Not every pour calls for standard concrete. Structural work demands high-strength formulations. Thin slabs benefit from fiber-reinforced matrices. Time-critical repairs need rapid-set chemistry. Abbotsford Concrete batches custom mixes to your engineer's exact specifications, with full documentation for audit and compliance. Free written quote on every order.
Every concrete project has a reason. Structural columns need compressive strength far beyond typical residential pours. Thin overlays and decorative work benefit from fiber reinforcement that controls cracks without traditional rebar. Industrial floors with tight production schedules demand rapid-set formulations that reach service strength in hours instead of days. Chemical environments, freeze-thaw cycles, and specialized applications all call for custom mix designs that standard ready mix cannot provide.
We work from the engineer's specification, not from guesswork. The mix is designed to hit the target, batched with calibrated equipment, and documented for structural review. When the spec says high-strength, we deliver high-strength. When fiber-reinforced is called for, the fibers go in at the right dosage. This is not a substitution game; it is engineering.
We receive the mix design requirements: compressive strength target, slump, air content, admixtures, fiber type and dosage, set time, and any testing or documentation the project requires.
Design and batch at the plant
The mix is formulated to the spec using calibrated scales and verified proportions. Batch records are created in real time, capturing every component and timestamp for the audit trail.
Load and deliver to the pour
Concrete trucks carry the batch records, mix design, and any test cylinders to the job site. Placement happens on schedule with the crew or pump operator as coordinated.
Compile documentation for closeout
Mix design, batch records, delivery logs, and test results are assembled into a complete package that supports the engineer's final sign-off and project compliance.
Why it matters
The Specification Is the Contract
Substituting standard concrete for high-strength fails the structural design. Using standard set time when rapid-set is specified can cause cracking from hydration mismatch. Omitting fibers when they are engineered into the slab compromises crack control. The specification exists because the engineer has calculated what the concrete must do. We supply to that specification without deviation.

High-strength, fibers, rapid-set, custom mixes and documentation.
Concrete with compressive strength well above standard ranges, typically for structural columns, precast elements, or engineered applications. The engineer's spec defines the strength target; the mix design is built to hit it with appropriate testing.
Crack control through synthetic or steel fibers distributed in the matrix, sometimes replacing or supplementing traditional rebar for thin slabs, overlays, and decorative pours. The fiber type and dosage match the engineered spec.
When the pour has to return to service much faster than standard concrete allows, road repair under traffic, runway repair, industrial floors with short shutdown windows. Rapid-set chemistry is different; the mix design accounts for that.
Yes, when the project requires laboratory verification. Test cylinders are cast at the pour, cured per spec, and delivered to the specified testing lab for compressive strength verification at the schedule the engineer requires.
Mix design, batch records, delivery times, test cylinder logs where applicable. The package supports structural audit and compliance review; it is part of the project deliverable, not an extra.
Client reviews
What Abbotsford Engineers Say About Specialty Mixes
High-strength mix for a residential pool deck structural slab. Spec'd, supplied, documented with test cylinders. Cylinder breaks confirmed strength. Real structural ready mix.

Structural Engineer, Abbotsford
★★★★★
Fiber-reinforced mix for a thin-slab overlay where rebar would have been unfeasible. Crack control through the fibers has held perfectly two years in. The engineering match was exact.

★★★★★
Rapid-set mix for a floor repair during a planned 24-hour shutdown. Concrete reached service strength in time for the production restart. Saved real operating cost.
Q. R5
Industrial Operations, Mission
★★★★★
Custom mix design for a chemically-resistant slab. They worked with our spec rather than substituting closest standard. Documentation supported the final engineering signoff.
