Screw Piles in Cochrane, AB

Screw pile foundations in Cochrane. Dense glacial till and shallow bedrock require higher installation torque — we size for it. No travel charge.

Chinook Piling installs engineered screw pile foundations across Cochrane and Rocky View County. Decks, garages and grade beams, home additions, and underpinning for footings that have started to move — all torque-verified, with stamped drawings where the permit calls for them. No travel charge, and quotes back inside 48 hours.

Building on Cochrane Ground

Ground conditions

Dense glacial till with cobbles and shallow bedrock as the ground rises west toward the foothills. Requires higher installation torque and heavier pile shafts than Calgary clay.

Who issues your permit

Town of Cochrane is the authority having jurisdiction here. Inside town limits the authority is the Town of Cochrane; step outside and you are in Rocky View County, reviewing to its own requirements. That boundary matters more here than almost anywhere else we work, because so much Cochrane-addressed building is acreage building. Expect a structure on a meaningful slope to attract more engineering attention than the flat-lot equivalent — reasonably so. Our drawings are stamped by an Alberta P.Eng. through an APEGA permit-holding firm, and every pile is delivered with its torque record, which in this ground is also the document showing where refusal occurred and what was done about it. Fees and timelines come from the Town or the County.

What we install here

Sloped-site decks, walkout foundations, cabins and acreage builds on rocky ground.

The ground under Cochrane

Cochrane is where Calgary clay stops being the right mental model. The town sits at the base of Big Hill in the Bow valley, and as the ground rises west toward the foothills the soft lacustrine clay gives way to dense glacial till packed with cobbles and gravel, with bedrock progressively closer to surface. That is good news structurally — strong ground with real capacity. It is simply harder to get a pile into.

The difficulty is the practical story here. Dense till takes higher installation torque and often a heavier shaft than the same load would need in Calgary, and it carries a genuine risk of refusal: the pile meets a cobble or boulder it cannot pass, short of design depth. That is a normal outcome in this ground rather than a failure, and the honest responses are to relocate the pile within tolerance, change the pile configuration, or tell you a screw pile is the wrong foundation for that spot.

The town also spans real elevation change, so it is not one ground condition. Down near the Bow you get river alluvium and a shallower water table; up on the hill you are into till and cobble. Two Cochrane addresses can present completely different problems, which is why we ask where on the hill you are before saying anything specific.

What gets built here

Sloped lots define the work. Walkout and side-slope sites mean deck structures standing two and three storeys off grade at the far end, with pile lengths varying substantially across one frame and lateral load a flat-lot deck never sees. Getting equipment onto a steep back yard is its own problem, and a machine that fits the access is not always a machine that can generate the torque this till needs — we size for both before quoting.

Out toward Highway 22 and the acreages the mix is cabins, shops and post-frame buildings on exposed ground. West of town the wind is a design case in its own right: tall, light structures on open foothills sites need documented uplift capacity, and a helical resists tension directly without a mass of concrete to hold it down.

Depth is decided by installation torque, not a fixed number — a pile is driven until torque confirms the engineered capacity. On ground like this that can mean two piles metres apart finishing at different depths, and both being correct. How deep screw piles go in Alberta .

Where we work in Cochrane

This map shows the area we serve, not a shop you can visit. Chinook Piling is a mobile piling contractor — the crew, the machine and the piles come to your site, so we work out of trucks rather than a storefront. We cover Cochrane and Rocky View County as part of our regular working radius, which is why there is no travel charge on quotes here.

Permits for work shown on this map are issued by Town of Cochrane.

Screw Pile Questions in Cochrane

How deep do screw piles need to go in Alberta?
Screw piles must extend below the frost line, which runs 1.2 to 1.8 metres deep in the Cochrane area. In practice the final depth is governed by installation torque rather than a fixed measurement — the pile is advanced until it reaches the torque that correlates to the engineered capacity required. Two piles on the same site can finish at different depths and both be correct.
Are screw piles cheaper than concrete?
On materials alone, concrete can look cheaper. Once you add excavation, spoil removal, forming, and the days lost to curing, screw piles are usually competitive and often less — and you can build on them the same day they go in. We will give you both numbers honestly rather than steering you.
What are the downsides of screw piles?
They are not right for everything. Very rocky ground or shallow bedrock can stop a pile short of depth, which sometimes calls for a different pile size or a different foundation entirely. They also need proper engineering to be worth anything — an unverified pile with no torque record is just a post in the ground. If piles are the wrong answer for your project, we will say so.
Can screw piles be installed in winter?
Yes. Frozen ground is not a barrier — piles are installed year-round in Calgary, which is one of the main advantages over concrete. Winter is often the easiest time to book us.
Do you charge a travel fee to Cochrane?
No. There is no travel charge to Cochrane or anywhere else in our service area.
