Hi there! Hope I'm posting in the right spot. Looking to build a seawall on a canal front lot, and was just given a quote that seems a little (a lot) high considering I used to build bulkhead ing and piers in the US. Does everyone just build with concrete? Is that the cheapest method? and does anyone have a rough Idea of cost per linear foot? Thanks. Again, if I'm not posting in the right spot please direct me to the spot for people that would like get a better feel for actual construction costs there.
