Sun Balcony – Construction, Waterproofing & Finish

Building a sun balcony: slopes and waterproofing, durable outdoor flooring, railings and roofing, and a finish that lasts.

A sun balcony is an extension of the home into the open air – a place for a seating corner, a meal or greenery. Because it is exposed to sun, rain and temperature swings, a balcony demands especially careful engineering, led by waterproofing and slopes.

Waterproofing and slopes: the critical base

Water is the balcony’s number-one enemy. A correct slope toward the drain, multi-layer waterproofing of the surface and the wall junction, and proper treatment of railings and drains prevent moisture reaching the rooms below. This is a stage with no compromises.

Outdoor flooring and cladding

Outdoor flooring must resist slipping, UV and temperature changes. Outdoor porcelain, natural stone or synthetic decking are popular choices. Joints and adhesive must suit outdoor conditions. More on flooring ›

Railings, roofing and finish

A safe, code-compliant railing, roofing or a pergola for shade, and waterproof lighting turn a balcony into a usable space at any hour. Correct finishing of the small details keeps the balcony beautiful and safe for years.
