At an installed cost of about $7,000, itâs an appliance that makes very little financial sense for most people. Tesla lists the price of the battery at $3,500, but that does not include installation, or an additional piece of equipment called an inverter that is needed to connect the battery to the home.
Strong blacktop driveways are typically built using crushed angular gravel as a base. This gravel needs to be a minimum of 6 inches thick for light vehicle traffic such as cars. If you expect larger commercial trucks on your driveway, I would install a gravel base that is a minimum of 8 inches thick. The soil beneath the gravel must also be of good quality.
1. Calculate your need for gravel and crushed stone. The first step to installing your new gravel driveway is to determine how much stone material youâll actually require. In addition to the gravel, youâll need a base layer of crushed stone in order to add support and promote healthy drainage. For a rectangular driveway, youâll need to multiply the length x the width x the depth of the project area to learn how many cubic yards of crushed stone and gravel youâll require.
