Remedial Waterproofing Solutions & Services

Remedial Waterproofing

Waterproofing is crucial for any construction project, whether residential or commercial. Proper waterproofing prevents water penetration or ingression, which can cause structural damage, mould growth and other issues. Without adequate waterproofing, a building can deteriorate quickly and become uninhabitable.

What To Expect From Our Waterproofing Consultants

At MJ Engineering, we specialise in remedial waterproofing services to repair existing failed waterproofing systems. We understand the importance of proper waterproofing in construction projects to prevent water damage, structural deterioration and potential health hazards such as mould growth.

Our experienced Australian waterproofing consultants have the expertise to identify the underlying cause of waterproofing issues. We provide a comprehensive solution that includes diagnosing the issue and providing a specification to prevent future water penetration.

Remedial Waterproofing Repair Process

With over 20 years of industry expertise, our waterproofing consultants at MJ Engineering Projects have developed a reputation for excellence in waterproofing solutions. Their approach combines innovative techniques with tried-and-tested methods to ensure the best outcomes. Our process involves:

Site Inspection & Report

Our waterproofing consultants will conduct a thorough site inspection, utilising advanced diagnostic tools to assess the extent of water damage and identify underlying issues. They will inspect the area where water ingress is reported to areas adjacent/below and provide initial findings in a detailed report, offering clear insights and preliminary recommendations for remediation tailored to the structure's specific needs.

Project Management

You can expect our waterproofing consultants to project manage/superintend the repair works and ensure the project runs according to the budget and schedule. They maintain transparent communication with the client, providing regular updates on progress and ensuring the project adheres to the highest standards, from initiation to completion and follow-up.


Options for Waterproofing Repair

When it comes to waterproofing repairs, there are several options available. If the damage to the waterproofing system is not too severe, it may be possible to repair the existing system. This is often the most cost-effective approach, as it involves our waterproofing consultants fixing the current system rather than replacing it entirely. Repairs include patching cracks or holes, sealing gaps, and re-applying waterproofing products.

A full system replacement may be necessary if the existing waterproofing system is beyond repair or if a partial replacement would not be effective. While this can be costly, ensuring the building is adequately protected from water intrusion is often necessary.

FAQs About Remedial Waterproofing Repair

Waterproofing systems can fail for several reasons, including:

  1. Poor Installation: Inadequate installation is one of the most common reasons for waterproofing failure. If the waterproofing system is not installed correctly, it may not withstand water pressure or other environmental factors. Poor installation can include incorrectly applying waterproofing products, using inferior quality materials, and not following the manufacturer’s installation instructions.
  2. Wear and Tear: Over time, even the most robust waterproofing systems can become damaged or worn out, leaving them vulnerable to leaks and other problems. Exposure to UV rays, changes in temperature and humidity, and mechanical damage can all contribute to wear and tear. Chemical exposure, such as in cleaning products or nearby construction, can damage waterproofing systems.
  3. Structural Damage: Structural damage to a building can also lead to waterproofing failure. If the foundation of a building shifts or settles, it can cause cracks in the walls or floors, leading to water intrusion. Similarly, if the building settles unevenly, it can cause the waterproofing system to stretch or tear, leading to leaks.
  4. Environmental Factors: Extreme weather conditions, such as heavy rain or flooding, can also cause waterproofing systems to fail. When a building is exposed to prolonged periods of heavy rain or flooding, water can seep into the structure and compromise the waterproofing system.

The impact of waterproofing failure can be severe and may include the following:

  1. Structural Damage: Water intrusion can cause significant structural damage to a building, leading to costly repairs. Over time, water can weaken the structure of a building and lead to the rotting, rusting, or warping of building materials. This can compromise the integrity of the building and make it unsafe to occupy.
  2. Health Hazards: Water intrusion can also lead to mould growth, which can be hazardous to human health. Mould can cause respiratory problems, allergic reactions, and other health issues. Additionally, water damage can create an environment that promotes the growth of bacteria and other microorganisms, harming human health.
  3. Cosmetically Unappealing: In addition to structural and health hazards, water intrusion can cause cosmetic damage, such as peeling paint or wallpaper, which can be unsightly. This can negatively impact the value of the building and create a negative impression on visitors or customers.

Regular waterproofing inspections and maintenance can help prevent more significant problems from occurring down the line. By detecting and addressing minor issues early on, building owners can avoid more extensive and costly repairs later.

It is important to consider local codes of compliance when undertaking waterproofing repairs. In Australia, waterproofing repairs must comply with the Building Code of Australia (BCA). The BCA outlines the requirements for waterproofing in various buildings, including residential and commercial buildings. At MJ Engineering, we can assist with the tender process to find a suitable contractor who adheres to all relevant codes and regulations for waterproofing repairs.

Insurance statistics show the highest number of waterproofing failures stem from issues with the balconies, terraces, rooftops in high rise dwellings and commercial buildings. There are a number of issues that may be the cause, including;
  1. Use of cheap/inferior materials to save money.
  2. Railing post and penetrations causing water ingress due to poor preparation and detailing.
  3. Failure to pick up building defects through the building surveyors’ inspection process.
  4. Inadequately waterproof detailing from balcony to wall interfaces
  5. Poor design criteria within many buildings which lack appreciation of water control, leading to costly damage that can be difficult to properly remedy.

The simple fact is that waterproofing membranes are only as good as the surface to which they have been applied or installed. The single biggest cause of waterproofing failures stems from poor workmanship, making it more crucial than ever to entrust your waterproofing needs to reliable and proven builders. It’s important to remember the failure of a waterproofing membrane or device can occur at any stage of the life of a building – it may fail straight away or after 1, 5, 12 or 20 years.

Simply put, water ingress is when water from outside gets into a building. It can happen in many different ways and for many different reasons in a building or property. 

To determine the responsibility of water damage, it is important to find out where the water damage or water leak started.

Common strata property is everything outside of the individual units or apartments. This includes the hallways, lobby, lifts, stairs, car parks, gardens, gyms, swimming pools, and so on. It also includes the walls that connect the units and flats, as well as any other space that isn’t on the building plan for a specific unit. If water damage to a strata property starts here, it usually could be claimed that the owners corporation is responsible for the water damage.

On the other hand, a unit or apartment is a private space in the house. According to NSW Fair Trading, “the basic rule is that everything inside the airspace of the unit, including all internal walls, fixtures, kitchen, bathroom and paint on the walls, is usually the lot and, therefore, the responsibility of the unit/apartment owner.” If the water damage comes from inside a unit or flat, the owner of the unit/apartment is usually responsible for fixing it.
