Heavy clay soil, constant rain, and poor drainage – it’s a familiar story across the North West. Many gardens in Lancashire, Greater Manchester, and Cheshire spend half the year waterlogged, turning from lawn to swamp after just one wet weekend. Artificial grass offers a way out – but only if it’s fitted with proper drainage, solid groundwork, and the right materials underneath.
🔑 Key Takeaways
- Waterlogged gardens are common across the North West – but fixable with proper excavation and drainage.
- Artificial grass needs a free-draining base, not sand alone, to stay firm and dry year-round.
- As Good As Grass installations replace boggy soil with structured layers that let rain flow straight through.

Why Lawns Get Waterlogged in the North West
Most North West gardens are built on clay-heavy ground that holds onto moisture like a sponge. Add frequent rainfall, compacted soil, and old turf roots – and you’ve got a recipe for standing water. We see it constantly in Burnley, Bury, and Rossendale – homeowners tired of mud, puddles, and grass that never fully dries.
Artificial grass can’t just be rolled on top. Without proper excavation and drainage layers, it’ll trap water the same way. That’s why we strip everything back and rebuild the base from the ground up.
The Right Groundwork Makes All the Difference
Every successful installation starts below the surface. Here’s how we rebuild boggy gardens into solid, free-draining spaces:
- Excavation: We remove around 75–100mm of saturated soil and roots to expose a firm, stable base.
- Membrane: A geotextile layer stops weeds and separates the ground from the aggregate.
- Sub-base: We compact layers of MOT Type 1 aggregate – the same stone used under driveways – to create structure and drainage.
- Fines layer: A top layer of sharp sand or limestone dust smooths the surface and locks everything tight.
- Turf install: Finally, we fit the artificial grass with secure edging to stop any water creeping back in from the sides.
It’s physical work, but this is where the real transformation happens. Once the base drains freely, the surface stays clean and dry – even after a storm.
Extra Drainage Options for Wet Gardens
In especially boggy gardens – often found in Wigan, Chorley, and Preston – we add additional systems below the surface. These can include:
- Perforated drain channels beneath the base to redirect groundwater.
- Gravel soakaways in problem corners or low points.
- Shock pad layers (like our Safety Flooring & Shock Pads) to improve drainage and comfort underfoot.
Combined with non-infill turf and UV-stable fibres, this setup handles rain year-round – perfect for shaded gardens or those backing onto fields.
Real Results: From Mud to Multi-Use Garden
We’ve replaced countless “bog gardens” across the North West with practical, beautiful lawns. One recent job in Bolton started as a clay pit that stayed wet for days after rain. After full excavation, sub-base rebuild, and a non-infill turf install, the family finally had a dry, usable garden for the first time in years – even after heavy storms.
Another install in Rawtenstall transformed a shaded slope that never drained properly. With a custom base, lateral drains, and the right gradient, the garden now stays firm underfoot all year long.
Maintaining Your Artificial Lawn After Installation
Once the groundwork is done right, maintenance is simple. A quick brush every month keeps the pile upright and clears away debris. For long-term care, our maintenance and repair service offers deep-cleaning and surface restoration to keep your lawn draining freely.
Because artificial grass drains from top to bottom, it’s also ideal for pet owners. Our pet-friendly grass includes non-absorbent backing, so rain helps wash away any residues — leaving it clean, dry and fresh, no matter the weather.
FAQs – Artificial Grass for Wet Gardens
Can artificial grass really fix a boggy garden?
Yes – if installed with proper excavation and drainage layers. Our installations rebuild the ground to let water flow through freely.
Will water pool on artificial grass?
No. Quality turf and the right sub-base allow rain to drain straight through, preventing puddles and soggy patches.
How deep should the base be for a wet garden?
Usually 75–100mm, depending on soil type. Deeper excavation may be needed for heavy clay or poor gradients.
Does artificial grass need extra drainage pipes?
In severe cases, yes. We can install perforated pipes or gravel soakaways under the lawn to redirect water.
How much does it cost to fix a waterlogged garden?
Costs depend on the extent of excavation and drainage work. Most full installations start from £45–£85 per m² – see our Artificial Grass Cost Guide for more detail.
