Sportworks Design turf experts performed a series of drainage tests on the fields. First, they calculated the speed at which a controlled amount of water drained through the turf carpet and drainage system in various areas of the field. They compared their findings to the industry standard performance rates and the manufacturers specifications at the installation of the turf system. Next, they rolled back a portion of the turf carpet and performed the same series of tests on the rock below. Finally, they dug into the subgrade to look for signs of damage or contamination. They found that the area of the field that was not draining properly had minor contamination. The perforations in the synthetic turf back were partially blocked by a foreign substance. The foreign particle dropped vertically down into the stone base, but did not appear to spread laterally.
The drainage tests provided a documented record of the current performance status of the turf and drainage systems. Armed with this vital information, the school district is able to make informed decisions when planning the repair of their synthetic turf field. Instead of the cost and schedule increases that typically come with change orders due to troubleshooting during construction, this work will likely be completed on a quicker schedule and within a manageable budget.
