Eliminate Infiltration & Leaks

Water infiltrating from the environment into a manhole puts an additional strain on sewage capacity.

By sealing riser joints and cracks, we eliminate this issue.

We inject riser joints between pre-cast and cast-in-place manhole structures, and repair cracks to

eliminate leaking.

Application Benefits
