So, you want slope drainage, but you don't want the slope drainage pricing... no problem.
First of all, let me tell you a myth about sloped drainage. This has been a very old marketing technique that other companies have been loving for a long time, because they can charge you a lot, thinking you are getting more, but there are many ways to divert water. Yes, we do sloped drainage in our concrete systems, but its not worth it (in our opinion) for homeowners at all.
Introducing our cascade method of installation. This is our "step down" method, changing heights in the system to allow for more water flow, as much as slope (much more actually in some depths) with 40% less of the price. So installing it is very easy.
First off you can use our cascade method with your 4 and 8 inch channels. You just have to go down the steps. All you have to do, is when the height of the system changes, make sure to put the corresponding Cascade Adapter in the joint. Place the other channel underneath, level with our Installation Brackets... and you are good to go.
There you have it, all the benefits of slope drainage, half the hassle, half the price, and your water issues are over. Water finds a way out, slope or no slope... do it right. Below is a chart on how it all works. If you have any questions, please contact Standartpark, we are always waiting to help you. Thank you
