Foundation Drain Installation questions, answered by experts

Leach lines are commonly made of PVC pipe, and they’re placed into trenches filled with gravel and sand, which help treat the wastewater. The PVC pipes are perforated, or drilled with small holes, so the wastewater can drain out of the pipes and into the surrounding material, which eventually leads to the aquifer.

Structural components—like the roof, foundation, walls, windows, and floors—should be addressed first thing when renovating a historic home. It may be appealing to start with more visible cosmetic issues, but structural problems are often the most time-consuming and costly, and dealing with them first can save you some big headaches down the road.

The pipe size for French drains depends on whether the area collects large amounts of water and experiences heavy rainfall. Typically, a 4-inch perforated pipe is used for French drains. However, for heavily saturated areas, you may want to use a larger size, such as a 6-inch or 8-inch pipe. Consult your French drain installer for best results.

Installation typically takes 3-7 days, depending on the system and site conditions.

Your homeowners insurance can cover slab leak repairs, but it really depends on your policy. Some homeowners insurance policies only cover slab leaks caused by natural disasters, while other plans are more comprehensive. You might also want to check your home warranty plan to see if they'll cover the cost of the repairs if one of your appliances caused the leak.
