Cleaning River Silt and Fixing Frost Heave in Grand Forks
Grand Forks sits on black gumbo. This soil is heavy. It holds water and refuses to drain. When the temperature drops to thirty below, that wet ground freezes solid. It expands with massive force. It pushes against the concrete foundations of the headstones. We see foot-thick concrete pads snapped in half by the frost pressure. This leaves monuments tipping over or sinking unevenly when the spring thaw turns the clay into soup.
The river is the other problem. High water leaves a residue on the lower stones in Memorial Park and Calvary. This isn't just mud; it is fine river silt. It packs into the engraving and dries hard. It bonds to the rough rock-pitched edges of the bases. Families searching for headstone cleaning services near me call us to dig their sunken markers out of the gumbo and to chip that hardened river cement out of the family names.
Digging Out Frost Heaves
The frost here is powerful. If a monument sits on clay, it will move. The ground pushes it up in winter and drops it in spring. The stone leans a little more every year.
We stop the movement by changing the base. We lift the stone. We excavate the black clay. We don't put it back. We fill the hole with crushed, angular rock. This gravel drains instantly. Water runs through it before it can freeze. If there is no ice under the stone, the ground can't heave it up. The marker stays flat.
Removing Hardened Flood Silt
River silt is microscopic. It gets into the pores of the granite. When it dries, it turns grey and hard. Scrubbing with a brush does nothing. The silt is harder than the bristles.
We clean it by re-hydrating the mud. We use a surfactant to loosen the bond. Then we pick the silt out of the letters with wooden tools. We work on one character at a time. It is the only way to get the contrast back without using sandblasters, which would ruin the polish.
Killing Valley Lichen
The humidity from the river and the dust from the potato fields feed lichen. It grows thick here. We see orange and green scabs covering the dates on older stones.
We kill it chemically. We soak the growth in a biocide. It dies and lets go of the rock. We rinse it away. This gets the stone clean without the risk of scratching it with steel scrapers.
Restoring Winter-Damaged Bronze
Grand Forks winters are brutal on metal. Snow sits on the bronze markers for five months. It eats the protective lacquer. The bronze turns green and chalky.
We restore them on-site. We strip the failed coating and the green corrosion. We sand the face to reveal bright bronze. We heat the metal with a torch to dry it completely. We spray a new industrial sealer on the hot plaque. It hardens immediately and keeps the metal dark.
Cleaning Polished Granite
The wind here carries grit. It impacts the face of the headstones. Over time, the polish looks dull and grey because it is covered in a layer of impacted dust.
We use a specialized cleaner to lift this film. We scrub the surface to pull the dust out of the stone's pores. We rinse it clean. The grey haze disappears, and the stone looks black and shiny again.
Repairing Mower Chips
The grass grows fast in the valley. Mowers run constantly. They hit the corners of the bases. We see chipped granite and black rubber streaks.
We wipe the rubber off with a solvent. For the chips, we use diamond files. We grind the sharp, broken edge into a smooth bevel. It looks intentional and finished. It also stops the mower blade from catching that same jagged spot again.
