Building on Techno Metal Post- Managing Lateral Loads

Building a Cottage or a House? Start with a Solid Foundation!

Your home’s stability starts at the base, and choosing the right type of foundation ensures stability, durability, and peace of mind for years to come. More and more homeowners are turning to Techno Metal Post’s helical piles because they provide excellent structural support and withstand forces from wind pressure, occupant loads, and even seismic activity.

The Right Model for Every Project

Choosing the right pile model for your project is essential to offset these forces, and Techno Metal Post offers a range that adapts to your construction’s size and weight.

Owners or builders often request a specific height under a free-standing cottage or house to facilitate access to utilities and to have a good distance from the ground. When building on a helical pile foundation, ensure the above-ground pile height is kept as low to the ground as possible. This minimizes lateral movement risks and reduces the need for bracing or larger piles.

When buildings have an elevated structural system already in place- such as cottages or homes in high-water table areas or in a particular environment, adding a bracing system (metal bars that connect the piles) is required for extra stability.

Details That Make a Difference

A Foundation You Can Trust

Provide a New Foundation for Your Cottage

Many older cottages were built at a time when foundations didn’t get the attention they deserved. They were often built with the materials that were on hand, like concrete blocks or wooden beams, but weren’t designed for the long haul or to bear the weight of the structure.

Today, these properties have grown significantly in value and are being used either as a primary residence or a comfortable three-season retreat. For this reason, the importance of a solid and lasting foundation is where Techno Metal Post’s helical piles play an important role.

In some areas, local regulations don’t allow for demolition or a rebuild, but that doesn’t mean your cottage can’t be upgraded! You can invest in a proper and reliable foundation solution while preserving the existing structure.

Why Choose Techno Metal Post’s Helical Piles?

Plan Ahead Before an Installation!

What you need to know prior to a helical pile installation-

If you are planning a new construction or a renovation project with Techno Metal Post, you need to know the following: It is essential to check if your property has any underground utilities before installing the helical piles.

As with any excavation work, you must ensure that no utility infrastructure (such as water, sewage, electricity, gas or internet) is in the area where the piles are to be installed.

Whose responsibility is it?

Either the property owner or the contractor is responsible for verifying the site before the Techno Metal Post installer arrives.

As a rule, nothing should be closer than 1.2 m (4 ft.) from where the piles will be installed.

Getting started-

First, you must find and contact a local authority or utility locator that can provide you with the “locates” or necessary information. Here is a website that can guide you, free of charge, for the public area of your property (between the street and your property line) www.clickbeforeyoudig.com.

As for the property’s private area (between your property line and your house), you are responsible for checking that everything is safe. If you are unsure where the utilities run, you can call on specialists who offer underground infrastructure location services.

Why is this important?

A broken pipe or a severed electrical line can cause major damage and be expensive to fix. That is why proper planning and infrastructure verifications are essential before starting any work.

A High-Water Table and Your Foundation

A growing concern

Techno Metal Post is aware that currently, many people are living in high-water table zones.  Some are there by choice (coastal homes, cottages, etc.), while others come across these locations by circumstance.  Structures that weren’t previously in flood zones, now find themselves in these situations due to seasonal patterns, land development, or other causes. Also, regions where these tables were once “normal”, are now in areas where water is increasingly on the rise.

Zones with a high-water table are most common in low-lying areas or in locations where soil has poor drainage.  As a result, this can cause significant damage to homes and nearby structures. With this, there is an ever-growing need for secure, reliable, and durable foundations.

Techno Metal Post addresses this with our helical pile foundations. A perfect solution for protecting your structure/s and ensuring your home remains stable in high-water table areas that experience flooding issues.

 

Why install Techno Metal Post’s helical piles instead of traditional concrete footings in these conditions?

Installing a Techno Metal Post helical pile foundation allows you to build your home or other structures in any soil condition, even in a high-water table.  Our helical piles are ideal for challenging terrain, including flood plains, as they require no excavation.

There’s no avoiding that concrete footings require excavation, and doing so in high-water zones, creates challenges greater than expected. Factoring in the cost of time and labor, you also need to consider the following: Digging close to a high-water table allows water to flow freely, making pumping, drainage, and repair inevitable. Afterwards, footings must dry before pouring, and finally, the completed project must pass final inspection.

Our helical piles are simply screwed into the ground with our specialized equipment, which can access any terrain – wet, dry, or frozen. There is no digging or concrete involved, no mess, and no need for inspections which allows you to build immediately.

Your Techno Metal Post foundation remains strong, solid, and durable, and is able to withstand wet environments. Our recommended green polyethylene sleeve offers protection between the bogged soil (or direct water contact) and the pile, so there is also no risk of it lifting during the freeze/thaw cycles of winter conditions.

Techno Metal Post’s helical piles are the guaranteed solution to protect your home investment, whether you live along a riverbank, adjacent to a flood plain, or simply in an area with high-water tables.

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 structure. 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:

 

 

 

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.

Our Unique Polyethylene Green Sleeve

Let’s look at one feature that makes Techno Metal Post stand out from our competitors: Our high-density polyethylene green sleeve. It offers a unique benefit because of its design to reduce friction between the surrounding soil and the helical pile.

For over 30 years now, Techno Metal Post has promoted the use of their green sleeve in helical pile installations, particularly for those installed through a layer of soil subject to freeze/thaw cycles. When the ground freezes, it causes the soil to expand and push the ground surface upwards, resulting in frost heave. Expansive soil can also alternate between shrinking and swelling with seasonal changes in its moisture content.

Over time, we observed that using the green sleeve reduces the risk of piles lifting/heaving in winter and thus promotes their stability throughout the seasons.

During 2020, TMP undertook a process to characterize and quantify the positive effects related to the use of the green sleeve. A field load test campaign was completed in March 2022 by TMP and witnessed by a third-party laboratory. The objective was to validate the effectiveness of the green sleeve on our helical piles, models P1 to P5, for two different types of soil (granular and cohesive).

The test consisted of conducting pull-out load testing on pile shafts installed with and without a green sleeve. Based on the analysis of different results, the conclusion showed that friction can be reduced on average by 67% between the pile with a green sleeve and the frozen ground.

Important to note: Normally, helical piles are designed to be anchored in a stable layer of soil and installed below the frost line or zone of potentially swelling soil. Helices in a deeper soil layer resist uplift forces caused by frost or expansive soil. Adding insulation, especially when piles are installed under a concrete foundation, can also provide protection. That explains why some structures built with Techno Metal Posts have no sleeve.

However, for shallow applications of light loads, such as deck foundations, patios, or other residential structures, we recommend our high-density polyethylene green sleeve to reduce the effects of soil friction and expansive soil.

For those familiar with the installation of helical piles, the helix goes into the ground with ease until the minimum torque is reached. However, in some cases, the installer has to contend with some obstacles, making for a more challenging installation requiring some soil disturbance around the helix and pile itself.

Often observed with rocky soils, this shuffling, however minimal, can create a water infiltration point which reduces the helix's ability to regain vertical uplift force resistance. By winter, accumulated water has frozen, causing potential soil movement which increases the vertical friction force along the pile.

For such situations, Techno Metal Post's green sleeve plays an essential role: it acts as a barrier between the soil and the pile. The sleeve slides along the pile without compromising the stability of the pile.

The soil eventually and naturally reconsolidates with the seasons. This reduces infiltration while increasing the pile's capacity to withstand the vertical forces caused by the freeze. The need for a green sleeve is therefore essential for the first 2 to 3 years following installation.

Eventually over the years, the sleeve might gradually move upwards. Cutting off the excess with a utility knife will prevent excessive build-up on top of the pile as well as improve the aesthetic appearance.

In some cases, after several years, the sleeve may completely come off. By then, it won't be necessary. The soil will have completely reconsolidated around the pile, allowing it to absorb the vertical forces of the freezing conditions without it shifting.

Overall, adding the polyethylene green sleeve during a pile installation greatly reduces the risk of piles lifting/heaving in winter and allows the stability of your structure on a long-term basis.
