Artificial grass installation in Grand Junction depends on what lies beneath the turf as much as the turf itself. The region's alkaline clay soil, seasonal freeze-thaw cycles, and the contrast between dry summers and spring runoff create specific challenges for base preparation, drainage, and infill selection. A turf installation that ignores these conditions will settle, puddle, smell, or fail at the seams within months. This guide walks homeowners through infill types, base excavation and compaction, drainage design, and the finishing details that separate a durable installation from a temporary one.
Whether you are converting a dead lawn, building a dog run that stays dry and odor-free, preparing a patio or pool surround, or installing turf on a commercial property, understanding the layers beneath the surface will help you ask the right questions of any installer and recognize the difference between a proper job and a shortcut. We have included the specifications you should demand in writing before work begins.
Turf Infill Options: Silica, Coated Sand, Zeolite and Envirofill
Infill is the granular material spread across the turf after installation. It serves multiple purposes: it props the synthetic fibres upright so they look and feel natural, protects the turf backing from UV damage, adds weight to keep the turf from shifting, and helps the drainage system work by filling the spaces between blades. The type and amount of infill you choose depends on how the turf will be used and what problems you want to solve.
Silica sand is the most common and least expensive infill. It is a fine, sharp-edged mineral that holds its place well and provides good drainage. Silica works for most residential yards and is the baseline against which other infills are compared. Coated sand takes silica a step further by rounding the grains and often adding color or a polymer coating. Rounded grains are gentler on the turf fibres and feel softer underfoot, which matters for play areas, patios, and yards where barefoot comfort is a priority. Zeolite is a porous mineral that naturally absorbs and neutralizes ammonia and other odors. It is commonly blended with sand in pet turf applications because it reduces the smell of urine without requiring chemical treatments. Antimicrobial and cooling coated infills, such as products sold under names like Envirofill, combine a mineral base with a polymer or silica coating that inhibits bacterial growth and may reduce surface temperature slightly. These products cost more than plain sand but can be valuable in high-traffic pet areas or where odor control is a priority.
Crumb rubber (recycled tire material) is sometimes offered as an infill, but it is designed for sports fields and playgrounds where impact absorption is the main goal, not for residential yards. Crumb rubber retains heat, breaks down over time, and is not recommended for pet areas or general residential use. When evaluating infill options, ask your installer to specify the product, grain size, and the amount (in pounds per square foot) in writing before installation begins.
How Much Infill Artificial Grass Needs, and Why
Infill is measured in pounds per square foot, and the amount matters far more than most homeowners realize. A properly installed turf will typically require between 12 and 20 pounds of infill per square foot, depending on the turf product, pile height, and intended use. The infill holds the synthetic fibres upright and prevents them from matting down. It also protects the backing material from direct sunlight, which can degrade polyethylene and polyurethane over time. Without enough infill, the turf will look flat and worn within a season, the backing will deteriorate faster, and the drainage system will not perform as designed.
Specifying too little infill is one of the most common shortcuts in cheap installations. A crew working quickly might spread only 8 to 10 pounds per square foot, which saves time and material cost but leaves the turf undersupported and vulnerable. The homeowner may not notice the problem until months later, when seams begin to lift, fibres start to fray, or puddles form because the turf is no longer sitting at the right height. The correct amount depends on the specific turf product you choose, so ask your installer to provide this figure in writing as part of your specification. Different products have different face weights and pile heights, and the infill amount should be matched to those properties. Do not accept a vague assurance that "we use plenty of infill." Get the number in writing.
What to Put Under Artificial Grass for Drainage
The path to proper drainage begins long before the turf is laid. Start by removing the existing lawn or old turf completely, including roots and thatch. Old roots left in place will decompose unevenly, creating soft spots and settling. Once the surface is cleared, excavate to a depth that allows for a stable base layer (typically 3 to 4 inches of compacted material). The goal is to create a firm, level or slightly sloped foundation that will not shift or settle after installation.
After excavation, lay a weed barrier (usually a non-woven geotextile fabric) to prevent soil and weeds from working up through the base layer and into the turf. The weed barrier allows water to drain through while blocking plant growth. Next, install a free-draining base material such as decomposed granite or crushed base rock. This material should be spread in lifts (layers) of 2 inches or less and compacted firmly with a plate compactor after each lift. Proper compaction is essential: an uncompacted base will settle over time, creating dips and puddles that trap water and cause odor problems. Once the base is compacted and level, an optional draining underlay or pad can be installed. Underlays are particularly valuable under pet turf, in play areas, and on patios because they add cushioning, improve drainage, and reduce odor.
For hard surfaces such as concrete or balconies, the approach is different. Turf should never be glued flat to a concrete slab, because water will be trapped beneath it and will not drain. Instead, install a draining underlay or pad with edge drainage channels that allow water to run off to a perimeter drain or grade. This keeps the turf dry and prevents the backing from breaking down. Always ensure that the finished surface slopes gently away from the house and any pools or structures, so water does not pool against foundations or walls.
Base Prep on Grand Junction Soil: Excavation, Base Rock and Compaction
Grand Junction's soil presents specific challenges for artificial grass installation. The region's alkaline adobe clay becomes rock-hard when dry and slick and unstable when wet. Left undisturbed, clay does not drain well and will cause water to pond under the turf. Proper base preparation begins with excavation deep enough to remove the native clay and replace it with material that drains freely. In most residential yards in Grand Junction, this means excavating 3 to 4 inches and replacing the clay with decomposed granite or crushed base rock (also called crusher run or compacted aggregate).
The excavated material should be graded with a slight slope away from the house, the pool, and any other structures. A fall of 1 to 2 percent (roughly 1 inch per 4 to 6 feet) is enough to direct water away and prevent ponding. The base rock is then spread in lifts of no more than 2 inches and compacted firmly with a plate compactor after each lift. This is not optional work: an uncompacted base will settle unevenly, creating low spots where water collects and where odor and algae problems develop. Uneven settling also causes seams to separate and the turf to shift under foot traffic.
If the yard has a history of water problems, poor drainage, or standing water after rain or irrigation, these issues must be addressed before turf installation. A base layer alone may not be enough if the native soil underneath has poor percolation or if the site is in a low spot on the property. In those cases, the drainage problem should be solved first (by regrading, installing a French drain, or other means) or the job should not proceed. We will always recommend that you consult the Grand Junction building department if significant grading or drainage work is planned, as some changes may require permits or may affect neighbors' drainage rights.
Artificial Grass Drainage and Underlay: Perforated vs Fully Permeable
Drainage design for artificial grass involves two separate systems working together: the turf's permeability and the base layer's ability to accept and move water. The turf itself has either a perforated backing or a fully permeable backing. A perforated backing has small holes punched through it to allow water to drain through to the base layer. A fully permeable backing is made of a porous material (such as polyurethane or a specialized fabric) that allows water to pass through the entire surface without holes. Fully permeable backings typically offer faster drainage rates and are less prone to clogging with fine sediment or algae over time.
Drainage rate is specified in gallons per hour per square foot (GPH per sq ft). A fast-draining turf might be rated at 60 GPH per sq ft or higher, meaning it can handle heavy rainfall or irrigation without pooling. However, a turf with excellent drainage will still fail if the base layer beneath it cannot accept and move water away. This is why base preparation and compaction are critical. A properly compacted base of decomposed granite or crushed rock will drain quickly and keep water from accumulating under the turf. For pet areas, patios, and play spaces where heavy water use or frequent rain is a concern, an additional draining underlay or pad can be installed between the base and the turf. These underlays are perforated or porous materials that add a cushioning layer while maintaining drainage and reducing odor. On concrete or other hard surfaces, an underlay with edge drainage channels is essential to prevent water from being trapped between the turf and the slab.
When evaluating a turf product and installation plan, ask your installer for the drainage rate of the turf and a clear explanation of how water will move through the base layer and away from the site. Do not assume that a pretty turf specification will work on your property without a drainage plan. If your yard tends to hold water or if you have a history of wet spots, discuss this with your installer before work begins and ensure that the base design accounts for it.
Seams, Nails, Edging and Power Brooming
The quality of an artificial grass installation is often revealed in the details that most homeowners never think to inspect: how seams are joined, how edges are secured, and how the finished surface is prepared. These details determine whether the turf will hold together under foot traffic, weather, and the freeze-thaw cycles that Grand Junction experiences.
Seams are the joints where two pieces of turf meet. A proper seam is created by aligning the grain direction of the turf (the direction the fibres naturally lean), placing a seam tape under the joint, and applying a flexible polyurethane adhesive to bond the tape to the backing of both pieces. The seam should be tight, with no gap visible between the two pieces. A visible seam, a seam that feels loose underfoot, or a seam that is lifting at the edges is a sign of poor workmanship. Seams can fail if the grain is misaligned, if the tape is not wide enough, if the adhesive is not applied correctly, or if the base underneath is unstable or settling.
Edging and perimeter work is equally important. The turf must be secured around its perimeter with nails or staples at the correct spacing (typically every 6 to 8 inches) so that foot traffic and weather do not cause the edges to curl or lift. Edges should be finished with a clean cut along bender board, paver edges, or other permanent structures. Turf cut tight to pavers and cool decks prevents tripping hazards and water from pooling at the edge. Power brooming is the final step: the turf is brushed with a power broom to stand the fibres upright, spread the infill evenly, and give the surface a finished appearance. Without power brooming, the turf will look matted and uneven, and the infill will be unevenly distributed.
What a Written Turf Spec Should Include
Before any turf installation begins, you should receive a written specification that details every material and method your installer will use. This specification is your protection and your reference point if problems arise. A complete spec should include the following items, each with a specific product name or value, not a vague description.
Turf specifications: the turf product name and manufacturer, the fibre type (polyethylene, polypropylene, or nylon), the face weight in ounces per square yard, the pile height in inches, the backing type (perforated or fully permeable), and the drainage rate in gallons per hour per square foot. Infill specifications: the infill type (silica sand, coated sand, zeolite, or other), the amount in pounds per square foot, and any special properties (antimicrobial, cooling, or odor-control coatings). Base specifications: the base material (decomposed granite, crushed rock, or other), the depth in inches, the compaction method, and the weed barrier type. Installation details: the seam method (seam tape and adhesive, with grain alignment), the nail or staple spacing, the edge finishing method (bender board, paver edge, or other), and whether power brooming is included. Cleanup and removal: what happens to the old lawn or turf, and whether the installer will haul away debris or leave it for you. Warranty: the workmanship warranty period (typically one to three years on the installation only, not the turf itself).
Do not accept a quote that lists only "artificial grass installation" and a price per square foot without these details. Every turf product is different, and the base preparation and infill amount should be matched to the product and your site conditions.
