Balcony & sit-out

Balcony and sit-out waterproofing

A balcony is a small terrace with a big drop below it. Water that sits at the door line or at the railing base goes straight into the slab and appears on the ceiling of the flat downstairs.

You probably need this if…

  • Water standing near the balcony door after rain
  • Damp patch on the ceiling of the balcony below
  • Cracks where the railing posts are fixed into the slab
  • Efflorescence on the underside of the balcony slab
Why it happens

What causes it

The same wet patch can come from different places, and each one needs a different fix. This is what we look for on site.

  • 01

    No slope towards the outlet

    The balcony floor is often flat or, worse, slopes towards the door. Water has nowhere to go.

  • 02

    Railing fixing points

    Every post drilled into the slab is a hole through the waterproofing. If not sealed, each one leaks.

  • 03

    Door threshold level

    When the balcony floor is at the same level as the room, water crosses the threshold and enters the room.

  • 04

    Blocked or undersized outlet

    A single small outlet, half blocked with leaves and dust, keeps the water standing.

How we do it

Our balcony & sit-out process

Step by step, in this order. Nothing is skipped to finish a day early.

  1. 01

    Check the slope and the outlet

    We check where water actually stands, clear the outlet and plan the slope correction needed.

  2. 02

    Seal the fixing points

    Railing bases and any other penetration through the slab are cut, packed and sealed.

  3. 03

    Cove and treat the junctions

    The floor-to-wall and floor-to-parapet junctions are coved and the door line is treated.

  4. 04

    Coat and finish

    Waterproof coats are applied over the corrected surface and finished, ready for tiles or left as a protective top coat.

What is included

  • Slope correction so water reaches the outlet
  • Sealing of railing fixings and other penetrations
  • Coving at wall junctions and the door threshold
  • Waterproof coating, with a top coat if the balcony stays open
  • Water test before handover
