Pacific Security Fence West | Fences & Gates in San Martin, CA

San Martin has a mix of clay and sandy loam soils that expand and contract with seasonal moisture. This shifting, combined with heavy winter rains, can loosen the gravel or concrete footing around your posts. Over time, this movement causes posts to lean or sink. We solve this by setting posts deeper—often below the frost line—and using a wider concrete base with proper drainage gravel to redirect water away from the post base.

Look for flaking red or brown rust, pitting in the metal surface, and thin spots where you can see light through the metal. If you tap a rusted area with a hammer and it crumbles, that section is compromised. In many cases, we can replace only the rusted rails or panels rather than the entire fence, using galvanized or aluminum components that resist San Martin's damp climate much better.

Properties near waterways like Coyote Creek have loose, silty soil that moves easily. We recommend setting posts in concrete that extends at least 24 inches deep and flaring the bottom of the pour to create a 'bell' shape for extra hold. We also install drainage pipe around the post base to carry water away, preventing the soil from washing out around the concrete. This stops posts from shifting even after heavy rain.
