Riverstone Highland Asphalt Paving is an asphalt paving contractor serving Grand Terrace, CA with parking lot maintenance, driveway paving, sealcoating, and crack sealing - covering every part of this small Inland Empire city from the neighborhoods near Barton Road to the sloped lots closer to Blue Mountain.
We have been working in the San Bernardino Valley since 2017, and we respond to new estimate requests within 1 business day.

Grand Terrace is a small city but its Barton Road commercial corridor has retail, service businesses, and city facilities that depend on well-maintained parking surfaces. Our parking lot maintenance program - covering sealcoating, crack sealing, and striping refresh - keeps Barton Road-area lots safe, compliant, and in good condition through the Inland Empire's extreme summer heat and winter rain cycles.
Most homes in Grand Terrace were built between the 1960s and 1990s, and many of those original driveways are now showing the effects of clay soil movement, decades of Inland Empire sun, and winter rain. We replace failed driveways with properly graded hot-mix asphalt, paying attention to drainage slope on the hillside lots near Blue Mountain where water runoff is a real consideration.
Grand Terrace sits at around 1,000 feet elevation, which gives it slightly cooler nights but still delivers the same intense daytime UV radiation that oxidizes asphalt across the Inland Empire. Sealcoating every two to three years blocks UV penetration, keeps the binder flexible through the temperature swings, and prevents the surface from becoming brittle before cracks open and water gets in.
The clay soils across Grand Terrace swell and contract with each wet-dry cycle, opening new cracks in driveways and parking lots every year. Routing and sealing those cracks before the fall rains arrive is the most cost-effective thing a homeowner here can do - it stops water from reaching the base and prevents the small cracks of today from becoming the failed sections of next year.
When a section of a Grand Terrace driveway or lot has failed at the base level, a surface-only patch will not hold. We cut out failed sections to the proper depth, rebuild the base, and install hot-mix material that bonds correctly and handles the soil movement common in this part of San Bernardino County. Properties on sloped lots require extra attention to drainage during repair.
Whether you need a new driveway on a residential lot off Barton Road or a small commercial surface at a local business, Grand Terrace's compact size means we can be on-site quickly without the long lead times that larger cities sometimes bring. We handle grading, base prep, and paving as a complete package so the finished surface drains correctly and lasts.
Grand Terrace covers only about 3.5 square miles, tucked between Blue Mountain to the east and the La Loma Hills to the west. That terrain means a meaningful share of the city's homes sit on sloped or graded lots where water does not naturally drain away from foundations and driveways the way it does on flat valley-floor properties. When asphalt or concrete work is done on those lots without proper attention to drainage slope, the first few winters reveal the problem in the form of water pooling, edge erosion, and accelerated cracking. A contractor who grades properly before paving - and who understands how water moves on Grand Terrace's hillside properties - is delivering something that actually matters for the long term.
The city's housing stock is mostly from the 1960s through the 1990s, which means original driveways and concrete flatwork are now 30 to 60 years old. The clay-heavy soils across San Bernardino County have been expanding and contracting under those surfaces for decades, and the seismic activity in the broader region adds occasional shaking that widens existing cracks. Inland Empire summers compound the problem: months of intense heat and UV radiation oxidize and dry out asphalt binder, making surfaces brittle before the winter rains arrive to exploit every crack. Staying ahead of that cycle with regular sealcoating and crack sealing is the only practical way to avoid premature replacement on a budget that most Grand Terrace homeowners recognize.
Our crew works throughout Grand Terrace regularly, and we understand the local conditions that affect asphalt paving work here. Grand Terrace is one of the smaller cities in the Inland Empire, incorporated in 1978, and most of our jobs here are residential driveways and the smaller commercial surfaces along Barton Road - the city's main street that connects Grand Terrace to I-215 and carries City Hall, local shops, and most commercial activity. When permits are required, we work with the Grand Terrace Building and Safety department. The city's permit and public works information is available through the City of Grand Terrace.
Grand Terrace borders Colton, CA to the north, and the soil and climate conditions are consistent across that boundary - the same clay soil patterns, the same seasonal cracking cycle, the same UV exposure. We regularly serve both cities in the same week. We also work in Loma Linda, CA, which sits to the east and shares the same Inland Empire valley conditions that drive pavement maintenance needs in this part of San Bernardino County.
Contact us by phone at (909) 737-6516 or submit the estimate form on this page. We respond to all Grand Terrace requests within 1 business day and schedule your on-site visit at a time that works for you.
We come to your property, assess the existing surface and base condition, and give you a written estimate with no obligation. For Grand Terrace properties on sloped lots, we note drainage considerations in the estimate so you know exactly what the job includes and what it will cost before we start.
We schedule your job and show up when we say we will. Most residential driveway jobs in Grand Terrace are completed in a single day. Larger parking lot maintenance projects may take two days depending on scope. You do not need to be present for the full duration once the work is underway.
When the job is done, we walk the site with you, explain any care instructions for the new surface - including cure times that vary with Grand Terrace's seasonal temperatures - and make sure you are satisfied before we leave.

(909) 737-6516Grand Terrace is a small, incorporated city in San Bernardino County, covering roughly 3.5 square miles between Blue Mountain to the east and the La Loma Hills to the west. The city incorporated in 1978 and has grown slowly, keeping the neighborhood feel that larger Inland Empire cities have lost over time. With around 13,000 residents, it is one of the more tightly knit communities in the area - a place where neighbors know each other and a local contractor who knows the streets actually stands out from a company driving in from across the county. Most of the housing stock is single-family, owner-occupied, and built between the 1960s and 1990s, giving Grand Terrace a consistent character of well-kept suburban homes on modest lots with concrete and asphalt flatwork that is now several decades old. You can read more about the city's history and community on the Grand Terrace Wikipedia article.
Barton Road is the main east-west street through Grand Terrace, connecting the city to I-215 and serving as the center of local commercial activity - City Hall at 22795 Barton Road, local shops, and service businesses are all found here. Mt. Vernon Avenue runs north-south as one of the few through-routes in the city's compact street grid. The community is close to both San Bernardino, CA to the north and Colton, CA, which borders Grand Terrace directly, and residents commute to both cities for work and services. Richard Rollins Community Park and Grand Terrace High School are two of the most recognizable landmarks for families who have lived here a while.
