Joint testing is typically not necessary for drainage applications. Largerdiameters, which are predominately used in corrugated HDPE pipe,make pipe joint testing dangerous when testing with air. Therefore, ifit is determined that watertight joint testing is required, the pipe must betested in accordance with ASTM F2487: “Standard Practice for Infiltrationand Exfiltration Acceptance Testing of Installed Corrugated High DensityPolyethylene Pipelines.”Warning: Testing corrugated HDPE with air poses a hazard as a result ofthe stored energy associated with compressed air. Air testing may result inpipe failure and/or injury to property and/or persons.6.4 Repair Methods for PipeRepair methods largely depend on the performance expectations of the pipejoints and size of the damaged area of the pipe wall. Repair methods aregenerally divided into two categories (1) soil tight and (2) watertight, whichare described below.6.4.1 Soil Tight Repair MethodsSoil Tight Repair Option A – Split Band CouplerThis method can successfully repair 4 inches to 60 inches in diameter andinvolves wrapping a split ban coupler around the pipe covering the damagedsection. Limitations for this repair method include:• Non-traffic applications (see Option B for traffic applications).• Hole or damaged section of pipe less than or equal to 10 percent of thepipe diameter.The following steps describe the repair process:• Place split ban coupler so that it is centered over the damaged area.64 EAGLE CORR PE INSTALLATION GUIDE
