Sill Diagrams

Sill (Exterior Slope) components include…

• Exterior slope for water runoff to keep facade wall dry

• Lower drip groove to catch the water instead of letting it run back into the wall

• Elastomeric sealant for Elastomeric sealant is a highly flexible, rubber-like material used to bridge gaps and create a waterproof barrier in areas that experience frequent expansion and contraction

• If the groove is not present rainwater travels unde the slab and damages the wall “seepage“

• A drip groove or drip mould stops rainwater before it travels back under the slab and damages your wall.
