What Are River Rocks
Dried river beds are the primary source of river gravel or river rocks, commonly known as egg rock or pea gravel depending on their size. Rivers change course due to various natural and man-made factors, but are mainly caused by earthquakes and other tectonic activities which leave behind dried river beds.
The rocks in these riverbeds are then collected, washed, sized, and sorted in facilities using specialized equipment.
River rocks may come in a variety of colors such as tan, white, and brown. Usually, the colors are a mix of assorted earth tones.
Different Types of River Rocks and Their Sizes and Coverage
River rocks are categorized into different types depending on their size and coverage area. Here are the key details to keep in mind:
River Gravel #4: Also known as egg rocks, these river rocks are between ¼ inch and one ¼ inch. One ton of river gravel can cover an area of 100 sq ft at a depth of two inches.
Egg Rock #5: These egg rocks come sized between ¼ inch and one inch. One ton of these rocks covers an area of 100 sq ft at a depth of two inches.
River Rock (2 inches to 3 inches): These river rocks are larger, between two and three inches. One ton of these rocks covers an area of 80 sq ft at a depth of two inches.
River Rock (4 inches to 8 inches): Much larger still, between four and eight inches, these river rocks can cover an area of 50 sq ft at a depth of six inches. These rocks have an average thickness of six inches.
Pea Gravel: These are small pebbles, about the size of a thumbnail. One ton of pea gravel can cover an area of 100 sq ft at a depth of two inches.
What Colors Do Marietta River Rocks Come In
Marietta River rocks come in a wide range of colors, although they typically come in a variety of earth tones such as light brown, dark brown, tan, and beige. Pea gravel, used for walkway construction, tends to come in the same colors. However, unlike other river rocks, pea gravel may be white as well.
What are Marietta River Rocks
River rocks are generally used in outdoor landscaping for both their aesthetics and functionality. Primary applications for river rocks include creating a leveling base for making walkways or patios, erosion control, and even paving driveways. When purchasing river rock, never opt for pre-bagged options as they can be up to six times more expensive than the average bulk order from a supplier. Placing bulk orders can help to reduce the costs associated with landscaping, as well as ensuring you have an abundant supply available for all of your different projects and needs!
Decorative Purposes for Erosion Control
River rocks play a vital role in both landscape decoration and erosion control. Locations such as slopes, non-vegetated areas, and areas near naturally flowing water are more susceptible to water erosion, especially during periods of heavier rainfall.
River rocks installed at greater depths are better equipped to control erosion, while those used for decorative landscaping only tend to superficially protect the surface. When used strategically, marietta river rocks can effectively limit water flow, minimizing erosion.
Building Dry Creek Beds
Dry creek beds serve two purposes – giving a charming appeal to the yard, as well as water drainage. A dry creek bed mimics the environment of a natural riverside, complete with a river rock-lined trench and edged with small plants. These dry creek beds are an effective way to reduce runoff and prevent erosion. Did we mention that they look fantastic as well?
A stone-forged path instantly creates the impression of cute cottages and enchanting gardens, and you can add the same magic to your own yard by crafting a river rock walkway. While aesthetically pleasing, don’t forget to keep functionality in mind too. The larger the river rocks you use, the more difficult it is to walk across them. Ideally, egg rocks that are 1/4th inch or smaller are ideal for use in creating walkways. These smaller egg or river rocks may also go by the name pea gravel.
Substitute for Mulch/Bark
Marietta River rocks make an excellent substitute for mulch/bark. Not only do they increase the visual appeal of the soil and help retain its moisture, but river rocks are also better at preventing erosion as well. Unlike mulch or bark that require frequent replacement, river rocks can last several lifetimes with little maintenance.
