Our Roadway Prep & Base Work Capabilities

We handle every phase of roadway preparation — from the first cut to final grade — with the precision that comes from years of site work experience across the Kansas City metro.

Our roadway prep and base work services include:

Subgrade evaluation & proof-roll testing – Identify and correct weak or saturated soils before base placement.
Undercut & stabilization – Replace unsuitable material or strengthen it with lime, cement, or geogrid.
Aggregate base installation – Place, shape, and compact base rock to spec.
Fine grading & slope control – Establish crown, cross-slope, and smooth transitions for paving.
Drainage installation – Ditches, culverts, and catch basins to manage runoff and protect the base.
Final QC & paving handoff – Verified grades, compaction testing, and a clean site ready for asphalt or concrete.

ICON’s crews bring dependable scheduling, clean workmanship, and the right equipment to every job — ensuring each roadway passes inspection and performs for years to come.

FAQs

What’s included in roadway prep and base work?

We handle everything from clearing and subgrade stabilization to drainage, base installation, and final fine grading. You’ll receive a build-ready surface that meets paving specs.

How thick should my base be?

Most roads and driveways use 6–8 inches of compacted aggregate, depending on soil type and traffic load. We’ll verify design requirements before installation.

What’s a proof-roll, and why is it important?

A proof-roll uses a loaded truck or roller to test the subgrade for soft spots. It ensures the soil can support the pavement without future settlement or failure.

Do you install culverts and drainage structures?

Yes. Proper drainage is part of every project we do. We install and protect culverts, headwalls, and ditches to prevent erosion and base washout.

How long does roadway prep take?

Small drive approaches can be completed in a few days. Larger road or development projects typically take one to three weeks, depending on weather and scope.
