Civil Membrane Inspection and Testing

Water gently running off of a roofing membrane is one thing. Fluids constantly pushing on a membrane from the inside of a holding tank at exteme pressure is a different animal all together. If problems aren't found you get more than a leaky roof! You either lose a valuable commodity or have a dangerous by-product leaking into the environment - or worse yet into the facility itself. You can ill-afford either. Gaussan Technologies has the experience in using a wide array of testing procedures that can determine membrane fitness to protect plant and community.
VOC and Gas Barriers


Indoor air quality (IAQ) has become a major concern for owners and new and existing buildings. Foundations are being designed with barriers to VOC's and other soil gases that will protect the occupants and the insured from claims resulting from IAQ issues.


The barrier shown above is a science center in New England that had VOC and radon issues. Gaussan designed the barrier and electrically tested the construction. The result was zero readings in both radon and VOC.


Corrosion and Containment Linings


Tanks, pipes, headworks and flow channels have been lined with various polymeric sheet materials for over 70 years. As a result, inspection of these linings is occuring more frequently as plants get upgraded due to changing demands in water and wastewater treatment technologies.


Gaussan testing services can determine if the linings are sound, if the liners can be repaired and what repair procedures should be implemented.



Concrete Protective LInings


Concrete protective linings are used in situations where the lining is required to lock into the concrete, thus allowing the liner to "hang" on the concrete to resist creep and backpressure.


These lining require specialized knowledge, and full testing provided by Gaussan Technologies reflects our 3 decades of experience with different products from all manufacturers of these materials.


The project shown above is a  subgrade slab supported by piles under a building built over an abandoned landfill with over 12" (30 cm) of expected settlement.
