sumon emam,
Thanks a lot ..very helpfull
-------------------------
Does this company (NIIGATA Construction Comapny)exists ?
I have tried to google it ..without succes.
Is this a patented method ? or can it be used without paying royalities ?
Are there other methods for bottom repair ?
is there a specific literature about botom rapair.
I will come back on the subject and try to put some other documents related to the subject
Thank you Sumon very much
