The Manthorpe Diamond Cavity Wall Weep Vent is an essential component for bricklayers and building contractors who require a professional-grade solution for cavity wall drainage. Its primary benefit is the innovative diamond-shaped profile that promotes natural water flow and self-cleaning, effectively preventing blockage from debris. While it offers superior drainage performance, installers should be aware that it requires careful placement within the perpend joint during the initial masonry phase to ensure a perfectly flush finish.

Yes, the 65mm height is designed to correspond perfectly with standard UK brickwork perpend joints.
The 4mm opening is specifically sized to prevent large insects from entering while maintaining high water drainage capacity.
Installation frequency should always follow local building regulations and project specifications for cavity wall drainage.
While the plastic is durable, ensure that any paint used does not clog the drainage aperture.
Yes, the diamond-shaped profile is designed to encourage self-cleaning by accelerating water flow to flush out debris.
Check that the mortar joint depth is sufficient and that no internal debris is pushing the vent outward.
Verify that the weep is not blocked by mortar droppings inside the cavity and that the DPC is correctly positioned.
Installation should occur during the construction of the outer leaf of the cavity wall. Position the vent within the vertical perpend joint of the brickwork, ensuring the front face is flush with the brick surface. The integrated ribs are designed to bite into the mortar, so avoid over-troweling the mortar immediately surrounding the vent to maintain its grip. Periodically inspect the vents during site handover to ensure no excess mortar has blocked the 4mm opening. No special tools are required, though a standard pointing trowel is recommended to finish the mortar around the vent cleanly.
