How to Embed Glass in an Aggregate Landscape

Clean the existing aggregate surface with a hose and scrub brush. Use stain remover if it has oil or grease stains, as debris and stains will weaken the bond between the old aggregate and new aggregate used to adhere the glass.

Roll bonding adhesive over the surface with a paintbrush.

Fit wooden form boards around the perimeter and screw them together with a drill. Hammer stakes into the ground directly behind the forms to brace them.

Mix enough aggregate to pour a 1-inch layer over the surface. Open the aggregate mix in a wheelbarrow and slowly add water. Stir with a paddle bit and drill until it has a thick, but pourable consistency.

Pour or shovel the aggregate onto the surface, and spread it with a gauge rake. Drag a long straight edge back and forth over the top to make it level. Make it as smooth as possible using a squeegee.

Shake glass chips onto the surface with a shovel. Use a gloved hand to spread the chips so they are flat. Scatter them evenly over the surface.

Lay a wood board over the top and apply even pressure over the whole board to embed the chips into the wet aggregate. Press on the glass chips gently until they are more than halfway, but not completely buried. Repeat this step for the whole surface.

Cover the wet surface with a breathable fabric like burlap. Spray the fabric with water continually over four days to dry the aggregate slowly. The extra moisture is not enough to prevent the aggregate from drying. Aggregate will continue to absorb moisture as it cures, preventing the material from drying out too fast and becoming brittle.
