What is Foundation ?

Foundation is the interface between the structure and earth. It must be capable to adequately transfer the worst load case scenario from the structure to the soil. The worst load case scenario is a combination of loads from building own weights, inhabitants, and all objects that impose gravity load, and all forces imposed from the surrounding environment such as hurricanes, ocean waves, and earthquakes. The type, size, and specifications of foundation system depend on the worst load case scenario and on the characteristics of the underlying soil. Understanding the soil conditions and the design and analysis of a proper foundation system are the most crucial aspects of structural design.

Foundation Common Problems

Foundation systems are designed and built to function throughout the life expectancy of a structure. Exposure to adverse soil conditions (e.g., sinkhole presence) can result in unstable foundation causing downward movement (settlement) or lateral movement (bowing). Foundation settlement exhibits diagonal stair step cracks and vertically sheared wall blocks. Bowing foundation exhibits long horizontal crack extending from "near" one end of the wall to "near" the other end of the wall. The crack ends in diagonal stair step cracks leading to the top or to the bottom of the wall. Foundation problems should be treated promptly before the damage leads to irreversible failure.

Foundation Common remedies

A typical repair of foundation settlement is to install a series of steel underpinning piers below the affected foundation area. The installation involves the pushing and turning of anchors into the stable (or stabilized) subsoil until the required bearing capacity is reached. Adjustable brackets are then attached to the foundation of a jacked up structure, and then secured to the anchors while lowering the structure slowly to allow for load shifting to the anchor. This remedy creates a nonhomogeneous soil reaction to foundation system increasing the future risk of uneven building settlement. At Universal Engineering, we have the expertise and experience to assess the risk and recommend a cost effective solution. View our typical repair recommendations.

Foundation bowing walls can be repaired by Installation of a series vertical strut or I-beams, wall anchors, dead-man anchors, and or carbon strips. Because each type of insertion has its pros and cons for a given situation, a specialized engineer knows how to optimize the selection of one method over another for a given situation. At Universal Engineering, we are equipped with the knowledge and past work experience to determine the most appropriate remediation method based on a visual observation and analysis of the failed wall.

At Universal Engineering, We have experts in soil mechanics, soil structures, and foundation design (view past projects ). Our design proceeds in the following steps:

1. Collect or calculate the structure loading data
2. Investigate and determine soil characteristics.
3. Based on (1) and (2) Select Foundation system and/or identify best remedy.
4. Based on (3) Perform design and analysis and provide a cost effective solution.

Recognizing the critical and urgent nature of foundation design and repairs, we constantly update our toolbox with the most up to date leading edge design software technology and apply the state of the art techniques in foundation design and repairs.
