The common tie rod hole problem has been an issue for homeowners causing flooded basements, lost items and costly repairs. These leaks are often incorrectly diagnosed as a failed foundation drain tile system, or an unexplained leak source that results in high repair costs for the consumer.
The most advanced repair method for stopping this type of basement leak is the TRX® Swell Plug. The only product of its kind, this patented plug has been used since 1997 by thousands of customers nationwide.
The TRX® Swell Plug uses water-activated materials so that it can co-exist in wet environments more effectively than conventional bonding materials such as hydraulic cement products, epoxies, or caulking. When a TRX® Swell Plug is exposed to moisture the polyurethane body is activated, expanding to seal the tie rod hole and stopping the leak immediately.
When a foundation contractor erects the form of your basement, tie rods are fastened to support the shuttering (walls) which holds the weight and the form of the foundation wall. Once the cement is poured, these forms are left a few days for curing. Next, the tie rods are removed allowing the forms to be dismantled and your foundation is complete.
The walls now have holes where the tie rods were that are approximately 5/8 inches in diameter, usually in two rows separated every 18 inches throughout the entire basement. In this type of conventional forming system, the tie rods are not left in the wall. The only time supporting wall forming ties are left in the wall is when a contractor uses a wall forming system that utilizes snap ties.
