In our home lives, we understand the value of maintenance. We wash our cars, check our gutters, vacuum our floors, and look after our health. The same care and maintenance are applicable to the buildings we protect through waterproofing. When certain areas are neglected or left unchecked, the consequences can be damaging and costly. 

When it comes to waterproofing solutions, Fosroc ANZ's Nitoproof systems provide trusted, world class results. The liquid applied range of membranes and topcoats, together with Nitoseal sealants, are made to withstand the toughest Australian conditions, and preserve the durability of the underlying structures they protect.

Colin Picton, ANZ Specification Manager, Waterproofing, Joint Fillers & Sealants, emphasises the importance of regular maintenance, and prompt rectification of any damage.

"Maintenance plays a crucial role in maximising the longevity and performance of waterproofing products," says Colin. "Keeping exposed areas clean makes it easier to check for cracking caused by movement or damage from falling debris."

"Checking for, and clearing a blocked drain is far more effective and financially palatable than spending big money on re-waterproofing and the ensuing disruption it causes. Following a planned cleaning and maintenance program not only keeps the structure looking good, it will help avoid unexpected costs moving forward."

In action: the benefits of maintenance


Fosroc ANZ Account Manager, Eric Repetto, recently joined the original applicators from Boss Building Maintenance on a routine inspection of the roof of Gaze-a-Way apartments at King's Beach on the Queensland's Sunshine Coast.

Four years ago, a waterproofing system of Nitoproof 510, Nitoproof 810, and Nitoproof Topcoat UV, plus joint sealants and Bond Breaker Tape was specified and applied. Despite the harsh coastal environment, the inspection revealed the waterproofing to be in excellent condition, underlining not only the durability of the Nitoproof products, but that early and scheduled inspections ensure the initial investment is maintained in peak-performing condition.

"Being right on the beach, this apartment block has full exposure to wind, rain and salts," explains Eric. "We conducted a visual inspection, recommended every 18-24 months, and specifically look for any fading, bubbling, cracking or movement of the underlying substrate that might cause water to penetrate."

Top maintenance tips


To ensure the longevity of Fosroc joint sealants, waterproofing membranes and coatings, here are some simple tips:

Stay ahead with regular inspections

Create and action a scheduled maintenance plan in accordance with AS4654.2 2012. Pay close attention to areas such as joints, corners, and terminations, and look for membrane cracking and blistering, bald spots or any other wear and tear. Storm damage such as hail or damage from fallen branches and debris can block drains. Record the inspection, including taking photographs.

Preserve performance through proper cleaning

Regular cleaning is essential for preserving the effectiveness of the Nitoproof system. Exposed to the elements, the membrane may accumulate dirt, debris, or other contaminants that could compromise its performance. Cleaning of coatings should be done using a neutral pH cleaner or detergent and applied to the surface using a soft bristle broom. Rinse off thoroughly with clean water under a low-pressure spray. In coastal areas more regular cleaning may be required to prevent the build-up of salt contamination, every 6 months is recommended.

Optimal drainage for long-term integrity

Keeping drains clear and functional prevents water accumulation, which can cause additional stress on the waterproofing membrane. Checking regularly, especially after storm or hail events is recommended to reduce the risk of leaks or structural damage.

Timely repairs for lasting performance

In the event of accidental damage or unforeseen circumstances, timely repairs are crucial for sustaining the performance of the Nitoproof waterproofing membrane. Before undertaking any repairs ensure the underlying cause has been identified and addressed. Any necessary repairs or maintenance should be carried out promptly by a suitably qualified contractor.

Commitment to waterproofing success

Regular inspections, proper cleaning, optimal drainage, and timely repairs are the cornerstones of effective maintenance.

"Regular and comprehensive maintenance practices optimise the durability of any waterproofing system," emphasises Colin. "By incorporating these practices into your routine, you can safeguard your structure, avoid costly repairs, and have peace of mind knowing that your waterproofing system is well-maintained."
