If your wall is built on a sand and gravel base, you can stack your stones up to 6 feet in height. A footing of gravel underneath it is necessary for any retaining wall construction to give the stones a solid base. It’s also one of the requirements mandated by a permit.
How high can you stack stones on a retaining wall? If your wall is built on a sand and gravel base, you can stack your stones up to 6 feet in height. A footing of gravel underneath it is necessary for any retaining wall construction to give the stones a solid base.
How durable is rock for a retaining wall? Rock for a retaining wall must be durable if you want it to last generations. Not all rock is the same. Some like granite and limestone can easily last for hundreds or thousands of years. Cold weather is rock’s enemy as water that seeps into tiny cracks can freeze and blast apart the rock over time.
How high can you build a retaining wall without reinforcement? It is also the stable height of most stand-alone stone walls. Sandy soil doesn’t absorb water, making it ideal for building a retaining wall without reinforcement. If your wall is built on a sand and gravel base, you can stack your stones up to 6 feet in height.
Why don’t cracks appear on a stacked stone retaining wall? Cracks don’t appear due to this natural give and take, unlike solid-piece walls constructed of stone and mortar. A stacked stone retaining wall relies on its own weight, its setback, leverage and the wall’s mass to stand up.

What is the best way to build a stacked stone retaining wall? The easiest way to build a stone retaining wall is to use the dry-stack method which requires no mortar between stones and does not need a concrete footing as mortared walls do. Dry-stack walls also drain well, allowing water to pass through the wall itself.
How much does it cost to build a stacked stone retaining wall? A natural stone retaining wall costs $2,000 to $10,000 on average or $10 to $85 per square foot. A boulder retaining wall costs $25 to $50 per square foot. A gabion retaining wall costs $10 to $40 per square foot. A dry-stack stone retaining wall costs $20 to $85 per square foot.
What are the benefits of a stacked stone retaining wall? The rugged beauty of a dry stack stone wall is reflected in the irregularity of its stones and rustic construction, reminders of the hand-built walls of the past. Built with no connecting “glue” or mortar, dry stacked stone walls have natural draining capabilities, allowing the water that builds up in the earth behind them to be expelled.
What is the maximum height for a stacked stone retaining wall? Three feet is the maximum recommended height of a stacked stone wall built on a clay surface. It is also the stable height of most stand-alone stone walls. Sandy soil doesn’t absorb water, making it ideal for building a retaining wall without reinforcement.
How high can you stack stones on a retaining wall?
What is the maximum height of a stacked stone retaining wall? As a general recommendation, the maximum height of a properly built stacked stone retaining wall is 5 feet under ideal conditions—the grade behind the wall is flat and the soil is sandy.
How high can you stack concrete blocks on top of each other? Without support, you can stack the blocks on top of each other up to around 4 feet, but there are other concerns above and beyond simple height that can affect the stability of the wall. While the 4-foot height cap is more of a recommendation than anything else, the type of soil you are dealing with will influence this number.
Can you build a retaining wall beyond 4 feet? For any wall that is over 4 feet in height, you should contact a structural engineer to test the soil and help you plan your block wall. Another aspect in determining if you can build a retaining wall beyond the 4-foot measurement is whether you have a footer in place.
How high should a retaining wall be on clay soil? If the soil behind and under your wall is clay, additional reinforcements are needed to support the retaining wall, regardless of height. Clay absorbs and holds water and can force your stones to move forward. Three feet is the maximum recommended height of a stacked stone wall built on a clay surface.
