Mark Slack, president of ICON Underground LLC, is working on the Lawrence-based company's first contract, worth about $400,000 from the city of Lawrence. The work starts with inserting a sleeve of special felt, above, into aging sewer pipes. The felt, soaked with resin, then is cured in place to seal off any cracks and improper connections into the pipe. The work extends the sewer's life without having to dig it up for replacement.
