Frequently Asked Questions
Load bearing capacities are based on the soil condition the Screw Pile is installed into and the material composition of the Pile itself.
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.
Yes, a Ground Screw can be installed in any type of ground condition, including gravelly soil, through large boulders or even solid bedrock. Without the help of pre-drilling equipment, a Ground Screw will be limited to rocks smaller than a few inches in diameter and will only push past small rock if a majority of the surrounding material is non-rocky and offers the threads of the Ground Screw good bonding material. With the help of pre-drilling equipment like rotary hammers, or pneumatic drills, a pilot hole can be drilled to either fracture or fully drill out the encountered rock. The Ground Screw can then be installed through, or into the rock.
Yes, a Ground Screw can be installed in any type of ground condition, including saturated soils like shore sides, marshlands or lake bottoms.
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.
We have completed projects from Nunavut to Puerto Rico, Prince George to Montreal and are able to service any area required. Our head office is located near Toronto, Ontario.
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.
The main difference lies in the threading mechanism. The Ground Screw features continuous fine threading much like a woodscrew, while a helical pile features a large helical blade as found on an auger.
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.
The Ground Screw will try to go the path of least resistance and try to work around smaller roots without much obstruction or deflection. Should a larger root be encountered close to a large tree, it may be possible that the Ground Screw will be refused.
Continuous threads on a tapered body allow the Ground Screw to thread itself into the ground, compacting the surrounding area and offering incredible loadbearing capacities with very little ground penetration. Helical piles disturb the ground during installation and typically require a much deeper pile installation. Because of the disruption in the native ground, lateral stability is significantly reduced. On the contrary, a Ground Screw provides a tight bond with the surrounding soil, offering instant stability.
