Attendance has been good with 15 to 30 attendees at each meeting and the attendees are always an even mix of students, staff and senior professionals. Our e-mail list has increased by one-third and two student chapters are possibly starting as a result; one at Sacramento State and one at UC Davis. The talks have been held at the URS office in Natomas, CA all due to the efforts of the President Matt Weil (from URS). CalGEO would like to thank Matt for stepping up as the group’s President and for the generous donation of meeting space by URS.

It has been an exciting year hosting these guest speakers and hearing their talks. If you have a topic you would like to see or have a topic you would like to present please contact: or See you on third Wednesdays except for in December when the group will be taking a holiday break from meetings.

Expansive Soil’s Effect on Vapor-Proofing: Protecting the Sixth Side

By: Stego Industries, LLC


Stego Crete Claw Installation

Crete Claw Installation

Expansive soil can disrupt the integrity of the under-slab vapor-proofing system and increase the likelihood of a number of costly moisture-related issues. That said, techniques and technologies can be utilized that help to maintain the effectiveness of the under-slab vapor barrier. Stego Crete Claw allows the vapor barrier to adhere to concrete slab— and this technique not only satisfies the requirements of the prevailing installation standard (ASTM E1643-11 Section 6.4) but helps to maintain a continuous under-slab vaporproofing system in light of future soil movement.

Forest Fires & Respiratory Health Facts

∼Courtesy of The American Lung Association


California wild fire

Wildfires are an ongoing concern, particularly at this time of year in California. During a wildfire, people all over the area may be suffering the effects of forest fire smoke. The American Lung Association urges those with respiratory problems such as asthma, emphysema, and bronchitis and also those with chronic heart disease to monitor their breathing and exposure to airborne matter. If problems develop call your physician immediately.

General recommendations:

People living in close proximity to the fire-stricken areas should remain indoors and avoid inhalation of smoke, ashes, and particulate matter in the area. Ordinary dust masks, designed to filter out large particles, will not help as they still allow the more dangerous smaller particles to pass through. Special, more expensive dust masks with true HEPA filters will filter out the damaging fine particles but are difficult for people with lung disease to use. Consult with your physician before using a mask, especially if you have a lung disease.
If you live close to or in the surrounding area, it's recommended that you refrain from exercising outdoors, especially if you smell smoke or notice eye or throat irritation.
Extra precaution should be taken for children, who are more susceptible to smoke because their respiratory systems are still developing and they breathe in more air (and consequently more pollution) per pound of body mass than adults.
When driving your car in smoky areas, keep your windows and vents closed. Air conditioning should only be operated in the "recirculate" setting.
