How to Build a Rock Wall With Mortar

If you are looking for a simple and quick way to create a rock wall, this article will walk you through the steps required. We’ll cover how to dry-lay the first course of both wythes and how to place drainage tile under the wall without preparing the drain. And we’ll cover how to protect your wall from trees. As always, you are never finished! Here are some helpful tips to help you along the way.

Dry-lay first course of both wythes

Start by laying the foundation footing for your rock wall. This will outline the front and rear faces of the wall and the first course of both wythes. The first course of both wythes should fit neatly between the bondstones at both ends. It is advisable to use smaller boulders or rubble for filling in the space between the stones.

If the stones fit tightly, dry-lay the first course of both wythes before setting them in mortar. When setting the stones, be sure to furrow the footing lightly. Apply one inch of mortar to the joints between the wythes. If you are building a large rock wall, keep the widest, flattest stones for the top course. You can also fill in the gaps between the wythes with smaller stones.

After the first course, you can lay out the second course using the same techniques as the previous one. Make sure to offset the joints in the second course to add strength to the rock wall. For irregularly shaped rocks, the face rock should be placed behind a large rock every three feet to give the wall some extra stability. Place small flat rocks as shims to prevent wobble.

To build a rock wall, you have to finish a substantial portion of each horizontal layer. This will ensure that the wall does not crumble because of faultlines. You can also use drainage gravel to fill the gap between the walls. However, be sure to make sure the gaps between the horizontal layers are not lined up. Failure to do so can lead to the collapse of the rock wall.

Check that all stones are level

Before you begin to build a rock wall, you should check that all stones are level. If they are not level, the weight of the stones above them will push them down and compromise the wall’s structural integrity. The stones should be positioned with their longest dimensions parallel to each other. This makes the walls look more stable. To make sure that all stones are level, use a mallet to tap the stones with a small amount of mortar.

When you’ve laid out the stones, you’ll want to make sure that they are dead-level from side to side and end to end. A spirit level will help with this step, but if you don’t have one, you can also use a clear plastic tube filled with water. Make sure that no bubbles are present in the water. Check that all stones are level before building a rock wall with mortar.

Once you’ve laid out the foundation for the wall, you’ll want to make sure the stones are all level. You can use a leveling wedge or smaller rocks to correct misaligned stones. Once the foundation is in place, lay out the stones. Make sure to leave about 18 inches of walking space between the foundation and the wall. Remember that it’s best to lay the thickest stones closest to the wall, and the thinner ones farther away from the wall.

After laying the first course, place the second course of stones. Make sure to angle joints backward, preferably a half-inch. Then, place the next course of stones, which should be offset by half an inch or more. You should place “deadman” stones every four feet to tie the wall to the ground. Remember to place deadman stones at least halfway up the wall so that the front and back of the wall will be level. A shorter wall will need one deadman course, and a taller wall will need two.

Protect your wall from trees

One way to protect your rock wall from trees is by covering the surface with a geotextile fabric. This type of fabric allows water to drain through and prevents larger objects from clinging to the wall. A string attached to a big nail can measure the distance of the wall from the base of the tree. Use this string to ensure that the topmost layer is not too far from the base of the tree. Once the foundation has been filled with the desired amount of material, it is time to install the second layer of stones.

To start laying the rock veneer, start by constructing the foundation. To lay the first layer, dig a trench that’s six to ten inches deep. This will plant the base into the soil and prevent the rocks from shifting over time. When laying stones, make sure to stagger the joints, which will help evenly distribute the weight of the stones and make the wall more stable. Afterward, place the larger stones on the bottom of the wall. Make sure that the stones are slightly tilted toward the back of the wall, as this will help the wall resist the weight of the backfill.

It is also essential to protect your rock wall from trees when building with mortar. Trees can cause a great deal of stress to your rock wall, especially if they are situated on sloped ground. In addition to increasing the weight of the wall, trees have highly invasive roots that can lift or even topple the structure. They can also sag or shift if the ground is unstable. Therefore, you must consider your future growth potential when designing your rock wall.

Place drainage tile under your wall without complete drain preparation

If you have a rock wall on your property, you can’t simply place drainage tile underneath it without complete drain preparation. Without proper preparation, water will pool around the wall and potentially move it. You can reduce the chances of this happening by installing a drainage pipe behind the rock wall. Make sure to install it far behind the wall to prevent erosion. You can also use pond liners or low-permeability clay fill in this area. You can even cover the drainage pipe with fabric.

When you place drainage tile under your rock wall without proper drain preparation, you’re also protecting your basement. It redirects water away from your home, making it less likely to flood. As our city grows, so does the amount of runoff and the frequency of severe weather systems. Regardless of the cause of the water coming into your basement, you’ll be saving money in the long run.

Check that your wall is strong and well made

If you are building a rock wall with mortar, it is important to make sure that it is made of sturdy materials. You should check that each rock has the proper size and weight to hold it up, as laying the stones too close together could weaken the structure. Moreover, it is better to break smaller rocks rather than placing them directly on top of large ones. In addition, the stones should be laid with a long dimension close to the horizontal so that the wall looks stable.

The rocks should be arranged in a manner that they will not be easily seen by others. You should not have visible “courses” of smaller rocks. The wall should be finished without any gaps or kinks, and the large rocks should extend into the next “course” of rocks. Afterward, you can put down the mortar and cement, and if you think that you have run out of space, change the orientation of the rocks.

Once you have done this, you can begin to place the base stones. Place them four inches off the ground, lining up the face with a stake. Then, place the next stones, alternating the big ones with the small ones. Make sure to tamp down each layer, as this will give the wall extra stability. To make the job easier, you can even sort the stones by size. You can also have children sort the rocks based on their size.

The rocks that you choose should be sturdy enough to hold back tons of weight. Five-pound rocks are not going to do much. You can also opt for concrete rocks instead of rocks, as the mortar will be able to support more weight. Ensure that the rocks are securely laid to prevent damage from falling rocks. If you fail to do this, your rock wall will break easily. If the rock wall fails to hold up, you can always use plywood or concrete for the construction.
