This artificial grass has been installed in April 2010. It was time to do some maintenance work to get it looking like new. We had to take away all grass in order to level and compact the sand under the grass. We changed some broken antiroots materials and we had to take away some roots from a tree next to the grass area. After reinstalling the clean grass, we added silicea sand and brushed all grass area well. The result is incredible. It looks like the first days in April 2010.
