3 Considerations For Your Exterior Drain Tile When Adding To Your Foundation

If you are building an extension to your home or putting in a patio or driveway, you will likely be digging up your drain tile to access your foundation and add to it. This creates the perfect opportunity to do some maintenance on your drain tile and replace any worn or old parts. 

Saving Materials 

Most of the materials from your exterior drain tile can be saved and placed in a new location after you have extended your foundation. However, to do this you will have to dig up your drain tile before you begin more extensive excavation for your project. Saving gravel for future use is as simple as using a backhoe to dig up the gravel and place it in a safe area of your yard.

Saving the pipe and cloth wrapping for your drain tile takes a bit more finesse. You may have to remove the first layers of rock with a backhoe and, once you get close to the pipes, dig by hand to prevent any damage. You will have to decide if the extra time and energy is worth saving these pieces or if you will want to replace them when you extend your exterior drain tile. You may want to purchase new fabric for filtering out sediment but reuse your old piping if it is not damaged or showing signs of age. 

Updating Your Whole System 

Major construction on your home provides an ideal opportunity to update your entire drain tile system. You may want to do this if your system is old, constructed with clay tiles or pipes, or having issues with clogging. You can utilize the construction equipment (or pay your contractor) to dig out your drain tile around your entire home instead of just around the area where you are building. 

If you are rebuilding the entire drain tile, you should take the opportunity to look for cracks and signs of wear on your foundation and apply a new layer of waterproofing directly to your foundation. You should then replace your drain tile system with a modern PVC system, being sure to include regular surface outlets for maintenance access. 

Even if you are replacing your entire system, your gravel should still be reusable. You may want to rinse the gravel before replacing it over your new drain pipe. 

Updating Part of Your System 

A more cost efficient solution is to simply replace the drain tile in the area where you are adding an extension onto your home as opposed to digging out your entire system. Whether you have a clay or PVC pipe, it should be easy to detach it from the rest of your system. You should then take this opportunity to thoroughly flush your system with pressurized water or air. 

If you will be connecting a new PVC pipe to old clay tiles, you can simply lay the pipe next to the old tiles or piping, ideally having the ends touch. If you will be attaching new PVC pipe to old PVC, you will want to thoroughly clean the old pipe and apply an appropriate amount of adhesive before attaching the new pipe. 

If your old drain system has no maintenance spouts, you will want to take this opportunity to add one or two vertical sections of pipe to make cleaning and maintenance easier in the future. However, you may want to avoid adding the maintenance spout near the spot where the new system is connecting to the old system, as this can be a weak spot, depending on your old system. 

Taking care of your drain tile can help extend the life of your foundation, making leaks and cracks less likely, so you should use major construction as an opportunity to check your drain tile and repair it as necessary.
