From first excavations to final finish work, we manage the essential early phases of residential and light commercial construction projects with attention to drainage, compaction, and structural longevity.

Professional Site Prep Services for New Construction

Before any building goes vertical, the ground must be properly prepared. Site prep is the critical first step to a successful project, and in Tacoma’s wet, uneven terrain, it’s not something to shortcut. We handle full site prep services including clearing, grading, excavation, and soil conditioning.

Land Clearing and Excavation

We begin by removing vegetation, debris, and old structures as needed. Excavation includes digging for foundations, utilities, and drainage systems, with attention to soil composition and sloping. For hillside lots or tight urban sites, we use precision grading techniques to maximize usable space.

Soil Stabilization and Compaction

After excavation, the site is stabilized through compaction to support the load of new structures. We assess soil type—clay, silt, or loam—and use proper moisture control and compaction equipment to prevent future settling or shifting.

Rough and Finish Grading

Rough grading shapes the lot for building pads and driveways, while finish grading fine-tunes slopes for drainage. In Tacoma’s rain-heavy climate, improper grading can cause water pooling or erosion. Our finish grading includes contouring to direct runoff away from structures.

Concrete Foundation Installation for Durable Structures

The foundation supports everything above it, and our team ensures that every pour meets structural engineering specs and city codes. We install a range of foundation types based on lot conditions and building design.

Slab-on-Grade and Stem Wall Foundations

For flat lots and new construction homes, we frequently install slab-on-grade foundations, which offer speed and cost efficiency. In areas with more complex grading or seismic considerations, stem wall foundations with crawlspaces may be more appropriate.

Reinforcement and Formwork

Before pouring, we install rebar or wire mesh to reinforce the concrete and prevent cracking. Our formwork ensures accurate dimensions, clean edges, and solid bonds between footings and vertical elements like foundation walls or piers.

Vapor Barriers and Insulation

To protect indoor spaces from Tacoma’s ground moisture, we install vapor barriers beneath slabs and apply rigid insulation when required. These steps are critical for homes with conditioned crawlspaces or slab-on-grade systems.

Flatwork Services: Driveways, Patios, and Walkways

In addition to foundations, we install high-performance flatwork that complements both residential and commercial properties. Our flatwork projects combine function with curb appeal and are built to last through freeze-thaw cycles and heavy rainfall.

Concrete Driveways and Parking Pads

We pour new concrete driveways and extend or replace aging ones across Tacoma. Our driveways are graded for drainage and finished to resist wear from vehicle traffic. We also install aprons, curbs, and parking pads as needed.

Backyard Patios and Slabs

From stamped patio designs to plain slabs for sheds and garages, our concrete patios are tailored for outdoor living and utility use. We also prepare subgrades to prevent cracking and heaving in Tacoma’s moisture-sensitive soil.

Walkways and Steps

We build entry walkways, garden paths, and concrete steps with careful attention to grade transitions, non-slip finishes, and long-term wear. These are often integrated into larger landscape or hardscape plans.

Retaining Walls and Structural Concrete Features

In Tacoma neighborhoods where elevation changes are common, retaining walls help prevent erosion and manage slopes. We build structural concrete walls that serve both functional and aesthetic purposes.

Gravity and Reinforced Retaining Walls

We design and build both gravity walls and reinforced concrete walls depending on height and soil pressure. Walls are engineered to support backfill and maintain grade separation on hillsides or raised lots.

Drainage Integration

Every retaining wall includes drainage systems to reduce hydrostatic pressure. This may involve gravel backfill, weep holes, or perforated pipe systems. Without these elements, Tacoma’s rain-heavy climate could compromise wall integrity over time.
