This is an excellent example, making obvious a great difference between Professional and Amateur.

New multi-level building in Box Hill. The Builder decided to save money and do the External Waterproofing on his own, without any Professional help or advice. It has been less than a year since the Builder have done so called “Waterproofing” – and now we can see the results.

The Owner was shocked to see the basement of his new house leaking after every rain.


She asked our advice on this situation – and we were happy to explain, how the Waterproofing shall be done and why the water is getting in.

First of all – because the Owner didn’t want to dig and Waterproof outside, we’ve agreed to complete the Internal Waterproofing using the Negative Pressure Waterproofing Membrane.

The whole length of the cold joint was injected with Polyurethane Crack Injection product, then filled with Hydraulic Cement and covered with Waterproofing Membrane.

As recommended, the Owner asked to complete External Waterproofing of one of the external walls as well.

To do that, we had to take off the peeled and bubbled old membrane, that was applied by the Builder.

The Owner was pleasantly surprised, seeing the difference between the Professional Waterproofing and the one, that has been done before.

Now she is making the decision to dig all other walls and do the External Wall Waterproofing like we’ve done on this wall.

This example is showing, that everyone shall do his own job – Bricklayer shall lay bricks, Renderer – do the rendering, Painter – painting, Waterproofer – waterproofing.

If the painter starts to lay bricks and the Builder is making the Waterproofing – the result will be like it was shown in the beginning of this article.
