FOUNDATION CRACK REPAIR IN LONG ISLAND AND QUEENS, NY

Basement foundation walls are typically fabricated from concrete. All professionals agree that it is the nature of concrete to crack for many reasons and it is hard to avoid, especially in a Long Island, New York climate. Normally a crack in a foundation wall is not considered a defect and is no more than a blemish in most cases. The most common problem associated with foundation wall cracks is water penetration. These cracks create openings into the basement that water could pass through.

In addition to exterior foundation waterproofing and sub floor drainage systems, Boccia Inc. offers foundation wall crack injection systems that will inhibit water from passing through a wall crack. These systems are designed and intended to close the void that the crack has created so it is impervious to water penetration. The installation process of a crack injection system is as follows.

The area adjacent to both sides of the crack on the interior side of the foundation wall is cleaned and prepared so previously installed coatings and paints are removed and a sound substrate is provided. Ports are then installed over the crack spaced approximately one foot from each other with an epoxy adhesive. A two part specifically formulated epoxy is troweled over the completely prepared area of foundation wall bridging over the crack that should be centrally located.

After allowing the epoxy to set, a hose is attached to the installed ports from a pressure producing instrument into which urethane material is installed. Under pressure the urethane is injected through the hose and into the port and fills the foundation wall crack from the bottom up. As the urethane material fills the crack and commences to flow from the adjacent ports, the hose is removed and capped. This process is continued until all the ports are filled and completed.

The urethane material swells in the foundation crack locking it in place.  This results in a crack that is enclosed and sealed so water cannot pass through it in the future.
