The gutter system on your home is designed to capture the rainwater from the roof and carry it away from the foundation of the home. Some areas have a significant amount of yearly rainfall and require a bit more effort when installing the downspout and outflow sections of the gutter to ensure the water does not build up next to the foundation. Burying the downspout is an effective way to carry away this excess. Does this Spark an idea?
Instructions
1. Dig a sloping trench from your downspout to a point 8 feet away. The end of the trench next to the house will be 18 inches deep and the far end will be 30 inches deep. Dig the trench 15 inches wide down the entire length. Use your tape measure to periodically check of the width and depth of the trench.
2. Unroll your landscaping tarp beside the trench. Cut the tarp with your razor knife so that you have a tarp that is 1 foot longer than your trench. Slice down the length of the tarp so that you have two pieces 2 feet wide each. Set one aside for a future project. Fold the other in half so that it is 1 foot wide and lay it into the trench with the extra foot laying up the side of the house in the trench.
3. Cover the bottom of the sloping trench with gravel. Carry the gravel to the trench with your wheelbarrow and spread it with your shovel. Be careful not to displace the tarp in the trench when placing the gravel.
4. Place the French drain onto the gravel in the trench. Turn the drain so that the slots in the side are face down. Pull the end of the drain onto the end of the outflow of your downspout. Cover the drain with 3 inches of gravel down the entire length of the pipe. Add gravel to the end of the trench, past the end of the drain, so that it is level with the gravel covering the drain.
5. Cover the gravel with the soil from the original digging. Pile it 3 to 4 inches higher than the surrounding ground level. Walk on the new soil to pack it down firmly. Carry off the remaining soil and let the trench settle for a week to 10 days. Add more soil to any areas where the new soil settles to a level lower than the surrounding ground.
