What is 3/4"–1-1/2" round rock?
This is natural river rock screened to between 3/4" and 1-1/2". The smooth, rounded stones leave large open gaps with no fines, so water moves through quickly and the rock doesn't clog.
It's our most popular rock for French drains, and it works great around drain pipe, behind retaining walls, in dry wells and in larger landscape areas where you want a natural look.

Round drain rock questions
The smooth, round stones don't pack together, so they leave open gaps for water to flow through. With no fines in the mix, the rock stays clean and the drain keeps moving water.
Both drain well. Round drain rock is smooth river rock that's easy to rake and has a more natural look. Crushed drain rock has angular edges that lock together a bit more, so it stays put better under foot traffic.
In most drains it's a good idea. Drain fabric keeps the surrounding soil from washing into the rock, which helps the drain keep working longer.
The 3/4"–1-1/2" size has bigger gaps between the stones and moves more water, which makes it the go-to for French drains. The 1/4"–3/4" size is smaller and more decorative, so it's popular for beds and paths.
