High-Strength Concrete by Legacy General Contractor
HIGH-STRENGTH CONCRETE — 5,000-10,000+ PSI FOR STRUCTURAL & HEAVY-LOAD APPLICATIONS
High-strength concrete (5,000-10,000+ PSI compressive strength) is engineered for applications where standard concrete can't meet structural demands. We pour high-strength foundations, heavy equipment pads, industrial floor slabs, and specialized structural elements. High-strength mixes use lower water-cement ratios, supplementary cementitious materials (fly ash, silica fume), and specific admixtures to achieve target strengths.
Starting at $12 per sq ft

Structural High-Strength Concrete
Concrete mixes exceeding 6,000 PSI for structural columns, beams, bridge decks, and high-rise construction.
Learn MorePost-Tension Concrete
Post-tensioned slabs and beams using steel tendons stressed after concrete cures. Longer spans, thinner sections, fewer cracks.
Learn More5 Highlights on High-Strength Concrete
Structural applications
high-rise foundations, bridge elements, and heavy-load bearing structures requiring exceptional compressive strength.
Industrial applications
heavy equipment pads, industrial floor slabs, and machine foundations designed for concentrated loads.
Engineered mix designs
lower water-cement ratios, supplementary cementitious materials, and specific admixtures for target strength.
Quality control
slump testing, cylinder testing, and mix verification ensure specified strength is achieved.
Why Choose Our High-Strength Concrete
High-strength concrete requires precise mix design and careful placement. We work with batch plants to develop mixes that reliably achieve target strengths.
Higher-strength mixes have different working characteristics — shorter working time, higher heat of hydration, and tighter curing requirements. Our crews are experienced with these demands.
Signs You Need High-Strength Concrete
1. Engineering specifications require high PSI
When structural drawings call for 5,000+ PSI concrete, you need a contractor experienced with high-strength placement.
2. Heavy concentrated loads
Equipment pads, machine foundations, and industrial racking supports often require high-strength concrete.
3. Reduced member sizes needed
High-strength concrete can achieve required capacity in thinner sections, saving material and space.
Our High-Strength Concrete Process
Step 1 — Mix Design
Work with batch plant to develop mix achieving target strength. May include fly ash, silica fume, and high-range water reducers.
Step 2 — Trial Batching
Produce and test trial batches to verify mix achieves required strength before the pour.
Step 3 — Placement
Place concrete with careful vibration and rapid finishing. High-strength mixes have shorter working times.
Step 4 — Curing
Extended wet curing or curing compound application. High-strength concrete benefits from longer cure periods.
Brands We Use

- Sika — high-range water reducers and admixtures
- BASF MasterBuilders — concrete admixture systems
FAQs About High-Strength Concrete
What makes concrete "high-strength"?
High-strength concrete typically exceeds 5,000 PSI compressive strength (standard concrete is 3,000-4,000 PSI). It's achieved through lower water-cement ratios, supplementary cementitious materials, and sometimes specialized aggregates.
Does high-strength concrete cost more?
Yes. High-strength mixes cost more per cubic yard due to additional cementitious materials, admixtures, and quality control testing. The cost is offset by the ability to achieve structural requirements in smaller sections.
