Waterproofing Contractor

Guide To Your Waterproofing Membrane.

FAQ: My roof isn’t leaking. Why would I need to maintain my waterproofing membrane?

Your roof may not be leaking , but that doesn’t mean that your waterproofing membrane may not need some attention. One of the most common problems is build up of dirt and debris which can block outlet pipes. A roof which in normal circumstances wouldn’t leak. But, if it suddenly fills up 200-300mm deep with water, moisture could easily find a weak spot in the waterproofing and penetrate into the building structure. Other common problems include weathering related wear and tear to the waterproofing which could cause cracking at outlet pipes and around protrusions. Trades such as electrical, DSTV, camera and fibre installers don’t respect waterproofing layers. Thus, they often cut it or make holes in it in the course of their repair or installation duties.

FAQ: I don’t have budget for waterproofing maintenance. It’s a bad time.

Please contact a Waterproofing Contractor. There are various options available to overcome this. The Waterproofing contractor can in the meantime inspect the roof to assess the urgency of any work needed. If everything still looks fairly good, the job could be delayed for a few months and done at a later stage once the funds are available. Payment plans are an option with instalments over over 2-3 months.

FAQ: How will it affect my guarantee if I don’t undertake the maintenance on my waterproofing membrane every three years?

Technically this does render your guarantee null and void. However we are seldom so hard and fast with this. But the client does have certain obligations in caring for the roof, and it would be unfair to expect the Waterproofing Contractor to come back and repair problems, when the client hasn’t upheld their responsibilities.

FAQ: Can I not paint the roof myself or get my gardener to do it?

You could, but there is more to the maintenance than just applying a coat of aluminum paint. We are trained to inspect specific key areas on your roof that need assessing and resealed as necessary. Specialist equipment is required to undertake repairs which the average client doesn’t have.

FAQ: Will the Waterproofing layer last for the guarantee period if I don’t do anything to it?

Yes it will, but it could substantially shorten the lifespan of the waterproofing layer. Just like a car engine. You could easily drive a car for 100 000km without servicing it. However, not changing oils and filters will not make the engine last as long as it should. Likewise with the waterproofing, if it is not properly covered with the aluminum reflective and protective coating, the UV rays harm the bitumen and the essential oils in the waterproofing layer. Thus, resulting in drying out the membrane and losing its performance properties.

FAQ: The aluminum paint looks absolutely perfect and definitely doesn’t need to be repainted right now.

Depending on the roof design and type of waterproofing and batch of paint used, the performance of the aluminum coating can sometimes exceed expectations. Please contact us, the specialised waterproofing contractors to do an on-site assessment. If your aluminum is in perfect condition, only critical roof details will be inspected and the aluminum will be assessed again in a year or twos time.

FAQ: The aluminum coating seemed to deteriorate in a very short space of time.

This does infrequently happen for a variety of reasons. If the water run off of the roof is poor, the aluminum will deteriorate in the areas where water stands. Sometimes the bitumen base of the aluminum coating can be of variable quality and some batches perform better than others. Bitumen is a by product of the oil industry. Thus, although manufacturers strive to do there best, sometimes they have no option but to use what bitumen base is available at the time. Additionally, waterproofing laid onto lightweight screeds or wooden boarded roofs has more thermal movement. Thus, reducing the lifespan of the aluminum coating.

FAQ: What are the manufacturers recommendations regarding the care of the torch on waterproofing layer?

All major manufacturers and suppliers of torch on waterproofing membranes recommend their products are inspected every three years. There are some exceptions, such as when the waterproofing has a mineral chip weathering surface. But even they often don’t see out the full 10 years without some type of protective coating.

3 Do’s And Don’ts Of Gutter Cleaning & Maintenance.

Gutters Cleaning

Gutter cleaning and maintenance. Let’s face it, if your gutters are not doing what they are designed to do, water will enter your home and become a musty, mouldy, wet mess that no homeowner should have to deal with.

Here we have listed our top Do’s and Don’ts for gutter maintenance:

Gutter Do’s

  1. Clean Out Your Gutters AT LEAST Twice A Year. This is a vital part of keeping your gutters unclogged and in good working condition.
  2. Invest in Properly Installed Down Pipes And Down Spouts. If you only have 1 downpipe for your entire roof area, chances are you will experience overflow and leaks. Additionally, we recommend installing a downspout at the upper roof’s edge and a downpipe that leads down and away from your foundation. This will ensure adequate waterflow without causing overflow.
  3. Invest In Seamless Gutters. Seamless gutters are becoming high in demand as they are more durable and have less risk of leaking. DIY plastic gutters become brittle quickly and metal gutters rust in no time if not properly treated.

How To Find The Leak On Your Concrete Roof.

Are concrete roof inspections necessary? YES. Concrete roof repairs and maintenance are definitely necessary because concrete is susceptible to cracks, scaling and flaking (also known as spalling) due to general wear and tear of the material mixture. Concrete is moderately porous, thus it is vital that adequate waterproofing systems are installed.

Before we discuss how to repair and waterproof a leaking concrete roof, we first need to ask the most important question: Where Is The Leak Coming From?

Firstly, we recommend that roof inspections only be conducted by professional roof waterproofing contractors like ourselves. However, if you are familiar with roofs you can perform a basic visual inspection yourself. Here is a list of roof leaking signs and symptoms that may be visible on your concrete roof:

  • 1. Ponding Water:

    Concrete roof systems are not designed to hold water. Period. Thus, if you notice ponding water that is NOT slowly evaporating or isn’t drained within 48 hours, you need to call our waterproofing professionals for a free no obligation quote.

  • 2. Downpipes, Outlets & All Other Roof Drainage:

    Are your downpipes or outlets blocked? You can test this by conducting a flood test. Firstly (with the help of someone) take a hose pipe up onto the roof with you. With the hose pipe connected to the tap on the one end, place the hose into or in direction of your downpipes and take note of any water backing up onto the roof. If you do experience water back up or any slow flow of water, there might be dirt or debris blocking your drainage. Therefore, it is time for some downpipe cleaning.

  • 3. Cracks, flaking, Scaling Concrete:

    These are all signs of concrete that has not been waterproofed as these are the general wear and tear symptoms of concrete. If this is the case, give us a call and we will happily answer any questions or queries you have regarding the waterproofing options for your concrete roof.

  • 4. Loose Waterproofing Laps:

    if your roof already has a torch on waterproofing system installed but you are still experiencing leaks, you need to ask yourself 2 important questions; When last was my roof waterproofing maintained? Who installed my waterproofing? Majority of roof waterproofing systems come with a maintenance guarantee.

  • Concrete Roof Waterproofing
  • 5. Holes, Tears Or Any Other Imperfections in Your Concrete Waterproofing:

    The majority of other tradesmen and the community overall do not understand how waterproofing works. And you shouldn’t need to, that is our job. Having said that, we sometimes find that other contractors (ie. electricians, plumbers, satellite installers etc) will damage the waterproofing accidentally whilst installing or completing the service they were hired to do. Thus, resulting in water ingress.

  • 6. Do NOT Restrict Your Leak Inspection To Only Above The Leak Area:

Concrete is permeable, remember. Therefore, water has the tendency to travel before finding its way out again. Concrete waterproof coatings and other membrane waterproofing can increase the likelihood of water travel if it is damaged. Thus, resulting in water seepage you will not be able to visibly see due to it being under the coating or membrane.

  • 7. Plumbing Pipe Leak:

    If your leak is constant regardless of the elements, you might have a plumbing problem more so than a waterproofing problem.

Roof inspections and maintenance is important when taking on the responsibility of owning your own home or office. You might be able to conduct some parts of the concrete roof inspection yourself. However, our highly qualified waterproofing professionals conduct full concrete roof inspections free of charge. Call the waterproofing experts today for a free on-site assessment and we will report back to you on our findings along with a tailor-made solution for your leaking concrete roof.


The Importance Of Concrete Waterproofing

Concrete Waterproofing

Concrete waterproofing is the application of a suitable concrete waterproofing system on the concrete surface to create a breathable barrier so the concrete remains watertight. As we have explained in our other concrete posts, concrete is partially impermeable. Therefore, it absorbs any fluids or substances that may spill onto it. Leaving concrete susceptible to oil stains, leaks, cracking and other deterioration signs.

On What Surface Areas Is Concrete Waterproofing Applied?

Concrete waterproofing is applied to any concrete surface. Shopping centre parking bays, residential ground floor patios, warehouse interior floors, food stations etc. If you are looking to have your concrete floors waterproofed in your home, there are concrete sealers that bring out the beauty of the concrete by enhancing its appearance. This process also makes concrete a lot easier to clean.

A simple concrete waterproofing process is as follows:

  1. Remove all oil, stains, dirt, and dust from the concrete with a steel wire brush.
  2. Strip off any existing sealer (if any) from the floor surface.
  3. Roughen the concrete with an etching solution – Concrete coatings will not stick to a smooth concrete surface. Therefore, you need to ‘open’ the concrete by applying an etching solution. This will also decrease the alkalinity of the concrete.
  4. Apply a thin coat of concrete waterproofing using an industrial roller or sprayer.
  5. Wait for the first layer to dry before applying a second coat. The second coat needs to be applied in the OPPOSITE direction.
  6. Allow the concrete sealer to fully dry before exposing it to foot or vehicle traffic. If the area you want to waterproof is a high traffic zone, we offer after hours and weekend waterproofing services. Thus, reducing the amount of disruption for all parties involved.

What Happens If Moisture Gets Into Concrete?

Yikes! This is a scenario I hope you never have to experience. If there is moisture in concrete or there is a high percentage of humidity, concrete can take 60 – 90 days to dry. When concrete becomes wet, its strength decreases which of course affects it’s durability. On top of that, damp concrete becomes a breeding ground for mould which further decreases the concrete’s strength. Thus, resulting in severe aesthetic, functional and structural problems. Can you imagine walking or driving on concrete that has lost its strength rating?

Damp concrete cannot be waterproofed or sealed. The concrete needs to first dry completely before going ahead with any concrete sealer. You can dry concrete by increasing the air circulation.

Our Concrete Waterproofing Professionals

Concrete waterproofing is not a DIY process and should only be installed by a professional concrete waterproofing contractor. It is not as simple as clean, apply, dry. There are dozens of aspects to take into consideration prior to the application of the concrete sealer.  Let our expert concrete team assist you! We offer free, no obligation inspections and quotations.


The Importance Of Balcony Deck Waterproofing

Balcony Deck Waterproofing

To some, balcony deck waterproofing would be a no brainer. However, most building contractors consider it unnecessary and do not install it in order to keep the cost of the construction project down. However, balcony safety is a major concern especially when it comes to falling concrete. There are major consequences for balcony neglect.

Balcony waterproofing is important if you want to avoid severe structural damage to your balcony, the room below and the overall working condition of the balcony slab. We have seen situations whereby clients bought a house with a balcony which they did not know had not been waterproofed. As a result, the balcony structure deteriorated causing it to no longer be safe to walk on and became a huge safety hazard.

Tiled Balcony Waterproofing

Tile and grout are porous materials. Tile balcony leaks are the more common type of balcony structure to leak due to the water being able to seep through the tiles and grout and into the membranes below. A balcony waterproofing system needs to be chosen to best suit the current situation of the balcony or terrace. Paying careful attention to specific details on the balcony and the structure overall.

First Step During A Balcony Inspection

The first step during a balcony evaluation is to inspect the current condition of the existing flooring (the visible layer). Some easy to see causes of a balcony leak would include:

  1. Cracked Grout.
  2. Mould Growth Between Tiles.
  3. Mould Growth At Wall/Floor Junction.
  4. Tiles Pulling Away From Side Edge.
  5. Loose Tiles.
  6. Cracked Downpipes.
  7. Ponding Water (No Slope).
  8. No Balcony Threshold (The house floor level should always be higher than the balcony. You should step down slightly when walking onto your balcony).

Signs Of Leaking Balcony

Over-Tile Balcony Waterproofing Sealants

Although there are over-tile waterproofing systems, we avoid them as much as possible. Yes, they are sometimes cheaper than other waterproofing systems. However, tile sealants and coatings usually wear out a lot faster. Some areas faster than others depending on the amount of traffic the balcony receives. Even the best tile sealant products on the market will eventually wear down due to weather, aging, and general stress. Therefore, the waterproofing system presented to you by the waterproofing contractor needs to suit your balcony and its current state.

We do prefer under-tile waterproofing systems. This system does include hacking up the old tiles and comes with a 5 year guarantee. However, upon inspection of the balcony our waterproofing technician will advise which system will be best for you.
