Stone Work in King of Prussia, PA
Crushed Stone and Natural Stone That Finish Your Property Right
Not all stone behaves the same underfoot, since clean stone such as AASHTO No. 57 drains freely while a dense-graded 2A modified blend contains fines that compact into a firm, locked base. Richard Cooper's All Around Asphalt provides stone work in King of Prussia, PA, including crushed stone driveways, stone top-offs, retaining walls, walkways, decorative borders, and drainage stone. We complete stone projects for property owners in Sinking Spring, Reading, Phoenixville, and Pottstown.
With 16+ years of working stone into driveways, bases, and drainage systems, we know which material belongs where and why. Our crew grades each area with a skid steer, places stone in compacted layers, and shapes edges so surfaces hold their form through rain and plowing. You get practical recommendations on stone type, depth, and layout that suit how each space is used. Contact us through our contact page to request a free estimate for your next stone project.

Custom Stone Work We Install
Crushed Stone Driveways
Stone driveways are built with a compacted base layer and a durable top course that resists rutting and washouts. Proper crowning and edge definition help rain run off, keeping the surface firm and usable for years with only occasional maintenance.
Stone Driveway Regrading and Top-Off
Over time, stone gets pushed aside by tires and plows, leaving ruts and bare spots. The driveway is regraded to restore its crown, potholes are filled, and a fresh layer of stone is spread and compacted across the surface.
Stone Retaining Walls
Retaining walls hold back soil on sloped properties, creating level areas for lawns, patios, or parking. Proper footings, drainage stone behind the wall, and solid construction prevent the bulging and leaning that affect poorly built walls after a few seasons.
Walkways and Stone Paths
Paths of flagstone, stepping stones, or compacted gravel connect driveways, entrances, and outdoor spaces. A well-prepared base keeps each piece stable and level, reducing tripping hazards and making walkways comfortable for guests and family in all kinds of weather.
Decorative Stone Borders
Stone borders define driveways, flower beds, and walkways while protecting edges from erosion and mowers. Borders along asphalt driveways also help support pavement edges, reducing crumbling where the surface meets softer soil or grass. They also keep mulch off the pavement.
Drainage Stone and Landscape Rock
Clean stone placed in swales, around downspouts, or along foundations helps water drain and slows erosion. Landscape rock also offers a low-maintenance alternative to mulch in areas where runoff would otherwise wash lighter materials away. It also stays put through heavy storms.
Why Choose Us for Stone Work
Using the wrong aggregate leads to loose surfaces, poor drainage, or stone that washes away. Matching material to purpose, whether base, top course, or drainage, gives you a result that performs as intended on your property instead of needing rework.
The Right Stone for Each Job
Stone dumped and spread loosely shifts, ruts, and thins quickly. Placing material in layers and compacting each one creates a dense surface that resists movement, holds up to heavy tires and plows, and needs far less maintenance season after season.
Compacted Layers That Stay Put
Water sitting on a stone driveway softens the base and carries material away. Shaping the surface with a slight crown and proper side slopes moves rain off quickly, keeping the driveway firm and reducing washouts after heavy storms.
Crowned and Graded for Runoff
Hydrostatic pressure from saturated soil behind a retaining wall is what pushes many walls over. Including drainage stone and outlets behind each wall relieves that pressure, helping the structure stay straight and stable through wet seasons and winter freezes.
Walls Built With Drainage in Mind
A well-built stone base can later serve as the foundation for asphalt. Constructing stone driveways to proper depth and compaction now makes future paving simpler and more affordable if you decide to upgrade the surface down the road.
A Future Paving Option
Stone that spills into lawns and beds looks unfinished. Defined edges, borders, and careful grading keep material where it belongs, giving your property a tidy appearance and reducing the time you spend raking stone back into place after storms and plowing.
Neat Edges and Clean Finishes
Frequently Asked Questions
What type of stone is best for a gravel driveway?
A dense-graded blend like 2A modified works well as a base because its fines compact tightly. Many driveways use a crushed top course for traction and drainage. Richard Cooper's All Around Asphalt recommends blends for King of Prussia, PA driveways.
How often does a stone driveway need new stone?
Most gravel driveways benefit from a top-off every few years, depending on traffic, slope, and snow plowing. Signs you need more stone include exposed base layer, ruts that hold water, and edges where material has been pushed into the lawn.
Why does a gravel driveway wash out?
Washouts happen when water runs down the driveway instead of off to the sides, carrying stone with it. Missing crown, steep slopes without diversion, and loose, uncompacted material all make the problem worse, especially during heavy spring and summer storms.
What is 2A modified stone?
It is a crushed stone blend that mixes larger pieces with smaller chips and fine stone dust. That range of sizes lets it compact into a dense, stable layer, which makes it a popular base under driveways, patios, and walkways.
Can stone borders help protect asphalt edges?
Yes. Asphalt edges crumble when soil beside them erodes or softens. A compacted stone border provides lateral support and drains water away from the pavement, helping the edge hold its shape and reducing the cracking that starts along unsupported borders.
How do retaining walls handle water behind them?
Well-built walls include drainage stone behind the face and a perforated pipe or weep openings at the base. Richard Cooper's All Around Asphalt, with 16+ years of stone work in King of Prussia, PA, builds walls that let water escape.
Can a stone driveway be paved later?
Absolutely. A properly compacted stone driveway can serve as the base for future asphalt, often needing only regrading, some additional stone, and compaction before paving. Building the stone layer to the right depth from the start makes that upgrade easier.
What is the difference between crushed stone and river rock?
Crushed stone has sharp, angular faces that lock together under compaction, making it ideal for driveways and bases. River rock is rounded from water, so it rolls and shifts, which suits decorative beds and drainage areas better than traffic surfaces.
