Cracks

Cracks are a natural effect of concrete as it goes thru the drying phase.  Concrete actually shrinks as it dries leaving it no other choice but to crack.  You may find a crack in the middle of a wall or off the corner of a window or beam notch.  No matter where it stems from there is a chance of this crack leaking now or sometime in the future.  Heck, I’ve seen cracks that haven’t had a single drop of water flow through it but if you have one that is damp we highly recommend you get it repaired.

 

Rod Holes

Rod holes are just that, holes that were made by a 5/8″ rod that was used to hold the steel forms together when your foundation was originally poured.  Once the concrete cures these forms are disassembled and by doing so the removal of the rod that passes through the foundation takes place.  This actually leaves a hole straight thru your foundation which in most cases is filled on either side with a small ball of hydraulic cement.  Filling the hole in this manner leaves an open cavity in the middle of the foundation.  Think about that for a minute, there’s a hollow spot in the middle of your foundation blocked only by a small amount of hydraulic cement…what do you think is going to happen in the years to come if this procedure is not administered properly…that’s right, the hydraulic cement has a chance to break down and allow water to run past it right into your basement.

 

Snap Ties

Snap ties are small steel rods that are used to tie or hold the concrete form together while building your foundation.  Same technique used when using 5/8″ rod except the metal gets left inside the wall so there is no void.  But here’s the thing, after so many years of being exposed to damp conditions what happens to steel?  You guessed it, it rusts!  And when it rusts it actually breaks down and becomes less likely to keep that hole filled.  When this happens you start seeing signs of water seeping on the inside of the foundation wall which leads to wet floors and mould.

 

Window Well Drainage Problems

Window Wells are prone to leaking for a variety of reasons and usually with the same result – water flowing thru or under your window and down your wall like a waterfall. Top 3 reasons for window wells overflowing are:

  1. The well is filled with soil rather than with gravel and has become too dense (compacted) to drain properly
  2. There is no drain pipe located in the well leading down to the weeping system
  3. Drain tile or weeping tile is blocked and is no longer working

 

Floor & Wall Joints

Floor & wall joints are the areas where your foundation meets a concrete floor.  Floor and wall joints are another area that moisture can creep through and also one of the harder ones to control.  This type of situation requires the relief of hydrostatic pressure and the expelling of excess water.

 

Blocked or Collapsed Weeping Tile

weeping tile causes leaking basements in Ancaster and HamiltonBlocked or collapsed weeping tile can also lead to a foundation leak and water in the basement.

If the system is not working properly there is a tendency for the water to become “backed up” so to speak and sit against your foundation wall for a longer period of time that normal.  This can cause hydrostatic pressure to build up which in turn forces pressurized water to enter into voids and cavities it would not typically do.  This problem can creep up very slowly or quite abruptly depending on how the weeping system has become damaged or blocked.

 

Cracked Concrete Floors

Cracked concrete floors and floor drains can also be an area that allows moisture to come into your basement.  If your home is situated where water veins run rampant or where the water table is higher than normal you may experience leakage.  These types of situations can be tricky to fix and would require a site visit to determine the proper fix as there are more than one that could be valid.  In order to determine the proper fix I would suggest we come and visit with you to investigate your unique situation.  Click here or call us at 289-880-7988 to book an appointment.
