Chip Seal Contractor in Spokane, WA

Long Driveways and Private Roads.

Chip seal is one of the most practical and cost-effective surface options for long driveways, acreage properties, and private roads throughout Eastern Washington. It combines asphalt binder and aggregate stone to create a durable, textured driving surface with strong traction and long-term performance.

For homeowners with long driveways or large rural properties, chip seal provides a significantly lower-cost alternative to full asphalt paving while still delivering a clean, durable finished surface.

Why Our Double Chip Seal System Stands Out

Most residential chip seal contractors install only a single chip application. At Cornerstone Paving WA, we install a full double chip seal system on residential driveways because we believe it creates a tighter, stronger, and longer-lasting finished surface.

A second application helps improve stone retention, strengthen the surface mat, reduce loose rock over time, and create a more durable driving surface for Spokane-area conditions.

Many homeowners are surprised to learn our double chip seal pricing is often competitive with — and sometimes even lower than — other contractors’ single chip seal installations.

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.

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.

What is chip seal and how does it work?
Chip seal is a pavement surface treatment that applies a hot liquid asphalt binder to an existing or prepared surface and immediately embeds crushed stone aggregate into it. The stones are compacted into the binder to create a textured, weather-resistant surface.
A double chip seal system applies two full layers of asphalt binder and aggregate rather than one. This creates a tighter, stronger surface with better stone retention, reduced loose rock, and longer-lasting performance. Cornerstone Paving WA installs double chip seal as standard on residential driveways.
A professionally installed double chip seal surface lasts longer than a standard single application. With proper maintenance it can be reapplied at the end of its service life to extend pavement durability without full replacement.
Yes. Chip seal typically costs 30 to 50 percent less per square foot than traditional asphalt paving. It is the most cost-effective option for homeowners with long driveways or large surface areas.
Yes. Chip seal performs reliably through Eastern Washington’s freeze-thaw cycles because the aggregate surface allows for minor movement without cracking. It has been used on rural roads and driveways across the Pacific Northwest for decades.
How long after chip seal installation can I use my driveway? Most chip seal driveways are ready for light use within 24 to 48 hours of installation. We give you a specific timeframe based on weather conditions before we leave the property.
Yes. Chip seal can be applied over an existing surface that is structurally sound. If the base has significant damage or failure, preparation work will be needed before application.
Yes. We visit your property, assess the surface, and provide a written estimate at no charge and with no obligation to proceed.
