Austin and Central Texas abounds with geologic faults, the most prominent of which is the Balcones Fault, or “fault system”. These faults are especially common in a band, which runs north and south through Austin and similar areas in Georgetown, Round Rock, Buda, Kyle, San Marcos, New [...]
This subject has received attention from many sources for many years, but nevertheless remains a hot topic with regard to design and construction of lightly loaded, shallow foundations in Central Texas. The prime design problem for these foundations is swelling or expansive clays. A shallow [...]
Excavations are common on construction sites in the form of pits, trenches, and cuts adjacent to a hillside. Excavations are necessary for construction but can be dangerous. Stiff to hard clays seem very strong and will stand temporarily on vertical cuts for great depths. Clays [...]
Shrinkage cracks in concrete slab-on-ground foundations are a significant public relations problem to home builders. All concrete will shrink during the curing process which lasts up to a year after the time concrete is placed in the forms. Curing involves loss of water from within the concrete, [...]
When has a foundation or any other structural unit failed? There are three categories in which a structure could be placed with regard to structural performance:
Major distress and distortion

Wood frame construction is used practically 100% in single family and many multi-family residences. In addition, many smaller commercial structures use wood frame. Poor construction is usually the cause that permits water entry and long term dampness in wood framing. This is especially prevalent at [...]
Trees are common fixtures around the constructed environment and greatly enhance the livability and value of homes, offices, shopping centers, and other facilities used by man. If you have a shallow soil supported foundation or slab, or other near surface construction such as pavement in conjunction [...]
Steel structural framing has been used for many years in commercial construction. It is only used rarely for residential construction. The main reason appears to be that “it has always been done that way”. Another reason is probably that homebuilders do not have access to subcontractors [...]
Of the various types of balconies, the overhanging or cantilever types are potentially the most dangerous. Balconies can be found on single family dwellings, but most frequently are found in condominiums or apartments. A balcony can totally collapse if it becomes structurally unsound. Many deaths [...]
Austin has one of the most geologically diverse small regions to be found anywhere in the world. The many geologic layers, folds and faults cause different types of soil to outcrop in great profusion in this region.
Many people have heard of the Balcones Fault. This is a system of many faults that [...]
Most single and multi-family residences and significant number of small to mid size commercial structures utilize wood framing for structural support.
Timber Framing - refers to heavy timber 8" x 8” or larger.
Lumber - surface finished (S4S) wood members equal to or smaller than 6" [...]
One of the more disagreeable features of construction concrete is its ability to generate cracks. Cracks are of several varieties. Some are very fine, almost invisible to the naked eye, some are large and ominous looking. There are two basic types of cracks; the first type is shrinkage related while [...]
