Shear Walls & Columns

Rebar is standing tall and concrete is being poured. After digging in the dirt for weeks, we are finally coming out of the ground with Shear Walls and Columns. The soil in this area has a large amount of rocks. The ground is affectionately known as “potato” dirt. Unfortunately these little potatoes can be as large as 4’ in dia., which makes shoring piles interesting to say the least. Not to mention the spread footings end up being over excavated as the soil will not maintain a true edge. Although the foot print of the site is around 40,000 sf there is only one ramp access and with the large size of the footings and numerous columns, real estate in the hole is at a premium.
