Guidelines & Recommendations After a Helical Pile Installation

We’d like to touch base on some important points to follow after a helical pile installation. Proper care is essential to ensure the longevity of any structure, whether you're building a deck, modular home, shed, or any other type of construct. To help you avoid common issues, we’ve listed key guidelines and recommendations to follow.

Here’s what you need to know:

Construction & Maintenance Phase

It’s imperative to maintain a minimum clearance of 6 inches between the ground and all structures, keeping in mind that the top plate bracket should never be buried. This provides proper spacing between building elements and the ground, while also allowing for ground expansion during different weather conditions.
Ex: frozen ground and/or soil moisture

Note:

• A minimum clearance of 6 inches between the ground and all construction features, such as skirting, beams, joists, or columns, is also necessary.
• Once the structure is in place, refrain from backfilling the area and burying the piles and space with objects, pavers, earth, or other materials. The 6” clearance must be maintained at all times.

Staircase Installation

If a staircase is connected to your structure, we also highly recommend installing TMP’s helical piles under the last step, again keeping a minimum clearance of 6 inches (to the ground) to ensure proper stability and support. If that option isn’t feasible, consider using a hinge system directly on the staircase to provide a mobile joint. Either of these methods will accommodate potential movement and prevent any shifting or uneven settling.

Storage

When storing items underneath your structure, it’s also important to reserve a minimum of 6 inches of space between your stored items and the structure itself. The reason is, that in regions where you have freeze/thaw cycles or swelling clay, ground movement can potentially push the objects upwards against the structure. Important to note: the piles themselves won’t be displaced, but the structure itself might be affected if the space distance isn’t respected.

The most important takeaway from this article is your attention to detail and taking the precautionary steps from the guidelines above. These key suggestions will contribute to the longevity of your project, avoid common issues, and provide adequate storage space without causing overall damage.
