                     Why Foundation Drainage Is Important and 
Some Ways It Can Be Implemented
  
Defining Foundation Drainage? 
Foundation drainage refers to a system or multiple systems 
that keep your foundation free of water. The system is 
installed on the exterior side of our structure’s foundation 
near its wall footing. A good drainage system should carry 
away rainwater away from your structure’s foundation, thus 
keeping it dry or only a little moist.  Constant pooling of 
water around your structure may eventually weaken the 
foundation leading to costly repairs. That’s why quickly 
taking care of drainage repairs in Oakland is so important. 
  
Different Ways Through Which you Can Install 
Your Foundation Drainage
Gutter drainage system 
French drains 
Footing drains 
Grading drainage 
  
Gutter Drainage System 
While some wind-driven rainfall may strike the side of your house and end up near 
its foundation, most of the runoff is from the roof. This is why the most common type 
of drainage is the gutter system. The gutters collect the water while downspouts 
drain it away from the foundation. You can add extenders if you are worried that the 
dow nspouts are draining the  rainwater too close. If possible, direct the water to a 
catch basin or a storm sewer. 
French Drains 
In this type of foundation drainage common in Oakland and the East Bay, a trench 
that slopes away from the house’s foundation is dug up. A perforated pipe is then 
placed on the trench, which is then filled with a porous material such as gravel. 
Stan ding water gets absorbe d by the gravel, gets into the perforated pipe, and is 
carried away from the foundation.
Footing Drains 
This is arguably the most effective foundation drainage system. It involves the 
installation of a pipe around your foundation’s perimeter on the same level as its 
footing. This ensures that any water that could have leaked through the footing is 
coll ected and drained away.  Footing drains work best if they are used alongside 
French drains. 
Grading Drainage 
This is a simple technique where the grading is reworked so that it slopes away from 
the structure. While it is simple, it involves quite a bit of work. Also, a contractor has 
to assess the right gradient for this type of drainage system to be effective.
