  • Nicolock Certified Contractor

We follow industry best practices for excavation, base, drainage stone, and backfill so your retaining wall resists bulging, leaning, and movement. HL Design can design and build the perfect retaining wall for your property.

Leaning Wall, Erosion, or Wasted Slope?

If a wall is bowing, soil is washing out, or you simply have a hill you can’t use, it may be time to rebuild or redesign. We can remove failing or undersized walls, correct drainage behind them, and construct new retaining walls and seat walls that are properly engineered, attractive, and easier to maintain. We work with both residential and commercial properties across Frederick, Carroll, Howard & Montgomery Counties, MD.

Custom Retaining Walls in Mt. Airy, MD

Good retaining walls start with a solid plan. HL Design Landscaping looks at grades, soil conditions, drainage paths, and how you want to use the space above and below the wall. We then design wall lines, heights, steps, and any integrated seat walls so you gain usable, comfortable areas instead of just a steeper slope with blocks on it.
