Marble chips lend a crisp, refined look to landscape pathways, borders and patios. Most landscape marble is bright white with a glittery, reflective appearance, although gray chips are occasionally available. Long-lasting, marble chip landscape features depend on proper preparation of the base and barriers that keep marble chips in place.
Outline the area where you would like to install the marble chips by spraying with landscaping spray paint to create the borders.
Dig out the soil inside the outline to a depth of 6 inches using a shovel. Keep the sides firm and straight up and down. Fill in the area with a 2 1/2-inch layer of crushed stone for the base. Dampen the crushed stone with water by spraying the area lightly with a hose. This helps in keeping the dust settled and compaction of the stones.
Pack down the crushed stone with a hand tamper until it compresses into a 2-inch layer. Strike the surface of the stone pack evenly with the tamper to compact it.
Roll landscaping fabric over the crushed stone pack. Trim the fabric to fit inside the space, using a utility knife. The fabric helps block weeds from growing up into the marble and keeps the stone pack in place.
Insert your chosen edging around the edges of the area. Hammer the edging into the ground with a mallet until the top edge is flush with ground level. If using plastic edging, drive stakes at a slight downward angle through the edging near the bottom every 24 to 48 inches using a mallet.
Fill in the remaining depth of the area with marble chips. Leave approximately 1/2 inch between the top of your edging and the marble chips. Rake and even out the marble chip surface using a bow rake.
