Waterproofing could be the most important job you can do in your home. Unfortunately, waterproofing often overlooked. Water leaks and damage not only cause aesthetic damage but it can cause severe structural damage to your property. Waterproofing is a rather expensive job and although the waterproofing cost can escalate rather quickly it is a necessary expense that could save you hundreds of thousands of rands later on. The longer you leave moisture exposure the more damage it can cause and the more money it will cost you.

When should you hire a waterproofer? 

We recommend taking a stroll around your home on a regular basis and keep an eye open for any signs of waterproofing. The earlier you spot any problems the less the waterproofing cost due to damage will be. If you spot any of these issues, you may need a waterproofing expert:

 Peeling paint or water bubbles

 Mold, mildew, and vegetative growth

 Cracked walls

 Wood rot

 Damp or watermarks

 Stains and rust

 Odours

It is always better to prevent waterproofing issues from happening. This is a good way to reduce your waterproofing price. So, if you’re starting construction on a new home or you’re doing any renovations, consult with a waterproofing expert beforehand to find out if you need to do any waterproofing work done. If you do, Kandua.com has a variety of waterproofing professionals with excellent reviews for you to get the best waterproofing prices.

6 Tips for hiring the best waterproofer for the job

Get quotes – Get as many waterproofing quotes as you can. Kandua.com is a great platform for this as you can get multiple quotes in under 60 seconds and then compare the waterproofing cost from pros.

Pricing – Don’t make your choice based on price alone. The cheapest waterproofing price might not be the worst choice – likewise, the most expensive quote doesn’t guarantee the best workmanship.

Reviews – Look for waterproofers with excellent reviews. Their reviews will give you a good indication of their workmanship as well as their work ethic. 

Experience – When getting a waterproofing cost, ask each company how long they have been in business for and what areas of waterproofing they specialise in. The longer they have been around, the more experience they are likely to have. 

Materials – Find out from the waterproofing contractor what materials they use. Do your research and find out if these materials are of good quality or not. Your local hardware store like Leroy Merlin might be able to help you with this information. 

Warranties – Speak to the waterproofing companies you are considering hiring. Find out from them if the waterproofing cost includes a warranty and if so, how does it cover the workmanship as well as the materials. Make sure you know how long you are covered for.

Types of waterproofing

There are two main varieties of waterproofing: liquid-based waterproofing membranes as well as sheet based ones. 

Liquid applied waterproofing membranes – This is either sprayed on or brushed on to surfaces. The thickness of the membrane can be controlled by applying more or less liquid to specific areas. Be cautious of making the membrane too thin as thin membranes are likely to tear which means water will be able to get underneath and cause damage. Contractors generally prefer liquid membranes because they form a joint free, seamless membrane. 

Sheet applied waterproofing membranes – This kind of waterproofing comes in sheets and is rolled out onto the specific area that is going to waterproofed. Then the waterproofing sheets are applied using a blow torch. In most cases, waterproofers will allow for an overlap that when heated forms a waterproof joint. As a result, water is unable to seep in through the sheets.

Good quality waterproofing should have the following properties:

UV protective – Exposure to constant sunlight can cause damage to the waterproofing which is why it needs to be UV resistant to prevent any sun damage. 

Elasticity – The membrane needs to have some flexibility. This is to ensure that it can move and expand with the foundation and stretch over cracks. 

Tear-proof – You’ll want to use waterproofing that won’t tear. The membrane often stretches and you don’t want it to rip and allow water to flow in. 

Breathable – Some membranes are designed to be breathable. This means the membranes allow water to pass through them in the form of vapour so that if water does get through, it doesn’t sit stagnant on the structure.
