Basement waterproofing 101

Basement waterproofing usually refers to an interior drainage system.
The interior system is otherwise known as negative side waterproofing because this system controls sub-soil water rather than preventing it.
Interior basement waterproofing addresses the hydrostatic pressure of groundwater forcing its way through the basement walls.
Interior basement waterproofing systems can have many names such as; trench drain, drain tile or French drain.
Essentially it’s jack-hammering open the concrete floor to install a drainage and sump pump system.
Basement Waterproofing does not require a filter or sock

In 1859 Henry Flagg French wrote about his basement waterproofing drainage system in his book Farm Drainage.
It is still called a French drain 155 years later and is still the standard for basement waterproofing.
A French drain consists of a trench layered with stone, a pipe delivering the water to the sump pump, covered with stone and the floor re-cemented.
Nowhere in Mr. French's description of his drain did he mention a sock, landscape fabric or filter. Why?
What do all filters have in common? Think of your HVAC system or the air filter and oil filter on your car.
Eventually filters will become clogged by the particles they are filtering out. Filters have to be replaced from time to time.
If you have a sock around the pipe in your basement waterproofing system, how will you replace it when it gets clogged?
This would involve jack-hammering the floor again and re-doing the basement waterproofing system.
That is why you don't want a landscape fabric, filter or sock around the pipe of your basement waterproofing system.
