3 Benefits of Using Driven Precast Piles on Difficult Soils

The type and quality of the soil on your site affects your choice of piling. If the soils on your build are more difficult to work on than the norm, then driven precast piles might be the best solution. Why?

1. You Don't Remove Any Soil

If you use some piling solutions, then you have to excavate the ground to create a hole to hold the pile. As well as giving you a lot of earth to dispose of, this type of piling doesn't always work well on problem soils.

For example, if you're working on contaminated ground, then you might not want to dig any of it out. The soil might not be a problem if it is left in place, so you don't want to excavate and then have to find a safe way to deal with the spoil. Instead, you can use driven precast piles on some contaminated soils. This means you don't have to dig out any soil to make space for these piles. Rather, you simply hammer them into the ground. You don't have any waste soil to deal with at the end of the process.

2. You Don't Need Extra Supports

If you're working in soft or sandy soil that isn't densely packed, then you have to mitigate against collapse when you plan your piling strategy. For example, if you'll bore holes before you insert piles, then you'll have to add supports in the hole as soon as you start to drill. If you don't, then the surrounding soil will simply collapse into the space and fill it up again.

However, if you use driven precast piles, then you don't need additional supports. The piles come ready-made, so they can stand strong and firm as soon as they go into the ground. Plus, they have a steadying effect on loose and soft soils.

As you hammer a pile into the ground, it compresses the soil it touches. This action forces some soil downwards and compacts it to make it firmer. Some soil is pushed around the shaft of the pile where it compresses.

3. You Get a One-Size-Fits-All Solution

Sometimes, you have to have a multi-pile plan for a build. For instance, you might need to work with various soil types or to create different levels of piling support on different parts of your project. If you use more than one type of piling, then your costs will increase. If this is the case, you might have to hire or buy different equipment, machines and materials for each type of pile.

Driven precast piles could fit all your needs. They'll work well across your site. You can also have them individually made to fit all your structural specifications.
