Curved Belgard retaining walls offer a visually appealing and functional solution for landscape design. The installation of these walls requires careful planning and execution to ensure their structural integrity and aesthetic appeal. In this article, we will discuss the key techniques involved in curved Belgard retaining wall Installation guide, providing a step-by-step guide for achieving successful results.

Site Preparation:

Before starting the installation process, it is essential to prepare the site properly. This includes clearing the area of any vegetation, debris, or rocks. Ensure that the ground is level and compacted to provide a stable foundation for the retaining wall.

Design and Layout:

The design and layout phase is crucial for creating curved Belgard retaining walls that harmonize with the landscape. Use a flexible hose or string to mark the desired curve on the ground. This step allows you to visualize the wall’s placement and make adjustments as needed. Take accurate measurements and create a scaled drawing of the wall design to guide you during construction.

Excavation and Base Preparation:

Excavate the marked area to the required depth, accounting for the base materials and the height of the wall. The excavation should extend beyond the wall’s footprint to provide space for base materials and proper drainage. Once the area is excavated, compact the soil and install a geotextile fabric to prevent the mixing of soil layers and improve overall stability.

Base Material Installation:

The base material is a critical component in supporting the weight of the retaining wall. Start by adding a layer of crushed stone or gravel, typically around 4-6 inches thick, to create a stable foundation. Compact each layer using a plate compactor to ensure proper settlement. Repeat this process until the desired base height is achieved, considering the wall’s design and specifications.

Wall Construction:

Begin by placing the first course of blocks along the marked curve, following the manufacturer’s instructions. Use a level to ensure that the blocks are aligned both horizontally and vertically. As you progress, install geogrid reinforcement every few courses to provide additional stability and prevent wall movement. Backfill each course with crushed stone and compact it thoroughly.

Cutting and Shaping:

Curved Belgard retaining walls often require cutting and shaping of the blocks to fit the desired curve accurately. Use a masonry saw or a diamond blade grinder to cut blocks as needed. Take precise measurements and make gradual cuts to ensure a precise fit. Always wear appropriate safety gear when using cutting tools.

Finishing Touches:

Once the wall is constructed, pay attention to the finishing touches. Use joint sand to fill the gaps between the blocks and prevent weed growth. Sweep the sand into the joints and lightly mist the wall with water to activate the binding properties of the sand. Clean any excess sand from the surface of the blocks to achieve a clean and polished appearance.

Drainage Considerations:

Proper drainage is crucial for the long-term stability of the retaining wall. Install a drainage system behind the wall, using perforated pipe and gravel. This will help redirect water away from the wall and prevent hydrostatic pressure from building up. Ensure that the drainage system slopes away from the wall and that the water has a clear path to escape.


Installing curved Belgard retaining walls requires careful planning, precise execution, and attention to detail. By following the steps outlined in this article, you can create visually stunning and structurally sound walls that enhance your landscape’s beauty. Remember to consult the manufacturer’s instructions and seek professional assistance if needed. With proper installation techniques, your curved Belgard retaining walls will provide years of functional and aesthetic appeal.
