Deck & Balconies

This is an area of speciality for Arti Structural Waterproofing. We have installed many deck and balcony waterproof systems from multiple balconies in large apartment complexes to single balconies within residential homes. Each balcony or deck is treated with the same meticulous design and planning before installation to create the perfect watertight outdoor space.

Deck Waterproofing

Deck and Podium Deck waterproofing is the term used for:

– Above ground decks that are exposed to all the weather elements.
– Decks that sit on top of a buried roof in subterranean rooms or on top of a basement roof under the garden/car park or top level substrate.

As decks can be subject to varying elements both in the earth or above ground level then product selection, great design and perfect installation are required. Your designer will consider the structure type to make sure the product selection is suitable and able to be perfectly applied to the surface. They will also consider the elements – and not just water – UV protection, fire protection and natural weathering also must be considered as Decks are subject to varying environments from above and below.

Arti is here to create the perfect solution with the best and most suitable products for your project.

Balconies Waterproofing

Balconies are usually located above ground and on the side of buildings. These spaces allow our clients to access outside space and are subject to natural elements 24/7. Therefore balcony waterproofing products must also be UV resistant, non-slip and have fire protection. Our tried and tested balcony waterproofing solutions are tailor-made specifically for your building.

We have the experience and expertise to deliver fast new build or remedial waterproofing solutions for your balconies. Our team are experts in this field of waterproofing and we pride ourselves on delivering the right system correctly installed first time.
