Piering - Foundation's Failure Solution

By: Carmelo Middleton

Foundation failure can be threatening if you don't correct the problem. Your house might actually become crooked. Unfortunately the indications of foundation failure don't present themselves until the issue has become major. These signs included cracked walls, uneven flooring, cracked tiles and windows not closing right. If you notice any of these in your house, it would be sensible to call an expert to come in and do an investigation to find out for sure if you maybe have foundation failure.
This is due to one thing. Most often or not the soil that foundation is laid on is the culprit. Often soils that are under foundation that have issues contain clay. Once this clay is wet, it often will not dry the same across the board and this can end up in the problem of a failure. The factors that can make contributions to the soil getting wet is many things, weather, poor drainage, pluming leaks, and even roots from trees can upset the soil under your foundation.
The solution to foundation failure is something by the name of Piering or underpinning. Piering is the method of lifting and stabilizing your foundation. There are customarily 2 styles of steel piers used for this. Both are acceptable though steel piers used for a specific foundation. Talk to your contractor to find out which pier he feels is best for your house.
First there are resistance piers which are hydraulically pressed straight down into the soil with the weight of the structure as counter balance. These piers go down until it reaches a layer of soil that is hard enough to support it. They work best in situations where the structure the needs to be raised has a very heavy load constraint.
Next are helical piers which are hydraulically twisted into the soil similar to how a corkscrew be raised has a drill works. These piers consist of flights which may pull the pier into the ground. As with resistance piers the helical piers will stop going down once they reached soil that is heavy enough to support it. They cannot be pulled or pushed out. Helical piers are the most useful on slopes or hillside because of how they screw into the ground.
Helical piers can also come as pre-construction helical piers. These are installed where there might be some debatable soils. Some soils may not be sufficient to how they screw into the load of the structure and this as pre-construction piers would come in handy. They help stop any future foundation failure.
After the piering are installed your contractor should give you a detailed report the load of the exact location of the installed piers and also explain the hydraulic measurements. Keep this report with your important records.
The price of underpinning can alter depending on the type of piers you are using. Most ordinarily used are the installed piers or steel helical piers. Your price will also vary depending on how deep the piers need to go down. The deeper the depth the more cash it is going to cost. Finally you have to observe the labor costs. This isn't job where you wish to take the inexpensive way out. Yes this may be a costly job, but think of the price if your place is destroyed by foundation failure.
