Marine Walls by LOC-A-BLOC

The LOC-A-BLOC 600 Series and 1800 Series blocks are used for marine applications.  They are by far the strongest and most superior block systems around, specifically designed for use with marine situations.  Our marine walls are constructed with 40 mpa concrete for maximum strength and longevity in this environment.

Constructing a marine wall is the best guarantee against controlling erosion on both coastal locations and river banks, and of course the ever changing sea levels.  Another use is to construct levy banks for the control of flooding, rising water levels, basin, lakes and all other marine situations.
