Sheet Piling

The JET Filter System's Maintainable Weep Hole Filters are ideal for dewatering seawalls and retaining walls composed of sheet piling.

First, The JET Filter’s Maintainable Weep Hole Filters offer a valuable solution to the difficulties of maintaining retaining walls. This flush-mount, wick geo composite drainage system is designed to be installed on the front side of both seawalls and retaining walls, to prevent soil and backfill material from escaping through the weep holes in sheet pile walls. Additionally, it is simple to unclog as needed, thereby eliminating stress on the panels. Furthermore, the filter is highly versatile and can be used with all types of sheet pile retaining walls, such as vinyl, z-type steel, FRP composite, and aluminum. 

Second, like any sheet piling design, it is crucial to be aware of the impact of hydrostatic water pressure, as all structures will gradually experience an increase in this pressure. Furthermore, without proper drainage in place, the retaining walls may encounter numerous problems, such as, buckling, toe kick out, sinkholes, and other forms of failure. Moreover, these failures can be result in significant expenses. Regardless of the type of wall you are dealing with, it is important to take the necessary steps to prevent drainage from becoming an issue. 



In conclusion, the JET Filter’s Maintainable Weep Hole Filters provide a reliable and cost-effective solution for maintaining various types of retaining walls. As a result, this versatile system can be used with various types of sheet pile walls including the four categories you see below. In short, it helps to prevent soil and backfill material from escaping through the weep holes. Furthermore it eliminates stress on the panels and is easy to unclog as needed. It’s important to be aware of the  threat of hydrostatic water pressure increasing. It is crucial to have proper drainage in place. By taking the necessary steps to protect your investment with JET Filter, you can avoid costly failures in the future!

Sheet Piling Applications

Often used for building structures such as seawalls, bulkheads, and retaining walls, steel sheet piles are strong and equally important for projects where the wall is exposed. The pieces lock together and are usually easy to put in place even in tough conditions. To make the steel last a long time, it’s important to keep it coated and well taken care of.

Vinyl sheet piles are a cost effective product that can last for over 50 years. They come in different colors. In fact, these walls are usually not very tall because they aren’t as strong as some other options. To make them strong enough for marine structures, they often need extra support and drainage systems as a result.

Composite (FRP) sheet pile seawalls protect against erosion. In fact they are made from a strong material made of fibers and plastic. As a result it won’t rot, fall apart, rust or peel. Therefore this type of seawall is especially good for the environment.

Aluminum sheet pile provides good corrosion resistance, but given its lighter strength characteristics, it is in fact best for walls with minimal exposed wall height. There is corrosion potential of dissimilar metal hardware, as a result, do not use in waters with low Ph. and in fact, you should always use light, permeable backfill material.
