Building protection solutions

The problem

The roof takes direct sun, rain and ponding water. Most leaks start at parapets, drains and penetrations long before they show on the ceiling below.

• Roof leaks
• Membrane blistering
• PU bubbling

The problem

Facades take wind-driven rain, heat and carbonation. Damage usually starts at cracks, cladding joints and around openings.

• Concrete cracks
• Efflorescence

The problem

A balcony is a small exposed roof over occupied space. A weak detail at the door threshold or the edge sends water indoors or into the ceiling below.

The problem

In bathrooms and kitchens water works under the tiles every day. Leaks usually start at corners, floor drains, pipe penetrations and the shower zone.

The problem

Basement walls and slabs work against groundwater pressure and soil moisture. Leaks appear at construction joints, cracks and through the walls.

• Basement seepage
• Negative-side moisture
• Efflorescence

The problem

A tank is loaded from both sides: stored water inside and soil moisture outside, and the layer in contact with drinking water must be approved for that use.

• Tank leaks

The problem

Parking floors take tyres, oil and daily abrasion. The concrete needs a traffic-resistant surface that keeps water and salts out of the slab.

• Epoxy peeling
• Concrete cracks

The problem

A pool holds water permanently, under pressure and with treatment chemicals. Leaks start at construction joints and pipe penetrations before they show in the spaces below.

The problem

Foundations are waterproofed once, before the pour and the backfill, and are out of reach afterwards. They need one continuous layer under and around the raft.

• Basement seepage

The problem

Planters stay wet all the time, and roots and fertilisers attack the waterproofing. They need a root-resistant layer and proper drainage of excess water.

The problem

An expansion joint moves with temperature and loads, and rigid materials crack across it. It needs a flexible system that takes the movement and stays watertight.

• Expansion joint failure

The problem

The lift pit is the lowest point of the building and the first place groundwater reaches. A leak there harms the equipment and is hard to fix later.

• Negative-side moisture
• Basement seepage
