Lippage control system with stretchable strap portion

A method for reducing lippage in a plurality of tiles comprising the steps of:

• (i) providing a substrate configured to be bondable to said plurality of tiles;
• (ii) providing a base;
• (iii) providing a first tile disposed adjacent said base;
• (iv) providing a member extending from said base;
• where the member has a distance from the base as a longest dimension along a member longitudinal axis;
• a width of the member, which runs in a line parallel to a joint longitudinal axis of a joint containing said member, has a shorter dimension than said longest dimension, and is a dimension that is longer than a tapering thickness dimension of the member in a line which is orthogonal to the joint longitudinal axis;
• and where the member has a thin walled region surrounded by a thicker walled region and the thin-walled region is oval in shape;
• (v) providing a cap;
• (vi) causing said cap to engage and surround a portion of said member;
• and
• (vii) providing a pressure onto a surface of one of said plurality of tiles by compressing with pressure said cap, and thereby causing said member to stretch along said member longitudinal axis.
