Does your property have a sloped area that needs a retaining wall?
Have you considered a rock or boulder wall?
Boulders and rocks make gorgeous, sturdy retaining walls and have the ability to complement any outdoor landscape. Stone and boulder walls are comparative in pricing too typical brick masonry walls, and have the added ability of surviving the sands of time, almost to perfection. They give a natural look to any environment, with different colors and types of stones adding to the uniqueness of your home.
Retaining walls are intended to support soil, and deter erosion, an important component of sloped areas. They are also great multitaskers, and can serve as planters, seating areas, enclosures, surrounds, and even fencing.
There are two types of stone walls, mortared and non-mortared. Mortared walls have been constructed using wet mortar, to adhere the stones together and provide stability. Non-mortared walls are dry stacked with no mortar or other adhesive.
A dry stacked wall makes use of its own weight, as well as friction between stones, to hold back large amounts of soil. They are slightly tilted back to provide further support, and are carefully engineered once their height exceeds four feet. Boulder or rock walls have the capability of providing even better protection than their brick counterparts, and can be used for additional hardscaping such as terraces, stairs and planters.
Constructing a mortarless wall consists of more than just dry stacking stones, there are calculations and engineering specifications that go into it’s preparation and build. The stones must be fitted in a pre-planned method to allow for proper drainage and friction capability as well as natural occurrences of the mortar joints. Large stones or boulders work best, but you can certainly match the stone with the look of your outdoor environment, as well as your house to achieve a comprehensive look.
To construct the sub-surface base of a dry stacked retaining wall, either geofabric, or plant bases are used. The roots of plants provide excellent stability for walls and soil as well. Larger rocks can be set into the ground to use as a base for the wall, and also have the ability to withstand harsh weather and soil conditions.
River rock is a beautiful option for those who want a mortared retaining wall. River rocks are naturally different shades of gray and are usually smooth in places, with some rock completely smooth. A river rock retaining wall is constructed the same as other types of rock with larger anchor stones on the bottom, allowing for water flow, and smaller stones filling in the gaps.
There are various methods for sub-surface anchoring, but most don’t require more labor than a typical stone wall, and each will provide a solid foundation. River rock also allows for various design capabilities and can provide a beautiful tool for constructing patios, planters, or various other hardscape features.
Whichever type of stone or boulder wall you choose, you will have a gorgeous retaining wall to support your landscape, and beautify your outdoor living area.
