20mm Artificial Grass: The Versatile Mid-Pile Choice for Gardens & Outdoor Spaces

Looking for a balance between a natural look and everyday practicality? Our 20mm artificial grass collection hits the sweet spot. With a mid-length pile that's soft underfoot yet easy to maintain, it's one of our most popular choices for homeowners and businesses across the UK.

At Grass Cash & Carry, we stock a carefully selected range of 20mm artificial grass designed to suit a wide variety of outdoor spaces — from family gardens and patios to commercial landscaping projects. Enjoy a lush, green lawn all year round without the mowing, watering, or feeding.

Why Choose 20mm Artificial Grass?

Our 20mm artificial grass range offers the ideal combination of aesthetics, comfort, and durability. It's a great fit for:

  • Family Gardens: Soft enough for children to play on, yet robust enough to handle regular use.
  • Patios & Decking: Adds a natural, welcoming feel to hard outdoor surfaces without the hassle of real turf.
  • Front Gardens: A neat, tidy appearance that enhances kerb appeal with zero upkeep.
  • Commercial Spaces: Ideal for offices, retail displays, and hospitality venues looking for a polished green finish.
  • Moderate-Traffic Areas: The 20mm pile holds its shape well under regular foot traffic, making it far more versatile than shorter pile options.

Key Features of 20mm Artificial Grass

  • Natural Appearance: The mid-length pile closely mimics the look of a well-kept real lawn, with rich green tones and a realistic texture.
  • Comfortable Underfoot: Noticeably softer than shorter pile grass, making it pleasant to walk and sit on barefoot.
  • Low Maintenance: No mowing, watering, or fertilising — just an occasional brush to keep it looking its best.
  • Easy Installation: Suitable for laying over concrete, decking, compacted soil, and more, with straightforward DIY fitting.
  • Built to Last: Crafted from high-quality synthetic fibres that resist UV fading, wear, and weathering throughout the seasons.

Perfect for a Wide Range of Applications

The versatility of 20mm artificial grass makes it one of our most in-demand pile heights. Whether you're refreshing a tired garden or fitting out a commercial space, it delivers a premium finish at a competitive price.

  • Gardens & Lawns: Replace patchy or high-maintenance real grass with a consistently green, attractive alternative.
  • Patios & Balconies: Transform hard surfaces into inviting outdoor living areas.
  • Play Areas: A safe, cushioned surface for children's outdoor play.
  • Exhibition & Event Spaces: Create a professional, eye-catching display with minimal effort.

What Makes Our 20mm Artificial Grass Durable and Reliable?

Quality is built into every roll. Here's what you can count on from our 20mm artificial grass range:

  • Material Quality: Made from premium polyethylene or polypropylene fibres for a soft feel and long-term resilience.
  • UV Resistance: Colour-stable fibres retain their vibrancy even after prolonged exposure to sunlight.
  • Drainage: Perforated backing allows rainwater to drain freely, preventing waterlogging and keeping the surface clean.

How to Choose the Right 20mm Artificial Grass

With several options in our 20mm range, here's what to keep in mind when selecting the right product:

  • Pile Density: A denser pile gives a lusher, more premium look and tends to be more hardwearing.
  • Colour Variation: Look for multi-tone blends with natural brown thatch for the most realistic finish.
  • Foot Traffic: 20mm grass handles moderate use well — for heavy-traffic areas, consider stepping up to a thicker pile.
  • Roll Width: Choose from our available widths to minimise joins and waste for your specific space.

Why 20mm Is the UK's Most Popular Artificial Grass Pile Height

There's a reason 20mm artificial grass consistently outsells every other pile height — it sits in the ideal middle ground between appearance, comfort, and cost. It's long enough to look genuinely lush and natural, but short enough to stay upright under regular foot traffic without matting or flattening over time.

Compared to 10mm grass, the extra pile height adds noticeable softness underfoot and a more realistic depth of colour — particularly important if the lawn is visible from inside the house or from the street. Compared to 30mm or 40mm options, 20mm is easier to keep tidy, less prone to collecting debris between the fibres, and typically more affordable per square metre without any visible compromise in quality.

For most standard UK gardens — particularly those used for everyday family life rather than heavy sports or pet use — 20mm strikes the right balance. It's the pile height we most commonly recommend to customers visiting our Manchester showroom who want a lawn that looks great in photos, feels comfortable barefoot, and holds up through the seasons without needing constant attention.

20mm Artificial Grass Installation: What You Need to Know Before You Buy

Getting the best result from your 20mm artificial grass starts before the roll is even laid. Here are the key things to consider at the planning stage:

  • Sub-base preparation — 20mm grass performs best over a compacted MOT Type 1 sub-base or a firm, level surface. On concrete or decking, ensure drainage isn't blocked before fixing the grass down.
  • Weed membrane — always lay a quality weed membrane beneath the grass on soil-based installations to prevent growth pushing through the backing over time.
  • Pile direction — all artificial grass has a grain. For the most natural look, lay the pile facing towards your main viewing point (usually the house or seating area) so the light catches it correctly.
  • Joining — if your space requires more than one roll width, use proper jointing tape and adhesive rather than staples alone. With 20mm grass, joins are less visible than with shorter piles when done correctly.
  • Underlay — for added comfort and drainage performance, pair your 20mm grass with a shock pad underlay. Particularly recommended for play areas or spaces where children and pets will spend time.
  • Edging and fixing — secure the perimeter with galvanised nails or fixing pegs every 150–200mm to prevent lifting at the edges, especially in exposed or high-wind locations.
