We have a problem with our backyard which is very muddy when raining. We live in Louisiana where rain is frequent so my wife and I decided to install artificial grass to try if it will do the magic. The installers excavate soil before putting in the base and laying the artificial grass and voila! Not only our muddy problem has been solved but we also have a place for the kids to play. The 4 days wait for them to install it is definitely worth the wait. Will recommend this to our friends and families.
