Basement waterproofing

Advanced Waterproofing Solutions Ltd. (AWS) was founded in 2010 in Hong Kong by passionate individuals with more than 25 years of experience in the construction industry of South East Asia and the Middle East. With the commitment of promoting excellence in the field of construction, AWS an incorporated company with Astel Waterproofing LLC (Qatar and United Arab Emirates), is resolute in forging strong relationships with clients and providing a unique service that exceeds industry standards.

Waterproofing protects structures against water infiltration which can cause expensive and irreversible damage. It is mostly invisible after construction is completed. Every day the basement of a building, or the outermost layer of a tunnel, is exposed to intense fluctuations in moisture levels and temperatures, all contributing to its deterioration.

There are a variety of solutions that can be used in tandem or separately, depending on the severity and the cause of the damp problem in your basement.

Your Basement Waterproofing Problem Could Be Come From Several Things, Including:

* Improperly installed or missing downpipes and gutters
* Interior activities such as drying large amounts of laundry
* Leaking water pipes
* Cracked foundations
* Improperly graded slopes around your house *
* Groundwater
* Badly designed window wells
* Once you can determine which of these is causing the moisture, you will be better able to estimate how much it will cost to be fixed.

However, it is best utilized along with other prevention methods. By applying a waterproof coating to the interior of your basement, you might be able to keep moisture out, but it will still sit in the walls and foundations—which is not ideal.

We do Proper Installation of Downpipes and Gutters.
If your downpipes and gutters are improperly installed, damaged or completely missing, this will act to direct all of the water coming from your roof directly into your foundations and through to your basemen and we solve that problem with waterproofing expert’s.

However, take note that this solution on its own is generally not effective.

If you need to find a contractor for waterproofing in your home, school, building, office etc. then call us today. We are skilled and experienced in this industry with over 25 years of experience in the waterproofing & watertight industry, committed to our customers and our service.
