Decks, Balconies & Roofs
 

Decks, balconies, and roofs are constantly exposed to the elements — from rainfall and UV rays to thermal movement and everyday wear.
Effective waterproofing protects these structures from water ingress, corrosion, and deterioration, preserving both appearance and integrity for years to come.

Decks

Decks are among the most challenging areas to protect due to their constant exposure and structural variations. Whether it’s an exposed podium deck, a buried roof garden, or a parking deck above a basement, each application demands precise design and flawless installation.

Our team considers every factor — from substrate type and drainage design to UV stability, fire protection, and natural weathering — to select the most suitable waterproofing system. The result is a durable, fully integrated solution designed to perform under changing conditions and heavy use.

Roofs

Flat Roofs

Flat Roofs

​Flat roofs remain one of the most practical and cost-effective waterproofing applications, particularly across commercial and multi-residential developments.

They require robust, seamless waterproofing membranes capable of resisting ponding water, UV exposure, and thermal stress.

Green Roofs

​​​​​​​​​​Green roofs bring aesthetic and environmental benefits while improving thermal performance and reducing surface water runoff.

These systems consist of multiple layers — including a waterproofing membrane, root barrier, drainage layer, and growing medium.

​​Pitched roofs demand a different waterproofing approach, focusing on underlay membranes, ventilation, and effective detailing around ridges and valleys.
We supply and install full pitched roof systems — from breathable underlays to durable tile and slate finishes

Pitched Roofs

A warm roof system positions the insulation layer above the structural deck and below the waterproofing layer, keeping the entire roof structure within the thermal envelope.

This prevents condensation and thermal bridging while improving energy efficiency.

Balconies

Modern Balconies

Balconies are fully exposed 24/7 and require systems that can withstand UV exposure, movement, and surface wear. Our waterproofing solutions are designed for both new-build and remedial projects, providing long-lasting protection and maintaining safe, slip-resistant surfaces.

Each system is tailored to the building’s design and usage, combining high-performance materials with expert installation. The result is a seamless waterproof barrier that prevents leaks, protects internal finishes, and preserves the structure for years to come.
