Sinkhole Repair / Erosion Control

Majer’s Diving & Salvage offers complete sinkhole repair solutions in Hilton Head, the Lowcountry and beyond.  Our proven systems can repair sinkholes at seawalls, retaining walls, bulkheads and in roads caused by underground pipes or erosion.

First, we identify areas where soil/sand are eroding by injecting non­hazardous dye into the sinkhole and observe where it exits. Once leaking areas are identified, repairs are made using either epoxy or expanding poly­grout which both work underwater and is environmentally safe. Once repairs have cured, we pressure inject expandable poly­grout into the sinkhole area. This grout is a soil stabilizer and mixes with the existing soil and creates a waterproof, lightweight mass which fills the void as it expands. This system plugs leaks from both the water side and the land side resulting in a 2 tier defense against future leakage and erosion. 

Our teams have worked for some familiar clients such as:

  • Windmill Harbor Marina
  • Town of Hilton Head Island
  • Long Cove Club
  • Shipyard Plantation
  • Palmetto Bay Club
