Introduction

Hardscape features like patios, retaining walls, and walkways can dramatically improve how a property looks and functions. When installed properly, these structures should last decades. But over the years, we’ve seen many situations where a project that looked great initially begins to fail much sooner than expected. In most cases, these failures aren’t caused by the visible surface material. The real issues usually happen beneath the surface, where base preparation, drainage, and soil conditions are inadequately prepared.

Here are some of the most common hardscape problems homeowners encounter—and why they happen.

Sinking or Uneven Patios

One of the most frequent issues we see is patios that begin to sink or become uneven over time. This typically happens when the base beneath the patio wasn’t excavated deeply enough or properly compacted during installation. Over time, soil movement and moisture can cause the ground beneath the patio to settle.

Homeowners may notice:

• Uneven pavers or stones
• Trip hazards or shifting surfaces
• Water pooling in low areas

Often the surface materials themselves are still perfectly good—the problem lies in the foundation underneath.

Cracked Hardscape Surfaces

Cracks are another common issue, especially with large continuous surfaces like poured or stamped concrete. Temperature changes, moisture in the ground, and seasonal freeze-thaw cycles can all place stress on outdoor surfaces. When the ground beneath a patio shifts or expands, rigid materials can begin to crack. Once cracks appear, they often grow larger over time as weather and soil movement continue to affect the surface.

Retaining Walls That Lean or Bow

Retaining walls are designed to hold back soil and manage changes in elevation across a property. Because they support significant weight, they must be installed with proper engineering and drainage.

When we see retaining walls beginning to lean, bow, or move forward, the most common causes are:

• Poor drainage behind the wall
• Insufficient base preparation
• Incorrect construction techniques

Water pressure building up behind a wall can gradually push it outward if proper drainage systems aren’t installed.

Drainage Issues

Water management is one of the most important—and often overlooked—parts of any hardscape project.
Without proper grading and drainage planning, water can collect beneath patios or behind retaining walls. Over time this weakens the base layers and contributes to shifting, settling, or structural problems.

Common warning signs include:

• Water pooling on patios
• Soil washing away near hardscape edges
• Moss or algae growth in certain areas

The Good News

Most hardscape problems are completely preventable when projects are designed and installed correctly. Proper excavation, base preparation, drainage planning, and experienced installation teams all play a major role in ensuring patios and outdoor structures perform well for many years. When those fundamentals are properly in place, outdoor spaces can provide long-lasting beauty and function with minimal maintenance.

At Borsello Landscaping, the goal is simple: build outdoor spaces that are designed correctly, built beautifully, and built to last.
Starting the planning process early helps homeowners stay ahead of rising costs while ensuring their project is completed on schedule.
