Homeowners across Central Pennsylvania are increasingly turning to retaining wall installation to combat the structural challenges posed by the region's freeze-thaw cycles, according to A Plus Landscaping, a family-owned design-build company based in Reinholds. The company, which has been constructing retaining walls since 2006, notes that sloped terrain common in Lancaster, Harrisburg, Hershey, and nearby communities often leaves backyards underused and vulnerable to erosion.
The primary driver of demand, says Marcus Waldner, Founder of A Plus Landscaping, is the severe freeze-thaw cycles that put immense physical pressure on unmanaged soil. "Many homeowners treat a slope as a permanent limitation to their property, but a properly engineered retaining wall completely changes how a yard functions," Waldner said. "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."
Without retaining walls, rainfall and repeated freeze-thaw events move soil downhill, leading to rutted ground, exposed root systems, and depleted topsoil. A properly constructed wall holds soil in place and redistributes the weight of the slope, keeping the soil profile stable across changing seasons. For Central PA properties, where frost depth and precipitation place consistent pressure on unmanaged grades, this structural function is a practical necessity.
Drainage management is a critical component. Retaining walls that lack adequate drainage can accumulate hydrostatic pressure behind the wall face, leading to displacement or complete structural failure over time. A Plus Landscaping ensures each wall layout incorporates specialized base materials, clean drainage aggregate behind the wall blocks, and a precise grading plan to direct water away from both the wall and the home's foundation. "The drainage system installed behind and beneath the wall units is as important as the visible hardscape material itself," Waldner emphasized.
Beyond erosion control, retaining walls create flat, stable ground that makes patio installation viable, gives custom planting beds a stable foundation, and establishes defined tiers across a property. In Central PA, where properties frequently feature pronounced natural elevation changes, retaining wall installation is often the foundational project that enables subsequent outdoor renovations. The design team approaches these structures as part of a connected outdoor environment, ensuring integration with custom patios, paver steps, and softscape layouts.
The implications for homeowners are significant: a properly engineered retaining wall can unlock usable outdoor space that would otherwise remain inaccessible due to slope limitations. For the industry, the growing demand underscores the importance of integrating drainage systems into hardscape projects to ensure long-term durability in regions with freeze-thaw cycles. A Plus Landscaping serves homeowners across Central Pennsylvania, including Lancaster, Harrisburg, Hershey, Mechanicsburg, Middletown, and Reading.
