Pea gravel escapes the confines of its path or drive over time. Gravel works its way into the ground beneath the drive if the excavated area is not properly lined. Edging the path or drive keeps the gravel from escaping its borders. Lining and edging are two essential tools needed to keep pea gravel in place and prevent the trouble and expense of replacing it every few years.
Cut trenches along the edges of the drive with the blade of a shovel.
Measure the appropriate amount of garden fabric to cover the drive area, extending the entire width of the area and past the edges so that the edging trenches are lined also. Lay the landscaping fabric.
Install the plastic landscape or stone edging into the trenches on either side of the drive area. Roger Cook, landscape contractor for "This Old House," suggests the alternative of setting metal edging down into the trenches and driving metal spikes into the ground every few feet up against the edging to keep it in place. Measuring, cutting and laying treated wood planks the width of the drive so that the ends of the planks brace the metal holding spikes adds a measure of security.
Pour the pea gravel into the lined, edged area and spread it to the desired thickness with a rake, making sure that the layer of gravel is thick enough to provide adequate coverage but not so thick as to breach the landscape edging on either side.
Set pea gravel in concrete for a permanent solution to gravel movement. However, this treatment eliminates many of the benefits of a pea gravel treatment. It is harder to lay, requires professional installation if the drive covers a substantial area and requires the same maintenance and repair as a standard concrete drive.
