BDI Corr-A-Guard^®

BDI CORR-A-GUARD®, or gravel-less systems, were designed in the 1980’s to replace gravel leach beds. Available in 6”, 8”, and 10” diameters, these alternative systems enable the contractor/installer to replace costly gravel with filter wrapped corrugated tubing where soil conditions are favorable. BDI CORR-A-GUARD® features BDI’s patented molded-on coupling.

Product Highlights

• BDI CORR-A-GUARD® is a septic system which utilizes filter-wrapped pipe in place of gravel. The advantage of using BDI CORR-A-GUARD® is evident in areas where gravel is scarce and expensive. In addition, gravel-less systems generally require less excavating than traditional systems. This equates to less costs for the homeowner and contractor.
• Two holes, each 3/8” to 1/2” in diameter, are drilled in the valleys of alternating corrugations, 60° from either side of the bottom of the pipe. In addition, BDI CORR-A-GUARD® is covered with an approved spun bond geo-textile fabric. This product is stored in a heavy duty polyethylene bag or sleeve for protection during storage and shipping. (Hole requirements may vary from area to area and 4-hole systems are available.) Contractors should check with their local health department to determine requirements in their area.
• BDI CORR-A-GUARD® acts as a conveyance and storage system for the septic tank effluent and as a secondary treatment process to the effluent. The large diameter tubing provides better oxygen transfer capabilities due to the additional storage capacity and increased retention time.
• The pipe creates a settling basin for the organic solids carryover from the septic tank. The settled soils are then further stabilized by bacterial action, producing a quality effluent from the gravel-less tubing and reducing the organic load on the soil.

Features & Benefits

• Reduced labor and installation costs. Gravel-less systems generally require less excavating than traditional systems.
• BDI CORR-A-GUARD® 6”, 8”, and 10” is lightweight and easy to handle. The pipe is manufactured in 20’ sections and has a molded-on coupling for faster installation.
• Larger storage capacity for effluent; thus, improved distribution of wastewater in the trench.
• Increased retention of solids in the pipe, which enhances the main aerobic treatment in the septic tank.
