Every great structure starts with a strong foundation—and for most projects, that means a properly built concrete slab. At Wallace Construction, we engineer and install flatwork designed to resist Oregon’s challenging climate.
Concrete Slabs in Portland, OR and the Willamette Valley
Our team understands how Oregon’s moisture, soil types, and freeze-thaw cycles can affect pavement over time. T
That’s why we use proven techniques and high-quality materials to create slabs that stay level, resist cracking, and handle heavy use without shifting or sinking. Whether you’re building a new home, expanding a shop floor, or preparing a site for municipal work, our concrete slabs are made to stand the test of time.
Our team provides reinforced concrete slabs for a wide variety of applications:
- Residential: Foundations, garages, patios, and home additions
- Commercial: Warehouses, shop floors, loading areas, and equipment pads
- Municipal: Public walkways, park facilities, pump stations, and utility structures
Each slab is customized for its purpose: whether it needs to support heavy equipment, resist freeze-thaw cycles, or provide a smooth, level finish for interior flooring.
Our Concrete Slab Installation Process
We approach every project with precision and an engineer’s attention to detail. Here’s how we ensure long-lasting performance from the ground up:
- Site Preparation: The area is cleared, excavated, and compacted to create a stable foundation for the slab.
- Base Installation: A layer of crushed stone or gravel is added and compacted to prevent settling and improve drainage.
- Forming & Reinforcement: Forms are set to define the slab’s shape, and steel reinforcement (rebar or wire mesh) is installed for strength.
- Pouring: We pour high-strength cement and level it to exact specifications, ensuring consistent thickness and a smooth finish.
- Finishing & Curing: The surface is troweled or textured to meet the project’s needs, then cured properly for maximum durability and crack resistance.
Built for Oregon’s Climate
Oregon’s frequent rainfall and temperature swings can cause expansion, contraction, and moisture-related damage to poorly installed slabs. Our engineering-driven approach ensures every project accounts for drainage, expansion joints, and concrete mix design suited to the Pacific Northwest’s conditions. The result: long-lasting, stable slabs that resist cracking and shifting over time.
Wallace Construction: Proudly Serving the Pacific Northwest
Based in Portland, Oregon, we provide concrete paving across Beaverton, Tigard, Lake Oswego, Scappoose, and the greater Willamette Valley. Our local experience means we understand the soil, drainage, and weather conditions unique to this region—and we build accordingly.
