Can a dry stone wall be a retaining wall?
Using dry-stone walls to retain terraces in a sloping garden The Dry-stone method of building retaining walls to hold back soil when terracing a slope has been used for thousands of years. Almost all early retaining walls were built this way using stacked stone without any mortar to hold the retaining wall together.
Do you need foundations for a dry stone wall?
Dry stone walls are durable because they contain no mortar, but are held together by the weight of stone, and by the skill of the builder who selected and fitted the stones together. Fewer new walls are built, although foundations sometimes have to be relaid.
How do you support a dry stone wall?
To keep the wall stable, fill any gaps between the larger stones in each layer with small stones (filling stones), which help bind the wall together. As you build up layers, you will need to place some ‘through stones’ at regular intervals.
Does a 2 foot retaining wall need drainage?
These walls need a drainage system regardless of the wall height. If there are poor draining soils such as clay behind the wall, there needs to be drainage incorporated the wall system. Clay when wet is very weak, so it is essential to provide a way for water to escape from behind the wall.
How high can you build a dry stack wall?
Dry stacked stone walls are usually constructed against a hillside. Though, freestanding walls are stable up to about 3 feet in height.
Do I need a concrete footing for a retaining wall?
A buried structural footing is usually required for larger retaining walls. To create this, a landscaper pours concrete below frost level (the depth to which the ground will freeze during the winter). Footings poured too shallow are prone to shifting and moving if moisture in the soil freezes and heaves.

How Much stone do I need for a dry stone wall?
A dry stack rock wall uses gravel to fill gaps between the rocks in the wall. For example, if the wall length is 30 feet, the width is 2 feet and the height is 3 feet, the volume of gravel needed to construct this wall is 30 x 2 x 3 = 180 divided by 3 = 60 cubic feet.
Are dry stone walls strong?
It’s called a dry-stone wall (or, sometimes, a dry-laid wall) because, unlike a brick wall, it’s made by stacking stones without (wet) mortar to hold them together. Dry-stone walls are strong and attractive and can last hundreds of years.
How deep should a stone wall foundation be?
Choose Stones A mortar wall must be built on a firm foundation, or its joints will crack. Dig a trench about 6 inches wider than your wall. It must be deeper than the frost line, or at least 12 inches deep for a 3-foot-high wall. Tamp the gravel in the bottom of the trench, and pour at least 8 inches of concrete.
What stone is used in dry stone walling?
Dry stone walls use earth as a mortar. Dry stone walls can be made from slate, granite or other types of stone. Hammered granite is supplied as roughly broken blocks. The shapes vary and there is a degree of skill required to fit the stones together neatly when only earth is being used to bind them together.
How far apart should posts be for a retaining wall?
Retaining walls are a great solution for leveling out flat areas when you’re trying to landscape a hill. However, if you’re building one yourself, you may be wondering how far apart the posts should be. We’ve done the research and have the best answer for you. Retaining wall posts should be at least three feet apart.
How thick should a retaining wall be?
Retaining walls can be tricky to build as they need to be strong enough to resist horizontal soil pressure where there are differing ground levels. One of the things you must get right is the thickness of the wall. It should be at least 215mm thick and bonded or made of two separate brick skins tied together.
At what height does a retaining wall need to be engineered?
Most municipalities require a building permit and a design from a Licensed Engineer if your wall is taller than 4 feet high (measured from the bottom of the first block to the top of the last block).
WHY DO Retaining walls fail?
A retaining wall will fail when it is unable to withstand the force on it created by the soil behind it. Water is heavy, and as it builds up in the soil behind the wall the force acting on the wall dramatically increases. At some point, that force may exceed the capacity of the wall and cause the wall to fail.
Do I need rebar in a retaining wall?
A retaining wall must provide a way to release the water that builds up in the slope behind it. Retaining walls must be stronger than freestanding walls. Insert rebar in the footing when you pour it; this should be done at every three blocks or at intervals specified by your local codes.
