Artificial Grass Installation in Hertfordshire

The Sub-Base Engineering Process

An artificial lawn is only as durable as the ground beneath it. Many failed installations suffer from sinking, pooling water, or weed breakthrough because shortcuts are taken during excavation. At Dominion Landscapes, we adhere to strict structural groundwork standards:

• Excavation: Stripping organic topsoil down to a consistent depth of 75mm to 100mm to eliminate root systems and organic matter.
• Sub-Base Compaction: Installing a heavy-duty layer of MOT Type 1 aggregate, compacted thoroughly using mechanical plate compactors to create a load-bearing, frost-resistant foundation.
• Geotextile Membrane: Laying industrial-grade weed suppression membranes that prevent unwanted growth while allowing rapid vertical water drainage.
• Screeding Layer: Finishing with a fine granite dust or sharp sand screed, laser-leveled to achieve a perfectly smooth, stable contour.

Turf Specifications & Yarn Technology

We source commercial-grade synthetic turf engineered specifically for the British climate. Key technical characteristics include:

• Pile Height & Density: Ranging from 30mm to 40mm with high stitch rates, ensuring a lush, natural vertical recovery after foot traffic.
• Monofilament C-Shape or Diamond Yarns: Designed to bounce back instantly under pressure, eliminating the matted look common in cheap alternatives.
• Porous Polyurethane Backings: Fully perforated backing systems that drain water at rates exceeding 60 litres per minute per square metre, preventing puddles during heavy Hertfordshire downpours.
• Pet-Friendly Integration: Non-toxic, antimicrobial sand infill options that neutralize odors and provide safe, mud-free play areas for dogs and children.

Longevity and Upkeep

With professional installation and minimal routine maintenance—such as occasional brushing and leaf clearing—a Dominion Landscapes artificial lawn maintains its pristine aesthetic for 15 to 20 years, completely eliminating mowing, weeding, and watering.
