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 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 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 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 Filling the hollow cores of an existing concrete masonry unit (CMU) wall is not, by itself, a dependable strengthening method. A successful structural retrofit depends on the wall’s condition, continuous cells, reinforcement, connections to the footing and roof or floor, foundation capacity, actual loads, and the complete load path. In reinforced masonry, grout helps

Introduction Miracle sealers are scams that cannot fix brickwork. They may promise permanent repair of cracks, moisture, or damaged mortar, but they fail to address real defects. A straight, honest approach relies on proper assessment and proven repair methods. Before you start, understand what needs addressing and what a DIY repair can and cannot cover.

Introduction Winter repointing is possible only when the mortar, brickwork, weather, and protection plan all meet the requirements for the specific mortar system. Postpone work if the masonry is frozen, frost-, ice-, or snow-covered, waterlogged, exposed to active precipitation, or if you cannot maintain the documented conditions through the required protection period. A heated, weather-tight

Introduction Repairing brick mortar washout at grade means restoring deteriorated mortar where the wall meets the soil and addressing shifts in ground moisture. The approach combines survey of damage with practical steps that respect historic materials and the effect of grading on moisture. It’s a hands-on task that requires careful observation and clear planning. Old

Introduction Failed brick flashing shows up as moisture intrusion at joints, leaving stain trails and damp spots on the wall. It signals that water is not being directed away properly. You’ll want to look for signs of staining, softness, or peeling where the flashing meets the surface. In practice, inspect for moisture clues around manufactured

Introduction Brick veneer bulging is when the outer brick layer appears to poke out or push away from the structure. This article focuses on what to watch for and why it matters in practical terms. It’s a hands-on topic, not a theoretical guide. Look for bulging along walls near openings, or where the veneer seems
