Liquid Waterproofing

Interestingly enough during this sealing exercise another area that had been water stricken some 110m above had also dried up and is no longer a problem

On all of these occasions Liquid Waterproofing have been successful in effectively sealing these water intersections and allowed for the development of the haulages and crosscuts to continue in a timeous fashion

How does your 10 Year Guarantee Work?

It is simple. As long as you don't alter the structure or interfere with our products, we shall repair those areas defined in your scope of work, for a period of 10 years after completion.

How successful is your injection waterproofing system?

Very successful. Please see our client's references.
The advantage with our system is that once we've treated an area, and there is still a small leak somewhere, we do not need to redo the entire area. At most we need to re-visit that specific spot to cure the problem. Hence our guarantee that makes provision for that.

Is the written Guarantee transferrable to a new owner?

Yes. Please let the new owner of the building contact us for verification.

Do you need to remove the tiles, screed and membrane to stop my leak?

No. Unlike traditional waterproofing methods, we don't need to chop up your tiles, screed and defective membrane.
We simply drill 5mm holes in the grout, between your tiles, and pressure inject Poly2Flex into the porous screed layers.

What if the tiles are butt joined? How will you solve that?

We can drill 5mm holes on the corners of each tile, and re-grout the drilled holes to match the surrounding tiles. We have done numerous sites with marble, granite and other tiles like this.

How are cavity walls treated?

Cavity walls are injected with different products, depending on the size of the cavity. Holes from 10mm to 16mm are drilled into the cavity, and the cavity filled to a pre-defined height.
This will effectively stop water migration through the cavity up to the defined height.

How long do I need to wait before redecorating the affected areas?

That will all depend on the severity of the leak and the volume of water and level of saturation in the affected structure. Humidity levels and volume of air circulation around the structure will also influence the drying-out -period.



As a rule of thumb expect to wait at least 8 weeks before redecorating walls as a first phase with a non-waterproof PVA paint.

This will allow the structure to 'breathe' while providing a perfect means to see if any more 'new' moisture is evident.

Please keep in mind that although we can stop future moisture migration, the moisture currently in the structure needs to dry out, and the sooner you paint, the more blistering you'll find. Hence the cheap PVA and then later, once the structure shows no more blistering, you can apply your final coat.



If you're impatient, a rental dehumidifier will speed up the process significantly, especially where air circulation is less, e.g. basements and cellars.
