If you are a homeowner or a business owner in Seattle, you know things here are a little different. That is true for something as basic as asphalt paving. You cannot just put down some blacktop and expect it to hold up. Our city has its own quirks. If your paving crew does not understand these quirks, you will have problems later on.
Seattle's Weather: More Than Just Rain
Everyone knows it rains a lot here in Seattle. It is not just the constant drizzle that wears down asphalt. The freeze-thaw cycles we get in winter really do a number on asphalt. Water seeps into tiny cracks as well as freezes as well as expands. Then it thaws. This leaves bigger cracks and eventually potholes. We have even seen roads buckle during our increasingly common heatwaves. This happened on 4th Avenue S. in SODO. That kind of temperature swing means your asphalt needs to be tough as well as flexible. It needs to be built to handle both the wet weather and the occasional extreme heat in Seattle.
Our Tricky Seattle Soil
Underneath all that asphalt is the subgrade. In Seattle, that subgrade can be a real mixed bag. We have everything from heavy clay that holds water to sandy or rocky soils that drain too fast. In addition, there is the urban fill you find in older, developed neighborhoods. This fill can be a mix of all sorts of stuff. If your paving contractor does not assess that soil properly and prepare the base right, you are setting yourself up for an uneven surface. You will also have drainage issues as well as premature failure. A stable base is important for the longevity of an asphalt surface. That often means a good layer of crushed stone or gravel. This layer needs to be properly compacted to give your asphalt a solid foundation.
Common Paving Projects Around Here
Oasis Asphalt Paving sees all kinds of projects across Seattle. This includes projects on the steep hills of Queen Anne as well as in the bustling commercial districts downtown. Here are a few types of projects that pop up regularly:
- Residential Driveways: Homeowners want something durable that handles our Seattle weather as well as often sloped lots. This is true whether it is a new build in West Seattle or replacing an old, cracked driveway in Capitol Hill. A smooth, well-drained driveway is a big plus for curb appeal as well as property value.
- Commercial Parking Lots: Businesses all over Seattle, from Ballard to Georgetown, need parking lots that can handle heavy traffic. These parking lots also need to look good for customers as well as drain properly. A well-maintained parking lot is like a welcome mat for your business.
- Access Easements and Private Roads: These need to be built to specific City of Seattle standards. This is especially true in areas with multiple dwelling units. They often need a minimum thickness of asphalt over a crushed rock base. They also need proper drainage to manage stormwater.
- City Street Paving: You will see the City of Seattle Department of Transportation (SDOT) working on arterial streets all the time. They are repaving roads like Denny Way to make them safer as well as smoother. They are always trying to keep our infrastructure in good shape for Seattle.
Why Local Expertise Is Not Just a Buzzword
This is not just about knowing how to lay asphalt. It is about knowing where you are laying it in Seattle. A contractor who has been working in Seattle for years understands the nuances of the area. Oasis Asphalt Paving knows these things well:
- Permitting and Regulations: Some paving projects require permits. This is especially true if you are adding or replacing more than 750 square feet. You need a crew that knows the local codes as well as stormwater requirements. Our team can help you navigate that whole process in Seattle.
- Drainage is Key: With all our rain in Seattle, proper grading and drainage are important. Standing water will wreck your asphalt faster than anything else. We are talking about slopes that direct water away. We also mean clean gutters as well as effective drainage systems.
- Material Selection: The right mix for Seattle's climate is important. We use materials engineered to withstand constant moisture as well as those freeze-thaw cycles.
- Subgrade Preparation: As we mentioned, our soils in Seattle are unique. Knowing how to prepare that subgrade is important for a long-lasting job. This is true whether it is heavy clay or glacial till. You cannot just pave over problems. You have to fix them from the ground up.
