Services
Retaining Wall Construction
We design and build custom retaining walls using durable materials like basalt rock and concrete blocks. Our structures prevent soil erosion, manage water drainage, and create functional outdoor spaces. Each project incorporates geotechnical engineering principles to ensure stability in Seattle's wet climate while enhancing property value through aesthetically pleasing designs.
Rock Wall Installation
Natural rock retaining walls combine functionality with visual appeal. We source high-quality basalt from local quarries and use specialized equipment to install walls that resist weather damage. Our techniques include proper drainage systems with perforated pipes and gravel backfill to prevent structural failures in challenging Western WA terrain.
Artificial Turf Landscaping
Our low-maintenance artificial turf solutions provide year-round greenery with proper drainage systems. Installed by experienced professionals, these surfaces eliminate mowing and watering needs while withstanding Seattle's climate. We offer customizable designs for residential and commercial properties with allergen-free, pet-friendly options.
Emergency Wall Repairs
We address urgent retaining wall failures 24/7, stabilizing compromised structures to prevent safety hazards. Our rapid response team uses heavy equipment to repair leaning, cracked, or collapsed walls while implementing permanent drainage solutions. Temporary safety measures and permit assistance ensure code-compliant, long-term fixes for critical failures.
Hardscaping Services
Custom hardscaping transforms outdoor spaces with patios, walkways, and steps using pavers, stone, and concrete. Our designs integrate with natural landscapes while addressing drainage needs. We combine aesthetic appeal with structural integrity to create durable, weather-resistant outdoor living areas tailored to Seattle's climate conditions.
