Drain Only Weep Tubes

leaky building

Weep tubes for masonry weep holes.  Weep holes are the gaps left between some bricks in external masonry walls.  They serve 2 purpose:

Ventilation of the internal wall cavity – Without ventilation, mildew, dry rot and damp reduce the life of the internal wall studs and other building materials within the cavity. Inadequate ventilation is the main cause of “Leaky Building Syndrome”.

Drainage – Water that enters the cavity due to capillary action, condensation, damage, or accidental flooding needs to escape somewhere.

One end of the tube is bent in a downward position to prevent wind driven rain from being forced back into the tube.  This also prevents water running down the wall from re-entering the building. They will not fill with sediment because the fabric filters it, but allows the water to drain.
