Professional Retaining Wall Installation

Your Yard Works Like It Should

You’ll finally have a yard that doesn’t wash away every time it rains. No more watching your soil disappear down the slope, no more muddy patches where nothing grows, no more worrying about water creeping toward your foundation.

A properly built retaining wall does more than hold back dirt. It transforms problem areas into functional outdoor space you can actually use. Your landscaping stays put, your drainage works correctly, and your property value reflects the quality improvement.

The difference between a retaining wall that works and one that fails comes down to engineering and execution. When it’s done right, you forget it’s even there—it just quietly does its job year after year.

This isn’t about selling you the most expensive option. It’s about building something that actually works for your property and your budget.

Retaining Wall Design Process

Here's Exactly What Happens

First, we assess your property to understand the scope of the drainage or erosion problem. This includes evaluating soil conditions, measuring slopes, and identifying where water naturally wants to flow.

Next comes design and material selection. Whether you prefer natural stone, concrete blocks, or brick, the structural requirements remain the same. Proper foundation depth, drainage integration, and backfill techniques determine whether your wall succeeds or fails.

Installation follows proven engineering principles. Excavation to proper depth, compacted base preparation, systematic wall construction, and integrated drainage systems. The goal is a wall that handles both soil pressure and water management without compromising over time.

Final grading and landscape restoration ensures everything blends naturally with your existing outdoor space.

Stone and Concrete Retaining Walls

Materials That Match Your Vision

You get options that work with your home’s style and your maintenance preferences. Natural stone retaining walls offer timeless appeal and blend seamlessly with established Newtown landscapes. Concrete retaining walls provide clean lines and consistent appearance with minimal upkeep requirements.

Every installation includes proper drainage integration—French drains, weep holes, or drainage pipe systems depending on your site conditions. This prevents water buildup behind the wall, which is the primary cause of retaining wall failure.

The work includes all necessary excavation, foundation preparation, wall construction, backfilling with appropriate materials, and final grading. You also receive guidance on plantings and landscaping that complement the new structure while supporting long-term stability.

How deep does the foundation need to be for a retaining wall?

Foundation depth depends on wall height and soil conditions, but generally requires excavation to below the frost line—about 36 inches in our area. For every foot of wall height above ground, you need approximately 4-6 inches of foundation depth below grade. This ensures stability and prevents frost heave from shifting the wall over time. Proper foundation preparation also includes compacted gravel base and level setting, which are just as important as depth for long-term performance.

What's the difference between stone and concrete retaining walls?

Natural stone offers unique character and blends beautifully with mature landscaping, but requires more skilled installation and typically costs more. Concrete block systems provide consistent appearance, faster installation, and often better structural performance for taller walls. Both materials can last decades when properly installed with adequate drainage. Your choice usually comes down to aesthetic preference, budget, and specific site requirements. Either option works well in Newtown’s climate and soil conditions.

Do I need a permit for retaining wall installation?

Newtown Township typically requires permits for retaining walls over 4 feet in height or any wall supporting a surcharge load. Even shorter walls may need permits if they’re near property lines or affect drainage patterns. The permit process ensures proper engineering and protects both your investment and neighboring properties. Most residential landscape retaining walls under 4 feet don’t require permits, but it’s always wise to check with the township before starting work.

How long does retaining wall installation take?

Most residential retaining wall projects take 3-7 days depending on wall length, height, and site conditions. Simple garden walls might be completed in 2-3 days, while larger structural walls requiring extensive excavation and drainage work can take a week or more. Weather, access to the work area, and material delivery also affect timeline. You’ll get a realistic schedule during the initial consultation based on your specific project requirements.

What causes retaining walls to fail?

Poor drainage is the number one cause of retaining wall failure. Water buildup behind the wall creates pressure that eventually pushes the structure forward or causes it to lean. Inadequate foundation depth, improper backfill materials, and skipping drainage systems are other common problems. Frost heave, soil settlement, and using inappropriate materials for the site conditions also contribute to premature failure. Proper installation techniques prevent these issues from developing.

Can you repair an existing retaining wall that's failing?

Repair feasibility depends on the extent of damage and underlying cause of failure. Minor settling or cosmetic issues can often be addressed, but walls showing significant lean, cracking, or structural movement usually need complete replacement. Attempting to patch serious structural problems typically wastes money and delays the inevitable. During consultation, we’ll honestly assess whether repair makes sense or if replacement is the more cost-effective long-term solution for your situation.
