Experienced Engineering
Our team of experienced Professional Engineers is available to provide technical support on your Retaining Wall Projects. From preliminary feasibility studies to comprehensive, Engineer-Sealed (in some regions) Engineering Drawings, complete with quantity take-offs, full calculations and details.
Risi Stone’s decades of experience in the Design, Construction, and long-term performance of Segmental Retaining Walls makes our Engineering Team uniquely qualified to handle the most complicated and technical applications you may have. With the longest track record of proven installations in the industry, you can trust that your Project will look good and perform for many decades to come.
Our Block Design Simplicity Guarantees Performance
Accurate SRW Design assumes a number of important factors such as the Block Unit Weight, Shear Strength, Block/Grid Connection Strength, and Wall Alignment. With our engineered walls, all of these elements have been designed and built right into the Block. Designers can rest assured the structural properties are guaranteed to be exactly as they have assumed in their designs. There is no need to fill the block core with gravel and compact to guarantee the unit weight, or ensure connectors and pins are correctly installed for proper shear strength, alignment and grid connection. Our solid block is installed “as-is”. It’s that simple.
Design Services
Segmental Retaining Walls are considered “Designated Structures” by most National Building Codes, and therefore are required to be Designed by a Professional Engineer for heights exceeding 1.0m. Furthermore, a Retaining Wall System will only perform as well as the Design it has been constructed according to, and the devil is definitely in the details. Choice of geogrid reinforcements, drainage materials, material design parameters, various loading conditions, and the appropriate Risi Stone SRW product are all critical aspects of properly aligning the Design for the specific application.
Applying industry standard Best-Practices and Design Methodologies from organizations such as the National Concrete Masonry Association (NCMA – ncma.org), American Association of State and Highway Transportation Officials (AASHTO – transportation.org), Canadian Foundation Engineering Manual (cgs.ca), American Railway Engineering and Maintenance-of-Way Associations (AREMA – arema.org), US and Canadian Bridge Design Codes, and others, Risi Stone’s Engineering Team will help you navigate through the sometimes complex process of Design and Approvals for your next Project.
