High pressure CIPP to rectify DN600 GRP storm water pipe under At Takhassussi metro station.
Client: BACS — Riyadh Metro · 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.
