There are a few different reasons why you might have sinking concrete blocks. It could be due to the weight of the blocks themselves, the ground underneath the blocks shifting, or water seeping into the ground and causing the soil to erode.

No matter the reason, you can take steps to prevent your concrete block from sinking. In this blog post, we’ll go over a few steps, so you can keep your concrete blocks in place.

The Weight of the Blocks

When it comes to choosing concrete blocks for your project, the weight matters greatly. Heavier blocks may seem like a better option at first, but if they aren’t rated for the load they need to bear, they risk sinking and causing damage. On the other hand, selecting blocks that are too light can also cause problems as they may not be able to support the weight placed on them.

Always check the load rating of the blocks before purchasing, if you’re unsure about what weight your project requires. Ignoring this significant step could lead to disaster down the road. On the other hand, using properly rated blocks will ensure a strong and stable foundation for whatever structure you’re building. Don’t skimp on quality—it’s worth it in the long run. It may be tempting to skimp on materials and pick the cheapest concrete blocks you can find, but this could have dire consequences.

The weight of the blocks is an essential factor in determining their stability and longevity. It’s important to properly assess your needs before purchasing and potentially invest in testing if necessary. Consulting with a professional can also provide valuable insight and ensure safe and successful construction. In the end, taking the time to select the right weight of the block can save you from costly repairs in the future.

So, before starting your project, make sure that you have selected appropriately heavy concrete blocks. Not only will it save you from potentially costly repairs down the line, but it will also help ensure the safety and stability of your finished structure.

Shifting Ground

When it comes to your home foundation, you want something that is going to be durable and long-lasting. That’s why concrete blocks are such a popular choice; they’re strong, and they can stand up to a lot of wear and tear. But even concrete blocks can sink over time if the ground underneath them isn’t properly compacted.

As time passes, the earth underneath the foundation can settle, causing the blocks to sink with it. Shifting ground can cause the blocks to settle, which can lead to cracks and other damage. Fortunately, some steps can be taken to help prevent this from happening.

Before laying down your foundation, make sure to compact the soil. This will create a sturdier base and reduce the likelihood of settling and sinking over time. It may seem like an extra step in the construction process, but it can save you from major headaches and repairs down the line.

Water Seepage

If you’re noticing water seepage in your home, it’s important to take action to prevent further damage.

Water seepage can cause several problems, from eroding the soil beneath your foundation to causing concrete blocks to sink. Good drainage is essential to prevent water seepage. Be sure to grade the soil around your foundation so that water drains away from it. Unfortunately, water seepage can lead to erosion of the soil, causing the blocks to sink even further into the ground and causing even more problems. If you’re concerned about water seepage in your home, consider contacting a foundation specialist for help.

Make sure gutters and downspouts are in place to redirect rainwater away from the foundation as well. Rain, melting snow, and sprinklers can all contribute to water seepage around the foundation of a concrete block building. As the water seeps into the ground, it can begin to sink, causing cracks in the foundation and potential structural damage. Fortunately, there are steps you can take to prevent this from happening.

  • Installing gutters and downspouts can redirect water from the roof to the ground and prevent it from seeping into your home.
  • It’s also a good idea to plant vegetation around your home’s exterior to help prevent water from pooling near the surface, where it can soak into the dirt below the foundation and cause erosion.
  • Excess moisture in the soil can also cause the bricks or mortar in your concrete walls to crack or deteriorate over time as well. By installing gutters around the exterior of your home, you can help prevent excess water from soaking into the soil near your home’s structure and minimise the risk of water damage to your walls.

These measures can help keep water from causing erosion underneath your concrete blocks, which would ultimately lead to sinking. Taking prevention steps now can save you from having to deal with costly repairs in the future.


If you have sinking concrete blocks, it could be due to the weight of the blocks, shifting ground, or water seepage.

To prevent your concrete blocks from sinking, select ones rated for the load they will be bearing. Compact the soil before you lay down your foundation, and grade the soil around your foundation so that water drains away from it. By taking these steps, you can help keep your concrete blocks in place.

If you’re having trouble keeping your concrete blocks in place, be sure to consult with a professional. They can help you select the right blocks for your project and provide tips for keeping them from sinking.
