How to build a retaining wall without mortar
If your backyard up in slope or if you need to reinforce a retaining wall, you might want to consider installing a natural stone wall. A wall of this kind can add value to your home while adding beauty to your garden design. You can install a wall of natural stone without using mortar. This is a dry stack technique.
Measure the wall area by taking the high and long. Multiply these two numbers to get the square footage (or square meters). Multiply the width of the wall to get the cubic (or cubic meters) feet from the wall. Instructs in a store garden rocks or stones you will use for the retaining wall, giving the steps you took. They will tell you how many tons of stones cover the specific number of square feet.
Board the stones . Start at the base of the wall. In principle digs a trench with shovel. For a wall less than 4 feet (1.20 m) high, dig a trench for the wall so that the first row is the top half of the second, in this case, about 2 feet (0 , 60 m). This will give an appearance of terraced wall and make your wall more stable. The trench should be deep enough to hold a layer of compacted gravel 6 inches (15 cm) and the ideal is that the depth of the trench is 10 inches (25 cm).
Pour gravel to 6 inches (15 cm) and then starts to flatten. Use a level to make sure it is uniform and flat. This will ensure that the base layer of stones large is level.
Starts building the wall putting stones larger at the base. This may take time because you have to make sure the installation is level in the base layer before proceeding stacking stones . Once you created the base layer, then you can stack the following levels. Use stones of medium size for the average level; then gradually, using the small dimension to the top. Place a few inches (cm) of gravel behind stone walls as you climb higher. Using a sod barrier to maintain the retained soil and to prevent the gravel wash.
Stack the rocks, gently tilting the slope to make sure it’s stable. You can do the test walking down the top to make sure it will not move, which could cause the stone wall to collapse later. Follow the basic rule for the construction of a stone wall: a rock sitting on two, then two rocks sit in one. This will ensure that the rocks are stacked properly. Check that the joints between the stones are not too large. Put a rock to block the path of the joints. Joints or spaces in the middle should be open to allow proper water drainage and to allow sufficient ground for the expansion of space behind the walls. Use a hammer and chisel to break the stones and fit properly.
Use the stones flat and smooth to cover the top of the retaining wall. This can be used to raise or for people to sit at the top of the wall.
