Version 04/20 updates:
The amount of stone above, below and between the chambers now sets to the selected models default each time a new model is selected. The user can override these values, if they want extra stone, but as soon as a new model is selected from the drop-down everything goes back to the default values.
Watch the How To Instructional Video to find out how our Stormwater Design Calculator can help you design your next CULTEC stormwater management system.
