StretchLearn Course
Concrete slabs, crack and step repair, and brick and block laying, taught the way working masons actually do it.
Course Overview
This course takes you from your first bag of premix to a finished slab, a repaired set of steps, and a laid course of brick or block with tooled joints. You will learn the water ratios, curing rules, and jointing methods masons use every day, plus how to diagnose and repair cracks the right way. No software or design tools required, just bagged materials, hand tools, and the habits that keep work level, plumb, and lasting.
Learning Outcomes
Mix concrete and mortar to the correct water ratio and slump for the job
Form, pour, screed, float, and cure a small concrete slab that resists cracking
Diagnose crack types and repair them with the right product for the gap width
Patch broken concrete steps and spalled edges with bonded vertical mortar
Lay a level, plumb course of brick or block on a proper mortar bed
Tool and point mortar joints for a weather-tight, professional finish
Curriculum Preview
Preview the course structure, see how the modules build on one another, and understand the path this program is designed to take you through.
Learn what is actually in the bag, how cement, sand, and aggregate work together, and how to mix concrete and mortar to the right consistency without ruining the batch.
Take a small slab from string-line layout through forming, pouring, screeding, floating, and a proper cure that prevents cracking.
Diagnose why concrete fails, then match the right product and method to repair cracks, broken step edges, and surface spalling so the fix lasts.
Lay units on a footing or base with consistent mortar joints, keep the work level and plumb with a line, and finish with tooled, weather-tight pointing.
Built for Application
This program is designed around progression: focused lessons, structured modules, applied resources, assessments, and a course rhythm that turns information into usable capability.
