Granular Sub-Surface Preparation Guide

 

Proper preparation of the sub-surface is critical
to the long term success of your project.

The ideal sub-surface for the SofTILE® KrosLOCK system
is properly cured concrete or asphalt. The KrosLOCK
system was also designed to be installed over a properly
leveled and compacted sub base of 3 to 4 inches of aggre-
gate of the correct size, type and consistency, followed by
a minimum 1 inch layer of properly leveled and compacted
(1/4 inch minus) “chip & dust” or “granite screenings”.

Due to the importance of proper sub-base preparation,
SofSURFACES has created this separate instructional
guide specifically addressing the correct sub-surface
preparation techniques required to obtain a surface
suitable for a tile installation.

By investing a few minutes in this manual you will save
valuable time on the project, while avoiding some of the
most common errors associated with the base installation.
