After over a decade of rain water running down from the roof, I have a small 'moat' around the house, where the water has eroded away the grass and sand (this is Florida, soil is sandy) – see Picture 1. Also, water gets splattered against the house wall, keeping it wet throughout rainy season, which is not a good thing long-term – this is the main concern now.
Adding gutters would cost significantly, so I came up with a cheaper solution:
Simply place a row of pavers with a slight outward tilt along the house, which will catch the falling water's impact, and run it off in the grass or splatter it outwards (hence the slight tilt) – see picture 2.
The question is – will that work as expected?
- it took the water over a decade to erode through the grass and about two inches deep, so it's not that bad
- nobody will ever walk on them, so the pavers do not need to support that. Therefore, I plan to simple place them in the sandy dirt, next to each other.

I did this years ago along one side of my home and it's worked well. The area between the pavers and the house you'll want to turn into a little flower bed or mulch it over as trying to mow it can be a pain (was for me anyway).
I also put some pavers at the end of my downspouts to prevent erosion there. A few on the ground then one on top so the water coming out of the spout will hit the top one to slow it down then run off the bottom ones into the ground.
