Question 1

How much artificial grass do I need?

Accepted Answer

Measure your lawn's maximum length and width, then plan rolls so the pile direction runs the same way across the whole area. Artificial grass comes in fixed roll widths (commonly 2 m and 4 m), so the calculator above works out rolls to fit your shape with the fewest joins and least waste.

Question 2

What base do I need under artificial grass?

Accepted Answer

Lay artificial grass over a compacted sub-base of MOT Type 1 topped with a granite or grano dust laying course, blinded smooth. The calculator estimates base aggregates from your area and depth so you can order sub-base and laying course together.

Question 3

Which way should the pile face?

Accepted Answer

Lay all rolls with the pile leaning the same direction, ideally facing towards the main viewpoint (the house or patio). Mismatched pile direction across a join shows up as an obvious colour change.

Question 4

How do I join artificial grass?

Accepted Answer

Butt the roll edges tightly together over joining tape and bond them with outdoor adhesive, keeping the pile out of the glue. The calculator includes tape and adhesive based on your total join length.

Question 5

How many pins or staples do I need?

Accepted Answer

Fix the perimeter and any joins with galvanised U-pins or ground staples roughly every 150–200 mm around edges. The calculator estimates pins from your perimeter and join lengths.
