Building retaining walls is a serious business and any potential customer needs to be very thorough when they choose a contractor for this job.
There are so many stories of inexperienced and rogue operators who do not understand the hydrostatic forces that act on retaining walls and thus build them incorrectly leading to failure and huge repair costs. The cheapest option is to do the job correctly, which may mean using an engineer depending on the wall height. The use of steel reinforcing and knowing how to place it correctly is integral in retaining walls. Steel provides the tensile strength required.
Waterproofing is often overlooked but it is absolutely vital in ensuring the ongoing performance of the wall. Using the right blocks to ensure a good flow of concrete inside the wall is another very important factor. Drainage aggregate material is critical in ensuring all water gets to the footing and is carried away in drainage pipes.
At Blueprint we know that omitting any step in building a retaining wall voids the whole process and will not achieve a high performing and long lasting outcome.
