Concrete Foundation Waterproofing
Now architects can ‘wrap’ their foundations with Waterproof Lab’s Concrete Foundation Waterproofing Wall Seal System!
‘Do it right the first time’ is almost a cliché, but when it comes to waterproofing concrete, not doing it right the first time can have disastrous results. Pretty much the worst thing that can happen to a residential or commercial building is a foundation problem. Foundations are made of reinforced concrete, which is not waterproof and it also comes with cracks – having to fix a foundation issue will mean going through a very expensive and protracted intervention – so ‘get it right the first time’! For this reason aligning yourself with a reputable waterproofing company that supply specialised waterproofing material is a good idea.
Waterproof Lab’s Firestone RubberGard™ EPDM highly flexible membranes come in large, single rolls they can easily be adhered to foundations to stop ground water from penetrating the foundation and building structure.
Benefits of Concrete Foundation Waterproofing
Additional benefits of using Waterproof Lab’s Foundation Wall Seal System include:
- EPDM rubber membrane is highly elastic and will accommodate excessive stretching and building movements without a problem
- EPDM membranes will not tear, crack or split! They can, in fact, stretch in excess of 300% without damage.
- EPDM rubber concrete foundation waterproofing systems allow the substrate underneath it to breath. These products are vapour permeable, meaning any existing moisture or dampness can escape, while the membrane retains its ability to remain fully waterproof against the elements.
- EPDM membrane may be laid over asphalt, cement or other materials, by first laying a sheet of ‘Bidem’ to protect it from the original material.
- Firestone RubberGard™ EPDM is fire resistant
- EDPM is unaffected by extreme temperatures
- EPDM is the most environmentally friendly concrete foundation waterproofing product on the market, as it is recyclable, using less volatiles in its manufacture than most other products, coupled with its very low usage of global resources.
Concrete proof that Waterproof Lab’s Firestone Rubbergard™ EPDM foundation wall seal system is the way to go!

A rubber membrane that is available in rolls measuring 3m, 6m or 9m wide & 30m long, which can either be loose laid or fully adhered, to flat roofs of various substrates, with a lifestyle expectancy of 50 years. Click here to get an overview of the different EPDM roofing systems
With an integral UV protector in its manufacture, it has been proven to last in excess of 50 years, through a range of climatic conditions, including rain & snow, below freezing, to the hottest, ultraviolet laden sun;
Applying EPDM is a simple process, employing a specially formulated contact adhesive & sealants, to lay over a flat roof or other surface & once adhered, smoothed out to ensure a crease & bubble free finish;
Over more than 50 years, EPDM has been manufactured to a special blend of environmentally friendly materials, including UV inhibitors, which has been proven to last in excess of 50 years, under the most adverse conditions – successful where others have generally failed;
One of the benefits of EPDM, is that it does not require protection from the elements, which saves on on-costs over the years. This is unlike similar competitive products which a Silvakote or similar every 2-3 years to maintain the warranty and protect the membrane from the sun. However, should one prefer a coloured aesthetic finish, there is no reason that it shouldn’t be coated with an acrylic-based paint;
There is absolutely no reason why it should not work as well on pitched roofs. In fact it presents a very sensible option to waterproofing, with the ability to cover the existing roof cladding, without having to reroof, be it metal, tile, or whatever, & it will be particularly effective, due to the pitch enabling even greater water management;
This total installation cost will depend on the amount of detail required to waterproof. Size of roof & the number of water outlets or other penetrations, such as water &/r air-conditioning pipes, are a variables that can attribute the total installation cost. However, we would like to assess each situation on it’s merits, so we can estimate the least expensive price to assist our clients – so please get contact us at +27824151694 so we can discuss your project.
Each project has its own merits however in general, EPDM membrane may be laid over asphalt or other materials, by first laying a sheet of ‘Bidem’ to protect it from the original material.
No problem; simply lay a screed of cement over the protected EPDM, ensure is a ‘fall’ in the substrate to allow water to efficiently drain to the outlets and tile’. We do this all the time and this feature sets us apart from most waterproofing membranes in the market,
There are many materials which have historically been used for waterproofing flat roofs. However Waterproof Lab’s RubberGard EPDM membrane has become the membrane of choice in many countries, on account of its ability to stretch, reduce number of joints required, ease of application, protection against UV & cost effectiveness;
- It is most eco-friendly, having been used for years as a pool liner which sustains fish life & plant growth. Firestone RubberGard EPDM is an inert roofing material with limited environmental impact during manufacturing, installation and use:
- The initial production of the membrane has a low embodied energy number.
- The effectiveness of the EPDM polymer results in low quantities of polymer being required to obtain proper mechanical and physical properties.
- During the membrane’s service life, no toxic substances are released from the membrane, allowing collection and use of run-off rainwater for household applications.
- EPDM is a very highly durable material: Firestone RubberGard EPDM has outstanding weathering characteristics and a life expectancy up to 50 years.
- In regions like South Africa where Heat Degree Days outnumber the CoolDegree Days, a black EPDM membrane on top of a properly insulated roof can help to save energy and reduce associated carbon emissions.
- At the end of its service life, the membrane can be recycled and re-used

It has many benefits, which are listed in our ‘Benefits & Gains’ brochure.
For best results, you will require a measuring tape, a chalk line, a pair of scissors, a paint brush & a rubber roller;
It is always best to allow the substrate to dry before applying the membrane, as it is important to ensure that the bond between the membrane & the surface is not compromised.
EPDM is a blend of materials – Ethylene, Propylene, Diene Monomer, which imparts it’s outstanding flexibility, strength & waterproofing characteristics, making it the most ideal, long lasting, material to use for any waterproofing problems, most particularly, flat concrete or other, roofs;
EPDM is tough, flexible & resilient to foot traffic. Unlike most other waterproofing membranes, one of Waterproof Lab’s EPDM roofing systems main benefit is that it is also very easily & quickly repaired in the event of accidental damage ; simply cut a patch, apply a primer and Formflash patchto the damaged area, allow to dry & stick the patch down – & wallah! you once again have an uncompromised waterproof roof/deck!

Here is my experience with your wonderful company:
For years I’ve struggled with a leaking Eco pool. It’s been especially troubling with South Africa’s water shortage. I was sold a so called high end epoxy coating, which cracked, and I spent countless hours trying to fix cracks with various products. Nothing worked for a very long time. I wasted a lot of money. A number of people recommended Waterprooflab in Cape Town.
From the first call to final delivery this company has been incredible. They have an extraordinary product called Epdm. I’ve not had the slightest leaking since. It was a great pleasure working with the team who are passionate and hard working. I initially wanted to install the Epdm myself but after seeing what the team did I’m very glad I never attempted this, it requires great skill and care. The product and the intense labour required is not a cheap quick fix, it’s a reliable long term solution.
If I’d started with Waterprooflab I would have saved myself an enormous amount of trouble and money. The company has an excellent follow up policy and immediately attended to questions I had after the job was completed. This is a great company, world class service, product and expertise.
I have used Waterproof Lab on two occasions recently and have been very impressed with their service and expertise on both occasions.
In August, 2018, Waterproof Lab repaired a flat roof over a stoep, and lined a water feature at my house, that were both leaking. The flat roof was originally waterproofed with ‘Torch-on’ some 20 years ago and has leaked numerous places over the years.
Each time, the same product was used to repair the waterproofing, without permanent success.
It seems to be an inferior product, which is difficult or impossible to install on any flat roof that is slightly difficult, despite my using the most highly recommended installers (5 different firms over the years!).
I finally decided to try the EPDM product, based on published reviews and chose Waterproof Lab as the installer.
They impressed me at being extremely efficient at installing the product – and I am renowned for being difficult to please! I have had no Problems since then.
At the same time, they lined a water feature that was leaking – the builder had waterproofed it with a liquid product, that did not live up to to it’s s upposed claims. Again, the EPDM has shown no signs of leaking since it was installed.
Based on my satisfaction with their work at my house, In October, 2018, I asked Waterproof Lab to provide me with expert opinion on major Water leaks that have been occurring at a new block of apartments, Hugon Place in Claremont, of which I am a Trustee. They pointed out numerous problems that the builder/developer & well-known waterproofing company had failed to identify to us, or address properly, and the latter are currently attempting to fix these problems – which they have not managed to solve during the previous two years. Again ‘Torch-On’ had been used at this site; if it leaks again, I will be recommending to the other Trustees, that we appoint Waterproof Lab to install EPDM.
I would highly recommend Waterproof Lab for their expertise – from their expert advice, I would doubt that there is anyone in South Africa more knowledgeable than them – excellent service and what appears to be a much superior and more reliable product.’
Bruce & I would like to highly recommend your Company for its standard of workmanship & attention to detail, from the time we contacted you for assistance, to the time you handed us a not inconsiderable bill for work well & successfully completed.
As you know, we had endless trouble in trying to find a solution to the problem of stopping our continuously leaking low pitch flat roof, to no avail. Since 2000 we have been trying everything to alleviate our distress during rainy weather & it was only after contacting Waterproof Lab, that you managed to solve our problem for us.
The EPDM membrane which you guys applied in February, 2019, is the only solution that has finally worked! It’s such a weird feeling now when it rains, I don’t have to rush around putting drip catchers all over the house. It’s not cheap, but it does work….
And you’re also all such nice guys!
We’ve had ZERO issues with the section you did last year. Bruce recently completed the Polycrete on the remaining corrugated sections, but is not yet convinced that we need the membrane – time will tell, we may need you to come & quote after winter!
Thanks once again for helping us to overcome our nemesis.
We’ll recommend you to all our friends & acquaintances.
Water started seeping into our spare room after a crack formed in our wall following road construction.
We faced a potentially extremely costly and disruptive repair, but Waterproof lab were recommended to us through our plumber and we asked them to consult on the best solution.
The team were incredibly generous with their time, doing a few site inspections before coming up with a proposed repair plan. It was not an easy repair as required working with a number of contractors over a short period of time.
The team were always professional and on time, got the job done efficiently and with really good, quality results. We have had no issues following the use of the RubberGuard membrane, even during the most torrential rain. Thank you Waterproof lab for your excellent service, we would definitely use you again for any waterproofing needs!
