FAQ About Commercial Waterproofing

Commercial waterproofing involves applying techniques and materials to prevent water infiltration into commercial buildings, such as offices, retail spaces, and industrial facilities. In Sydney, with its variable climate that includes heavy rainfalls, waterproofing is crucial to protect buildings from water damage, prevent mold and mildew growth, and maintain the structural integrity of the property.

Virtually all types of commercial properties in Sydney can benefit from waterproofing services. This includes office buildings, retail centers, warehouses, hotels, hospitals, schools, and more. Waterproofing is especially important for buildings with basements, as well as those with flat roofs or balconies that are more susceptible to water accumulation.

Common signs include visible water leaks, damp walls or floors, a musty smell (indicative of mold or mildew), peeling paint or wallpaper, and efflorescence (white, powdery substance on walls). Regular inspections can help identify these issues early.

The effectiveness of waterproofing methods depends on the specific needs of the building. Common methods include membrane waterproofing (using liquid or sheet membranes), cementitious waterproofing (ideal for internal wet areas), and bituminous coating. A professional assessment is necessary to determine the most suitable method.

The lifespan of waterproofing systems can vary, but generally, a well-installed and maintained waterproofing system can last up to 10-15 years or more. The longevity depends on the quality of materials used, the expertise of the installation, and environmental factors.

Yes, in Sydney and across NSW, commercial waterproofing must comply with the Building Code of Australia (BCA) and Australian Standards such as AS 3740 for waterproofing of wet areas. These regulations ensure that waterproofing is done to a standard that protects the safety and integrity of the building.

Yes, older commercial buildings can be waterproofed, but they may require more preparation work, such as repairing existing damage or updating drainage systems. It’s important to have a thorough evaluation done by a waterproofing professional to determine the specific needs of an older building.

What Our Clients Say About Us

“I’ve had Predrag manage four projects for me for over four years, and I’ve been completely satisfied. Predrag was completely professional, starting with the quotes for the jobs he undertook, breaking them down into sections. He also has an eye for detail and makes suggestions for anything he feels needs attention. He’s punctual and reliable, and so I couldn’t recommend Predrag highly enough.”

Helen Muir

“Predrag Loncar of SMR Builders was hired in March 2020 to carry out remedial repairs to our property, to reverse bad building practices during the original build 20 years ago, which had led to extensive damp problems in the walls. His initial inspection was detailed, wide-ranging and thorough. After we had accepted his quote, he made sure that he consulted and liaised with us at every stage of the work. When he opened the walls for repair, in several places, he discovered further problems which he carefully explained to us and then offered suggestions for repair. With Predrag and SMR Builders, you will get someone passionate about his work, who has a detectives’ nose for seeking out the best possible solution and who wants to achieve the best possible result. He is very aware that his work is in someone’s home, and he constantly stresses to his men to be respectful of their surroundings. We are very happy to say that the team of Christian the foreman, with Ivan and Caramba, were very pleasant to have around, and did not cause us any problems at all. We have no hesitation in recommending Predrag and SMR Builders; it would be very difficult to find a better builder for your remedial work.”
