I am installing artificial turf in my backyard. I would like to divide it with a path filled with decorative rocks.

The whole area was excavated 4" deep and I covered it with geotextile fabric liner to keep weeds from growing. The area with grass is filled with base rocks and topped with a bit of sand. The path is completely filled with white rocks. I need an edge to divide the base rocks from the decorative rocks.

I was thinking of using 2" thick patio paver and pour cement under it. Is it okay to just pour it over the geotextile fabric?

I saw on YouTube people pouring dry sand cement and just resting the pavers on top. When everything is leveled and aligned, they just spray mist. Seem easy. No digging. This is not structural. Just for decorative purposes and to keep the 2 types of rocks from mixing up.

This is how I would build up my edge/border How I would install my edge

  • Is the brick part of the design you want? If not why not use actual edging? Steel, Vinyl, wood, right down to the fabric. Like in the photo, I think that's wood.

  • @jay613 i ruled out wood because my border is curved and it will rot over time. I also rule out steel because of rusting. I guess I could go with Vinyl but having a larger border makes it look more attractive.

If the dirt under the fabric was not disturbed it should be compacted enough for you to place concrete on it and support your bricks. However, it would be less labor intensive to just use two layers of pavers though. Placing concrete is a lot of work. The box stores sell standard concrete bricks that are pretty cheap.

If you want a curved border, Menards (and probably other box stores) sells a "Crescent Edger Block" that is round with a circular piece missing and looks like a crescent moon. When you fit them together they can be laid in any radius larger than their size and can make a sweeping arc easier than rectangular bricks without any gaps.

In certain situations concrete is poured over a plastic barrier by design. If you decide to use a cement/sand dry mix the barrier should stop any unwanted sand migration to your base
