Site conditions aren’t always predictable. Whether you’re installing a culvert wall on a residential driveway or designing stormwater management for a commercial property, you’ll want to use materials that provide the flexibility you’ll need for a variable environment. The End Wall Sectional from Hartman Products gives contractors, landscapers, and designers the flexibility to adapt Stay-in-Place drainage walls to a wide variety of site elevations and project needs.
What Is the End Wall Sectional?
Maybe it’s the ambiguity of the name, but the utility of this piece is often misunderstood. The end wall sectional is an individual panel designed to work with Hartman’s plastic SIP culvert wall system, working as an adjustable-height building block, allowing installers to increase the height of a wall where needed. These pieces can also be stacked one on top of another to create small retaining walls, closed off with an end cap once the final sectional is in place.
Unlike other endwall types, the Hartman Products system is effortlessly height-variable- and the sectional unit is at the heart of that. Installation is akin to building blocks, with units simply stacked on top (for more details on this, check out how to install the full plastic culvert wall).
Residential Applications: Driveways, Yards, and Retaining Walls
In residential settings, elevation changes are common. Driveways may slope sharply toward the road, or landscaping around culvert outlets may require taller headwalls to prevent soil erosion. The end wall sectional allows homeowners and contractors to easily add height to match these site conditions that would otherwise create a big headache.
Some common uses include raising the height of culvert walls on sloped driveways, building small decorative retaining walls around culvert outlets, and blending drainage features into the surrounding landscape. These units can also be used to adjust for deeper buried pipes by adding in more vertical support. With this product, homeowners can achieve a professional result without needing to pour concrete or hire specialized crews for non-standard culvert areas.
Commercial Applications: Site Drainage, Parking Lots, and Retaining Structures
Commercial and light industrial sites often feature varied terrain- parking lots with cut-and-fill construction, engineered slopes for stormwater control, and roadways that need consistent drainage performance. The sectional unit makes it easy to adapt culvert walls to these varied elevations without adding complexity, and thus time and resources, to the project.
Some projects we commonly see include matching culvert wall height to engineered slopes and swales, creating visually consistent retaining walls near public-facing areas, and accomodating different pipe depths across a large site, with Hartman SIP culvert walls having zero, one, or two sectionals depending on the needs per installation. When paired with sustainable site drainage strategies, the end wall sectional helps reduce reliance on poured concrete, saving time and budget while offering an eco-friendly solution.
Why Builders, Landscapers, and Engineers Prefer the Flexibility
Across both residential and commercial markets, the sectional unit has become a popular addition to the Hartman Products lineup because of its flexibility and ease of use. The sectional easily adapts to site-specific height requirements, allowing builders, landscapers, and engineers to accommodate varied elevations without redesigning the entire drainage system. Its modular design makes it stackable, which is ideal for creating small retaining structures when needed. Compared to poured concrete or gabion baskets, the system blends in much better with the surrounding landscape (case study here of the low-impact for developers). It also delivers significant savings to labor and time, as each installation can typically be completed in about an hour without the need for heavy equipment (case study of a housing complex wide installation).
