Small holes often require only filling with clean sand or soil. Mark and secure the hole and keep children and pets away. If the hole is directly impacting a house, and sinking, sagging, or cracking walls are apparent, stay out of the dwelling.
Less commonly, sinkholes may be caused by broken water pipes, cisterns or disturbance of the soil (by digging, drilling, soil removal), vibrations caused by traffic or mine blasting. Underground water can form one as well.
Call us immediately if you discover you have a sinkhole.
