How to install Riprap Med
-
1
Slope the trench
Minimum 1% slope (1" per 8 ft) so water actually flows.
-
2
Wrap with fabric
A nonwoven filter fabric keeps fines out of the void space.
-
3
Surround the pipe
4" of stone below, 4-6" above the perforated pipe.
-
4
Backfill carefully
Top with native soil or sod; do not leave the stone exposed long-term unless intended.

Riprap for a downspout swale
Small job, just 3 tons of riprap to line a swale where the downspouts dump out and to hold a little slope by the walkout basement. Rock was clean and sized right, no oversized boulders I couldn't lift. The driver dropped it uphill of the swale like I asked so I could work downhill. Will order again.

Stopped the ditch washing out
Lined a drainage ditch along the side of my property with 8 tons of riprap after two springs of watching it wash out. The rock came in the 4 to 9 inch range as listed, nice gray color, chunky and angular so it locks together on the slope. Driver called ahead and tailgated it in a line along the ditch, which saved me hours with the tractor.
