One
Wythe walls need to weep!
Split-Face Masonry Units
with integral water repellent have the capacity to pool water
in the cores of the block.
This wall was left open
at the top of the wall. The salt buildup is due to the
water leaching slowly and depositing heavy salt on the
surface. |
|
| This
wall was full of water. Drilling a hole at the bottom of
the faceshell of this block clearly shows the water draining.
We have the solution!! |
