This section of Thundaflo was installed in 2013 before ductile iron grates were available, the photo was taken in November 2019. It's still rock solid.

Mobil Energy - Washdyke. This section of Thundaflo was a real challenge in terms of channel design. Half the section we literally had to drain uphill; this was achieved by using Thunda-Torrent which has a supper steep 1.8% gradient. If you look closely you can see upward slope at the far end of the forecourt. On the near section we had to keep the depth of the channel very shallow to stay above existing fuel lines... in this section we used Thunda Zero gradient.
