Older homes have concrete tiles;
newer homes use perforated plastic
pipe. Interior tiles receive water
from exterior drain tiles via
bleeders through the footings.
Interior tiles route the water to a
sump pump. To keep water out of the
rest of the basement, a thin coating
of tar or damp proofing is applied
to the outside of the foundation
when the house is built. Block
basement walls are “backplastered“
with a thin concrete coating on the
outside, under the damp proofing.
If you have
poor surface drainage or problems with
gutters and downspouts, you are inviting
rainwater into your basement. Drainage
systems are not designed to handle excessive
surface water. If water floods around your
basement, water will come in.
Your house may
have a sump pump. A sump pump is designed to
collect the water from your basement drain
tile system. Water can back up from this
sump pump if the electrical power goes out,
the flow is too great, the discharge is
blocked, or the pump malfunctions.
This storm water may overflow the sump pump,
run down the floor drain into the sanitary
sewer, and/or flood your basement.
