Drainage Issues with Negative Flow
This home had an unfortunate water drainage issue, which led to negative water flow, back up, and interior mold growth. A planter was built adjacent to the siding of the house. The planter was filled with soil and coming into direct contact with the siding. This created a damp environment and rotting of the siding. The continued dampness led to mold on the interior. Inside the planter, there was not adequate drainage installed and the plantings created an extensive root system that penetrated the underground pipes. The main catch basin was examined and discovered that roots were running through all the joints.
The trees, stumps, and root thatch were removed from the planter. The earth was removed 3-4 inches below the concrete patio elevation.
New Drainage Pipes with Positive Flow
With the installation of new drainage pipes, we created positive flow when setting the pipes in place (with writing facing up on the pipes for future reference). As we began our back hoeing process, we made sure we lifted one end of the pipe up and had positive flow.
We installed removable brass drains and tamped down and compacted all the trenches with soil after installing the drainage pipes. We tested the flow of water by running water at full force with a water hose into the inlet drainage pipe. The future downspout was extended into the drainage pipe. We’ve added drains in this planter along with landscape fabric to prevent weed growth and visible drain inlets.
The drainage was tested to make certain that the water was now moving at the same rate as it was flowing into the inlet. The farthest discharge outlet was observed to ensure the same flow. We noticed the water was flowing in at the same speed, but the HOA’s pipe was not flowing out well. We ordered a video camera inspection and inspected the HOA’s pipes.
Drainage Lessons Learned
A good lesson to remember is to never have soil up against the foundation interface. a trouble free drainage system requires three ingredients: quality materials, quality installation and bi-annual maintenance before and after the rainy season. Don’t wait until you have mold, mildew, and backup because your homeowner’s insurance won’t cover the expense.
