Retaining Wall Construction in Allerton
As a homeowner in Allerton, Illinois, you're likely no stranger to the challenges posed by our region's unique climate. The city's proximity to the Midwest prairie means it can experience sudden and intense rainfall events, which can lead to soil erosion and uneven terrain. A well-built retaining wall is essential to addressing these issues and maintaining a safe and beautiful outdoor space. Allerton's median home value of $106,700 and homeownership rate of 77.6% suggests that many residents take pride in their properties and invest in landscaping features like retaining walls.
Given the city's median year built of 1965, it's not uncommon for homes to have outdated or inadequate drainage systems. A retaining wall can help mitigate these issues by providing a barrier against water flow and creating level yard areas. The cost range for retaining wall construction in Allerton is relatively affordable, with prices starting at $3,000 and ranging up to $10,000. However, the final cost will depend on factors such as wall length and height, material type, drainage system requirements, and permit needs.
In Allerton's case, the city's rainfall average of 34 inches per year can lead to soil erosion in certain areas. A geogrid reinforcement is often necessary to stabilize the soil behind a retaining wall, especially if the terrain is particularly unstable or steep. With proper planning and execution, a retaining wall can be a valuable investment for homeowners looking to enhance their outdoor spaces while addressing common challenges like erosion and uneven terrain.

DIY vs. Call a Pro
Retaining walls under 3 feet tall are manageable DIY projects using interlocking landscape blocks. Excavate a level trench, add compacted gravel base, stack blocks with construction adhesive, and backfill with drainage gravel behind the wall.
Call a professional when:
Hire a professional for walls over 3-4 feet tall (may require engineering and permits), walls supporting structures, walls on steep slopes, or natural stone walls requiring skilled masonry.
