Unable to clear pages on stack

I am unable to clear pages on stack after logging out, have used this.navCtrl.navigateRoot(’/home’);.
I have been redirected to home page, but when I click on the back-button in the browser, app got redirected to the previous page.

I would suggest looking into Angular route guards.

I was using CanLoad router guard for my routes. Now, I have changed it to canActivate and its working perfectly. Thanks @rapropos.
