water and road engineering

The New Berlin railway station is built on a water table smilar to that of Lae and the engineers have had to bolt the 1m thick concrete floor into rock about 30 metres down. My proposal for Lae road engineering is rock trenches about 1m down from the road surface, The trenches need only be half m. wide and 1m deep and placed at both edges and in the middle of the road. The rocks would be held in place by wire mesh on the sides of the trenches. Water looks for the weakest resistance and it would ooze itself out in the rock trenches instead of being compressed by the concrete which sooner or later will crack under the water pressure - which happens now with the Lae roads. Water ON the road is not the problem - it is the water UNDER the road which over time makes the road not a road. Problem solved. Applause, take a bow, throw money .
