Concrete Block Retaining Walls vs Segmental Retaining Walls

Retaining wall contractors are often called to the scene of a collapsed retaining wall blocks only to find the wall in question was made of concrete. The reason for the collapse is always evident. The nature of the request, the walls have been retained to cover the cost of behind them, where the land on which they are intended to be maintained.

When we study the concrete, the design itself tell us much about whyfail when he pointed out to the side. As with all devices, cables, they are the strongest when the load is brought down from top to wear when in their normal orientation installation. The way in which the concrete is most often used to build walls of buildings, most of the load is placed on top, pushing the land where a concrete foundation carries the load.

A simple test of the power blocks is possible by means of a standard framing hammerand hitting the sides of the block. With little effort, the walls crack and the block is no longer of any use.

Compared to a concrete block, segmental block retaining wall is solid concrete and high density. With the same dog before, you can easily put yourself before the bust of the block. You can break the corners and edges, but it takes a chisel and a hammer to cause real damage to the slide.

Anotherproblem with concrete blocks is their ability to absorb water. We are all aware of the expanding force of the water freezes, so we can understand that a retaining wall, one that is constantly in contact with the earth behind, it would be wet most of the time. This can not be said for the wall of a building that is protected from the rain outside and be open with the air inside.

When the temperature is below freezing for a sufficient period oftime to freeze the ground, it will also freeze water in support of your retaining wall blocks. while it may take several years depending on the number of freezes you every year at the end cracks begin to form, both the blocks and mortar used to hold them together.

Segmental retaining wall blocks are impermeable to water. They may be in a water bath for several years and will never absorb water deeper than one-eighth ofinches. The high density of concrete is too thick in the water to introduce the band. The freeze will not make more of a hot day in these blocks.

With the wide variety of materials used for the last 100 years the walls of thousands of reserve in all areas of the country that are not flat, it's no wonder that a system of retaining wall would then be able to withstand the test of time. For too long we have used independentmaterials were available with little thought for the future.
