Reduce manhole building time by 2/3 with Ladtech adjusting rings!
Why spend hours building manhole chimneys with concrete rings when the Ladtech System allows you to complete chimneys in 1/3 the time? Ladtech's patented rings weigh a fraction of concrete because they're made of high-density polyethylene. Yet Ladtech rings meet AASHTO's HS-25 axle-loading spec, are impervious to the H2S corrosion that destroys concrete, and vacuum test every time when properly installed. Furthermore, Ladtech rings are made of recycled material, so you'll be doing yourself and the environment a favor.
