Yes and yes.
A definite best buy in our household. Has transformed muddy, mossy lawn to all year round, free draining, useable playing and sitting area. After a downpoor, it takes about 30 mins to be completely dry if the sun is out.
It cost about £500 for a 4m x 8m piece and we laid it ourselves. Easy enough once you take the time to level the ground, wead it and get some sand and permeable membrane down to inhibit weeds.
My tip would be to spend as much as you are comfortable with and get a good blended mix of grass blades – not the uniform green stuff which is cheaper and looks it.
We are a lawnmower free family. 😀
