The number of homes built on poured foundations in the United States and Canada has increased significantly. Concrete block and poured foundations can crack, just like concrete blocks. The waterproofing industry used to recommend the use of drain tiles as a solution for leaking cracks. Basement waterproofing contractors have seen more foundation cracks over the years and have learned to appreciate the advantages of the low-pressure injection system.

Since the 1960's, epoxy has been used for pouring structures such as bridges, dams and highways. This technique was later adapted to basements by low-pressure injection of epoxy or polyurethane foam using a manual dispensing device. Crack injection allows homeowners to fix structural foundation cracks and leakages for thousands less than installing drain tiles.

Although drain tile is effective in diverting water from the floor and preventing it from building up, it is not the best solution. The homeowner may have to prepare for drain tile installation, which can prove to be costly. The end result is usually very costly.

Although crack injection is becoming more popular among waterproofers, some still remain skeptical of crack injection. Although drain tile is able to divert water from flooding basement floors, crack injection still allows water in basements. Indoor air quality can be affected if water seeps into basement.

Water seepage increases moisture and mold growth. However, soil gases, including radon, can enter basements through the continuing exposure of cracks. If the drain tile is an open-system, there may be a small gap around the cove, where the wall meets the floor. This allows soil gases to enter the basement. More than half of the air in the home comes from the crawl space and basement. The health of the home's inhabitants can be affected by exposure to mold, mildew, and other gases. This includes the development of allergies and asthma symptoms.

Drain tile has another disadvantage: it doesn't properly address foundation cracks. Cracks that are structurally related can be repaired by injection of epoxy or specially formulated foam polyurethane foam, in conjunction with carbon fiber staples. Staples provide a permanent solution for the crack by ensuring that any additional stress to the foundation is not transferred to the area being repaired.

Crack injection is not possible for foundations that are poured. Crack injection is not possible for cracked concrete blocks water leaks. The only options are complete exterior excavation or the installation drain tile.

For indoor air quality and drainage systems, waterproofers need to consider closed systems. Closed drainage systems will not only divert water from the basement floor but also prevent soil gases (including radon gas) from getting into the basement through the cove.
