What We Build
Every wall we build starts with the same fundamentals: engineered design, proper base preparation, drainage that works, and compaction done by the book.
Stackable Block Walls
Engineered mechanically stabilized earth walls built with stackable Keystone-style block systems. Geogrid reinforcement, proper drainage and compacted lifts deliver long-term stability on residential and private properties.
Timber Systems
Traditional timber retaining wall construction for smaller-scale grading and landscape needs. A cost-effective, clean-looking solution for terracing yards, planters and modest slope corrections.

Homeowner FAQ
Straight answers about wall systems, permits, drainage and project timing.
MSE walls use interlocking block, compacted backfill and geogrid reinforcement to create a durable system for larger grades and longer service life. Wood walls are a practical choice for smaller terraces, planters and modest slope corrections.
Permit requirements depend on the wall height, site conditions, location and local jurisdiction. We can help identify the requirements for your property and coordinate the right next steps before construction begins.
Many residential walls take several days to a few weeks, depending on the size, access, excavation, drainage, reinforcement and inspection requirements. We provide a project-specific timeline after reviewing your site.
Proper drainage is part of the system, not an afterthought. Depending on the project, that can include drain rock, perforated pipe, filter fabric and carefully compacted backfill to manage water and pressure behind the wall.
