Excavation Services & Site Preparation
Site preparation is the first and most critical phase of any construction project. At Aldana Construction, our excavation services in Central Illinois are built around precision, safety, and long-term project integrity. Whether clearing land for a new build, grading for proper drainage, or trenching for utilities, we deliver dependable excavation solutions tailored to the specific needs of each site.
As a local contractor with years of experience across LaSalle County, we understand the unique soil conditions, permitting standards, and drainage challenges of Central Illinois. Our comprehensive excavation and site prep services ensure your project begins with a stable, well-prepared foundation.
What Site Preparation Involves
Excavation and site preparation go beyond digging. It’s a calculated process that sets the stage for construction success. Proper site preparation accounts for soil type, drainage, access, elevation, and structural loads.
Each project starts with a site assessment and layout planning. This includes marking out structures, establishing final grades, and checking for underground utilities. Once plans are approved, we begin clearing, grading, and compacting as needed.
Debris Hauling
All waste and vegetation are transported off-site for proper disposal or recycling.
Structure Demolition
Before any construction begins, the land must be cleared of existing structures and debris. Existing concrete, fencing, sheds, or outdated buildings are dismantled and removed using safe demolition techniques.
Vegetation Removal
Before any construction begins, the land must be cleared of trees and shrubs. We remove trees, roots, stumps, and undergrowth to make way for new construction or hardscaping.
Site Grading and Elevation Control
Grading is one of the most important aspects of site prep due to the risk of water damage from improper slope. Our grading services are designed to manage surface water, prevent erosion, and ensure a solid platform for foundations or paving.
Rough Grading
This initial grading shapes the land to match elevation plans. It adjusts slopes and fills low areas, forming a basic layout for structures, roads, or parking lots.
Fine Grading
Performed just before construction, fine grading smooths the surface and prepares the subgrade for foundation forms, concrete pouring, or asphalt application.
Trenching for Utilities and Drainage
Aldana Construction provides precise trenching services for utility installation and site drainage. Trenches must be excavated to exact dimensions, with careful planning around frost lines and existing infrastructure. In central Illinois, where temperatures can cause pipe shifting or rupture, accurate trench depth and backfill are critical.
Utility Trenches
We excavate for water lines, electrical conduits, sewer pipes, and storm drains, coordinating with local utility providers for inspections and compliance.
Drainage Systems
French drains, culverts, and trench drains are installed to redirect surface and subsurface water away from structures.
Backfilling and Compaction
After installation, trenches are backfilled using approved materials and compacted to restore grade and prevent future settling.
Erosion Control and Soil Stabilization
Construction in central Illinois requires proactive erosion control, especially on sloped or loose soils. We incorporate preventative strategies into every excavation project.
Silt Fencing and BarriersSilt Fencing and Barriers
Temporary fencing helps contain sediment and protect nearby waterways or roadways.
Retaining Solutions
On steep grades, retaining walls or engineered slopes are built to prevent land movement and manage stormwater.
Stabilization Treatments
In high-traffic areas or loose soils, we apply lime, cement, or geotextile fabric to increase load-bearing capacity.
