The trouble with ponding on roads can be seen often during rainy season. Many times it is a result of heavy trucks causing the road to sink.
The solution to sunken roads and ponding is PU injection which can lift-relevel the road and drain the water.
Steps to fix ponding
1. Staff conduct an initial investigation of the site
2. Drill a 16-mm hole through the concrete surface
3. Inject PU to fill the voids and lift the surface
4. Plug the drill hole with quick drying cement to prevent water seepage
