Soil Nailing
Combining Hydraway with soil nail walls is one of the most effective earth retention solutions on the market today.
How Do Soil Nails Work?
Any mound of earth or retaining wall without soil nailing or proper drainage is vulnerable to problems such as erosion and even catastrophic failure. When soil nails are used in combination with a Hydraway drainage system, retaining walls and other similar civil infrastructure can better perform their desired functions.
Soil nails are vertical rods—often constructed from stainless steel—that are drilled into the earth as a means of reinforcing sloped sections of earth. Soil nails can be installed to be either shallow or deep in the earth and are appropriate for use in open or confined environments with limited space, such as under bridges.
This technology has its roots in the middle of the 20th century when anchored bars were used to support retaining walls. Soil nails are permanent installations today but were used as temporary tools to support the safe excavation of earth in Canada and the United States. This was a cost-saving and time-saving technology that worked better than conventional tieback construction solutions.
Today, soil nail retaining wall construction can reach up to 75 feet tall. Soil nail walls are now considered the most effective solution for temporary and permanent support for building excavations.
Combining Hydrawayy With Soil Nails
When soil nails, also known as ground screws, are installed, the structural integrity of earthen structures is dramatically strengthened. However, these structures are still vulnerable to the erosive effects of water. An effective drainage solution can be installed alongside soil nail walls to mitigate these effects.
Soil nailing is installed in a grid-like pattern at varying depths along a slope. Along the line of soil nails, Hydraway can be installed to direct water to escape. Hydraway can boast a zero percent failure rate, meaning when it’s installed along with soil nails, effective earth retention solutions can be maintained on a temporary or permanent basis.
Hydraway is, in fact, easier to install than conventional perforated pipe drainage solutions. This is critical for all applications of drainage solutions, such as sports fields or residential foundations, but when earth retention is the goal, easy installation is paramount. Because earth retention and excavation are critical for safe construction, safe retaining walls, civil infrastructure, and even safe commercial or residential landscaping, it is important that the drainage solution not add difficulty to the process.
Soil nail wall systems are a perfect match for Hydraway because both present the best solution available today for construction projects. When the two solutions are combined, they are a powerful system that keeps people safe and helps ensure the success of earth retention projects.
Here are some of the benefits of Hydraway versus conventional perforated pipe drainage systems:
- Higher Inflow Rate: Hydraway allows water to enter the system and flow freely to its destination in a way that traditional perforated pipe systems simply can’t match.
- Clog Resistance: Hydraway’s needle-punctured fabric exterior is thermally bonded to the main flat drain structure to prevent dirt, silt, or sand from entering the system.
- Easy Installation: Hydraway comes in custom lengths up to 2,250 feet, and because it does not exhibit coil memory after being shipped, installation is speedier.
