Cinder Block Walls

Cinder block walls pose a unique problem.  Each block typically contains 2 cells.  As pressure builds, water can enter these cells and if pressure becomes to great, penetration can happen at any of the seams in between each block.  When waterproofing cinder blocks, weep holes must be drilled in each cell to allow for drainage which is diverted into a sub-floor system to allow for a dry, worry free basement.

What Is A Basement Waterproofing System

A basement waterproofing system Keeps water from entering your basement.  There are four components of a typical system:
  1. Interior drain tile
  2. protection from future wall cracks
  3. sump basin
  4. sump pump
When these components are installed properly, a guarantee will be given that no ground water will pass across your basement floor for any reason.



Exterior French Drain

We have installed exterior french drains but in most cases I do not recommend them.  These drains are typically a drain tile that is in the ground roughly 8 - 10 inches below the surface area surrounded by crashed stone.  This is an alternative to gutters on a house and may reduce the amount of water building up around your foundation. They will NOT STOP hydrostatic pressure.  Also, during the times you need them most (ground thawing and spring rains) the ground is still partially frozen limiting their effectiveness.


Interior vs Exterior Perimeter Drainage

It all depends on who you ask.  If you ask a landscaper or construction company, they would tend to lean heavily toward exterior. A professional basement waterproofing company would be just the opposite.  Here are some pro's and con's for each.  The word "typical" will be used a lot since variations occur depending on circumstances.

  1. Cost - Exterior drainage must be placed below basement floor level to be effective.  In most cases it is 6 or more feet below outside grade which means they are bringing in a backhoe.  Exterior costs typically double that of internal systems. Residual costs also need be kept in mind (ie. replacing decks, shrubbery and lawn).
  2. Damage - Exterior drainage must be close to the foundation of the house. Typically this means loss of shrubs, plants, patios, decks and anything else not associated with foundation of the house.  Internal systems open the concrete floor roughly 6 - 8 inches wide around the full perimeter of the basement and must be placed right next to the concrete walls.  If you have a finished basement this typically means removing roughly 4 feet up on the walls in the area being worked on.  Do not forget to factor these costs to those that apply with the method being used.  These residual costs to replace these items will drive up the initial estimate.
  3. Clogging - Both systems can clog.  Not many companies will tell you that. In both instances the system being installed is surrounded by crushed stone which filters out a majority of sand and sediment from entering the pipe.  Over time that sediment can build to a point which closes off the flow of water through the pipe.  Most interior systems prepare for this by installing some type of access into the system so it can be flushed.  Exterior systems have additional vulnerabilities.  As these systems are back filled, they can be crushed by the heavy equipment as well as tree roots grow toward water and can strangle or infiltrate the pipe.
  4. Warranty - Both system installers will warranty their work if they are a reputable company, at least for a period of time.  Only a reputable basement waterproofing company will warranty their system for the life of the building.
