​Why use a crack isolation membrane?

Posted by Jeremy Hehn on

Crack isolation membranes often and interchangeably called anti-fracture membranes are used when the substrate (usually concrete) has small to large cracks. Concrete is especially infamous for cracking for many reasons and in most cases is pretty harmless, that is unless you are going to install tile on top of it! These seemingly innocent cracks can then transfer to the tiles laid over it and either crack the tile or grout or usually both, this is called reflective cracking. Crack isolation membranes essentially absorb movement in the substrate below the tile by moving and stretching separately from the tile installed on top. Pretty cool huh? Not to be confused with an uncoupling membrane. Yes uncoupling membranesdo the same thing but rather than absorb movement, they are a separate structure if you will “uncoupled” from the substrate therefore moving separately.

So now you know you need crack isolation but which one do you need? Not an easy answer, but we can certain give some suggestions and guidelines on selection.Simple crack isolation is going to be solved easily and quickly with a good peel and stick, or a primer and stick (might we recommend our very own Krack Kontrol crack isolation membrance J). Either way this is a great option for the DIYer because of the simplicity in installation. Uncoupling is generally best left to the pro’s, normally dictated by architects, and is definitely more often used in commercial situations. It is also more labor intensive and even slightly more costly but when crack isolation is imperative a great way to go.

So take a look through our catalogue of options and choose what’s right for you job, and as always if you need any help, have any questions please give us a call at 844-309-2945, we are always glad to take your calls. Take a look here at all of our Crack Isolation, Waterproofing, & Underlayment
