Crafting with Concrete

Introduction Waterproofing block foundations means choosing between coatings, membranes, or drainage boards to keep moisture from entering the structure. Coatings seal the surface, membranes create a continuous barrier, and drainage boards help direct water away from the wall. Think about how water will contact the wall and what prep is needed before any product is […]

Introduction Vertical cracks in block walls are cracks that run straight up and down the masonry and are often linked to shrinkage or movement in the structure. They can form as the wall settles or as the blocks and mortar dry and adjust over time. Monitoring these cracks involves simple visual checks and noting any

Introduction Stair-step cracks are diagonal cracks that follow mortar joints in block walls, forming a stepped pattern. They often point to movement in the wall due to settlement or shifting soil. In homes and foundations, these cracks can appear after changes in moisture or load. Not every stair-step crack is a sign of a major

Introduction Cutting concrete block units involves trimming and finishing blocks with a focus on dust control and clean ends. This introduction provides practical, hands-on guidance for selecting tools and following safe, efficient techniques. You’ll learn dust control steps, proper cutting methods, and the safety gear that helps you work cleanly. From saws and masonry bits

Introduction Block mortar consistency is the level of sticky workability the mix has when you hold it in your hand. A good consistency should grip blocks firmly without slumping, and it should not be so wet that it oozes or separates. Use a simple hand test to feel how the mortar grabs and releases, and

Introduction Stringline setup for straight block walls is the method of using posts and batter boards to mark a straight line and guide brick or block alignment. It helps you keep the wall edges true as you work from one end to the other. You’ll plan the layout, set up a taut line, and verify

Introduction The first course layout establishes the baseline for squareness and corner alignment. Laying it out means marking where each block will sit and how the corners will meet. Getting this line right prevents future misalignment and saves work later. Check squareness by measuring diagonals across the intended corners and adjusting as needed. Mark the

Introduction Block bond beams are horizontal reinforced concrete bands built into the top of block walls to tie sections together and resist bending. They help transfer loads to the foundation and keep the wall stable. In practice, they act as a continuous tie across the wall, improving overall strength. Common materials and forms for bond

Introduction Tying new block walls into existing ones involves overlapping rebar to create a continuous path for load transfer and crack control. This requires careful placement and proper lap details so the new and old walls behave as a single structure. Follow manufacturer guidelines and local building rules for lap length and rebar spacing. Plan

Introduction Grout filling a block wall is a method to add rigidity by binding hollow cores and masonry units together. This article explains what you can and can’t do as a DIYer. It focuses on practical steps, safety, and what to check before you start. Before you begin, confirm local rules and product instructions, and
