Let me first explain foundation underpinning before we get into the different concrete foundation Underpinning techniques. Concrete Rectify Underpinning Melbourne can be used to strengthen a foundation which is too weak to support a building.
Underpinnings are necessary because of changes in the use of the buildings over the years. Many buildings have been upgraded to a higher level. It was not intended for the extra weight to be placed on the foundation. Other factors, of course are due to erosion. Before the building was constructed, it was not properly researched.
In the hopes of preventing future foundation failure, soil sampling and engineering reports have become more common than in the past.
Reinforce foundations by strengthening the underpinning
Many ranch style homes, particularly here in Long Island were constructed on a slab of concrete with a footing made from concrete. The homeowners then added an additional story, without considering how much weight would be placed on their foundation.
Concrete engineering firms began to recommend foundation underpinning in order to strengthen and reinforce the foundation. A licensed concrete contractor specializing is foundation repair and construction will perform the underpinning.
Concrete Foundation Underpinning Repairs Faulty Foundations
Concrete Foundation Underpinning involves extending the foundation of a building horizontally and/or vertically. Structural engineer will determine the amount of concrete to be used in the direction that the foundation develops.
The engineering firm will give concrete contractors plans to follow in order to strengthen and stabilize the foundation.
What To Do To Support A Foundation
In construction, foundation underpinning can be used to strengthen and reinforce an existing structure. A licensed, insured and specialized concrete company that is experienced in building foundations and repairs will perform the underpinning of a foundation.
The foundation of a building can be extended both vertically and horizontally. A structural engineer will diagnose the problem and determine the amount of concrete to use, as well as the direction the foundation should be extended.
Concrete construction companies will be provided with detailed plans by the engineering firm to follow in order to maintain the strength and stability of the foundation. The concrete underpinning strengthens and reinforces an existing building’s foundation.
The Foundation Footing
Three Foundational Methods.
1. There are many different underpinning techniques. The three most common methods of underpinning foundations. Mass concrete underpinning is the most popular. To avoid further damage to the foundation, the excavation is done in alternate sections. After the excavation, concrete is poured into the area.

2. Screw pilings, also called helical piles, are another method of foundation. The piles are installed by screwing them under the foundation of the building and in different steps, until stable soil has been reached. The foundation is then screwed with these heavy, galvanized screws.
Helical pilings are a great alternative to traditional piles. With the right equipment, they can be quickly installed and with minimal noise. The brackets are galvanized and screwed into the soil.
The third method of underpinning is called beam and base foundation. The load is transferred by placing a reinforced concrete beam beneath the concrete piles.

Helical piles are screwed in the ground to a depth of about 3 feet. This is the maximum height that they can be inserted into soil.
The foundation is then secured with large galvanized brackets. This prevents any movement. Helical piles offer the most cost-effective alternative to fix foundations which are sinking or broken.
Helical Pile Underpinning is a method of foundation underpinning.
Helical piles are also called screw pilings. The piles are screwed in the soil below the foundation of the building and installed at different depths, until stable soil has been reached.
The foundation is then screwed with these galvanized screws. Helical piles offer many benefits over wooden pilings. With the right equipment they can be quickly installed without much vibration or noise.
This is an easy-to-understand view of foundation brackets and helical pilings. The unique view of the helical piles simulates underpinning using helical piles.
