DOT-Approved Concrete Additives: How to Get Self-Healing Systems on a QPL
State Departments of Transportation evaluate concrete additives against a defined set of performance, compliance, and traceability criteria before they appear on a Qualified Products List (QPL). For self-healing systems, the bar is higher: engineers need durability evidence, batch-plant compatibility data, and a manufacturer documentation package that holds up under procurement review.
Stonix supplies the full evaluation package for Basilisk self-healing concrete and routes approved specifications through the Stonix Certified Network so contractors can source product locally once the system is qualified.
What state DOTs require for QPL inclusion
Although wording varies by state, the evaluation package is broadly consistent:
- Manufacturer Declaration of Performance (DoP) and EN 934-2 or equivalent admixture certification
- Factory Production Control (FPC) manual demonstrating batch consistency
- Independent third-party test data on permeability, crack-sealing, and chloride diffusion
- Compatibility statements with common SCM blends (fly ash, slag, silica fume)
- Field installation references on comparable infrastructure assets
- Dosage and QC procedures suitable for ready-mix batching
How Basilisk meets the DOT documentation bar
Basilisk Healing Agent ships with CE certification under EN 934-2, a current DoP, an FPC manual, and electrochemical analysis reports covering reinforcement corrosion onset. Field references span European bridge decks, water-retaining structures, and US pilot programs.
Stonix consolidates these into a single submittal package and pairs it with a draft specification clause engineers can drop directly into the durability section.
The Stonix specification pathway
Most DOT QPL additions follow a four-step path: pre-submittal review, product evaluation, field trial, and listing. Stonix supports each step with technical documentation, a project engineer point of contact, and certified-dealer logistics through CRC Global so trial-batch deliveries arrive on schedule.
Once a state QPL adds the system, recurring specification on subsequent projects becomes the default — the durability and lifecycle-cost advantage compounds across the agency's program.
Frequently asked questions
Which state DOTs have evaluated Basilisk?
Evaluation status varies by state and is updated continuously. Contact Stonix with your state and project type and we'll confirm current status and supply the submittal package.
Does the additive require a special ready-mix process?
No. The healing agent is dosed at the batch plant alongside standard admixtures. Mix design, placement, finishing, and curing follow normal practice.
Who supplies product once a project is approved?
Stonix routes orders through the regional Stonix Certified Dealer with CRC Global logistics out of Kenner, LA — protecting territory exclusivity and guaranteeing delivery to the project site.
