Piering
Piering is a method of concrete leveling that addresses foundation issues by installing piers beneath the affected areas. This technique is utilized when traditional leveling methods are inadequate or the sinking has progressed significantly.
Benefits of Piering
- Restores structural integrity by stabilizing the foundation.
- Prevents further sinking and damage to the property.
- Increases the property’s value by addressing a major structural issue.
Process of Piering
The piering process typically involves the following steps:
- Assessment: An engineer or contractor evaluates the foundation and determines the appropriate number and placement of piers.
- Excavation: Holes are dug around the affected areas to expose the foundation.
- Pier Installation: Steel or concrete piers are driven into the ground until they reach stable soil layers.
- Lifting: Hydraulic jacks are used to gradually lift the affected areas and restore them to their original position.
- Grouting: The holes around the piers are filled with grout to ensure stability.
Types of Piering
There are two main types of piering:
- Push Piers: These piers are pushed into the ground until resistance is met.
- Helical Piers: These piers are screwed into the ground like large screws.
Choosing Piering
Whether piering is the most suitable concrete leveling solution depends on several factors, including:
