Artificial Grass: What It Is, How It Works, and What You Need to Know

When you think of artificial grass, a synthetic alternative to natural lawn that mimics the look and feel of real grass without the need for watering, mowing, or fertilizing. Also known as synthetic turf, it’s become the go-to solution for UK homeowners who want a green lawn without the hassle. It’s not just plastic blades glued to a backing — it’s a system. The grass itself is only one part. What’s underneath, how water moves through it, and whether you need sand all matter just as much.

That’s why drainage, the ability of artificial grass to let water pass through quickly and prevent pooling is non-negotiable. If your lawn turns into a swamp after rain, it’s not the grass’s fault — it’s the install. A proper base with crushed stone and a permeable underlay lets water flow away, not sit. Then there’s sand infill, a layer of fine, rounded sand spread over the grass blades to help them stand up, add weight, and protect the backing. Too little, and the grass flattens. Too much, and you risk compacting the base or washing it away. And don’t forget the grass underlayment, the hidden layer between the soil and the turf that blocks weeds, supports drainage, and stabilizes the surface. Skip it, and you’ll be fixing problems in a year.

People often assume artificial grass is a set-it-and-forget-it solution. But it’s more like a car — you need the right parts, installed right, to keep running smoothly. The best lawns aren’t the ones with the shiniest blades. They’re the ones built on solid foundations, with drainage that works, and sand applied at the right time and amount. This collection of posts breaks down exactly what works, what doesn’t, and why. You’ll find real fixes for soggy spots, clear answers on how often to add sand, and the exact layers you need under your turf. No theory. No guesswork. Just what you need to get it right the first time.
