Natural Boulder Retaining Walls That Hold Real Grade.
Engineered boulder walls built to hold steep mountain hillsides — designed to look like they've always belonged on your property, not like a wall was dropped on top of it.
Built to Hold the Hill, Not Just Sit on It.
A retaining wall on a flat suburban lot and a retaining wall holding back a steep Teller County hillside are not the same project. Grade, soil, and drainage decide whether a wall lasts twenty years or fails in five.
We build with natural boulders — Pikes Peak Granite and other locally-sourced stone — set and battered into the hillside rather than stacked straight up, which is what actually lets a wall hold real grade over time.
Drainage is built into every wall, not treated as optional. Water trapped behind a retaining wall is the single most common reason walls fail, so backfill and drainage are part of the design from the first conversation, not something added if there's a problem later.
Walls are sized to the job — a low boulder border along a driveway is a very different build than a tall terracing wall holding back a hillside for a raised patio, and we'll tell you plainly if a project needs engineering review before we start.
Every wall is designed to work with the rest of your property, whether that's tying into a flagstone patio above it, framing a planting bed, or turning an unusable slope into a level, functional space.
How a High Point Retaining Wall Gets Built.
Site Walk & Grade Read
We assess the slope, soil, and drainage path before recommending a wall height and boulder size.
Excavation & Base
The wall base is excavated and set below grade so the first course of boulders has real footing, not loose soil.
Boulder Placement
Boulders are set and battered into the hillside course by course, with drainage backfill built in as we go.
Grading & Finish
Finish grading ties the wall into the surrounding landscape so it reads as part of the hillside, not an addition to it.
Frequently Asked Questions
How tall can a boulder retaining wall be?
It depends on soil, slope, and what's above the wall. Shorter walls are typically straightforward; taller walls holding back significant grade may need engineering review, and we'll tell you upfront if your project falls into that category.
Do retaining walls need drainage?
Yes, always. Water pressure behind a wall is the most common cause of failure, so every wall we build includes proper drainage backfill behind it.
Will a boulder wall survive Colorado's freeze-thaw cycle?
That's exactly what natural boulder construction with proper drainage is built for — it's a far more freeze-thaw-tolerant system than mortared block or poured concrete.
Can a retaining wall create usable flat space on a sloped lot?
Yes — terracing a hillside with one or more retaining walls is one of the most effective ways to turn unusable slope into a patio, planting bed, or level yard space.
