A professionally built backyard putting green is about much more than the artificial grass you see on the surface.
The foundation, drainage, quality materials and professional installation all work together to create a putting green that delivers a smooth, consistent ball roll and performs reliably for years to come.
At Unreal Lawns, every putting green is carefully designed to suit your property, ensuring it not only looks great but also provides an enjoyable putting experience with minimal maintenance.
Why Professional Installation Matters
A tour-quality practice green requires precision civil engineering beneath the turf. At Unreal Lawns, we build every residential putting green using a structured, multi-layer base process: site excavation, sub-grade compaction, installing a free-draining compacted aggregate metal base, laying precision TrueRoll Hybrid PE/PP turf, and applying calibrated silica sand infill. For short-game target greens designed to take full chip shots, we also integrate an optional SafeBase 10mm High-Density Shockpad beneath the turf to absorb impact while keeping foot stance firm.
Every Backyard Is Different
No two backyards are exactly the same.
Factors such as available space, existing landscaping, drainage and intended use all influence the final design.
Whether you’re looking for a compact practice green or a larger feature with multiple holes and a surrounding fringe, every project is individually planned to complement your outdoor space.
Step-by-Step: Base Preparation & Drainage Engineering
The quality of the finished putting surface depends on what lies beneath it.
The performance of your putting surface relies entirely on what sits beneath the green. We do not use non-standard methods like laser leveling for residential backyards; instead, our team follows a strict civil preparation process:
-
1. Excavation & Sub-Grade Compaction: We excavate the natural topsoil down to a stable clay or sub-soil layer, establishing sub-grade drainage contours to direct groundwater away from your lawn or home.
-
2. Geotextile Separation Membrane: A heavy-duty geotextile layer is laid over the raw sub-grade to prevent native soil from contaminating the base aggregate while allowing water to pass freely.
-
3. Compacted Aggregate Metal Base: We lay and mechanically compact GAP20/GAP7 aggregate metal in layers using heavy plate compactors. This creates a rock-solid, stable foundation that will not sink or shift under foot traffic.
-
4. Sub-Surface Drainage Pathways: Integrated sub-base drainage channels ensure heavy Kiwi downpours pass straight through the system, eliminating surface waterlogging and letting you practice immediately after rain.
-
5. Optional SafeBase 10mm Shockpad: For clients wanting a full short-game practice setup, our SafeBase 10mm high-density foam shockpad is installed over the compacted metal base. It provides realistic impact absorption for pitch shots from 10 to 30 metres out without introducing foot-sinking during putts.
TrueRoll Hybrid Surface Installation & Infill Calibration
-
TrueRoll Hybrid Dual-Yarn Turf: Laid flat and seam-matched with precision joining tape and commercial-grade adhesives. The PE/PP dual-yarn weave eliminates directional grain drift completely, guaranteeing a true, multi-directional roll.
-
Rounded Silica Sand Infill: We apply kiln-dried, purpose-designed rounded silica sand infill using calibrated drop spreaders. The sand is power-brushed deep into the fibers to hold the turf upright, regulate stimp speed, and ballast the green against movement.
Designed to Complement Your Landscape
A backyard putting green should feel like a natural part of your outdoor living area.
Many homeowners choose to include:
- Gentle contours
- Fringe grass
- Garden edging
- Decorative planting
- Pathways
- Outdoor entertaining areas
Thoughtful design creates a putting green that is both functional and visually appealing.
Built for Long-Term Enjoyment
A professionally installed putting green offers years of low-maintenance enjoyment.
Unlike natural grass, there is:
- No mowing
- No fertilising
- No irrigation
- No muddy patches
Routine care generally involves occasional brushing, removing leaves and debris, and checking sand levels over time to maintain putting performance.
Why Experience Makes a Difference
Installing a putting green requires careful planning and attention to detail.
Professional installation helps ensure:
- Smooth surface levels
- Reliable drainage
- Secure edging
- Quality finishing
- Long-term durability
Choosing an experienced installer gives you confidence that your putting green has been built to perform from the ground up.

Frequently Asked Questions
Why is a compacted aggregate metal base better than standard topsoil?
Natural topsoil expands, contracts, and holds moisture, which causes uneven settling and surface lumps over time. A properly compacted aggregate metal base provides a rock-solid, free-draining foundation that maintains true surface levels and handles heavy Kiwi rain without shifting.
Do you use laser leveling for residential putting greens?
No. Laser leveling is designed for large, flat commercial fields. Residential backyard greens require organic contours, custom undulations, and positive fall slopes engineered by hand to ensure natural drainage and challenging practice breaks.
What is the optional SafeBase 10mm Shockpad upgrade?
SafeBase is a high-density foam shockpad installed between the compacted aggregate base and the turf. If you plan to pitch or chip onto your green from 10 to 30 metres out, SafeBase absorbs the ball's energy so incoming shots bite and hold like natural grass—without making your putting stance soft or spongy.
How realistic is the ball roll on TrueRoll Hybrid turf?
Highly realistic. Standard synthetic greens use single-yarn plastic that lays down over time, creating a directional "grain" that pulls putts off line. Our TrueRoll Hybrid PE/PP dual-yarn blend eliminates grain drift completely, delivering a smooth, multi-directional roll at consistent tour speeds.
How long does a professional installation take?
Most residential backyard installations take between 2 to 4 days from start to finish. This depends on site access, excavation volume, and the complexity of your custom contours, cup placements, and fringe grass layout.
How does the green drain after heavy rain?
Water passes directly through the turf backing, SafeBase shockpad (if installed), and into the free-draining compacted metal base below. This sub-surface drainage system shifts water away instantly, preventing surface pooling and leaving the green ready for practice as soon as the rain stops.
