Marco Island is a boating community and has lots of canals... There are three types of seawalls on these canals: Original Deltona, T-Pile and Replacement Wall.
- Original Walls Designed by Deltona - these walls are over 30 years old and are normally 10'-12' in depth and 5'8' width and 4"-5" thick.
- T-Pile are 20'-22' poured concrete pilings;panels are normally 10-12' depth 5'-8' wide and 4"-5" thick
- Replacement Wall are generally thicker and better made, 14'long 6"thick, 5'wide and 5' into the berm.
Some Terminology you might want to be familiar with:
- Seawall Cap - Ties the panels together at the top -- there are two types Non-Structural and structural.
- Tie Backs - Threaded steel rods that goes from the seawall to a poured concrete anchor approximately 15' into the yard and located every 10'.
- Weep Holes - 1"-2" diameter hole to allow water to escape through the wall
- French Drain - a 2'x2' trench dug behind the seawall filled with 3/4" stone.
- Berm (ground) - support the toe of the seawall and prevents rotting from the bottom
