Weep holes and the two jobs they do

In short: No weep hole found in Leppington brickwork, recorded twice.

The drainage job

Every cavity wall admits some water. They give that water a way out and let the cavity breathe.

The clear gap between the weep holes and the ground is the zone where termite activity would have to become visible.

No weep hole found in runs of Leppington brickwork, on separate jobs at lock-up.

Water held against the frame behind the brick: slow, hidden and expensive.

Weep holes can be formed retrospectively and levels can be cut back. Both are ordinary trade work.

Questions Leppington owners ask about this

How many should there be?

Spaced at intervals along the base of the cavity and above openings. Where a whole run lacks them, the report records it.

Is this classed as a defect or as maintenance?

For new work it breaches the Code and the tolerances guide, which puts it on the handover list.

Has it any bearing on the pest side?

Directly. Losing the inspection zone is among the more consequential conducive conditions.

Is it common?

Common enough that we check for it specifically at lock-up, fixing and handover here.
