The proper routing of water is a critical issue for protecting against leakage and maintaining the integrity of a home's foundation. Proper drainage is often necessary, but it can entail problems.
Disadvantages of drainage include differences regarding the type of system or the materials used. For example, the disadvantage of clay will not be the same as drawbacks applying to a French drain-system. The inherent benefits of a material or system may outweigh the disadvantages.
Some Common Disadvantages
French drains are notorious for soil or mud build-up. This may lead to drainage defects that channel water into your home. For clay, normal amounts of pressure might cause the drainage system to deteriorate. Different types of drainage - and how it is installed -- may limit your landscaping choices.
Maintenance is a primary disadvantage of drainage. This is especially true of roof gutters, which might collect enough leaves and debris to warrant professional clean-up. Any discussion of disadvantages must include mention of the prices of maintenance.
