A system for replenishing embedded foundation preservation wraps with preservative comprises an embedded foundation, a preservation wrap, and injection apparatus configured to be inserted between the wrap and the foundation. The injection apparatus includes a profiled backing plate and a semicylindrical tube portion defining a lumen therebetween, with a preservative inlet and a plurality of outlet nozzles along a distal bayonet fronting portion. A syringe with a reciprocating plunger operates within the lumen to enable controlled delivery of preservative and purging of residual preservative after use. The plunger may be locked in retracted, inserted, or blocking positions to manage flow and prevent leakage.
