What People Are Saying….

“Andreas is amazing! We needed some fairly extensive waterproofing in our new property. Andreas was the first person to answer our request, promptly assessed the areas, and was patient whilst we waited for approval for the works from our Body Corporate. He was also able to provide a few options in case the requests were denied. He then accomplished all works in 2 days! I absolutely recommend Alpha Waterproofing to anyone needing waterproofing/ damp-proofing!”

Why waterproofing is important

Excess moisture in the wrong places can cause havoc. Rising damp, mold and mildew, swelling walls, rotting timber, and even structural damage can be caused by faulty waterproofing. in fact, it is so important that it's required by law and must comply with Australian Standards AS3740 and AS4654.

Waterproofing a kitchen

The key things to waterproof are the counters, cabinets, and splash backs near the sink and stove. Most kitchen waterproofing is a combination of surface treatment and joint sealing. This way, water from leaks or spills will not permeate your cabinets before you can clean it up. If your kitchen could use this kind of waterproofing, a handyman or water proofer can help.

Waterproofing a bathroom

Bathroom waterproofing is applied before tiles are laid, using a combination of sheet and paint-on liquid membranes. Two coats are needed, each taking 24 hours to dry. The extra sealant may also be needed once the tiles are down. It is a job that can take up to four days, so allow plenty of time.

External waterproofing

External waterproofing is arguably the most important, as it keeps your house dry during rain and safe from the long-term impact of ambient humidity. Your home needs good waterproofing anywhere moisture can get into your home, including doors and windows, roofs and gutters, and walls and building foundations. All modern homes are waterproofed when they are built, but if you are seeing water damage in an old house or after a renovation, you will need a water proofer to diagnose the problem

Waterproofing takes time

It is important to be realistic about how long waterproofing takes. Most waterproofing uses liquid sealant that needs to dry completely, with multiple coats often needed. Minor joint sealing can be done in a day, but the caulk should have at least 12 hours to dry before being exposed to water. For under-tile or major external waterproofing, do not expect the job to be finished in any less than at least three or four days.
