What are the load capabilities of a Ground Screw?
In general, Ground Screws are able to meet load requirement for compression, tensile & lateral loads on most residential structures.
The easiest way to think of Ground Screws, is to compare them to traditional wood screws installed in lumber and are equally dependent on the material they are installed into. A wood screw in a rotten piece of 2×4 will not hold much, but the same wood screw screwed into a board of cherrywood, will offer incredible strengths.
Should a single Ground Screw not be enough to withstand the required load, groups of piles can be installed and connected by steel plates or beams.
Our installations are fully engineered on a project specific basis, factoring in local conditions.
Can a Ground Screw be used in rocky soil conditions or even bedrock?
Can Ground Screws be used in wet soil conditions?
The BAYO.S Ground Screw features an engineered extendibility feature, that allows for on site length extension of the Ground Screw shaft. This allows the Ground Screw to be installed deeper, until the required ground resistance has been achieved and a stable foundation support has been created.
The BAYO.S system also features add on helical blades that can be utilized in extremely wet conditions, providing additional compressive strength in weak soils.
What areas do we service?
In our daily operations, we service the GTA, Simcoe, Muskoka, Haliburton, Peterborough, Dufferin, Gray, Parry Sounds, Manitoulin, Cochrane, Thunder Bay, Northumberland, Lennox & Addington, Hastings, Prince Edward & Vancouver Island.
What is the difference between a Ground Screw and a Helical Pile?
The Ground Screw forms a tight bond with the surrounding material and does not disrupt the soils natural strength, therefore achieving foundation stability with much less required soil penetration.
What kind of machine is required to install a Ground Screw?
How does Ground Screw pricing compare to concrete and helical piles?
When comparing the Ground Screws’ raw material cost against concrete, it is more expensive, but offers long term quality benefits like no frost heave, no post rot and the potential to be removed with ease and re-used.
Compared to Helical Piles, the biggest advantage is staying within budget. It is a fact that Ground Screw foundations do not have to be installed as deep as Helical Piles because there is much more soil displacement and compaction occurring during installation. Therefore in many cases, a Ground Screw can reach its required ground resistance significantly faster than a Helical Pile.
It is very rare in our construction process having to issue change orders for deeper foundation requirements without anticipation.
The BAYO.S DIY line is ideal for small residential constructions, without the need for specialized installation equipment or a certified installer.

What are disadvantages of Helical Piles?
In rocky terrain, with larger boulders, the pile gets deflected off its original vertical axis. One of two things will occur: The original foundation location will be missed and the pile will be installed in the new position; or – The helical pile installer will try to force the pile around the obstacle and continue the installation under pressure from the equipment. This sometimes works, but significantly stresses the material and greatly disturbs the surrounding soil.
Because of this soil disturbance, the previously existing natural strength in the ground is taken away. Water will always try to follow the path of least resistance and will funnel along the Screw Piles body, making the area more susceptible to frost heave, until the area has settled again.
What are advantages of Helical Piles?
In soft or disturbed soils, where a thin Ground Screw thread would not form any contact with compressed surrounding soil, a Helical Pile is the better foundation choice.
To what height can Ground Screw Foundations be installed?
Elevations from below grade to several meters elevated are possible, but will require additional hardware like cross-bracing.
