Central Pennsylvania's freeze-thaw cycles, which place immense physical pressure on unmanaged soil, are driving demand for engineered retaining walls, according to A Plus Landscaping, a family-owned design-build company based in Reinholds that has been constructing retaining walls throughout the region since 2006.
Many residential properties in Lancaster, Harrisburg, Hershey, and nearby communities are built on sloped terrain, often leaving backyards underused. Retaining wall installation addresses this challenge directly by stabilizing the slope and creating conditions for the surrounding landscape to function as intended. On unretained slopes, rainfall moves soil downhill, and after repeated rain cycles or freeze-thaw events, erosion becomes visible through rutted ground, exposed root systems, and depleted topsoil.
"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."
Retaining walls that lack adequate drainage introduce serious structural vulnerabilities. Water accumulates hydrostatic pressure behind the wall face, which can cause displacement or complete structural failure over time. The drainage system installed behind and beneath the wall units is as important as the visible hardscape material itself. Thorough planning ensures that each retaining wall layout incorporates the necessary drainage components from the start, including specialized base materials, clean drainage aggregate positioned behind the wall blocks, and a precise grading plan designed to direct water away from both the wall structure and the home's foundation.
Landscape retaining walls produce flat, stable ground, a structural outcome that an open slope cannot provide. That level surface makes a patio installation viable, gives custom planting beds a stable foundation, and establishes defined tiers across a property that can each serve a distinct purpose. In Central PA, where properties frequently feature pronounced natural elevation changes, retaining wall installation is often the foundational project that makes subsequent outdoor renovations possible. The design team approaches these structures as part of a connected outdoor environment rather than an isolated solution, ensuring the completed hardscape integrates cleanly with custom patios, paver steps, and softscape layouts.
