What happens here

After drilling, insert a 'zert' (a specialized injection port) into each hole. The zert is designed with a check valve to prevent the polyurethane foam from flowing back into the injection gun, ensuring a clean and efficient process. Attach the HMI Elite 1 injection gun to the installed zert. This gun is equipped with an air purge system, which continuously drives air through the hole during and after injection to keep it clear and allow for further material injection without redrilling. This system enables the operator to inject small amounts of foam, wait for it to set, observe slab movement, and then re-inject if needed.

Goal: Set up the injection port and gun for controlled polyurethane delivery.

Tools and materials

  • HMI Elite 1 Injection Gun HMI — To inject the polyurethane foam into the concrete slab
  • Zert — To create a sealed entry point for foam injection and prevent backflow

What they say

Hide

deck and patio or walkway or somebody's driveway okay tip is put insert inside the hole desert is nothing more than in an injection port it's got a check valve in it that prevents ascetical to follow urethane to come back into his gun he's now attached a patented HMI elite one flood to the dirt he has created therefore an air purge system is that important it's critical air purge system gains that gun is perpetually driving air through that hole as he is injecting and after he injects an Iver food material sets up that leads a small worm hole that perpetually in it so he can keep injecting more material without the hole that allows him to feather in a little bit of polyurethane wait ten to fifteen seconds let it set up see the movement and keep injecting now this is the world of concrete it's not the real world this is the one whole demo gif is objecting in one hole if it was the real world he'd probably have three or four starts on that clap and because that hole always remains open he can keep
