What to Avoid During Gravel Driveway Installation

1. Lack of Site Preparation

Building a gravel driveway is like most construction projects—it requires adequate site preparation. It isn’t merely spreading gravel on the ground, which would cause the driveway to fail after a few days of use. The surface becomes soft and spongy, burying the gravel and making it difficult to drive over.

Proper preparation includes stripping off the topsoil, including vegetation and loose rocks, until a hard rock bed is reached. A mechanical tamper or roller is needed to compact the soil to make it more solid. This will be the subgrade or bottom layer. However, a sturdy gravel driveway should have sub-base and base layers before the final overlay. Each layer should be compacted to at least four inches thick.

2. Insufficient Drainage

Even if rainwater can drain and seep through the ground, a gravel driveway still needs proper drainage by keeping the surface leveled; otherwise, water run-off can create mud holes through erosion. Moreover, you may need to add another layer of gravel to cover up potholes. The gravel pieces eventually lose their friction because of silt coming up, causing the driveway to collapse.

Apart from adequate drainage, add a landscape or geotextile fabric between the subsoil and bottom gravel layer.

3. No Edging

A solid edging or side form keeps loose gravel stones from scattering to adjacent areas like pathways, lawns, or streets. Moreover, pedestrians can lose their footing and injure themselves on loose gravel. Keep the gravel pieces in their place with a retaining edge made of brick, concrete block, or wood.
