Things to consider when selecting a Waterproofer

Waterproofing 101

Construction of a commercial or residential property is not an easy task. It requires precision, expertise, and, importantly, financing. However, a single mistake can render your building inhabitable. Stagnant water sipping through your basement, walls, or roof is something that should worry you. Water-related issues cause concrete cancers, cracks, or leaks.

Most of the water-related issues are related to poor artistry, negligence, and compromise on quality. A small error in the construction industry can rapidly become costly and unbearable. For such reasons, you must get it right from the first step to avoid regrets and headaches.

Whereas genuine companies offer quality service, there are devious entrepreneurs whose aim is only profit. To help you recognize and choose the best company for your waterproofing needs, here are some factors that you should consider.

• Background search
• Products
• Guarantee
• Longevity in business
• Certifications
• Insurance Covers
• Customer reviews
• Cost
• Background Search

Typically, the initial step in finding good waterproofers is searching. Ask around from your neighbourhood whether they know a company offering a waterproofing system. Word of mouth allows you to know how many companies are within reach.

Check out where the company is based or headquartered and if possible, visit the actual physical location. Verifying the existence of the company provides you with evidence of where to find it.
A severe business company should also have a website where you can do more background checks and see its success stories. The online presence of the company helps you to engage more and learn all about the company.


Waterproofers must prove that they use certified building materials. All products used by the company must adhere to the Building Code of Australia(BCA). BCA dictates that products used in waterproofing must pass the AS 4654 requirements.

The AS 4654 impose all products used in waterproofing undergo a reliability and durability test. The test requires product exposure to control samples, detergents, UV rays, heat aging, water immersion, chemical and bio resistance testing.

Products must also pass the AS 4858. The AS 4858 spell out the standard test procedures for moisture penetration in waterproofing membranes. It is essential to ensure that your company selection has compliance to set standards. Companies whose products do not meet or exceed these requirements will result in severe water problems in your building.


Choose a company that gives you a guarantee for its service. A contract is just a warranty that binds the company to be liable for defects in its product over a given period. Different companies offer various types of guarantees, depending on the nature and scope of the project. The contents of the security should be able to communicate what it covers in the warranty.

Some may limit themselves to materials only, which cover the replacement of failed materials. Others offer material and labour guarantees. Under such warranties, manufacturers cover the materials used while the contractor cover labour expenses. Some companies also provide overburden warranties. Here the contract stipulates that due to defective waterproofing, the company will cater to an additional cost. Such price may include tiling, painting, flooring, and the likes, dependent on the needed repair.

Companies that offer you a more extended guarantee mean that they trust their professionalism and the products that they use. Be keen to go through the guarantee contract so that you can understand the extent of the guarantee. When handling small scale projects such as residential homes, typically the warranty is about ten years or more.

Longevity in Business

Consumer trust allows businesses to be in operation for years. Companies that have stayed in the industry for a while mean that they have tackled many projects. Based on their project portfolio, it, therefore, means that they have better experience in waterproofing.

The more the company has been resilient in the business, the more it has refined its craft. Older companies most probably using the latest technologies and above-average expertise. Typically, this happens because they have experienced many challenges and new opportunities to better their staff and equipment.

Also, the longest-serving company in the business, the more trustworthy its warranty conditions are. Since the industry has interacted with many suppliers and manufacturers, it is more likely to offer better quality products at a subsidized price.


Waterproofing Sydney regulations demand that the companies in the business be certified. Certification enables you to separate credible companies from quacks. Waterproofing is an investment, and the best way to protect it is by getting a qualified company. According to the BCA building requirements, a waterproofing company requires several certifications. The fair trade department should license waterproofing Sydney companies. The appropriate trade department stipulates that they must have the right training for a company to be approved. It means that all your experts have received either of the following certificates from recognized institutions of learning:

• CPC 31408 III or CPC 31411 certificate in waterproofing construction or

• AS:3740 – 2010 Waterproofing of Domestic Wet Areas

Insurance claims are not a path that most people ever anticipate. We desire that we start the project and end without any hitches. However, it is not the case, and unexpected eventualities do occur. There is hence a need to ensure that your contractor has the necessary insurance for your sake. Some of the crucial insurance covers that you should consider are:

Indemnity: This is an insurance cover that ensures that the contractor has insured against damage resulting from their work. You can file a claim that the company has resulted in unexpected damage to your property. The insurance company, in return, fully compensates for the damage that you have incurred.

Work policy: It is a cover for employees that work at your business premise or homestead. Construction is a risky affair, and accidents that happen may result in serious injuries or fatalities. For that reason, it is essential to ensure that all workers have the necessary covers in case of accidents.

Public Liability: When an injury or damage occurs to a member of the public or a third-party due to the construction work, this insurance covers you. It means that the insurance company will pay for successful claims of those damages or injuries.

Customer Reviews

It is almost evident that former customer feedback is now an essential part before undertaking any transaction. It is the best way to prove that actually, the company walks the talk on what they purport to offer. A company that is not attentive to customer dissatisfaction or is mean with consumer feedback is likely to be a fraud. The customer support system ensures consumers are happy to boost the company’s reputation.

Read reviews of other former consumers and engage with them for their honest opinion. Where possible, you could visit them to see how the work was delivered and ask questions that worry you. Companies with many positive reviews mean that they are delivering on their promise. On the contrary, companies with numerous negative reviews indicate who you should strike out from your list of potential contractors.


It comes down to the budget. It will help if you approach companies that have friendly payment plans. While human nature is to minimize costs and get the best service, it is not always the case. Sometimes cheap becomes expensive, and you find yourself worse off than before because of a very lucrative deal. Cheap may mean low-quality products and poor artistry. Look for a company that is reasonably affordable with attainable payment plans. Request quotes and compare them to settle for the one that suits your need and fits into your budget.
