There is no easy retaining wall to build. All retaining walls require some level of labor and skill to construct properly. However, if you are looking for an easier option, a concrete block wall may be a better choice than a traditional stone wall. A concrete block wall is easier to build than a stone wall, but it is not as sturdy or long lasting.

To build a retaining wall that won't crumble or collapse, you need to use something called geotextile fabric. Geotextile fabric is a synthetic woven material that's used to stabilize and reinforce soil. It prevents the soil from eroding and keeps it in place, which is exactly what you want for your retaining wall.The easiest way to install geotextile fabric is by using a trenchless method. This involves digging two small holes at either end of the area you want to cover with the fabric. You then slide metal rods through the holes and into the ground, and use these rods as anchors to hold the fabric in place.
