What Is Chip Seal, and Is It Right for Your Property?

How Does Cornerstone Paving WA Install a Double Chip Seal System?

Every chip seal installation at Cornerstone Paving WA follows a proven process designed to produce a surface that bonds correctly, drains properly, and holds up through Washington’s demanding seasons. Because we install a double chip seal system, our process includes two full applications of binder and aggregate.

1. Surface Preparation

What preparation is done before chip seal is applied?
We inspect the surface, fill any holes or damaged areas, treat problem weed areas, define the driveway edges, and complete any grading needed to ensure proper drainage before any material is applied.

2. First Emulsion Application

How is the liquid asphalt applied in chip seal?
Premium polymer-modified emulsion is sprayed evenly across the prepared surface at the correct temperature to ensure proper adhesion when the aggregate is applied immediately after.

3. First Aggregate Layer

How are the stone chips applied in chip seal?
Crushed stone chips are spread immediately over the hot asphalt binder, creating an even, continuous layer across the full surface area before the binder cools.

4. Compaction

Why is compaction important in chip seal installation?
Pneumatic tire rollers press the stone chips firmly into the asphalt binder, locking them into a tight, bonded surface that resists loosening under traffic and weather.

5. Second Emulsion Application

Why is a second emulsion application applied?
A second layer of polymer-modified emulsion is applied over the compacted first layer, creating the foundation for the second aggregate application that defines our double chip seal system.

6. Second Aggregate Layer and Final Rolling

What does the second aggregate layer accomplish?
The second aggregate layer is installed and compacted with final rolling for proper embedment. This second application improves stone retention, strengthens the surface mat, and reduces loose rock over time.

7. Fog Seal Finish and Sweeping

What is the final step in a double chip seal installation?
A protective fog seal finish is applied for improved durability and appearance. Loose chips are then swept from the surface, leaving a clean, finished driveway ready for regular use.

Who Gets the Most Value from Chip Seal in Eastern Washington?

Chip seal isn’t the right choice for every property but for the right property, it’s one of the best surface investments available. Here’s who benefits most from chip seals in the Spokane region.

Homeowners with Long Driveways

If your driveway runs 200 feet or more, the cost difference between chip seal and full asphalt paving becomes very significant. Trusted chip seal driveway contractors know that chip seal delivers comparable durability and all-weather performance at a fraction of the asphalt cost, making it the practical choice for long residential driveways throughout Eastern Washington.

Rural and Acreage Property Owners

Farms, ranches, and acreage properties often have multiple access roads, outbuilding approaches, and large surface areas that need reliable surfacing. Chip seal handles these large-scale applications efficiently and affordably something full asphalt paving rarely makes financial sense for.

Owners of Private Roads

Private road maintenance is a real cost for many Eastern Washington property owners. Chip seal provides a durable, low-maintenance surface that handles regular vehicle traffic without the capital expense of asphalt.

Homeowners Replacing Gravel Driveways

If you’re ready to move beyond a gravel driveway but aren’t ready to invest in full asphalt, chip seal is the logical middle step cleaner, more durable, and significantly lower maintenance than gravel, at a realistic price point.

Property Owners Prioritizing Traction

The textured aggregate surface of chip seal provides superior grip in rain, snow, and ice compared to smooth asphalt, a meaningful advantage for steep driveways or properties that see heavy winter conditions.

None of these problems fix themselves, and most get significantly more expensive the longer they sit. The good news: caught early, almost all of them are solved with routine maintenance instead of a full replacement.

BENEFITS

What Are the Benefits of Chip Seal for Spokane Homeowners?

Chip seal delivers reliable surface protection at a significantly lower cost than traditional asphalt. Here is why it is a smart choice for homeowners across Eastern Washington.

Cost-Effective

Chip seal typically costs 30 to 50 percent less per square foot than traditional asphalt paving, making it the practical choice for large surface areas and rural properties.

Natural Appearance

The stone aggregate gives chip seal a natural, organic look that complements rural properties and blends well with gravel and landscaping surroundings.

Excellent Traction

The textured aggregate surface provides superior grip in rain, snow, and icy conditions, making it a safer choice for Washington’s wet and cold winters.

Long-Lasting

A professionally installed double chip seal surface lasts longer than a single application and can be reapplied to extend pavement life without the cost of full replacement.

Weather Resistant

Chip seal handles Eastern Washington’s freeze-thaw cycles well because the aggregate surface allows for slight movement without the rigid cracking that affects solid surfaces.

Low Maintenance

Chip seal requires minimal upkeep between applications. Periodic resealing is typically all that is needed to keep the surface performing well.

Quick Installation

Most residential chip seal jobs are completed in a single day, with the surface ready for use within 24 to 48 hours of application.

Customizable Finish

Chip size and aggregate color options allow chip seal to be tailored to the aesthetic and functional requirements of any property.

How to Maintain a Chip Seal Driveway

A properly installed chip seal surface is low-maintenance by nature but a few simple practices will keep it performing well for years and extend the time between reapplications.

In the First 2–3 Days After Installation

Keep vehicle speeds low on the new surface. Avoid sharp turning movements and heavy vehicle loads. Some loose aggregate is normal in the first few days as the binder fully cures this will decrease quickly with normal traffic.

Ongoing — Address Edges

Chip seal edges can be vulnerable to cracking or lifting over time, especially where the surface meets grass or unprepared ground. Keep edges clear of vegetation and address any lifting early to prevent water from getting underneath.

Every Few Years — Fog Seal or Reapplication

Chip seal can be refreshed with a fog seal application to restore the binder and lock down any loosening aggregate. When the surface reaches the end of its service life, a new chip seal application can be installed over the existing surface extending pavement life without the cost of demolition or full replacement.

Year-Round — Drainage

Good drainage is the key to chip seal longevity in Spokane’s climate. Keep drainage channels and ditch lines clear so water moves away from the surface rather than pooling at the edges or running under the chip seal mat.

What is a double chip seal system?
