the structure below being very well maintained with adequate grading the
basement concrete foundation wall separated (cracked), likely due to
concrete shrinkage and ground settlement thereby allowing ground soil
water to enter. This crack traveled from the concrete floor slab up
to the bottom corner of the basement window. Shrinkage cracks can
usually be detected from the outside as seen below at the centre.
are photographs of other shrinkage cracks in poured concrete foundation
walls. The Penetron System was utilized to
remediate the ground soil water infiltration problem in each case.
rods also known as "tie pins" are used to hold forms together
during the construction of poured concrete foundation walls when the
concrete is being poured. Occasionally these tie pin holes
leak. The tie pin holes and adjacent areas in the photographs below
have been treated with the PENETRON waterproofing system.
standing rain water pooled on these porches and leaked into the cold
storage rooms of the basements through the weeping holes between the
brick and the through holes in the damaged poly flashing behind the
bricks. The PENETRON waterproofing system solved this problem from the
damaged poly flashing can be seen that allowed wind driven rain to pass
through the weeping holes of a brick wall. The mortar appears to
have protruded through the ploy flashing resulting in water running down
the concrete foundation wall onto the concrete floor slab.
