Backfill is an integral part of successful retaining walls Kelowna. Without proper backfill, your wall can lack structural integrity. So, what is the best material to use as backfill for your wall? In this article, we give you the low-down on everything you need to know about backfill. From why you need it, to types of materials, discover it all, below!
Backfill for Retaining Walls Kelowna: Why You Need it and Common Materials
Why Retaining Walls Need Backfill:
- Retaining walls need backfill for several reasons. For instance, pressure reduction. By utilizing backfill you help to distribute the pressure exerted by the retained soil, which minimizes the risk of your wall collapsing. Additionally, it helps mitigate lateral earth pressure, thus enhancing the overall strength of your structure.
- Another reason backfill is critical is for drainage. Any good retaining wall needs to be able to drain moisture so that water build-up does not occur.
- Finally, backfill ensures a compact support for the retaining wall which helps minimize settlement.
Common Backfill Materials & Their Purpose:
- Gravel: Often used in situations where drainage and compaction are required. This is because gravel is ideal for preventing water build-up and can easily be compacted.
- Crushed Stone: Similar to gravel, crushed stone offers good drainage and compaction properties. Moreover, it is highly resistant to settling and erosion.
- Sand: A material that is most usually used for walls with moderate height and well-drained soil. However, it is important to mention that sand must be compact to prevent settling.
- Soil: Much like sand, soil can be used from on-site if it has suitable properties (ie. not clayey or prone to retaining water) as long as it is well-compacted.
