How Retaining Walls With Built-In Drainage Solve Slope Problems in Central PA

Reinholds, United States – July 8, 2026 / A Plus Landscaping /

REINHOLDS, PA – A large share of residential properties across Central Pennsylvania occupy sloped terrain. For homeowners in Lancaster, Harrisburg, Hershey, and surrounding communities, that grade is often the reason a backyard remains underused. Retaining wall installation addresses that challenge directly by stabilizing the slope and creating the conditions for the rest of the yard to function properly.

A Plus Landscaping, a family-owned design-build company based in Reinholds, has been constructing retaining walls throughout Central PA since 2006. The company works alongside homeowners to address both the structural and design dimensions of sloped landscapes.

Erosion Control

On unretained slopes, rainfall moves soil downhill. After repeated rain cycles or freeze-thaw events, that erosion becomes visible through rutted ground, exposed roots, and depleted topsoil. A properly constructed retaining wall holds the soil in place and interrupts that process at its source.

“Many homeowners treat a slope as a permanent limitation to their property, but a properly engineered retaining wall completely changes how a yard functions,” said Marcus Waldner, Founder of A Plus Landscaping. “In Central Pennsylvania, our severe freeze-thaw cycles put immense physical pressure on unmanaged soil. We don’t just build walls as standalone fixes; we integrate built-in drainage systems to protect the landscape structure while transforming unusable slopes into flat, functional ground built to last for decades.”

The wall serves as a physical barrier, redistributing the weight of the slope and keeping the soil profile stable across seasons. For Central PA properties, where frost depth and precipitation place consistent pressure on unmanaged grades, that structural function is a critical requirement rather than an optional feature.

Drainage Management

Retaining walls that lack adequate drainage develop serious structural vulnerabilities over time. Water accumulates hydrostatic pressure behind the wall face, which can cause displacement or complete structural failure. The drainage system positioned behind and beneath the wall units is just as important as the visible hardscape material itself.

Careful planning ensures that every retaining wall layout incorporates the necessary drainage components. That process includes specialized base materials, clean drainage aggregate placed behind the wall blocks, and a precise grading plan designed to direct water away from both the wall structure and the home’s foundation.

Design and Usable Outdoor Space

Landscape retaining walls produce flat ground, delivering a structural benefit that an open slope cannot provide. Level ground makes a patio installation viable, gives custom planting beds a stable foundation, and establishes defined tiers across a property to serve distinct functional purposes.

In Central PA, where properties frequently feature significant natural elevation changes, retaining wall installation is often the foundational project that makes subsequent renovations feasible. The design team approaches these wall structures as part of a connected outdoor environment rather than an isolated solution, ensuring the finished hardscape works alongside custom patios, paver steps, and softscape layouts.
