Foundation Drain Installation questions, answered by experts

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.

You will need to fix a saturated leach field if you have a problem with the septic system that is causing improper drainage. If rainwater is pooling over the top of the leach field because of low spots at ground level, repairs are necessary. Options for fixing a saturated leach field include regrading the soil, emptying the septic tank, using a larger septic tank, or replacing the leach field.

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.

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.

The process is different for each type of drainage system. But no matter your drainage system type, you’ll have to start by digging a hole or trench. To install an effective French drain, for example, you’ll need to dig a trench, line it with filter fabric, pour gravel inside, hook up pipe connections, set the pipe, and cover it with gravel.

You can use shovels or rent a trencher, depending on the size of the trench or hole you’re digging. You generally don’t need a permit from the city to install a drainage system on your own property, but if the work involves changing a structure or electrical work, contact your municipality to check the requirements.
