It looks like you are installing your French drain on the outside of the flower bed and very close to the ground surface. I have flower beds up against my house and I’d like to keep my basement dry(old stone foundation). Should i dig up the flower beds and go right against the foundation, or is it sufficient on the outside of the flower beds?
On your demo, if you had a holes-down pipe I wonder how much more headwater (water height) is needed to match the flow of a fully 360 hole pipe. At 2:30 you can see the headwater is almost 2 inches higher than the tailwater exiting the pipe. If you've ever seen a water-table map for the floodplains then you'd see how I think these pipes should start at the discharge & maintain minimum slope to the problem area so that these FD & other intake devices have the maximum amount of headwater to push the max amount of water into the pipe. I love my 6 inch smooth wall installed at minimum slope, it's almost level. As I ponder the math it's quite interesting though is limited to the max capacity of the discharge size. I have abandoned FDs though b/c my 20ft section has poor intake & my 200ft of 10 inch did not outperform the surface inlets in our flash-floods.
Tampa, Florida, is lucky to have you!
Agreed, watching their videos I've been thinking of hiring them for their consulting at least as I am in Orlando, FL
Great information
Great video. What do you guy think about the premade "French drain" that's sold at home Depot?
Just emailed you.
Fabric then rock then pipe or fabric pipe then rock?
These guys are why tampa bounces back from huricans so fast
Hurican? More like huricant!
