Retaining walls built by Van Zeeland use proper drainage, base preparation, and frost-resistant materials specifically to withstand Northeast Wisconsin's freeze-thaw cycles. Without correct drainage, water trapped behind a wall freezes, expands, and shifts or cracks the structure over time, which is why base depth and backfill material matter as much as the visible stone or block. Crews grade and compact the base before any wall goes up to limit long-term movement. A properly built retaining wall holds its structure through many Wisconsin winters with minimal upkeep.

Seating walls serve a different purpose than retaining walls, adding built-in seating around a patio or fire feature rather than holding back a slope. The two are often combined on properties with grade changes, where a retaining wall manages elevation and a seating wall extends the usable space around it. Materials and finishes typically match the surrounding patio or hardscape for a cohesive design. A consultation determines whether a property's layout calls for one, both, or neither.

Retaining walls and plant selections typically get designed together, since the wall creates the structure and grade changes that plantings then fill in and soften. Van Zeeland's design team selects plant material based on the sun exposure, soil conditions, and drainage that each retaining wall creates, drawing from the nursery's inventory of trees, shrubs, and perennials suited to Wisconsin's climate. This coordinated approach avoids the common problem of a wall going in without a plan for what surrounds it. Combining structural and planting design in one process is a core part of larger landscape projects.
