What Does Foundation Drain Mean?

A foundation drain is defined as a drain that is installed at the foundation of a structure to prevent water from collecting around it. These drains are installed in the exterior of the foundation at the footing. Foundation drains are installed simultaneously with footing during the foundation phase of a structure. In cases where foundation drains have not been installed, it is possible to install them with the help of trenchless technology with minimum disruption to surface topography.


Trenchlesspedia Explains Foundation Drain

A properly installed foundation drain will prevent hydrostatic pressure from building and pushing water up via a capillary effect into the basement or the ground floor of a structure. During heavy rain and snow fall, water collects around the house and eventually the ground water level rises. Concrete is a porous substance and will allow water to seep through and causing extensive damage to property. Foundation drains consist of a pipe that runs around the foundation, a filter fabric and crushed stone set up to prevent soil from clogging the pores and entering the pipes, and a sloped drain pipe connecting the foundation drain to a storm water system. Replacing foundation drains by the conventional method would require digging up the side of the structure which can prove very expensive and time consuming. Trenchless technology can be used in such cases to install or replace such pipelines.
