Project Description

Single Drill Pier System

 

 

For homes and light commercial buildings, single drill concrete piers are concrete columns that are formed by drilling holes into the ground between 9- 12 feet deep and pouring liquid concrete 3500 psi into holes and are reinforced with steel rebars that are tied together and lowered into the hole. Creating a perfect vertical shaft that is between 10-12 inches in diameter.
Pros
1. Can guarantee greater depth than pressed pilings.
2. Less lateral movement
3. Less structural stress
Cons
1. Waiting time of 5-7 days for concrete to cure after pouring.
2. Larger amounts of soil must be removed.
3. For Double Drill concrete piers pricing is higher.
