Property Owners

What is the best seawall or retaining wall material for your project? 

It really depends on your project and requirements, including size, loads, job site access, soil conditions, wall exposure height, and more.  As a property owner, whether you're a homeowner, commercial owner or developer, or government entity, we all work under budget constraints.  However, you want the best for your money.  And, there is a difficult cost-value decision to be made. 

Your land, property, home or business, and upland structures are all protected by one very important structure - the seawall or retaining wall.  You need to make sure it is built right and the first time.  You don't want to keep spending money fixing or repairing a wall. 

When it comes to deciding on your seawall material, engineer and contractor installer, make sure to ask a lot of questions.  Seawalls and retaining walls are expensive and you want to do it right.  There are many choices in materials and we'll look at the more popular choices.  Read more information about material choices based on exposure height and the associated cost.
