Driveway Void Repair in Benton, AR: Eliminating Erosion and Mole Damage Before Structural Failure
Sunken Driveway and Soil Erosion Threatening Structural Integrity
A homeowner in Benton, AR experienced significant driveway instability caused by soil erosion and mole tunneling beneath the slab, creating voids and sections of sinking concrete. The issue posed a real risk to the driveway’s structural integrity and long-term durability. A comprehensive Concrete Protection System (CPS), including PolyLevel lifting and NexusPro joint sealing, was successfully installed to stabilize, lift, and protect the driveway from further damage.
Identifying the Problem: Driveway Voids from Erosion and Mole Activity
Pat G. noticed worsening conditions in his driveway, where moles had tunneled beneath the concrete and water erosion had washed away supporting soil. This combination created hidden voids and led to visible sinking, especially near the carport where the slab had dropped several inches. Additionally, poorly managed water runoff from two downspouts contributed to ongoing soil displacement. The presence of wooden control joints further weakened the structure, increasing the risk of cracking and long-term deterioration. Left unaddressed, these issues could have resulted in costly replacement instead of repair.
Proven Solution: PolyLevel Injection and Concrete Protection System (CPS)
To restore and stabilize the driveway, a two-part Concrete Protection System was implemented. PolyLevel foam injection was used to fill voids beneath the slab and lift sunken sections back toward their original position, successfully correcting two major problem areas. Given the driveway’s relatively thin 4-inch slab, precision application—including a free-shot technique—was critical to achieving lift without causing additional stress. Cracks and joints were then sealed using NexusPro, a durable, flexible sealant designed to prevent water intrusion and future erosion. Wooden control joints were removed as part of the process to improve long-term performance.
Importance of Water Management and Long-Term Protection
Beyond structural repair, addressing the root cause of the problem—water intrusion—was essential. Buried downspout extensions were installed to redirect water away from the driveway, significantly reducing the risk of future erosion. Combined with sealing and stabilization, this approach ensured a longer-lasting repair and helped protect the homeowner’s investment. Proper water management and void filling are critical components in preventing recurring driveway settlement issues.
