When installing over hardscape makes sense

Concrete patios, pool decks, balconies, rooftops, and paver courtyards are strong bases that do not shift like soil. With the right underlayment and drainage, artificial grass delivers a clean, soft surface without demolition.

  • Good fit for: patios, rooftops with approved load ratings, balconies, garages, play areas, pet zones.
  • Check first: slope for water movement, door clearances, trip heights, and any waterproofing membranes.

What you need: materials checklist

  • Shock pad or foam underlayment (5 to 10 mm for comfort; thicker or rated pad for play fall zones as required)
  • Drainage mat or tile where water needs channels to escape
  • Turf adhesive rated for exterior use and compatible with concrete or pavers
  • Seam tape and adhesive for seams
  • Perimeter solution: masonry anchors with composite nailer board, edge trims, or perimeter adhesive
  • Silica sand or specialty infill as specified for the turf system
  • Weed barrier or separation fabric to prevent telegraphing on pavers
  • Tools: stiff broom, utility knife with sharp blades, notched trowel, roller, straightedge, vacuum or blower

Step by step: install over concrete or pavers

1) Evaluate and prep the surface

  • Confirm slope of at least 1 to 2 percent toward drains or edges. If water ponds, plan drainage mats or paths.
  • Clean thoroughly. Remove oils, sealers, loose paint, dust, and debris. Etch or mechanically abrade glossy areas for better adhesion if needed.
  • Fill low spots and cracks with a compatible patch or self-leveling compound. Let cure.

2) Plan drainage

  • Use a perforated shock pad or drainage tile to create airflow and water channels, especially on flat slabs or covered areas.
  • Maintain clear exit paths to scuppers, drains, or edges. Do not block weep holes.
  • On waterproofed roofs, use floating systems with drain tiles and do not penetrate membranes without manufacturer approval.

3) Prepare pavers differently

  • Vacuum joints and top the surface with a thin leveling layer if joints are deep. A separation fabric helps prevent pattern telegraphing.
  • Confirm the paver field is stable. Re-secure loose units before turf work.

4) Dry fit turf

  • Unroll turf in the same grain direction. Let it relax for 30 to 60 minutes.
  • Trim to fit with a sharp knife. Leave a small expansion gap along walls and fixed edges.

5) Seams

  • Butt factory edges carefully. Fold back, place seam tape centered, apply adhesive, then set and marry the seam with light pressure.
  • Brush fibers up and across the seam to blend. Roll lightly.

6) Perimeter attachment

  • Concrete: use perimeter adhesive compatible with the slab and turf backing. For high-traffic edges, secure a composite nailer board with masonry anchors and bond the turf to it.
  • Pavers: use edge trims or secure a nailer board at the perimeter to create a clean termination.

7) Infill and finish

  • Broom fibers upright. Distribute infill per product specs. Brush and top up for even coverage.
  • Inspect seams and edges. Remove excess adhesive. Rinse the surface.

Drainage and moisture control

  • Always give water a way out. Slope, drains, and drainage mats prevent pooling.
  • Ventilation layers reduce moisture and help the slab dry after rain.
  • Avoid trapping water against thresholds or siding. Maintain clear gaps.

Comfort, safety, and heat

  • Shock pad improves feel and reduces joint load on hardscape.
  • For play areas, use a pad or system rated to the required fall height.
  • Artificial turf can heat up in direct sun, especially over concrete. Cooling infills, shade, and light-colored surroundings help manage temperature.

Common mistakes to avoid

  • Skipping underlayment. Hard slab without pad feels harsh and shows imperfections.
  • Ignoring drainage. No exit path equals puddles and odor risk.
  • Weak seams. Use proper tape, adhesive, and alignment.
  • Wrong adhesives. Choose exterior grade products compatible with both surfaces.
  • No allowance at doors or walls. Check clearances and expansion gaps.

Maintenance and care

  • Broom or blow debris weekly. Rinse as needed.
  • For pets, use enzyme cleaners and ensure drainage paths stay open.
  • Check edges and seams seasonally. Top up infill if fibers mat down.

Specs, codes, and warranty notes

  • Confirm roof load ratings and fire requirements where applicable.
  • Follow turf, pad, and adhesive manufacturer instructions. Review warranty terms for hardscape installs.
  • Avoid penetrating waterproof membranes without written approval from the membrane manufacturer.
