Control Erosion and Stabilize Sloped Ground

Retaining wall installation for residential properties in Derry

When your hillside yard sheds soil onto your driveway after every heavy rain, or your tiered garden beds collapse each spring, a retaining wall gives structure to the slope and holds back the earth where you need it most. TS Property Professionals LLC builds retaining walls in Derry using materials and methods suited to local soil conditions, elevation changes, and drainage patterns. Properties with steep lots or terraced landscaping depend on these walls to prevent soil movement, protect foundations, and create level areas for planting or outdoor use.

Retaining wall installation involves excavating the slope, compacting a gravel base, setting interlocking block or stone in level courses, and backfilling with crushed stone to allow water drainage behind the wall. The structure resists soil pressure from above while channeling runoff away from your home. Walls are commonly built along driveways, below patios, or to separate yard tiers on hillside properties throughout the region.

Details That Matter Most

You will see the crew excavate into the slope, lay fabric and gravel for drainage, and build the wall course by course with block or natural stone. In Derry, where clay-heavy soil retains water and shifts with freeze-thaw cycles, proper backfill and drainage are necessary to prevent wall movement over time. The base must extend below the frost line to avoid heaving in winter.

After installation, you will notice defined yard levels, stable soil that no longer washes down the slope, and improved usability of previously steep or eroded areas. TS Property Professionals LLC completes each wall with cap stones for a finished appearance and ensures water drains through weep holes or perforated pipe behind the structure. Retaining walls are built using durable materials suited for local conditions.

The crew uses excavators, compactors, levels, and hand tools to build walls up to four feet in height without engineering requirements in most residential settings. Taller walls or those supporting heavy loads may require structural design and permits. The service does not include decorative veneers, lighting, or plantings unless arranged as part of a broader landscaping project.

Before committing to a retaining wall, homeowners in Derry typically want to know about materials, drainage, and how long the structure will last.

What to Expect When You Book

What materials do you use for retaining walls?
You can choose interlocking concrete block, natural stone, or modular wall systems depending on budget and appearance. Each material is selected for durability and compatibility with local soil and weather conditions.
How tall can you build a retaining wall?
Most residential walls range from two to four feet in height. Walls taller than four feet may require engineering calculations, rebar reinforcement, and permits depending on local building codes in Derry.
What prevents water from building up behind the wall?
You will have crushed stone backfill, perforated drainage pipe, and weep holes installed to allow water to pass through the wall rather than pushing against it. This prevents pressure buildup and wall failure.
When should I install a retaining wall?
You should schedule installation when you notice soil erosion, washouts after rain, or when planning yard grading or patio construction on a sloped property. Walls are best built during dry weather for stable soil conditions.
Why does frost line depth matter?
Your wall footing must sit below the frost line to prevent the base from heaving when soil freezes and thaws. In Derry, that depth is typically 36 inches, ensuring long-term stability.

A well-built retaining wall stops erosion, defines yard tiers, and protects structures below the slope from soil movement and water damage.
