What is chip seal?
Chip seal (sometimes called tar and chip or oil and chip) is built by spraying a layer of hot liquid asphalt emulsion over a prepared, compacted base, then immediately spreading crushed stone chips and rolling them in. The asphalt binds the chips and seals the surface. The result is a textured, natural-stone finish that's firm, sheds water and stops dust and mud.
Why it fits East Mountain properties
- Cost. Much less per square foot than hot-mix asphalt — a big deal on a long driveway.
- Traction. The stone texture gives good grip in snow and on grades.
- Looks. A rustic stone appearance that suits ranch homes and the high-desert landscape.
- No more dust or ruts. A sealed surface instead of loose gravel.
Single vs. double chip seal
A single chip seal is one layer of binder and stone — often used to renew an existing paved or chip-sealed surface. A double chip seal adds a second layer, creating a thicker, more durable surface that's the usual choice when converting a gravel or dirt road. We'll recommend the right build for your traffic.
How we install it
- Grade, shape and compact the base, with a crown and drainage
- Spray hot asphalt emulsion at the right rate for the stone size
- Spread clean crushed chips immediately
- Roll to embed the stone
- Sweep loose stone after curing
Is chip seal right for you?
Chip seal is ideal for long drives, private roads, ranch entrances and low-traffic lots. It's less ideal for areas with lots of tight turning (which can scuff stone loose), for kids on bikes and skates, or where you want a smooth, black finish near the house. Many owners combine both: asphalt at the house, chip seal for the long run out to the road.
Frequently asked questions
How long does chip seal last?
A properly built double chip seal commonly lasts several years before needing a renewal coat, depending on traffic and maintenance.
Will there be loose gravel?
Some loose stone is normal for the first few weeks. We sweep excess chips after the surface cures.
Can chip seal be plowed?
Yes, with care. A plow with the blade set slightly high or with shoes avoids scraping off the stone.
