Sinkholes that occur near outside walls usually develop because the soil along the structure was poorly compacted. They can also be caused by buried or rotting debris or tree stumps that are not removed, or by poorly compacted soil around buried drainage pipes or sewer lines. Over several years, the debris decomposes and the soil settles and causes a depression or hole.
Daniel Dean has corrected many sinkholes with lasting solutions. We determine the severity of the problem and clean out the loose debris. Then compact layers of select fill, and recover the top with grass of organic top soil.
