The Adobe Clay "Heave"
Mountain View is built on expansive adobe clay. This soil is reactive. Water increases its volume drastically. It generates massive upward pressure.
This force snaps concrete foundations and pushes monuments out of alignment. In summer, the soil shrinks and cracks. The foundation loses support and drops.
If you are searching for tombstone repair and restoration because a marker is heaving, adding dirt is useless. The clay will move again. We excavate the active soil. We replace it with deep angular gravel. Gravel is inert. It creates a static buffer that isolates the monument from the moving earth.
Irrigation "Flash" Scale
The water in the South Bay is mineral-heavy. Sprinklers hit 140-degree black granite. Flash evaporation occurs immediately.
The minerals fuse to the surface. This builds a hard white crust. It bonds to the silica in the stone. It looks like white cement splatter.
You cannot scrub this off. Mechanical abrasion will scratch the polish. We use specialized chemicals in our cleaning stone gravestones protocols. We apply an industrial descaler that chemically breaks the mineral bond. We turn the hard rock into a soft paste and rinse it away.
Live Oak Tannin Stain
Many local cemeteries, like Alta Mesa, are shaded by heritage Live Oaks. These leaves are acidic. Moisture leaches tannin pigment directly from the leaf into the stone.
It penetrates the granite pores. It creates a deep, dark brown organic stain. It dyes the stone matrix.
If you are searching for headstone cleaning services near me because the stone looks stained brown, that is tannin. We use a chemical poultice. We apply a paste that re-liquefies the pigment and wicks it out of the rock pores. We restore the natural color without bleaching the stone.
