Artificial grass in Laredo lives or fails beneath the surface. The infill that holds it up, the base that drains it, and the preparation work that keeps it flat and odor-free are invisible once the turf is down, but they determine whether your yard stays green and usable through our brutal summers or turns into a swampy, seamed mess within a year. This guide walks you through those hidden layers so you understand what a real installation looks like, what questions to ask, and what to expect when you call for a free estimate.
Whether you are converting a dead Bermuda lawn, building a dog run that does not smell, installing turf around a pool, or preparing a yard for a sale or move-in, the same foundation principles apply. Laredo's thin sandy-clay soil, the hard caliche layer underneath, our intense heat and occasional heavy rain all shape how we prepare and drain artificial turf here. This page is for homeowners who want to know what is happening in their yard and how to verify that the work is done right.
Turf Infill Options: Silica, Coated Sand, Zeolite and Envirofill
Infill is the granular material spread across the turf surface to weigh it down, hold the fibres upright, and protect the backing from ultraviolet light. The most common residential infill is silica sand, a basic ballast that is inexpensive and effective but visible as a light gray layer if you part the grass. Silica performs well in Laredo's heat and drains freely, making it the default choice for most yards and budgets.
Coated sand is silica that has been rounded and sometimes colored to look less obvious and feel softer underfoot. It costs more than raw silica but wears better on high-traffic areas and is gentler on bare feet and pet paws. Zeolite is a porous mineral that absorbs moisture and odors, making it popular for pet turf and dog runs where urine breakdown is a concern. It is often blended with sand rather than used alone. Antimicrobial and cooling coated infills, such as Envirofill, are engineered to inhibit bacterial growth and reduce surface temperature in full sun. These products cost more but can be worth the investment in yards where odor control or heat mitigation is a priority. Crumb rubber, made from recycled tires, is standard for sports fields and athletic courts but is rarely used in residential yards because it retains heat, breaks down over time, and is not necessary for typical home use.
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. Typically, residential turf needs between 1.5 and 3 pounds per square foot, depending on the product's pile height, face weight, and intended use. The infill serves multiple purposes: it props the fibres upright so they look full and green, it protects the backing from UV damage, it adds weight to keep the turf from shifting in wind, and it helps water drain through the mat and into the base below. Too little infill is a common shortcut taken by cheap installers trying to reduce material costs, and the result is turf that looks thin and matted within months, seams that lift, and drainage that fails because water runs across the top instead of through it.
Ask any installer to provide the infill specification in writing before work begins. The figure should be tied to the specific turf product you are choosing, not a generic range. Higher pile heights and lighter face weights typically require more infill; dense, short-pile turf may need less. Pet areas and play zones often benefit from the higher end of the range because they take more foot traffic and require better odor control. On patios and balconies, infill amount may be adjusted based on the drainage underlay and the slope. The installer should spread and power broom the infill to settle it evenly across the entire surface, not dump it and leave it in piles.
What to Put Under Artificial Grass for Drainage
Proper drainage under artificial grass starts with removing what is already there. If you have a dead or dying Bermuda lawn, the old turf and its root system must be stripped away completely. If there is existing artificial turf that is lifting, seaming, or failing, that comes out too. Once the surface is clear, the real work begins: excavation and base preparation. The goal is to create a stable, well-draining platform that slopes gently away from your house and any pool or structure so water runs off rather than pools.
After excavation, a weed barrier (typically landscape fabric) may be laid to prevent soil from mixing up into the base rock, though this step is not always necessary in Laredo's dry climate. Next comes the free-draining base layer, usually three to four inches of decomposed granite or crushed base rock, compacted firmly with a plate compactor. This is where the real drainage happens. On top of that goes an optional draining underlay or pad, which is especially useful for pet areas, play zones, and patios and pool surrounds where foot traffic is heavy or where you want extra cushioning. Finally, the turf itself is laid and secured. On hard surfaces like concrete or balconies, never glue turf flat to a slab that holds water. Instead, use a draining underlay and ensure edge drainage so water does not trap underneath and cause rot, odor, and seam failure.
Base Prep on Laredo Soil: Excavation, Base Rock and Compaction
Laredo soil is typically a thin layer of sandy-clay topsoil over a hard caliche layer (calcium-carbonate hardpan) that sits just below the surface in many yards. This caliche is impermeable and does not drain, which is why Bermuda lawns scorch and thin every summer despite occasional rain. When you prepare a base for artificial grass, you have to account for this geology. Excavation depth depends on your yard, but typically three to four inches of base material is removed and replaced with free-draining crushed rock or decomposed granite. If caliche is present and the water problem is severe, the excavation may need to go deeper, or the caliche may need to be broken up to allow water to percolate below. This is not always necessary, but if your yard has standing water after rain or if you notice poor drainage during the site visit, base preparation is the place to fix it.
The base rock must be compacted in lifts (thin layers) using a plate compactor, not just raked and left loose. Proper compaction creates a solid, level platform that will not settle or develop dips where water collects and turf sags. An uncompacted base is why you see low spots, puddles, and odor problems a few months after installation. Grading is critical too: the base should slope gently away from the house and pool so water runs off to the yard's perimeter or drainage swale. The Laredo building department should be consulted if your project involves significant grading that changes how water leaves your property, especially if you are near a right-of-way or if commercial work is involved. Before excavation, request a Texas 811 utility locate to mark public water, gas, and electric lines. Private lines like irrigation, low-voltage lighting, and pet-fence wires are not marked by 811, so ask your installer to locate those and mark them before digging.
Artificial Grass Drainage and Underlay: Perforated vs Fully Permeable
Artificial grass itself is designed to drain. Most residential turf has a backing (the layer glued to the bottom of the fibres) that is either perforated (small holes punched through) or fully permeable (allowing water to flow through the entire material). Drainage rate is measured in gallons per hour per square foot, and faster is not always better. A very fast-draining turf can allow infill to wash away in heavy rain if the base and underlay do not also drain well. A moderate drainage rate paired with a good base and underlay is more reliable. Ask your installer for the drainage specification of the turf product in writing so you know what to expect.
The real test of drainage comes in two situations: after a heavy downpour in our occasional cloudbursts, and in pet areas where urine is concentrated. A fast-draining turf still fails if the base underneath does not drain, which is why base preparation is not an afterthought. On hard surfaces like concrete, a draining underlay or pad is essential. This is a foam or rubber sheet with small holes or channels that sits between the concrete and the turf, allowing water to flow to the edges and drain away. Without it, water pools under the turf, bacteria and odor develop, and seams begin to lift. Similarly, on balconies and rooftops, edge drainage must be planned so water reaches the perimeter gutter or drain. Turf glued or stapled flat to a slab with no underlay and no edge drainage is a setup for failure.
Seams, Nails, Edging and Power Brooming
The finishing details separate a careful installation from a rushed one. Seams are the joints where two pieces of turf meet, and they are the most visible and vulnerable part of the job. A proper seam is created by aligning the grain of both pieces so the fibres run the same direction, overlapping the backing by two to three inches, and joining them with seam tape and a waterproof adhesive designed for artificial grass. The adhesive is applied to the backing, the tape is pressed down firmly, and the overlap is trimmed away once it sets. A visible seam, a seam that curls or lifts at the edges, or one where the grain does not match tells you the work was not done carefully. In pet areas and high-traffic zones, a poor seam is the first place you will see failure.
Edges and perimeter finishing are equally important. Turf must be cut tight to paving, pavers, and deck boards so there is no gap where foot traffic can roll the edge or where water can pool. The perimeter is typically secured with galvanized nails or staples spaced six to eight inches apart, or with a bender board (a flexible metal or plastic strip) screwed down to hold the edge in place. On patios and pool surrounds, the turf should be cut to follow the shape precisely so the finish looks intentional and professional. After all seaming, nailing, and edging is complete, the installer power brooms the entire surface to stand the fibres up and spread the infill evenly. This is not cosmetic: power brooming helps the turf look full, ensures infill is distributed fairly, and helps water drain through the mat instead of running across the surface.
What a Written Turf Spec Should Include
Before you hire any turf installation company, ask for a written specification that includes every detail of the work. This spec is your protection and your proof that the installer knows what they are doing. It should name the turf product by its manufacturer and model, specify the fibre type (polyethylene, nylon, or polypropylene), state the face weight in ounces per square yard, and list the pile height in inches. The backing type and drainage rate (in gallons per hour per square foot) should be included. The infill should be named and specified in pounds per square foot. The base should be described by depth (typically three to four inches), material (crushed base rock, decomposed granite, or similar), and compaction method. The spec should mention whether a weed barrier is used, how seams are joined, what edging method is used, and what cleanup and haul-off are included. Finally, it should state the workmanship warranty period, which is typically one to three years on the installation only.
A written spec is not a sales document. It is a technical agreement that holds both you and the installer accountable. It prevents misunderstandings about product quality, infill depth, base preparation, and warranty coverage. If an installer is reluctant to put these details in writing or offers only a verbal estimate, that is a red flag. Ask for references and photos of finished work, verify that the company carries a certificate of insurance naming general liability and workers' compensation, and check that they have a local Laredo address.
