How Do I Waterproof Correctly To Avoid Future Leaks?
Cement Sheeting must be laid in half bond or brick pattern.
Install a heavy-duty PVC liner directly to the substrate without sticking it down; it will remain loose and will sit on top of either the cement sheeting or concrete slab. Use self-adhesive flashing or similar material to adhere the loose PVC liner to the verticals or plumbing openings.
Apply your screed with a fall; do not use off white cement as this is a quick-drying process that will inadvertently lead to efflorescence.
Waterproof on top of the screed once cured, and dry wrap waterproofing down to meet up with the puddle flanges.
Lay tiles with falls to the waste, so water does not pond on the balcony.
Only place pots on the balcony if they have adequate drainage or feet on them, so water does not pool.
How Do I Waterproof Planter Boxes?
Waterproof with a UV stable waterproofing membrane.
When planting, use pots with feet on them; this will ensure the pot will sit off the planter base, allowing for adequate drainage and preventing weeds from breaking down the membrane.
