Gurgaon: The underpass on
near Sector 102 will remain closed during the next week as National Highways Authority of India (NHAI) undertakes urgent repairs based on recommendations from Central Building Research Institute (CBRI).

One carriageway of the underpass — from Sector 9 towards Sector 102 — was shut for commuters on Thursday evening and will remain closed till May 25. The opposite carriageway — from Sector 102 towards Sector 9 — will then be closed from May 25 to May 29. The phased closure is intended to minimise disruption to traffic.
The underpass was opened to traffic in June last year. Residents have been complaining about leakage issues within less than a year of its opening, demanding a permanent fix.
The closure aims to resolve prevailing water seepage caused by damage to movement joints, though no structural distress was reported, an NHAI official said on Friday. The official said, "It is completely safe."
According to a site assessment conducted earlier this month by the team of CBRI officials, along with NHAI and L&T officials, water ingress is occurring through the movement joints due to possible membrane damage and a high-water table in the area.
The team said the issue is limited to leakage and does not compromise the underpass's structural safety.
"But because of the high water table in the area, CBRI suggested targeted repair measures to arrest the seepage. Polyurethane grouting, which is quick-setting and reacts with water, has been recommended as the most effective solution. The repair work is being carried out urgently and in line with Indian Road Congress and MoRTH guidelines, with strict adherence to curing protocols and on-site safety," the team said.

While other grouting options — such as cementitious, chemical and microfine — were considered, polyurethane was preferred due to the nature of the leakage. The procedure involves drilling near the affected joints, cleaning the area, injecting grout and following strict curing standards.
Sector 102–102A underpass already underwent repairs using grouting last month by the expressway's maintenance agency. NHAI subsequently brought in CBRI for a detailed structural review, which led to the current round of repairs.
Built at a cost of Rs 24 crore, the 585-metre-long, four-lane structure lies beneath the Dwarka Expressway and was designed to ease congestion and improve connectivity across the rapidly growing residential sectors. It provides direct access to areas including sectors 102, 102A, with sectors 101, 104, 9, 9A, 9B, 10, 10A, 37, and 37C and further to NH8.
Construction of the underpass began in 2019 but faced delays due to land acquisition hurdles. Work came to a halt in Jan 2022 and resumed only after the Haryana Shahari Vikas Pradhikaran resolved land issues in Sept 2023.
