves on this by rounding the grains and sometimes adding colour or a polymer coating that reduces dust and heat retention. Both silica and coated sand are stable, long-lasting and suitable for most residential yards.
Zeolite is a porous mineral that absorbs and neutralizes odors, making it popular for pet turf and dog runs. It does not replace regular cleaning but works alongside it to reduce ammonia smell. Antimicrobial and cooling coated infills, such as Envirofill, combine a coated sand base with additives designed to inhibit bacteria growth and lower surface temperature. These products cost more than basic sand but are worth considering in high-use pet areas or where heat is a concern. Crumb rubber (recycled tire material) is primarily used in sports fields and playgrounds where impact absorption is the goal; it is not typical for residential yards. Your turf spec should name the infill type and the amount in pounds per square foot so you know exactly what is being installed.
How Much Infill Artificial Grass Needs, and Why
Infill is measured in pounds per square foot (psf) and is one of the most commonly overlooked specifications in cheap installations. A typical residential turf might call for 2 to 4 pounds per square foot, while pet turf and high-traffic areas may need 3 to 5 psf or more. The exact amount depends on the pile height, fibre density, and intended use of the turf. Infill that is too light fails to prop the fibres upright, leaving the turf looking flat and matted. It also exposes more of the backing to UV damage, shortening the life of the product. In heavy rain or pet use, inadequate infill allows the backing to move and fibres to separate, creating visible wear patterns and accelerating failure.
Many cut-rate installers under-fill to save money and time, banking on the fact that most homeowners do not know what to ask for. The correct amount should be specified in writing before work begins, and you should ask to see the calculation based on the turf product and the square footage of your yard. Infill is spread by hand or machine and then power broomed to settle it evenly. If you are unsure whether your turf has the right amount, ask your installer for the figure in writing as part of your spec sheet, and do not accept vague promises like "industry standard" without a number.
What to Put Under Artificial Grass for Drainage
The layers under artificial grass are as important as the turf itself, especially in Palm Bay where the sandy soil drains quickly in some spots and holds water in others. The process begins with removal of the existing lawn or old turf. If you have Bahia or Floratam grass, it must be stripped away and hauled off, along with the root layer. Old artificial turf is removed down to the base, and any roots or debris are cleared. Next comes excavation and grading. The ground is dug out to the depth required by your turf spec (typically 3 to 4 inches), and the surface is sloped gently away from your house and any pool or patio so water does not collect. A weed barrier (landscape fabric) is laid to prevent grass and weeds from growing up through the turf; this is standard for residential yards and essential if your yard has a history of persistent weeds.
The base layer is then installed: typically 3 to 4 inches of decomposed granite or crushed base rock, compacted firmly in lifts (layers) with a plate compactor. Proper compaction is critical. An uncompacted base shifts under foot traffic and turf seams, creating dips and puddles that trap water and cause odor problems. For pet areas, patios and balconies, and playgrounds, an optional draining underlay or pad is installed on top of the compacted base. This adds cushioning, improves drainage, and reduces odor by keeping liquids moving through the system. On hard surfaces like concrete or a balcony slab, turf is never glued flat directly to the concrete; instead, a draining pad or underlay is laid first, and edge drainage is installed to prevent water from pooling underneath. This layered approach is what separates durable work from installations that fail within a year or two.
Base Prep on Palm Bay Soil: Excavation, Base Rock and Compaction
Palm Bay's soil is predominantly grey sand over a high water table, with pockets of clay and hardpan that hold water after heavy rain. This soil type is both a challenge and the reason proper base preparation is non-negotiable. When you excavate for artificial turf, you are removing the top 3 to 4 inches of existing lawn and soil and replacing it with a free-draining base of decomposed granite or crushed base rock. This material is chosen because it compacts firmly, allows water to percolate downward, and does not turn to mud in our frequent summer storms. The excavation is graded with a gentle slope away from your house and any pool or patio enclosure, ensuring that water runs off rather than pooling. This slope is subtle (typically 1 to 2 percent fall) and is not visible to the eye, but it is essential in a climate where standing water breeds odor and mold.
The base material is then compacted in lifts using a plate compactor or similar equipment. Compaction is done in 1 to 2 inch layers, with each layer compressed firmly before the next is added. This creates a stable, unyielding surface that does not settle or shift under the weight of foot traffic or the turf itself. An uncompacted base is the most common shortcut of poor-quality work. It looks fine on the day of installation, but within weeks or months, the base settles unevenly, creating dips and soft spots where water collects. These puddles trap odor, especially in pet areas, and the movement of the base causes seams to separate and fibres to wear prematurely. If your yard has a genuine drainage problem (water that stands for days after rain, or a history of flooding), base preparation alone may not solve it. In those cases, we address the drainage issue first or decline the project, because no turf installation can succeed on a base that does not drain.
Artificial Grass Drainage and Underlay: Perforated vs Fully Permeable
Artificial grass is designed to drain water through the turf and down through the base, not to shed water like a roof. The turf backing determines how fast water moves through: perforated backing has small holes punched through it, allowing water to flow at a controlled rate, typically 4 to 8 gallons per hour per square foot (gph/sf). Fully permeable backing allows faster drainage, often 15 to 20 gph/sf or more, and is preferred for pet areas and applications where heavy water flow is expected. The drainage rate should be listed in your written spec. However, a fast-draining turf means nothing if the base underneath does not drain. Water that reaches the base must percolate downward into the soil or be directed away. This is why base preparation and compaction are so critical. A poorly compacted base or one with clay pockets will hold water, and that water will eventually surface at the lowest point in your yard, creating puddles and odor.
For hard surfaces such as concrete, pavers, or a balcony slab, an underlay or drainage pad is installed between the turf and the hard surface. This pad allows water to flow laterally and drain away at the edges rather than pooling directly under the turf. On a roof or balcony, edge drainage must be installed to guide water away from the structure. The combination of the right turf backing, a properly compacted base, and correct grading is what allows Palm Bay yards to shed water after our intense summer thunderstorms without ponding or odor. If you are considering turf for an area that currently stays wet, ask your installer how drainage will be improved as part of the project. If the answer is vague or relies only on the turf itself, that is a red flag.
Seams, Nails, Edging and Power Brooming
The finishing details of a turf installation reveal whether the work was done by someone who understands the product or by someone laying turf as quickly as possible. Seams are where two pieces of turf meet, and they must be handled carefully. The two pieces are aligned so the grain of the fibres runs the same direction, overlapped slightly, and joined with seam tape and adhesive applied to the backing. A properly sealed seam is nearly invisible and holds firmly. A visible seam, or one that lifts at the edges, tells you the tape was applied carelessly or the adhesive was not given time to cure. Nails or staples secure the turf around the perimeter and at seams, spaced at the correct interval (typically 6 to 12 inches, depending on the product and site conditions). Nails that are too far apart allow the turf to shift; nails that are too close together can bunch the backing and create wrinkles.
Edging is the perimeter of the turf, and it must be clean and secure. Common options include bender board (a flexible metal or plastic strip) secured with nails, or a secured perimeter edge that holds the turf tight. Where turf meets pavers or a pool deck, it is cut tight with a sharp utility knife so water does not pool in a gap. Power brooming is the final step: the entire surface is swept with a power broom to stand the fibres upright, settle the infill evenly, and remove any dust or debris. A properly broomed turf looks full and natural; an un-broomed turf looks flat and matted. These finishing details take time and skill, which is why they are often skipped on low-cost jobs. When you inspect work, look for tight seams, secure edges, and fibres that stand up naturally. These tell you the installer understood the job and took care to do it right.
What a Written Turf Spec Should Include
Before any work begins, you should have a written specification that names every material and method that will be used on your yard. This spec protects you by making clear what you are paying for and what the installer has committed to deliver. A complete spec includes: the turf product name and fibre type (polyethylene, nylon, or polypropylene); the face weight (total weight of the fibres per square yard); the pile height (length of the grass blades); the backing type and drainage rate (perforated or fully permeable, measured in gallons per hour per square foot); the infill type and amount in pounds per square foot; the base depth, material and compaction method (for example, 3.5 inches of crushed base rock, compacted in lifts); whether a weed barrier is included; the seam method (tape and adhesive with grain alignment); the edging type (bender board, perimeter edge, or other); cleanup and haul-off of old turf and debris; and the workmanship warranty period (typically one to three years on the installation). The spec should also note any site-specific details, such as grading away from the house, drainage improvements, or HOA requirements.
Ask your installer to provide this spec in writing before you sign a contract or make a deposit. If they cannot or will not put the details in writing, that is a warning sign. The spec is your reference point if there is ever a dispute about what was installed, and it is the basis for any warranty claim. Once the work is complete, keep the spec with your records. For residential installations, commercial projects, and specialized applications like putting greens or sports turf, the spec is even more important because the performance demands are higher.
