Pup-Grass™ Installation Guide


  1. The area for Pup-Grass™ installation should be clearly defined and marked, if necessary.
  2. In this planning stage, it should be noted which direction the Pup-Grass™ rolls will be laid out.
  3. Always run the grain of the Pup-Grass™ against any slope, if possible.
  4. Also, note the borders of the Pup-Grass™ and determine which edging or curbing technique will be used.
  5. Be sure to allow for drainage, runoff, wet or shady areas, etc.. When laying out your yard and keep in mind the Pup-Grass™ arrives in 15' widths.


  1. Remove all grasses, sods, mulches etc. from the marked area. (Sod removal in small areas can be done with a hoe or shovel and you can use a tiller or rented sod cutter for larger areas).
  2. In-ground sprinklers may be capped or removed at this time.
  3. You may want to add an optional soil sterilent at this time. (Be sure to follow the manufacturer's directions closely with these chemicals.
  4. If you are landscaping around trees, shrubbery, flowers, light poles, utilities, etc., remember to mark around those areas and account for the Pup-Grass™ edge configuration.
  5. Remember to leave ample area uncovered around the bases of trees.


  1. Hand roller or plate tamp
  2. Shovel, Hoe, Tiller or Sod Cutter
  3. Crushed stone
  4. Vibratory or roller compactor
  5. Seam scrim or tape
  6. Commercial-grade adhesive
  7. Chalk-line or spray paint
  8. Scissors or razor knife
  9. Landscape spikes or nailer board
  10. Most, if not all of these tools can be purchased or rented at your local hardware or home improvement store.


  1. It may be necessary to compact the native soil / sub grade prior to base construction with a hand roller or plate tamp.
  2. In the case where the native soils are soft and/or saturated, it is advisable to install a geotextile to separate the soft soils from the crushed stone base. Mirafi 140N or equal should suffice.
  3. As a rule of thumb, if there is standing water, or if water comes to the surface under foot, a geotextile should be used. If applicable, consult the engineer, architect, or quarryman of record.


  1. A crushed stone base layered should be spread evenly over the prepared area.
  2. The crushed stone should be spread evenly, as smoothly as possible, and compacted to ninety percent (90%) proctor. A vibratory compactor will suffice on most small projects.
  3. The depth of this base course should be as a rule of thumb, in arid climates such as Las Vegas, Phoenix, or San Diego, two (2) inches of base course material is sufficient. In climates with more rainfall or a higher water
    table, such as Seattle, New Orleans, or Houston, six (6) inches may be necessary. The standard is four (4) inches of base course material for synthetic Pup-Grass™ surfaces.


  1. If the base course layer is not as smooth as desired, it may be necessary to add a layer of fines (stone dust, screenings, manufactured sand, etc.) to fill in the low spots or create a smooth surface. This layer should be kept to a minimum, preferably no more than two (2) inches. This layer must be compacted with a heavy roller. Do not use a vibratory compactor.


  1. Roll the synthetic Pup-Grass™ surface out on top of your constructed based, as planned. If the site requires multiple roll widths, be sure to have the grain of the fibers on each roll of Pup-Grass™ running in the same direction.
  2. If seaming is required (multiple roll widths), trim the selvedge (un-tufted edge) off one roll and lay it on the base, in the desired position.
  3. Lay the next roll adjacent to the first and overlap one edge of the adjacent roll of Pup-Grass™ on top of the trimmed edge of the first roll.
  4. With scissors or razor knife, trim the overlapped roll to match the trimmed edge of the first roll.
  5. Make all cuts as close as possible without touching.
  6. Repeat as needed for as many roll widths as the job requires.
  7. Around the borders, trim the Pup-Grass™ to match the edges.
  8. If a secured or fastened edge is desired, do not secure the edge until most of the infill is installed.


  1. Fold the adjacent trimmed edges of two rolls of Pup-Grass™ approximately two feet apart the entire length of the seam.
  2. Mark the centerline of the seam on the exposed base with a chalk line or spray paint.
  3. Roll out seam scrim or tape centered over the entire length of the seam line. Apply adhesive covering all of the seam tape from one end to the other. Depending on the type of adhesive used, you may need to allow time for
    vapors / gases to escape (flashing). Refer to the adhesive manufacturer's directions. The flashing time required may be dependent on ambient temperature and humidity.
  4. After adhesive has flashed, lay the edges of each roll of Pup-Grass™ directly onto the adhesive/tape, making sure not to bury any grass fibers into the adhesive.
  5. Be sure to add weight (i.e. sandbags or rubber bags) down the length of the freshly laid seam, or use a heavy roller along the seam length. The adhesive drying / curing time will vary with different adhesives dependent
    upon climatic conditions.


  1. In many cases, securing the edges or borders is not necessary and an optional installation activity.
  2. If an exposed edge is a concern (because of a curious animal, high activity at the border, etc.), the edges can be secured in a number of ways:
  • Landscape spikes.

Simply hammer landscape spikes, timber spikes, sod staples, etc. into the edge at desired intervals. Afterwards, more edge trimming may be necessary.

  • Nailer Board.

When installed next to a concrete or asphalt curb, a nailer board / synthetic lumber can be installed by nailing the board to the curb with concrete nails. The Pup-Grass™ can then be nailed into the top of the installed nailer board with a landscape nail. Afterward, more edge trimming of the Pup- Grass™ may be necessary.

  • Buried Edges.

Excavate a narrow trench around the border, deep enough to bury the exposed edge of the Pup- Grass™. Tuck the Pup-Grass™'s edge into the trench (additional trimming of excess Pup-Grass™ may be necessary). Backfill the excavated soil against the buried Pup-Grass™, and compact. The edge can then be hidden with mulch, straw, rock, etc.

  • Rinse/flush the entire Pup-Grass™ system with a water hose / sprinkler system to control odor and push urine through the drainage system. This should be done on a regular basis
  • Use a leaf blower to remove debris (leaves, sticks, etc)
  • An anti-microbial spray can be used regularly to help combat odor and bacteria (e.g. Bacshield anti-microbial topical spray). The Pup-Grass™ fibers themselves have anti-microbial properties but a topical spray will help re-enforce odor and bacteria control giving the owner piece of mind.
  • Clean up spills as they occur or are found. Blot up spill with towels. Clean with water and mild detergent (a small amount of bleach if necessary) and flush with clean water. Blot with dry towels to remove moisture.
  • Broom regularly with a stiff shop broom to revitalize the fiber (and keep the infill level, if applicable). Apply necessary infill, if necessary, with drop spreader and broom to level.
  • Most cleaning agents will not harm the fiber. Check with the manufacturer prior to using any solvents as some do damage the backing.
