Commercial Waterproofing for Roofs, Gutters, and Agricultural Structures
Long-Term Waterproofing
Roofs and gutters are your building’s first line of defence against the elements. Whether you’re managing a commercial facility, agricultural structure, or residential property, long-term waterproofing is essential to prevent leaks, rust, and moisture damage.
Harsh Australian conditions demand more than a temporary fix—they require a robust waterproofing system that can flex with temperature fluctuations, withstand prolonged UV exposure, and protect against structural deterioration.
At LRM Products, we specialise in commercial roof waterproofing systems engineered for a wide range of roof types and guttering configurations. From box gutters and parapets to metal or composite panel roofs, our flexible, liquid-applied membranes form a continuous, watertight seal designed for performance and reliability.
Built for Australia's roofs
We manufacture waterproofing solutions that are ideal for:
Commercial & Industrial Roofs
Warehouses, factories, retail facilities, and office buildings.
Domestic
Roofs
Houses, multi-unit dwellings, and renovations.
Box Gutters & Flashings
Creating seamless seals in complex drainage areas.
Agricultural
Roofs
Sheds, barns, and other farm structures exposed to high levels of moisture and environmental stress.
Accreditations
Standards Compliance and Durability
LRM waterproofing membranes have been independently tested and meet the performance requirements of AS 4654.1:2012 – Waterproofing membranes for external above-ground use, making them suitable for exposed rooftop and guttering applications.
Additionally, both VersEseal Rapid Build and VersEseal Top Coat are approved for use in potable water collection systems in accordance with AS 4020:2018, making them safe for use on roofs used for drinking water catchment.
Our products are manufactured under a certified ISO 9001:2015 quality management system to ensure consistent performance and quality control.
Versatile Application Across Roof Types
LRM’s roof waterproofing systems are designed to adapt to the diverse conditions found across commercial and agricultural roofing:
Roof Repairs and Resealing:
Seal ageing roofs and extend service life with a flexible, long-lasting waterproof layer.
Asbestos Roof Encapsulation:
Safely seal asbestos fibre roofing with a reinforced membrane barrier.
Gutter Waterproofing:
Roof Penetrations and Junctions:
Seal around skylights, vents, solar panels, and air conditioning units.
Irregular Roof Shapes:
Ideal for curved, pitched, or complex roof forms.
Composite Panels and Cool Rooms:
Waterproof fridge panels, solar units, and sandwich panels.
Our systems can be applied using a brush, roller, or airless spray equipment, with minimal disruption to operations and fast drying times.
Flexibility
Performance-Driven Waterproofing
With high elongation and excellent UV resistance, our waterproofing membranes are designed to handle the expansion, contraction, and movement common to roof and gutter systems.
VersEseal Rapid Build and VersEseal Quick Set provide a flexible and durable waterproofing layer that is UV stable and suitable as a final finish where heat or aesthetics are not a concern.
In applications where appearance or surface temperature are key considerations, the system can be finished with VersEseal Top Coat or VersEseal TopGrip, both available in any Colorbond® colour, to enhance protection and visual integration.
For added slip resistance in serviceable areas, VersEseal TopGrip can also be used to achieve an AS4586:2013 P5 grip rating.
