Why Register?

Without a valid registration key, SlabWorks™ is fully functional except for the length and width of the slab, which are fixed. Therefore, the program cannot be used for design or analysis unless a registered version is obtained.

Registration is required in order that updated version of the software can distributed to end users in the event that critical bugs or errors in the software are found. Without registration, there is no way to insure that all users of the program are notified.

How To Register

There is currently no charge for registration. This may change in the future, and updated versions may require the purchase of a license. The registered version of SlabWorks™ is only available to licensed professional engineers (civil, structural or geotechnical). SlabWorks™ is currently registered only to engineers, not companies. Two methods of registration are available, e-mail and regular mail:

By e-mail: To register, you must send an e-mail to SlabWorks@slabongrade.net. The subject must line of the e-mail must read ”SLABWORKS™ REGISTRATION”. In the body of the e-mail includes only your name (First and Last), state of registration, company name and PE number. We will only respond to e-mails from the domain associated with the company that is listed as your employer with the appropriate state board of registration. For example, if the state board lists your employer as XYZengineering, will we respond to e-mail from Bob.Jones@XYZengineering, but will not respond to Bob.Jones@msn.com. If you do not have an email address associated with your company’s domain name, or if the employer listed with the state board is incorrect, you will not be able to register the program by e-mail. Be prepared to wait as long as 3 weeks to obtain a registration code.

By regular mail: We will mail a registration code for the program to the address listed with the state board of registration for the associated PE number if a self-addressed, stamped envelope and a letter containing your name (First and Last), company name, state of registration, PE number and e-mail address is sent to:

The return address must be the same as the company address listed with the state board of registration. Be prepared to wait as long as 4 weeks to obtain a registration code. If the address listed with the state board is incorrect, you will not be able to register the program using this method.

Entering Registration Code

Once you have obtained a registration code, register the program at the startup splash screen by clicking on the Register button.

Enter the information in the registrations screen exactly as supplied and click on the OK button. This information is case sensitive. The program will tell you if the registration attempt was successful or unsuccessful. If the attempt was unsuccessful, return to the registration screen by clicking the Register button a second time and make sure the information entered is correct.
