Precast box culvert has long been recognized as a way to speed up the construction of DOT, civil, and commercial projects. Recently, this advantage has been enhanced with the introduction of the Complete Precast Box Culvert System by Permatile Concrete Products Company.
How is a box culvert constructed?
Permatile manufactures precast box culvert in single or monolithic multiple cell sections. With the advent of new technology, double and triple box culverts can now be manufactured in one monolithic unit with laying lengths up to eight feet, thereby eliminating the cost and time-intensive installation of multiple lines of single-cell boxes. Permatile’s precast box culverts may also be skewed in most cases to meet the project requirements.

The HY-SPAN Bridge SystemTM utilizes a three-sided, flat-decked, rectilinear precast concrete bridge unit placed segmentally onto a concrete foundation. The segmental units are connected together by means of mechanical lateral ties such as post-tensioning rods or strands and by a grouted keyway preformed into the foundation and at the mating surfaces between adjacent units. The HY-SPAN system offers clear span units from six feet to fifty feet coupled with vertical clearances from two feet to fourteen feet so that a wide range of opening configurations can be achieved. HY-SPAN units may be cast with a skew angle up to 45 degrees or in radial and transitional shapes. The foundation, wing walls and guardrail may also be precast or cast-in-place depending on site conditions.
A typical, totally precast installation may be made in less than one day!

Cable Concrete is the premier precast articulating concrete block mat system. It consists of pyramidal-shaped concrete blocks interwoven with stainless steel cable, underlaid with a durable geotextile fabric. These characteristics allow for unsurpassed flexibility and ease of installation. Add stainless steel aircraft cable running both lengthwise and widthwise, offering loops on all sides for clamping to adjacent mats, and a durable concrete erosion control system is created that can protect any size or shape area. Cable Concrete provides the Owner with a cost-effective solution that allows water permeability, vegetation, contour flexibility, subsoil confinement, and long term control of erosion.
CABLE CONCRETE DESIGN FEATURES
The plant manufactured in needed mat configuration and delivered to the job site for fast and economical installation.
4000 psi minimum concrete.
Air entrained concrete for durability and freeze-thaw fracture resistance.
Type 302 stainless steel cable.
Cables looped on all mat edges to provide for mat to mat connection and optional anchoring.
Geotextile fabric attached to the mat at the plant.
20% to 40% open area to provide water permeability and vegetational growth.
Pyramidal block shape allows for articulation ranging from 20′ to 60′, depending upon block size.
Complete engineering analysis, with flume testing, has been conducted by the Department of Civil and Environmental Engineering, University of Windsor, Ontario, Canada. Cable Concrete is manufactured to exacting specifications, which exceed both federal and state D.O.T. requirements.
Before Planting
After Planting
CABLE CONCRETE FACTS
Stability: Hydraulic conditions and flow velocities determine the block size and layout design needed to stabilize the erosive forces. The Cable Concrete mats, with the interwoven cable and mat to mat clamping, become one homogeneous control system. Cables are precast through each block, assuring both lateral and vertical stability.
Flexibility: The pyramidal shape of the blocks provides for large angular variability. This flexibility allows the system to adapt to abrupt changes in grade contours.
Permeability: The open area of the mats allows for sufficient transfer of water between the subgrade and the system surface. The attached geotextile fabric allows for the relief of hydrostatic pressure without permitting the migration of subgrade fines.
Vegetation: Native and exotic grasses, broadleaf plants, and shrubs will grow in the open area of the mat if desired. Its smooth surface allows for easy access by pedestrians and vehicular traffic and affords easy maintenance of vegetation. Plants’ root systems actually enhance the stability of the system over the years. Because the cables are precast into the system, blocks can be removed for larger plantings without compromising the integrity of the system.
Reusable: The cables of the mat allow for use as a temporary concrete erosion control material, for construction traffic or emergency situations. The mats can then be lifted for more permanent placement elsewhere or put into storage for the next job site.
INSTALLATION
The Cable Concrete erosion control system offers quick installation by the Contractor or Owner. Mats are delivered to the job site by either flatbed or boom truck. When possible, the 4 foot by 16-foot mats is delivered for placement by installer directly from truck to prepared ground, minimizing handling.
The mats are lifted and positioned with a lift bar supplied by the manufacturer. With the geotextile fabric already attached, the mats are normally placed in sequence from the downstream end of the job to the upstream end. This shingling of the fabric eliminates the potential for undermining of the completed system.
Anchoring of the completed system may be advisable, due to steep slopes or high water velocities. This anchoring is usually done at the upstream edges and in areas where excessive turbulence may occur. While all engineering data used to design a project is based on unanchored mats, anchoring offers an additional margin of safety and is often recommended.
Once placed, clamped, and anchored, the Cable Concrete erosion control system can receive a variety of surface treatments. Washed rock can be dropped between the blocks for a clean, unvegetated look. Black dirt can be spread between the blocks and the area seeded for a fully vegetated, easily mowed surface. Or it can be left unfinished, allowing sediment and natural growth to determine final appearance.

Utilizing HYSPAN™ precast concrete tunnels rigid frame sections with a unique joint design, the single-lane road under U.S. 460 was reconstructed into a two-lane road after the metal plate arch failed.
Permatile teams engineered, precast, and transported the 114 rigid frame sections to the project site for installation by the contractor. A second single-lane tunnel was built under the four-lane U.S. 460 simultaneously, to replace a failing metal plate arch.
The project started in mid-summer 1994. The concrete tunnels were completed in late August.
Local highways and a pedestrian walkway occupy the HY-SPAN SUPERBOXES. Both structures have 17-foot rises, average lengths of 134 feet, and respective spans of 30 feet and 24 feet.
WHY USE HY-SPAN SUPERBOXES?
There are some definite advantages to using HY-SPAN SUPERBOXES for this type of concrete tunnel project.
Advantages of the HY-SPAN SUPERBOXES include:
The speed of installation helps the project get completed faster.
The ability to spread the load of the structure over a substantial area.
The HY-SPAN SUPERBOXES allow low strength soil to be built on.
The Superbox design was chosen because of the questionable foundation conditions under the roadway and the superior bearing capability of the Superbox.
