Grading & Prep in Evansville & Newburgh, IN
The groundwork that determines whether your concrete lasts 5 years or 50.
Professional Grading & Prep Services
The most common reason concrete fails prematurely is not the concrete itself — it is what is underneath it. McCaslin Concrete Contractors provides professional site grading and subbase preparation services across Evansville, Newburgh, and the Tri-State area for residential and commercial concrete projects. Proper grading and compaction of the subbase are the single most important factors in determining how long your concrete will last and how well it will perform.
Our grading and prep work includes excavation to the correct depth, rough and fine grading to establish proper drainage slopes, placement and compaction of aggregate base material, and verification of compaction density. For projects on clay-heavy soils common in the Evansville area, we may specify additional aggregate depth or geotextile fabric to stabilize the subgrade and prevent soil migration into the base material.
We offer grading and prep as part of our complete concrete installation services and as a standalone service for builders, landscapers, and property owners who need site preparation for their own projects. Whether you need a driveway pad graded, a building pad prepared, or a backyard leveled for a patio, our crew has the equipment and expertise to get the base right. We also provide rough grading for new construction lots and final grading for landscaping projects throughout the Evansville and Newburgh corridor.
Why Choose Us for Grading & Prep
Prevents Concrete Failure
Proper subbase preparation prevents the settling, cracking, and heaving that result from poorly compacted or improperly drained foundations.
Drainage Engineering
We grade every surface to shed water away from buildings and prevent the pooling and saturation that undermine concrete from below.
Compaction Verification
We compact aggregate base material to specified densities, ensuring a stable platform that will not shift or settle under the concrete above.
Clay Soil Expertise
Southern Indiana's clay-heavy soils require special attention. We specify appropriate base depths and stabilization methods for the conditions at your site.

How We Handle Your Grading & Prep Project
Site Evaluation
We assess soil conditions, existing grades, drainage patterns, and depth requirements to develop the right preparation plan for your project.
Excavation & Rough Grade
The site is excavated to the specified depth and rough-graded to establish drainage slopes away from structures.
Base Placement & Compaction
Aggregate base material is placed in lifts and compacted to the required density. Geotextile fabric is installed if soil conditions warrant it.
Fine Grade & Verification
Final grading establishes precise elevations and slopes. The prepared surface is verified and ready for forming and concrete placement.
Grading & Prep FAQ
Concrete is strong in compression but has no ability to span voids. If the soil or base beneath a slab settles unevenly, the unsupported concrete cracks and breaks. Proper grading, aggregate placement, and compaction create a uniform, stable foundation that supports the concrete evenly for its entire lifespan. Skipping or shortcutting subbase prep is the leading cause of premature concrete failure.
We typically use #53 crushed limestone or a similar compactable aggregate base. The angular stones lock together when compacted, creating a stable, well-draining platform. The depth of base material depends on soil conditions and the intended use — typically 4 to 6 inches for residential and 6 to 12 inches for commercial or heavy-load applications.
Clay soil is common in the Evansville and Newburgh area and presents challenges because it expands when wet and shrinks when dry. We address this by excavating deeper, placing thicker aggregate bases, and sometimes installing geotextile fabric between the clay and aggregate to prevent soil migration. These measures create a stable base despite the challenging soil conditions.
Yes. While we most commonly perform grading and prep as part of a complete concrete project, we also offer standalone grading services for builders, landscapers, and property owners. This includes building pad preparation, lot grading, backfill compaction, and final grading for landscaping.
Grading and subbase preparation costs in the Evansville area vary based on the scope — from $2 to $5 per square foot for standard concrete prep to significantly more for large-scale lot grading or difficult soil conditions. When included as part of a concrete installation, prep costs are built into the project estimate. We provide free quotes for standalone grading work as well.
