Our Beginner Friendly System is Designed to Make Kits Easily

These blocks were specially designed to make hardscape features. These are not repurposed retaining wall blocks. This produces easy-to-make kits that save time. The wedge shapes help increase the bonding ability for a solid product built to last.

Achieve a Natural Stone Look With Our Random Stone Layout

Our stones are produced with through-body colored concrete. Then they are tumbled to give them a naturally aged look. The three sizes of block can create seven different face sizes creating the randomly laid appearance of natural stones.

Save Time With Our No Mortar Needed Building System

There is no mess and mixing of mortar. Our kits are simply glued together. You squeeze special adhesive from a caulk gun. This makes construction and cleanup a breeze.
