Sewage pipe cleaning and CCTV inspection of 6.8km pipeline, pipes 150mm to 1800mm diameter.
Client: NWC — National Water Company · Location: Saudi Arabia ·
Robotic crawler cameras map every meter of the line — cracks, joints, corrosion and blockages located to the centimeter.
The host pipe is jet-cleaned and prepared, restoring the full internal diameter before lining begins.
A resin-saturated liner is inverted or winched through the existing pipe — through manholes, no trenches.
The liner is cured into a structural pipe-within-a-pipe, CCTV-verified and certified with a 10-year warranty.
