Beaverton Excavation Contractor

Experienced | Local | Excavation Company

Beaverton recently surpassed one hundred thousand residents, making it the Portland metro’s first suburb to reach that milestone, and that growth continues to drive excavation demand across the city. The underlying Tualatin Valley clay dominates most of Beaverton, creating soil conditions that challenge every excavation project from residential backyard work to large-scale commercial site development. Cooper Mountain on the southern edge adds basalt to the clay challenge, and the Fanno Creek corridor introduces high water table conditions through the city’s central and southern neighborhoods. Prodan Construction serves all of Beaverton with equipment and expertise matched to these varied conditions.

Digging Down and Building Up

Is your Beaverton building project complicated by the heavy clay soil that turns every yard into a quagmire during the rainy season? Do you need foundation excavation on a Cooper Mountain lot where basalt appears beneath the clay? Has your Beaverton home’s French drain system failed and needs complete replacement in uncooperative clay? Are you developing property near a Fanno Creek corridor and need to navigate the high water table? Does your Beaverton commercial site need grading and stormwater management designed for clay soil?

No matter your Beaverton excavation project, Prodan Construction brings the clay-soil mastery and versatile equipment that Oregon’s largest suburb demands. We work across every Beaverton neighborhood, from the transit-oriented areas near the MAX stations to the established homes of Sexton Mountain and the newer developments climbing Cooper Mountain. Our understanding of Beaverton’s soil and Washington County’s development requirements keeps every project running efficiently.

Landscape Grading, Sloping, and Site Preparation

Beaverton’s terrain ranges from the flat valley floor along Fanno Creek to the elevated slopes of Cooper Mountain, and our grading work covers both extremes. In the valley, we manage the heavy clay that is nearly impossible to work when saturated, timing projects carefully and using moisture management techniques to achieve proper compaction. On Cooper Mountain, we handle the transition from clay to weathered basalt, grading building pads and driveways where conditions change within a single lot. Our Beaverton grading services prepare sites for new construction, reshape existing properties for better drainage, and create level surfaces for the residential and commercial development that Beaverton’s growth demands.

Septic Tank and Field Excavation

While most of Beaverton connects to metropolitan sewer services, some properties on the southern and western edges, particularly near Cooper Mountain, may still use septic systems. Beaverton’s clay soil severely restricts percolation, making conventional septic design challenging. Prodan Construction installs septic systems in these clay conditions, working with engineers to select appropriate system types and excavating with the precision that functional installation requires. We handle the heavy soil and seasonal water issues that complicate septic work in Beaverton’s clay-dominated environment.

Trenching Contractor

Beaverton’s established neighborhoods need utility upgrades, and new development areas need complete utility infrastructure. Our trenching crews work through Beaverton’s clay to install and replace water, sewer, storm, power, and communication lines across the city. Beaverton’s clay makes trenching physically demanding, as the material must be precisely managed during backfill and compaction to prevent future settling. We restore all trench surfaces to city standards and ensure proper compaction in the clay fill that Beaverton’s soil requires. The ongoing development on Cooper Mountain drives additional trenching demand as new streets and utilities extend into previously undeveloped areas.

Excavating Foundations

Foundation excavation in Beaverton requires managing the clay soil that can expand, contract, and shift seasonally, creating the conditions that cause foundation problems in homes throughout the Tualatin Valley. Our crews excavate Beaverton foundations with proper overdig for drainage material, achieve the subgrade compaction specifications that engineers require in clay, and manage soil moisture during the critical construction window. On Cooper Mountain, we transition to rock excavation when basalt appears beneath the clay layer, using hydraulic breakers to reach specified foundation depths. Prodan Construction handles both Beaverton conditions with the equipment and expertise that consistent foundation quality demands.

Property Cleanup

Beaverton’s redevelopment activity, from Cooper Mountain new construction to infill projects in established neighborhoods, creates demand for property cleanup and site preparation. Our crews remove old structures, foundations, debris, and vegetation from Beaverton properties, preparing them for new construction. We handle the heavy clay soil during cleanup work, managing the material efficiently and grading cleared sites to proper drainage. Beaverton’s continuous development means cleanup and site preparation are a constant part of our work in this community.

Retaining Walls

Cooper Mountain drives much of Beaverton’s retaining wall demand, as the elevated terrain requires grade management for building sites, driveways, and yards. In the valley floor, retaining walls manage property transitions and create raised building areas above the water table. Our retaining wall excavation addresses both Beaverton zones, cutting foundations in clay with intensive drainage systems in the lowlands and working through basalt on Cooper Mountain’s slopes. Discover our retaining wall construction services and how we build durable walls adapted to Beaverton’s clay and basalt conditions.

We maintain excavators with clay-resistant bucket designs, wide-track machines that work on soft surfaces without sinking, and compaction equipment calibrated for the density requirements that clay subgrade demands. Our operators know the feel of Beaverton’s clay at various moisture levels and adjust their technique accordingly, from wet-weather approaches that minimize damage to dry-season methods that break through hardened material. On Cooper Mountain, we add rock-breaking attachments for the basalt that underlies the clay.
