Client Context

GSK is a worldwide biopharmaceutical manufacturer with two plants in Rockville, MD. The facility uses a vinyl ester coated fiber drainage system for its process and bio wastewater.
One building was being retrofitted to produce an important cancer drug. The above-ground piping had been replaced and 90% of the equipment was in place three weeks before startup when someone asked whether the under-slab piping had ever been inspected. It had not, and the inspection showed much of it cracked and at risk of failing once the plant came online.

Strategic Approach
- 01
Survey the next day
Dynamic Drain rearranged its schedule and had a pipe survey crew on site the next day; the system was a good candidate for lining.
- 02
Source the right resin
The piping would run above the temperature limit of typical drain-lining epoxies, so a special-order high-temperature epoxy was sourced, on the last truck out of Florida ahead of a hurricane.
- 03
Line around the clock
Two crews worked around the clock, seven days a week, and lined all of the piping in under two weeks.
- 04
Keep inspecting
GSK has contracted Dynamic Drain every year since to inspect, and where needed line, the under-slab piping in both Rockville buildings.

- 01Evaluation studyThe system is mapped, inspected by camera, and every section is condition-graded.
- 02Prioritized findingsGrades are weighted by system risk and turned into a plan, most critical sections first.
- 03RehabilitationTrenchless CIPP lining of the sections that matter most, without full pipe replacement. Access requirements are confirmed during the evaluation.
