To some, it may seem impossible to meet the flatness required by the Americans with Disabilities Act’s (ADA’s) 2.1 percent maximum slope for random traffic floors, landings, walkways, sidewalks, curb ramps, entrances, exit ways, ramps, and intersections at walkways. However, predictable concrete flatness techniques are achievable, provided the design/construction team follows certain practices and engages in specific strategies.

Designing Plaza Hardscapes: Considerations from insulation and waterproofing to structural support

Untitled-1

Plaza construction typically incorporates various products from different manufacturers intended to provide the thermal resistance, water management, structural capacity, and wearing surface needed to meet a particular project’s requirements. This article discusses the importance of evaluating the strength and stiffness characteristics of a plaza system, particularly when heavy loading is anticipated. Designs that do not properly account for overall system strength and stiffness are vulnerable to damage, potentially resulting in cracking and displacement of the hardscape materials, reduction of drainage capacity, and reduced service life of the plaza.

The U.S. Environmental Protection Agency (EPA) estimates stormwater runoff is responsible for 70 percent of all water pollution in lakes, rivers, and creeks. When developers use conventional methods such as impervious surfaces, stormwater is often left uncontrolled. The emergence of low-impact development (LID) and effective stormwater Best Management Practices (BMPs) are changing designers’ perceptions of stormwater from a constraint into an opportunity for natural processes to return.
