Seawalls, which are massive structures, are designed to withstand the full force and impact of storm surge and waves. They also serve as a barrier between land and water along the shoreline.
Seawalls are only effective in preventing erosion along the coastline they are built on. This means that erosion elsewhere can still occur and could eventually cause property damage.
Polyurethane Injection
There are many ways to repair erosion behind your seawall. However, polyurethane injection is the most cost-effective and efficient. This method involves injecting a high-density expanding urethane resin into cracks and joints to fill them with a sealant that expands in the presence of moisture.
Water flows in and out of your seawall with every tide or wave, carrying soil with it as it passes through the gap. Over time, gaps can become wider and deeper. This creates an unsafe void that allows soil to be carried away with the water. This can lead to a whole host of problems such as sinkholes, cracked sidewalks and even compromised foundations of neighboring seawall structures.
Our team will repair your seawall using a high-density, expanding injected urethane urethane resin like URETEK486 Star. This resin is non-toxic and environmentally friendly. This resin can withstand all types of weather conditions. It also resists chemical agents making it the best choice for seawall repair.
This type of repair also has the advantage of being quick and easy. It will return your property to its normal use in hours. This is a much quicker option than grouting with concrete, which can take several days or even weeks. Additionally, it is more cost-effective as less material is needed for the repairs.
Epoxy is a strong, plastic-like substance which forms a hard bond when it’s cured. It can be used as a glue to repair cracks and joints. It is versatile and economical and can be used to strengthen weak seams and re-bar as well as concrete masonry.
Aside from its flexibility, it can also be used to fill voids and a wide range of other issues such as stabilizing and strengthening weak soils. The best thing about epoxy is its tensile strengths. This ability to stretch and flex can help the repair hold up over time, especially in wider cracks or joints.
Polyurethane foam is a great choice for fixing cracks or joints. It is flexible enough to withstand pressure changes and minor settlements. It requires less resin than epoxy and can also be injected in large cracks and loose soil conditions.
Jet Filters
Whether you live by the ocean or on a lake or river, seawalls protect property from erosion. They prevent the full force of waves from crashing into the shoreline and also redirect wave energy in one of two directions.
If you are looking for a solution to fix the erosion behind your seawall, consider using Jet Filters. These weephole filtration systems are made out of geocomposite and can be permanently attached to your seawall to reduce hydrostatic tension and stop soil loss through the weep holes.
JET Filter System offers a wide variety of products for retaining walls, seawalls and bridge infrastructure. These maintenance-friendly, weep hole filters can be used to prolong the life of your structure.
A retaining wall that does not have proper drainage can experience excessive hydrostatic tension, which can cause it to become unstable. This pressure can cause a number of problems, including bulking and toe kick-out, as well as sink holes.
These problems are especially dangerous if your property sits in an area known as an overwash, which is a location where the water from a storm exceeds its elevation and flows onshore. This can create serious environmental hazards, and can also cause damage to nearby land and structures.
In addition, if you have a leaking drain or see signs of sinking ground on the land side of your seawall, it is time to consider replacing it with a more efficient drain. Hire a professional to inspect and repair any problems with your drain.
Installing a French drain is another way of preventing erosion behind a seawall. This trench is usually 2’x2′ and is lined with filter fabric or sheathing.
Then, crushed stone is poured into the trench to fill it and form a foundation for the retaining wall. This will ensure that your retaining walls last longer by keeping them well-drained and preventing any growth of weeds or other plant life.
Cloth for Landscaping
There are many ways to repair erosion behind a seawall. One method is to install landscape fabric. This weed control product works well in areas with many plants, such lawns or flower beds.
Using landscaping fabric can help you prevent weeds from growing in your yard or garden, and it also protects the soil from water damage. It’s an excellent alternative to chemical herbicides and very inexpensive.
To prevent weeds from growing, you need to choose the right kind of landscape fabric for your project. There are many types of landscape fabrics, including non-woven and woven. Each type has its pros and cons.
Most commonly, woven landscaping fabric is made from polypropylene and linen fibers. It is semi-permeable and allows water and nutrients through to the ground. However, it also prevents weeds growing up towards the sun. This is the best option for controlling weeds around trees and shrubs, or in flower beds that aren’t regularly tended to.
Cost: Prices for woven landscape fabric vary depending on the size of each roll. $35 for a low-end roll of 3 feet by 100 feet, while a 10-foot-by-300-foot roll will cost $280.
Non-woven landscape fabric can also be an option. It is made from layers of bonded polypropylene fibers that are durable. This version of landscaping fabric is less permeable than woven fabrics and prevents weeds from sprouting in places where stones are installed.
If you decide to use non-woven landscape fabric, be sure to purchase a high-quality version that has a long lifespan. Otherwise, you might have to replace your fabric more often than you need.
Once you have selected the right type and size of landscaping fabric, you need to prepare the soil for installation. You will need to amend the soil with fertilizer and compost. This will improve the soil’s condition and make it more suitable to be planted.
Once you have the soil ready, start rolling out the landscape fabric. You can do this yourself, but it’s also helpful to have someone else do the work for you. You’ll be able to ensure that your fabric is correctly positioned and aligned in your project space. Secure the fabric with garden staples once you are done.
Rebar Repair
Rebar can often be replaced to fix erosion behind a seawall. This is an economical alternative to replacing the entire structure. It also prevents further damage from occurring and protects property.
This method of shoreline protection can be overlooked, but it can be very effective. It allows for water to pass through the seawall without movement and can reduce hydrostatic pressure. This is especially useful in areas where heavy precipitation is frequent.
Rebar repair involves the use of a high quality concrete mix that has been bonded using a suitable bonding agent. This is often done using a concrete screed or cement mortar. Concrete must be prepared to resist corrosion and be durable. It should also be treated to repel water and UV radiation.
Once the rebar has been replaced, it is important to address any remaining cracks or damage. These can be caused due to rust, spalling, deterioration or rebar delamination. These deterioration issues can cause water to seep through or underneath the wall, causing further erosion problems and possibly even compromising safety.
When dealing with rebar corrosion, it is vital to address the issue quickly and safely. The damage can be costly and time-consuming to fix.
The presence of rust-colored cracks in the bar is a sign that it has been damaged by salt water. These cracks can lead to more rebar corrosion and eventually the failure of the wall.
A void behind the seawall is another common problem that can cause rebar corrosion. These voids can form when the ground behind the wall settles or the soil surrounding it becomes loose or mushy.
These voids can then be filled with a polyurethane inject resin, which is designed to stabilize the soil, fill in the voids and bond with concrete. This material is often referred to as the “next generation” approach and offers multiple benefits.
In addition to the multiple benefits that polyurethane soil permeation and stabilization resin offers, this product is a much safer and more environmentally-friendly solution to the issue of erosion. This method will allow you to extend the life expectancy of your seawall, ensuring it remains intact and safe for many years to come.
