1810.2.12 Protective treatment of deep foundation materials.
BC § 1810.2.12
Where boring records or site conditions indicate possible deleterious action on deep foundation elements because of soil constituents or other aggressive environmental factors (such as chemical seepage, the presence of salt water, electrical current, changing water levels or other factors), the deep foundation elements shall be adequately protected by materials, methods or processes approved by the engineer. Protective materials shall be applied to the deep foundations so as not to be rendered ineffective by driving. The effectiveness of such protective measures for the particular purpose shall have been thoroughly established by satisfactory service records or other evidence. Deep foundations installed in ash, garbage, or cinder fills; deep foundations that are free-standing in or near a seawater environment; deep foundations used for the support of chemical plants or coal storage; deep foundations under similar conditions of chemical seepage or aggressive action; and deep foundations that are used for support of electrical generating plants, shall be investigated regarding the need for special protective treatment. Where special protective treatment is indicated by the engineer, such deep foundations shall be protected against deterioration by encasement, coating or other device acceptable to the engineer.
