Step 1: Planning and Design

Before diving into the construction process, proper planning and design are essential.

Step 2: Gathering Materials and Tools 

Once you have your design finalized, it’s time to gather the necessary materials and tools. Common materials for garden walls include bricks, stones, concrete blocks, or timber. Choose materials that match the aesthetic of your garden and provide the desired level of durability. Don’t forget to purchase essential tools such as a shovel, spirit level, trowel, masonry saw, and safety equipment. Consider renting or borrowing tools if you don’t have them readily available.

Step 3: Preparing the Site 

Prepare the site where the garden walls will be constructed. Clear the area of any vegetation, rocks, or debris. Mark the boundaries of the wall using stakes and string lines to ensure a straight and even construction. Excavate the ground to create a level foundation, removing any excess soil and ensuring proper drainage.

Step 4: Building the Foundation

A solid foundation is crucial for the stability of your garden walls. Begin by creating a trench that is wider than the width of the wall and deep enough to accommodate the foundation material. Typically, a minimum depth of 6-8 inches is recommended. Add a layer of compacted gravel or hardcore as a base, ensuring it is level. Install formwork or shuttering along the edges of the trench to contain the concrete mix. Pour the concrete into the trench, ensuring it is evenly spread and leveled. Allow the foundation to cure for the recommended time as per the manufacturer’s instructions.

Step 5: Constructing the Walls 

With the foundation in place, it’s time to start building the walls of your garden. Lay the first course of bricks or stones, ensuring they are level and plumb. Apply mortar between each brick or stone, using a trowel. As you progress, regularly check for level and plumb to maintain a straight and even wall. Continue laying courses, staggering the joints for stability and strength. Use a spirit level and a masonry saw to cut bricks or stones to fit around corners or curves. Leave space for any necessary drainage holes or weep vents to prevent water buildup.

Step 6: Finishing Touches 

Once the walls are complete, take the time to add finishing touches. This may include applying a sealant or waterproofing agent to protect  the walls, adding decorative elements such as coping stones or caps, or painting the walls to enhance their appearance. Consider incorporating planters or climbing plants along the walls to add greenery and soften the structure.
