Frost and heaving are always a factor when doing decks and fencing in Winnipeg. That's why Clean Cut Decks & Fencing recommends using screw piles. They are cost efficient and effective!
When building a deck in Winnipeg, we at Clean Cut Decks & Fencing recommend using screw piles. You will want to use piles rated at a 5,000 lbs load capacity. The city of Winnipeg and most surrounding areas will require this when building a deck larger than 300 sq ft, a two story deck, an enclosed deck or a deck near a river. They will also require you to get geo-technical investigation and engineer stamped letter so you will want to budget roughly $1000 for those services. Our rate for a 5,000 lbs capacity pile is $300 installed in Winnipeg.
Screw-piles and helical anchors are usually installed using conventional construction equipment such as a track excavator or a mini-excavator equipped with an appropriately sized low speed high torque hydraulic motor. There is no need to mobilize special equipment such as a large drill rig. This makes for fast and inexpensive mobilization, We can respond and be on site quickly. Typically only an operator and one laborer are needed. Large load capacities can be obtained using relatively small installation equipment.
Installation rates typically are on the order of 6 to 10 rpm, which means that it only takes about 30 sec. to advance a screw-pile or helical anchor a foot, or about 5 min. per 10 ft. of length. Depending on the extension section being used, the crew can attach a pipe or square-shaft extension in about a minute, so a 50 ft. installation should only take about 30 to 40 min. The installation is not dependent on weather conditions with most installations proceedings even in marginal conditions.
