Efficient products and unique knowledge in Trencless Tecnology.

I have not only  built one of Swedens leading companies in No-Dig construction field. I have also worked internationally as an expert advisor in Trenchless Technology for clients, consultants, contractors and equipment manufacturers.

Now, I have decided to once again focus on the Nordic market, but not as an entrepreneur. But by giving all the companies working with Trenchless Technology access to good products at a good price and good performance. I start with drill bits and screens, but more are on the way. 

I also intend to give the industry access to the experience I have gained during my 37 years by consultation and training. Contact us with your questions!
