Say Goodbye to Temporary PU Injection. Say Hello to Permanent Solution

Addressing water leaks in basements, elevator pits, underground car parks, and MRT stations can be exhausting. If you’ve been depending on PU Injection but finding this temporary fix that will only last for few months, you’ve come to the right place. We are SG’s waterproofing basement specialists and we are here to provide a permanent solution using an advanced Korean technology called NPR Injection. We can do it right the first time.
