Ok, so we finally get that much needed rain. However with a heavy downpour, there often arises a common landscape problem: washout. This happens most often at the bottom of downspouts, especially during heavy rains. In this common problem, the gutters collect the roof runoff and channel it down the downspout, the result of which is something like a powerful jet stream of water eroding the ground beneath your downspouts. Soil and mulch don't stand a chance, even stones can get moved around as the high velocity water is jettisoned into your yard or onto the driveway. Buy this downspout splash block and slow that water down.
