Profile: ITG Basement Systems specializes in basement waterproofing, crawl space moisture control, and foundation repair services. Our French drain systems are installed with an 1 inch gap at the edge of the floor. These gaps can collect dirt and debris from the floor. Foundation piering is usually designed with a rugged steel pier and bracket. The bracket is designed to connect the pier to the foundation footing; while the pier itself extends downwards to strong supporting soils. These piers can perform effectively in most soil conditions. Foundation piers are provided in two forms; helical piers and push piers.
