Interior Waterproofing in Denver, COAny time a structure is built at or below ground level, basement drainage techniques are needed to keep the structure from developing several moisture related issues. Interior drainage is especially important if the water table is likely to be raised by built up groundwater. As the water table gets higher and higher, the hydrostatic pressure in the soil increases. This increased pressure pushes against the foundation walls and floor, causing them to shift and crack. These cracks create an entry point for water, opening the door for basement seepage and various other moisture related issues. Interior drainage systems can help reduce these problems by removing the water from the basement and carrying it away from the foundation.

Components of an Interior Drainage System

There are several different components that must be installed to ensure that your interior waterproofing system functions correctly. The most important parts of this system include:

  • Water Channels
  • Drain Pipes
  • Sump Pit and Lid
  • Sump Pump System
  • Vapor Barrier

The first part of the drainage system, the water channels, are installed along the bottom of the foundation walls to catch drips from cracks in the walls. These water channels also collect water that has seeped through the porous concrete of the foundation walls. The water channels then carry the water to the sump pit, where it is stored until it can be removed.

The next component, the drain pipes, are perforated drain pipes that are installed on the inside perimeter of the footings. Because they are installed below the footings, the pipes are able to drain the water to a lower level. This drain pipe system then dumps the water into the sump pit.

Sump pits, or basins are where all of the water collected in the interior drainage system is stored. Once the water in this pit reaches a certain level, it is pumped out by the sump pump. The sump pit is usually placed under the lowest part of the floor to provide the most efficient and effective draining. The ECP (Earth Contact Products) sump pumps used by Rapid are sealed with a lid to keep water and harmful soil gases well contained.

The sump pump turns on automatically once the water in the sump pit reaches a certain level. The pump then proceeds to pump the water out and away from the basement through a discharge pipe. Most sump pump systems are also equipped with a battery backup sump pump to keep them running even when the power goes out, or when the primary sump pump cannot keep up with the amount of water coming in.

Another part of interior drainage systems is the vapor barrier. This is a waterproof material, such as foil or plastic sheeting that is sometimes installed along the walls of a basement or crawlspace to seal out water and prevent basement wall seepage and leakage through cracks.
