Leaking balconies at home

Stop the leak before it reaches the steel

Balcony leaks get worse with every storm. Water gets past a failed membrane, upstand, or drain, stains the ceiling below, and can work its way into the slab edge.

We find where the water is getting in using flood testing, thermal imaging, and dye testing, so the repair targets the cause. Then the same team restores the waterproofing and repairs the concrete.

When to call

Signs your balcony is leaking

Stains or drips on the ceiling below

Usually the first sign the balcony membrane above has failed.

Water coming in at the door

Often a membrane upstand or threshold problem.

Cracked or drummy tiles

Loose tiles and cracked grout let water get under the membrane.

Water pooling after rain

Poor falls hold water against the membrane and the joints.

Rust stains or cracks at the slab edge

Water reaching the steel causes concrete cancer.

Damp walls below the balcony

Water is travelling through the slab or the wall junction.

Not sure where the water is coming from?

Flood testing, thermal imaging, and dye testing find where the water is getting in.

Repairs

What we repair

Balcony waterproofing

Polyurethane liquid membranes follow upstands, drains, and penetrations without laps or seams.

Best for: Balconies, courtyards, and roof decks

Concrete cancer and slab edges

Damaged concrete removed, the reinforcement treated, and the section rebuilt.

Best for: Slab edges and balcony undersides

Planter boxes

Planter box and terrace waterproofing, so soil and water stay where they belong.

Best for: Planters and terraces

Leaking cracks

Polyurethane injection reacts with water and expands to seal cracks, with very little disruption.

Best for: Cracks in slabs and walls

Before and after
