Slab on Grade Foundation – Advantages, Disadvantages and Uses of Slab Foundations
Slab on grade foundations are also commonly known as floating slab foundations. The foundation is formed using a mold that is set into the ground rather than digging a basement for the structure. There is no space between the ground and the poured concrete. Uses of Slab Foundations Slab foundations are used under the following […]
Two Column Footings – Basics of Combined Footing Design
It is desirable to design combined footing so that the centroid of the footing area coincides with the resultant of the two column loads. This produces uniform bearing pressure over the entire area and forestalls a tendency for footings to tilt. In plane, such footing are rectangular, trapezoidal, or T shaped, the details of the […]
Concrete Block Foundation – Advantages and Disadvantages of Concrete Block Foundations
Concrete block foundations are built using concrete blocks that are typically 8 inches by 16 inches. Although they do come in various sizes, this is the size that is most commonly used for foundations. The concrete blocks rest on a concrete footing that has been poured deep and wide enough to accommodate the load of […]
4 Functions Of Pile Foundation – Why Piles Are Used
When the soil beneath the level at which a footing or raft would normally be established is too weak or too compressible to provide adequate support, the loads are transferred to more suitable material at greater depth by means of piles or piers. The distinction between the two is somewhat arbitrary. What Are The […]
Comparative Study Between Combined Footing, Strip Footing and Mat foundation
Combined Footings Spread footings that support more than one column or wall are known as combined footing. They can be divided into two categories: those that support two columns and those that support more than two columns. Combined Footings – Two Column Two-column combined footings are seen become necessary in 2 situations: If columns are so close to […]
Spread Foundations – Types and When To Use Spread Footing Foundations
The horizontal outline of the most common spread footing foundation types are given. A wall footing is simply a strip of reinforced concrete, wider than the wall that distributes its pressure. Single-column footings are usually square, sometimes rectangular, and represent the simplest and most economical type. Their use under exterior columns meets with difficulties if property rights prevent […]
5 Common House Foundation Problems and Solutions
One of the biggest headaches that homeowners face regarding home repairs and maintenance is when the foundation of the house begins to shift or crack. There are usually simple and easy fixes for foundation problems if they are caught early enough. It is always good stewardship to check basement walls and foundations about once a […]
Common Methods Used For Bracing Sides of Shallow Excavations
For most structures, the foundations are established below the surface of the ground. Therefore, they cannot be constructed until the soil or rock above the base level of the foundation has been excavated. Ordinarily, it is not the function of the foundation engineer to select the equipment for excavating at a given site or to […]
How To Build a Building Foundation – 10 Steps
When constructing a foundation for a building, it is generally best to have a professional come in and do most of the work. There are some skilled do-it-yourselves out there, though, who can properly build a foundation for a small outbuilding. A civil engineer must to know the details of foundation construction as it’s the […]
Differential Settlement of Soil – Factors To Consider in Foundation Design
The substructure or foundation is the part of a structure that is usually placed below the surface of the ground and that transmits the load to the underlying soil or rock. 2 Important Factors in Foundation Design Regarding Settlement The two essential requirements in the design of foundations are that the total settlement of the […]
How To Build a Shed Foundation: 5 Simple Steps
When building a shed foundation, there are two basic categories: on-grade and frost-proof. Most sheds are built using on-grade foundations as they are the simpler of the two. Frost-proof or permanent foundations are much more difficult to build and they are strong and long-lasting. On-grade foundations do not require deep digging. To build a shed […]
How To Repair Concrete Foundation Cracks – 5 Simple Steps
Foundations will shift and settle over time and cracks will form. Many times minor cracks do not cause any really problems to the structural integrity of the structure. It is essential, however, to stop the cracks from spreading and becoming problematic in the future. It can be relatively simple to fix foundation problem that does […]
Foundation Crack – Cost of Cracked Foundation Repair
Cracked foundations can be disastrous for a structure. The most common cause of a cracked foundation is settlement. As the foundation shifts and settles into the ground over time, cracks can occur. Depending upon the severity of the settlement the cost of cracked foundation repair will vary. Cracked Foundation Repair Average Cost The average cost […]
