Changing the concept of waterproofing
How does the idea of “problem-free” sound to you?
Simply put, once you choose CWS technology, you enjoy problem-free waterproofing for the full-service life of your project and beyond.
CWS products extend the service life of projects, protecting against the ingress of water, forever. No more repairs, no more maintenance, no more suffering from leaks.

THE PROBLEM ABOUT WATERPROOFING INTEGRITY
We build projects to last for at least 50 years. If it’s infrastructure, this can be 80 or 100 years. Then we go and use traditional membranes and coatings that do not last more than 10 to 15 years. It really makes no sense to have to pay for re-waterproofing structures 4-5 times during their service life.
Traditional waterproofing will eventually leak and may keep leaking for years to come.
How long can the project owners suffer the repetitive aggravation of the “leak/suffer/re-pay/repair/re-leak” cycle? And why should they?
Often membranes are damaged during initial construction and then are covered with screed, tiles, etc., so the source of the leak can be impossible to find. Replacing them can be costly and certainly very disruptive. Businesses cannot afford suspending their activity for repairs. If they do, they lose income, which adds up to the total cost of the damage. Often this cost is never recuperated.
Carparks facing waterproofing problems stay unrepaired for years because the owners cannot afford to close them down for lengthy repairs, and water tanks may leak for ages before the decision is made to empty them for repairs, leaving communities without drinking water for several days or weeks.
Property developers risk their reputations over bad waterproofing, and get bad ratings from disgruntled clients on the web, causing their sales, or prices, to decrease as a consequence.
Designers are always on the lookout for a good product to rely on, as they face leaks in their rooftops and podiums soon after the project has been constructed. In certain parts of the world, designers resolve to use metal roofs lacking reliable materials.
Thousands of leaking basements and foundations around the world have to rely on pumps 24/7 to stay dry. How can this be “normal”?

CWS TECHNOLOGY IN A NUTSHELL



CWS helps contractors address issues from lack of manpower and from missing deadlines
Is the lack of an adequate workforce slowing your sites and affecting your cash flow? Do you face delays that may result in missing deadlines and facing liquidated damage claims?
CWS helps applicators slash project time and labor cost!
CWS products have been designed with the applicator/contractor in mind as they:
- Need many fewer people on site
- Dramatically reduce project time with their super-fast application
- Protect against missing deadlines
CWS100 vs. traditional membranes
CWS100: 6000 m² per day – no screed needed
Membranes & Screed: 100 m² of membrane & 50 m² of screed per day, per applicator
Example: 10,000 m² site
CWS100: 10 man days
Membrane & screed: 300 man-days
CWS Admix
CWS Admix is simply added at the batch plant or mixing truck and practically requires no on-site labor whatsoever.
