FDOT Approved Aggregate Supplier in Florida: Base Rock, Rip Rap & Certified Materials
Florida Department of Transportation projects require aggregate from FDOT-approved sources. Spec deviations cause failed inspections, project delays, and costly material rejection. Delta Aggregate is an FDOT-approved aggregate supplier serving Southwest Florida, with a full product range covering base rock, rip rap, bedding stone, gabion basket stone, and construction sand — backed by the documentation your project submittals require.
Whether you're bidding an FDOT road and bridge contract, a water management district drainage project, or a coastal revetment under Army Corps permit, Delta Aggregate has the material and the paperwork to keep your project compliant and on schedule.
What FDOT Approval Means for Your Project
FDOT-approved aggregate must meet specific gradation, durability, and quality standards defined in the FDOT Standard Specifications for Road and Bridge Construction. Materials must come from sources listed on the FDOT Approved Products List (APL), and every delivery must be traceable back to the approved source.
Using a non-approved aggregate supplier on an FDOT project puts your contract at risk. Delta Aggregate maintains APL compliance and provides the documentation needed to satisfy FDOT inspectors and project engineers on submittal review.
FDOT Aggregate Products — Full Product Range
FDOT Base Rock
Base rock is the structural foundation layer beneath all paved surfaces on FDOT road and bridge projects. Proper gradation and compaction to specified density are required before any pavement can be placed. Delta Aggregate supplies base rock meeting FDOT Section 204 specifications for use on FDOT, county, and municipal paving projects across Southwest Florida.
FDOT Rock & Sand
Delta Aggregate supplies FDOT-specification rock and sand for a range of construction applications. Whether your project requires washed concrete sand, pipe bedding aggregate, or drainage blanket material, we can provide materials meeting the applicable FDOT specification with supporting test data.
FDOT C30 — Rip Rap Bedding Stone
FDOT Class C30 is the specified bedding layer material placed beneath all FDOT bank and shore rip rap installations. C30's gradation allows free drainage while preventing the upward migration of fines from underlying soil into the rip rap layer — a process called "pumping" that can destabilize a revetment over time.
FDOT C32 — Bank & Shore Rip Rap
FDOT Class C32 is the primary rip rap specification for bank and shore protection on FDOT drainage and waterway projects. Stone size and gradation are engineered to resist displacement under the design flow velocity and wave conditions specified for the project location. See how C32 is used in seawall rip rap repair and protection.
FDOT C34 — Gabion Basket Stone
FDOT Class C34 specifies the gradation for stone placed inside wire-mesh gabion baskets and gabion mattresses. The stone must fall within a size range that prevents escape through the mesh while packing tightly enough to minimize void ratio and maximize structural integrity.

FDOT Bedding Stone
FDOT bedding stone is used as a cushion and drainage layer for pipe installations, structural footings, and French drain systems. Delta Aggregate supplies washed stone meeting applicable FDOT pipe bedding gradation requirements, with delivery documentation for project records.
