Protecting Your Hillside Home: How Strategic Landscaping and Retaining Walls Prevent Foundation Damage in Dix Hills, NY
Dix Hills homeowners living on sloped properties face unique challenges that can threaten their foundation’s integrity over time. Erosion is public enemy numero uno when it comes to homes built on hillsides. It’s true, what goes up must come down. And, it is also true, what is already up is on its way down (no matter how slowly). Understanding how proper hillside landscaping and retaining wall design work together creates a comprehensive defense system against slope erosion and foundation damage.
The Hidden Threat: How Slope Erosion Damages Foundations
Every raindrop that falls on bare soil dislodges soil particles. As it gathers and runs down the slope, more soil particles are picked up. Multiply this by the duration of just one rainstorm and you quickly understand how easy it is to lose ground due to unchecked erosion. For Dix Hills residents, this process poses serious risks to foundation stability.
When it comes to having homes on hillsides, erosion is a significant concern for your home’s foundation. Of course, the biggest instigator of erosion is rain, as it bites into the soil and carries various debris such as rock and soil with it downhill. A slope applies more downwards pressure to the foundation than a home built on flat, solid land. In the worst-case scenario, unaddressed erosion-based foundation problems for homes on slopes can even pose a danger to those living there.
Strategic Landscaping: Your First Line of Defense
Effective erosion control begins with understanding how plants naturally protect soil. Plants are natural protectors of soil. They cloak the ground in foliage which prevents rain drops from falling directly onto soil particles. Instead, the plants diffuse the energy of raindrops so they filter down to the soil surface more gently.
The key lies in selecting the right plant combinations. Plant roots help to bind soils underground. Those species with a large proportion of fine roots that spread over a large area prove the best choices for slope stabilization. We chose a selection of deep-rooted ornamental grasses, native shrubs, perennials and ground cover for this hillside garden. Deeply rooted plants help stabilize the soil in the newly created garden terraces.
Successful hillside landscaping requires diversity in plant selection. The best planting design solutions include a diversity of plants. This ensures that should one species be threatened by pests or disease, there are plenty of others immune to the problem that remain to hold the slope. Long term studies have shown a well designed hillside garden planted in native plants has no measurable erosion. California native plants provide a low tech solution to slope management.
Retaining Walls: Engineering Foundation Protection
When natural landscaping alone isn’t sufficient, properly designed retaining walls become essential. A retaining wall is a structure designed to restrain soil to a slope that it would not naturally keep to, typically a steep, near-vertical, or vertical slope. These walls are built to resist the lateral pressure of soil, water, and other materials behind them. The primary function of a retaining wall is to prevent downslope movement or erosion and provide support for vertical or near-vertical grade changes.
For Dix Hills homeowners, retaining walls serve multiple critical functions. Retaining walls serve various purposes in both residential and commercial settings, including the following: Create level areas on sloped properties for landscaping or construction. Prevent soil erosion on hillsides. Manage water runoff and improve drainage. Protect foundations from sliding soil pressure.
The foundation of any retaining wall system is proper drainage. Most retaining walls fail because of pressure against the wall caused by water or soil-moisture build up behind the wall. Add a layer of gravel sloped one inch for every four feet to direct water away. Install a four-inch perforated PVC drainpipe at the base of the wall. This system helps channel water away from the wall, reducing the risk of soil saturation and pressure buildup.
Integrated Protection Systems
The most effective approach combines strategic landscaping with engineered retaining walls. We implemented a number of erosion control devices to make this hillside garden a success. First, we manipulated the grade and constructed terraces. was brought in, and retained with Ultratech Filter Socks. This terraced approach creates multiple levels of protection against erosion.
Additional erosion control methods enhance the system’s effectiveness. Wattles are long tubes filled with straw, compost, or coir that can be placed on slopes to slow down water flow and catch sediment. They are placed along the slope’s contour and staked into the ground to intercept runoff, reducing its velocity and allowing sediments to settle.
Professional Assessment and Installation
Given the complexity of hillside foundation protection, professional evaluation is crucial. Building retaining walls starts with site assessment and preparation. The slope is evaluated to determine the type of wall necessary, height, and thickness. The soil is also analyzed. Proper drainage systems must also be installed to avoid water accumulation that can cause damage to the wall.
