NMPA, Mangalore — berth pavement repair & re-laying
What we found
Paver pavements rarely fail all at once. They sink in patches. Water finds the low spot, sits there after every rain, softens what is underneath, and the patch gets a little deeper each season. By the time we were called to Berth No. 5, 6 and 7, there were areas holding standing water across yards and roadways, and broken sections getting worse under daily port traffic.
The blocks themselves were rarely the root cause. It is almost always what lies below them: the sub-base, the drainage, or how the pavement was laid in the first place.
How we repaired it
A repair that only lifts and relays the blocks on the same weak base will sink again. So each affected area was opened up, the sub-base rectified and compacted, and the pavement re-laid to line and level. Then jointing sand was worked into every joint before the area went back into use.
Wherever possible the existing blocks were re-used, which is one of the quiet advantages of a paver pavement: when the ground below needs attention, you can lift the surface and put it back.
Why this matters to port owners
Many owners live with sunken, waterlogged paver areas for years because they assume the only fix is a full replacement. It usually is not. Repair and re-laying as per IRC:SP:63 can bring a pavement back to level, including pavements originally laid by someone else.
