How to Build a Limestone Wall How to Build a Limestone Wall
Building a limestone wall is a nice way to create a new sighting line in your garden. At the same time, it is a practical gardening application when creating large flowerbeds.
Words of Advice:
Keep in mind that there are many different types of soils and sands in the various climatic zones on the Earth. You need an adequate footing for the limestone wall in order to ensure it is stable in the long run. To determine the type of soil in your garden and the required footing, it will be best to consult with a local construction engineer. It is important to start your project well informed. The following simple guide will give you a general idea of how to complete your limestone wall project.
Step 1 - Level the Soil
Dig out an area in the garden where you will place the flowerbed. Shovel out the area in the desired shape, making sure that the place is well leveled. You have to shovel out all lumps in this area.
Step 2 – Lay the First Layer
Begin to place the limestone slabs so that you form the limestone walls of the flowerbed. Lay the slabs’ ends against one another but don’t use mortar or cement to hold them together. Build up the first level of the retaining wall. Use the power saw to cut the slabs down to size at the corners.
Step 3 – Build Additional Layers
Start laying the second level of the wall by placing the slabs in a brick-layering pattern. Once again, you need to cut the slabs’ ends down to size before you begin the third level. Keep on building layers until your wall reaches a height of at least 1 1/2 feet.
Step 4 – Lay a Sheet of Plastic
You need to place a sheet of plastic at the base of your flowerbed. The perfect height for the sheet is up to the midpoint of the wall. The sheet will eliminate leakages of soil and water through any cracks between the slabs.
Step 5 – Level out the Flowerbed
Use a pea gravel to level out the bottom of your flowerbed. The thickness of this layer has to be about 2 inches. In this way, if you plant flowers between the walls, you will prevent the leakage of excessive water down to the flowers’ root systems.
Step 6 – Plant Some Flowers of Your Choice
Fill in the remaining flowerbed potting soil. After planting flowers of your choice, you may consider covering the area with some cedar wood chips. The layer of cedar wood chips has to be level with the top layer of the retaining walls. You can now enjoy your first successful limestone project.
