Depending on where you live, dealing with heavy rain and the threat of landslides or floods might be major factors when planning your home or business. According to FEMA, just one inch of flooding in your home or business can cost you $27,000 in repairs. Landslides have the potential to bury your building completely. Most use some kind of retaining wall for protection from landslides and flooding. Here are the top benefits of precast concrete retaining walls.
Precast concrete is not poured on-site like cast-in-place concrete. It is manufactured in a temperature-controlled facility by skilled technicians. Once all the components are complete, they are shipped to your project site to be assembled.
Assembly is relatively easy and doesn’t need skilled workers – although you might need a crane or forklift. The area is prepped and leveled, the support posts installed into the ground, and the wall panels are lifted over the support posts to slide into place. Concrete caps are placed over the support posts to cover the opening, and the wall is finished.
With cast-in-place concrete, each step has to happen one at a time. With precast concrete, you can cast multiple parts at once and do other steps, like prepping the ground, while the concrete is casting. Since everything is made indoors, there are no weather delays. Most times, your precast concrete retaining wall will be ready much quicker than other methods of construction.
Long-Lasting and Durable
Another considerable benefit of pouring the precast concrete retaining walls in a temperature-controlled facility is it is much easier to control the quality. Bad temperatures and weather can lower the strength of concrete during the curing process. In fact, concrete has an optimal curing temperature.
The concrete is typically also cast with steel reinforcement and strengthening mesh. Both of these options are relatively typical of all concrete walls – including cast-in-place – but sometimes mistakes during cast-in-place concrete pouring can leave voids or gaps that damage the effectiveness of the reinforcement.
Every part is thoroughly inspected before leaving the facility. If a wall panel is a cast that is less than optimal, that part is removed and replaced with a better one. This is another layer of protection to ensuring the precast concrete retaining wall is durable and will last. You don’t want to be worried about the strength of your retaining wall when a storm comes through.
One of the biggest budget killers when doing a cast-in-place concrete retaining wall is paying for the construction and removal of all concrete forms. Precast concrete molds can be reused over and over again – often up to 40 or 50 times. This helps cut the cost to make the wall, and that savings should be passed on to you.
Because the walls are so long-lasting and durable, thanks to the way they are made, maintenance costs are minimal when compared to other retaining walls. Usually, the wall will just need the occasional wash and inspection.
