Seeding pebbles over the surface of wet concrete adds visual interest to pavement. Creating an exposed pebble finish on pavement is a do-it-yourself task that only slightly increases the total cost of the project. Pebbled concrete forms a level, slip-resistant surface that suits driveways, walkways or patios. Choose smooth, colorful pebbles that complement existing colors in your yard.

How to Create a Pebbled Concrete Surface

Step 1: Measure and Outline the Site

Measure the area and add 3 inches to the sides for the form boards. Outline the site with landscaping paint, tracing the side of a board so the lines are straight.

Step 2: Dig and Compact the Surface

Unearth the area with a shovel until there's an 8-inch-deep expanse with vertical walls. Press the bottom of a hand tamper over the surface so the loose dirt feels compact.


Step 3: Tamp the Aggregate

Add 3/4-inch aggregate into the expanse and spread it with a shovel. Insert a measuring stick through the aggregate to the compacted subsoil. Tamp the aggregate and add more to create a 5-inch-thick base. The tamped base is flexible enough to buffer the concrete from ground tension and enable water to drain away.

Step 4: Fit Boards

Fit 2-by-4 inch form boards against the inner walls and screw them together with a drill. Brace the boards with wooden posts around the outer perimeter.


Step 5: Mix Concrete

Mix the concrete mix in a large wheelbarrow with water using a paddle and drill. The composition should be thick but spreadable.

Step 6: Pour the Concrete Mix

Pour the mixture over the base using a gauge rake to fill the corners and sides. Place a wood board on the wet surface and pull it back and forth to make it level.


Step 7: Lay the Pebbles

Lay decorative pebbles over the concrete with a shovel. Spread any small piles with a broom for even coverage. Lay a board over top and press the pebbles into the concrete. Wait about two hours so the surface can start to set.

Step 8: Expose the Pebbles

Push off the thin coating of cement paste around the sides of the stones with a soft broom. Expose only the top of the pebbles so they remain firmly embedded in the concrete. Hose off the cement you removed.


Step 9: Cover the Pavement for One Week

Cover the pavement with moist, breathable fabric and keep it moist for a week.

Step 10: Apply Sealant to Finish

Seal the pavement with clear, penetrating sealant using a roller brush to guard against water damage and wear and tear.
