ICC-ES AC358 addresses the corrosion protection of steel helical piles by establishing specific mandates for material thickness and coatings based on three distinct soil corrosivity categories. These requirements ensure the structural integrity and long-term durability of the foundation in various environmental conditions.
The protection strategies for each category include:
By following these thresholds, the AC358 standard ensures that helical piers resist section loss over time, preserving the load path from the structure to the bearing stratum.
Whether you need a sump pump for your Denver basement depends on your property’s specific water table and foundation type. Because Denver features expansive clay soils and variable groundwater levels, a sump pump is often a critical component of a…
In Colorado, particularly in the Denver area, perimeter drains prevent foundation damage by actively managing groundwater and relieving hydrostatic pressure. This is critical because the region’s expansive clay soils absorb significant moisture, causing them to swell and press against foundation…
Installing a vapor barrier in your crawl space is highly recommended to control moisture migration and protect your home’s structural integrity. While drainage systems manage liquid water, vapor barriers address moisture in its gaseous form. According to industry standards, here…
Poor drainage contributes to foundation settlement through a destructive cycle of soil movement and excessive pressure, particularly in the Denver area’s expansive clay soils. When water is not properly directed away from a home, it creates several structural threats: While…
The cost of installing a French drain around a foundation in Denver is hard to pin down exactly, actual project costs can vary based on several factors, including site conditions, soil composition, and the specific scope of the project. While…
