Failures Of Retaining Walls

April 15, 2019 • Lucille McAlpin

In modern times construction of retaining walls are increasing with speed. They have to be, as there many reasons why today’s artefacts need retaining walls Sunshine Coast. It depends on the area and the soil condition that what type of retaining wall should be installed in a particular area whether it should be sleeper retaining wall, gravity wall or any other retaining wall. Building a retaining wall is like walking on thin ice. Because we are in competition with Mother Nature herself so, Of course, we will face challenges and problems during the construction.

First of all building, a cheap retaining wall is nothing but playing with your own self. This wall is something that has to be stout and strong enough to do all the jobs it is building for. There are many debatable reasons why failure occurs while building and after the completion of the construction. A poor drainage system is the most recorded reason why a retaining wall fails. This is so important because if the water does not find its way out, the water pressure will keep building up and eventually due to the pressure of water the wall will break down. The other factor is the poor judgment of the site. For example, the civil engineer decides whether a retaining wall is required in the particular project or not then the geo-engineer will tell that what type of retaining wall is required by investigating the area. If the observation and analysis were not accurate and the wall was built completely opposite of the real conditions then definitely the wall will be a big failure. This also includes the miscommunication and blunders of the team members.

The other reason is that the slip-ups and omission in the design. The inaccuracy in calculations in the specific area for the wall will lead to many problems and failures in the future. The inappropriate footing in the design will surely become the reason for the wall to fall down. There are a considerable amount of other mistakes that a designer can make that leads to the failure of the construction of a retaining wall. Putting extra weight on the wall makes an unstable wall. The weight has to be favorable in a satisfactory design. The placement of the retaining wall blocks contributes to the quality of the wall. If the gaps are left behind in the wall the water and the soil will go through these unfilled areas and will weaken the retaining wall. Small sized rocks must be poured or set between the natural soil and the retaining wall because due to their shape and size water finds its way to the earth. Water pressure is to build up between the wall and the natural soil if it does not find its way to get out.

The angle of the slope in the retaining wall also matters because, because of the perfection in the angled wall can adjust itself accordingly and will work against the gravity better. If the slope is incorrect the whole wall may breakdown. So, these are the few reasons why a retaining wall can fail. There is a number of other technicalities muddled in this issue.
