Another tough helical deck pier installation…

The versatility of our small helical pier installation machine revealed itself again on a recent winter job. As far as job sites go, this one had multiple challenges – tight access, a steep hill and piers installed on multiple levels.

First we had a very tight corner to negotiate and we just were able to clear the many obstacles.

Our machine can easily get through 36″ openings and in some cases we can actually sneak through a 30″ wide opening. The challenge on this job was negotiating through the narrow passage to the back of this residence. The edge of our ‘path’ was on a very steep hill and the general contractor built us a temporary road to allowing us access.

Once in the yard, the job got even more challenging. The new deck will be situated above this steep hill and Techno Metal Post Alaska was the only contractor able to access this difficult work site. The other option was to hand dig sono tubes to a depth of 5′. After installing the lower posts we needed to get the machine back up to street level. We set one of our larger P3 posts as an anchor before heading down the hill. Once back up the hill, we just uninstalled the temporary pier.

Notice that we are working in winter. We found frost down to about 24″ and were able to thaw the ground quickly, allowing us to install 8 posts in a single day; even with the difficult access conditions.
