Settlement Prevention

A major goal in any engineering project is ensuring stability over a lengthy design life. To achieve this, it is essential to account and plan for a number of variables that can arise over a structure’s life cycle.

One such variable is settlement – changes to the ground underneath a structure that can cause drastic issues down the line. As such, it is important to employ ground support efforts, including settlement prevention, in any project.

What is settlement?

Simply put, settlement is the displacement that occurs when the weight of a structure presses down on the ground underneath it. There are two primary sources of this displacement – weight from the structure and changes in the ground composition.

In a settlement analysis, two types of weight are generally accounted for. The dead load accounts for the weight of structural elements like walls, beams and floors, while the live load represents the weight from items and materials placed in the structure – the stocked items in a grocery store, for example, would constitute the live load.

In addition to live and dead loads, settlement can result from changes in the soil underneath a structure. This type of settlement is not always immediate; it can occur long after construction has been completed. It typically results from soil movement, compression or expansion – often exacerbated by the presence of layers of clay and sand or the introduction of groundwater over time. Ground support measures are essential in addressing this.

The importance of settlement prevention

While some settlement can be expected, uneven settlement can cause significant issues with structural integrity. This can leave visible and hidden indicators, such as a weakened foundation or cracks and distortions in the facade. If left unchecked, settlement could lead to a structure’s collapse.

For a famous example of settlement known the whole world over, one just needs to look at Italy, where the Leaning Tower of Pisa stands both as a warning against poor soil preparation and a monument to the success of diligent and innovative engineering solutions.

Of course, the Leaning Tower wouldn’t be nearly as famous as it is if it didn’t lean – few tourists want to take pictures where they’re propping up a straight structure. New projects, however, would be well-served by a proactive effort to mitigate settlement. Leaning buildings and other signs of settlement are likely to repel clients and investors.

As such, it is crucial that engineering projects be undertaken with the right materials and know-how that can prevent settlement and deliver high-quality results.

How can Bluey help with settlement prevention?

Any settlement mitigation plan must begin with understanding the conditions of a project site. Bluey’s engineering consultants can lend their experience and know-how in order to assess ground conditions and prepare effective measures to counteract the risk of settlement.

Bluey’s BluRez line of products can also play a role in settlement prevention. BluRez CSW, a water-reacting polyurethane resin, is particularly effective at preventing ground water movement – a common cause of settlement. BluRez CSW can also be used for underpinning foundations and consolidating loose rock formations.

BluRez CSW offers a number of distinct advantages that make it an asset in settlement prevention measures, including:

  • Practicality: It only needs to be mixed with BluRez CSW-X for activation, making it easy to use on site.
  • Value: High reaction expansion means that a little bit of CSW goes a long way.
  • Effectiveness: BluRez CSW easily penetrates into wet sand and dense soils – which can cause settlement – and give it more stability.

The right advice and materials go hand in hand to deliver the most effective settlement prevention plan. Reach out to Bluey today to learn more about how we can support your project needs.
