Services
Concrete Design/Build
Our design/build service combines structural engineering expertise with construction execution to deliver cost-effective solutions. We collaborate with clients from concept through completion, utilizing BIM technology to identify potential issues before construction begins. This approach reduces change orders and ensures efficient project delivery while maintaining strict adherence to budget and schedule requirements.
Rebar Reinforcement
We operate two state-of-the-art rebar fabrication facilities producing project-specific materials year-round. Our advanced equipment and skilled crews ensure precise reinforcement for concrete structures. The integrated approach allows rapid response to potential issues while maintaining strict quality control standards throughout the fabrication and installation process.
Concrete Pumping
Our fleet of modern concrete pumping equipment handles challenging access requirements and time-sensitive projects. Certified operators utilize the latest technology to ensure precise material placement. The service includes specialized solutions for high-rise construction, underground applications, and complex site geometries while maintaining optimal safety standards.
Cellular Concrete
Our proprietary ConFoam cellular concrete provides a lightweight, self-compacting solution for void backfill applications. This cement-based slurry with entrained foam offers superior flowability and load-reducing properties. The material is ideal for pipeline abandonment, trench stabilization, and under-slab applications where traditional methods would be impractical or cost-prohibitive.
Shotcrete Application
We specialize in shotcrete placement for structural and architectural applications. Our ASA-certified nozzlemen apply concrete pneumatically to form complex shapes and surfaces. This method eliminates extensive formwork while maintaining structural integrity, making it ideal for retaining walls, slope stabilization, and sculptural elements.

CONCRETE PALACE
How would you review a contracting company? For this review I will rate it on the meeting areas, the customer-employee relation, the building, the parking and the office vibe. This building has multiple conference rooms in various sizes, from 8 people rooms to 30 people rooms. The meeting or conference rooms are well-lit, projector ready and well furnished. They have done a great job with them. The customer-employee relations are excellent. The front desk worker is always very positive and helpful. The building is a massive concrete palace. the gray walls wrap
