In Ellettsville and throughout Indiana, drainage problems often start with improper water flow management. Clay-heavy soils, sloped terrain, and seasonal rainfall can quickly overwhelm undersized culverts or poorly designed drainage systems.
Alchemy Excavation provides engineering-led culvert installation and drainage improvements designed to control runoff, prevent erosion, and protect structures, driveways, and road entrances. Because most property damage begins with unmanaged water, proper design matters more than temporary fixes.
Southern Indiana properties frequently experience:
Without correct pipe sizing, slope calculation, and proper installation, drainage systems can fail during peak rainfall events.
Our approach focuses on:
Drainage improvement is not just pipe replacement — it is managing water movement across your property.
We design culvert diameter, slope, and invert elevation to move water reliably through storms—without constant cleanouts and repeat washouts.
We don’t just swap the pipe. We evaluate ditch grade, runoff patterns, and discharge performance to fix the root cause.
Proper bedding, compaction, stabilization, and erosion protection reduce settling, blowouts, and inlet/outlet failure.
If the crossing impacts ROW or a road approach, we plan accordingly based on jurisdiction requirements.
We work on driveway culverts, road crossings, ditches, stormwater improvements, and full-scale drainage systems for residential and rural properties.
Proper culvert and drainage design provides long-term protection:
Addressing water movement at the source prevents repeated repairs.
We provide culvert installation and drainage improvement services throughout:
All work is designed for the rainfall patterns and soil conditions of southern Indiana.
Culvert and drainage work often involves public right-of-way (ROW), particularly at:
Understanding permit requirements helps avoid delays or compliance issues.

Eliminate soggy yards, pooling, and recurring drainage issues.

Correct slopes, reshape ditches, and restore proper surface water flow.

Engineered drainage systems, including basins, swales, and flow correction.
Signs include driveway washouts, standing water at the entrance, crushed pipe sections, or visible erosion at the outlet. A site evaluation can determine whether replacement or regrading is necessary.
Common causes include undersized pipes, improper slope, soil settlement, debris blockage, and erosion around pipe ends. Proper installation and capacity planning prevent most failures.
Permit requirements depend on whether the work occurs within public right-of-way or connects to a public roadway. We can help guide you through local considerations.
Costs vary based on pipe size, length, soil conditions, and drainage complexity. We provide a detailed estimate after evaluating the site.
If you’re experiencing driveway washouts, ditch overflow, or standing water, addressing drainage early protects your property long-term. Contact Alchemy Excavation today to schedule a professional site evaluation and free estimate for culvert and drainage improvements in Ellettsville.
