Armour Stone, 13 inch high


$550/skid is the price. On average, there are 10 pieces of this armor stone in a skid with an average length of about 2.5'. Each stone is 13 inches high; the length is random. The average cost of one stone is about $55+tax. On average, one armor stone weights 500-600 lb.The material to build each foot of a wall that is 13" tall will cost approximately $27 plus tax. This cost is estimated to help roughly calculate your spending on the material.

Armor stone retaining wall cost

How to calculate the cost of a retaining wall as a DIY project? Calculate the cost of the armor stone first. Let us presume you need 10 feet long and 26" high retaining wall. Every foot length of this material costs about $27. One 10-feet long layer of the armor stone will cost $27x10= $270 (+tax). As long as the stones are 13" high, two layers of them are required to build a wall that is 26" high, so the armor stone cost is doubled: 270x2= $520 (+tax).

Depending on your conditions, you may need other materials, like drainage stone or filtration fabric. Estimate how much of them are required and add to the cost. Also, add the cost of usage of equipment and any labor (if you hire somebody rather than doing all the job yourself). To calculate the cost of a retaining wall made of another wall stone, you need to know the approximate price of this stone per foot.

Usage of the armor stone for building walls

Due to the uniform heights of the rocks (about 13 inches), this material is perfect for building walls. The rocks are heavy enough (550-660 lb each) to make a heavy-duty and durable retaining wall, if built correctly.

When building a retaining wall, make sure that the filling material behind it drains quickly, otherwise heavy, wet back-fill will add pressure on the wall, and the wall fails. A layer of 3/4 clear stone behind retaining wall provides enough drainage in most cases. Still, this drainage stone needs to be protected from clogging, so cover the drainage stone layer with filtration fabric. Without filter protection, fine-textured soils will gradually accumulate between the pieces of drainage stone, and the drainage for the retaining wall fails. In the case of considerable water flow, use perforated drainage pipe wrapped into filter fabric.

Other usages of the armor stone

The large blocks of rock-faced limestone can be used in rock gardens, raised beds, or as accent stones in hardscape. This product is non-expensive and simple. Other kinds of armor stones are also available in our stone yard.
