Stop Erosion and Stabilize Your Property

Excavation and site preparation for retaining wall installations in Wenatchee for residential and commercial properties.

When your property sits on a slope in Wenatchee, the ground is constantly moving downhill, especially during heavy rain or snowmelt. Without a retaining wall, you risk losing soil, damaging landscaping, or undermining structures like driveways, patios, or building foundations. FG Excavation LLC prepares sites for retaining wall installations by excavating the area, setting the grade, and ensuring the base is stable enough to support the wall and the soil behind it. The crew is experienced with hillside and sloped properties common throughout the Wenatchee Valley.

This service includes excavation for both functional and decorative retaining walls, supporting landscaping projects, structural support, and erosion control. The crew ensures proper drainage is built into the design so water does not build up behind the wall and cause shifting or failure. Whether you are adding a wall to level a yard, protect a slope, or create terraced planting areas, the preparation work determines how well the wall performs over time.

Preparing the Base for Long-Term Stability

Retaining wall preparation in Wenatchee begins with excavating the slope to create a level base and a trench for the wall's footing. The crew removes unstable soil and vegetation, then brings in compacted gravel to create a foundation that resists settling and shifting. Drainage systems such as gravel backfill and weep holes are planned during excavation to allow water to escape rather than building pressure behind the wall.

After the excavation is complete, you will see a level, compacted base ready for wall installation, with proper slope and drainage measures in place. The surrounding landscape is protected, and the prepared area is ready for block, stone, or poured concrete walls to be built on top.

The crew coordinates timing with your wall installer or landscaper and adjusts the excavation depth and backfill based on the type of wall you are building. This service does not include installing the wall itself, but it ensures the base is stable and drainage is handled correctly so the wall lasts for years without movement or failure.

What You Should Know Before Starting

Property owners in Wenatchee often have questions about retaining wall preparation, especially when dealing with steep slopes, poor drainage, or soil that shifts during wet weather.

What does excavation for a retaining wall involve?
Excavation includes removing soil to create a level base, digging a trench for the wall footing, and installing compacted gravel for drainage and stability. The crew also grades the slope and prepares the area behind the wall for backfill and drainage systems.
How does drainage prevent retaining wall failure?
Drainage allows water to escape from behind the wall instead of building pressure that can cause the wall to lean, crack, or collapse. Gravel backfill, weep holes, and perforated pipes are installed during excavation to manage water flow and protect the structure.
How long does retaining wall excavation take?
Most residential retaining wall excavations are completed in one to three days, depending on the length and height of the wall and the slope of the property. Larger or more complex projects may take longer, and the crew provides an estimate after visiting your site.
What happens if the soil is unstable or rocky?
The crew will adjust the excavation depth and base material to ensure stability. If rock is present, it may need to be removed or broken up, and additional gravel or engineered fill may be added to create a solid foundation.
Why is a compacted base important for retaining walls?
A compacted base prevents the wall from settling unevenly or shifting over time. Without proper compaction, the wall can lean, crack, or fail, especially during wet weather when the soil becomes saturated and heavy.
