Unbelievable good math for a block wall, but I think Jim is only going to have one block on the ground at the top of the pond. The liner itself is very strong, and once laid up and over the block, that block is not going anywhere. Not only would 6 inches of water have to move the block, but stretch the liner the same distance as moving the block.
Reinforced Concrete Wall Design Basics Mike O’Shea, P.E. This session is not intended to teach concrete design, but more of an awareness of why things are the way they are
A leaking concrete block / cinder block foundation is a challenging reality for many homeowners living in homes built between 1920 and 1980. On this page we explain why block foundation walls leak and how these types of foundations are waterproofed.
If the wall is load-bearing, you will need to carry the weight of the level above by other means, such as constructing a beam or buying a special laminated beam. Tools and Materials You Will Need. Replacing a load-bearing wall with a support beam requires surprisingly few materials. This project is more about labor than materials.

The theory behind my basement wall fix. Looking at my concrete block wall, you can see that it is being forced inward. The outside surface of the block is the compression side of the wall. The inside surface is being stretched-this is the tension side of the wall. Concrete has very poor tensile strength, which is why cracks are appearing.
material and methodology for strengthening block walls using highly workable strong grout which can be easilly pumped into an existing wall. Different mixes of fine grout were tried using different admixtures. Hollow block prisms, 11/2 blocks wide by 4 courses high, were grouted from the sides using hand pump. The
For many (perhaps the vast majority of) houses built before 1940, foundation walls were built directly on soil, without a concrete footing. Soil pressure at base of foundation wall will therefore be much greater (for existing and proposed conditions) compared to foundation wall on a concrete footing that is wider than the wall.
Reinforcement for Wall Openings. Most walls will have window or door openings or both. Creating a wall opening in a reinforced concrete wall creates extra stress around that opening especially at the corners. Window and door headers also known as lintels can be subjected to significant bending moment and shear forces depending on several factors.
Non-discounted retail pricing for: Concrete masonry block wall set with mortar on existing foundation. Quantity includes typical waste overage, material for repair and local delivery. Basic labor to install concrete block wall with favorable site conditions. Excavate up to 0.3m/1ft below grade. Layout pattern to minimize cuts.
Cinder Block and Brick Cracking and leaking are major issues and can eventually lead to bowing. Cracks run vertically, horizontally, or in steps along their joints. Horizontal cracks can be devastating for home stability. They will need to be filled, and drainage issues will need to be addressed.
The safety and reliability of reinforced grouted concrete block masonry is not accurately known in China. The present paper develops a probabilistic model to calculate the structural reliability of typical reinforced grouted concrete block masonry walls designed to Chinese standards, loaded concentrically and eccentrically in compression.
The wall labeled east wall on the interior picture would have at one time made the corner connection with the rough faced block on the exterior picture. Hope that makes sense. This same wall goes all the way to basement floor, which is about 4' lower than the area in the picture.
Lath Over Concrete Block – A Bad Idea The Florida Lath & Plaster Bureau discourages the use of lath over concrete masonry units (CMU) for a variety of reasons including water-resistance, durability, cracking and cost. There are several issues that arise when applying lath to CMU that should be discussed. To begin with,

The original carpenter attached jambs to the ends of the block walls, then hung a door between them. It's time to replace the door, and I'm a little unsure of the proper way to approach replacing with a pre-hung door. The old door is still in place, but as best I can tell, the opening in the block walls is 39 1/4 inches.
Locate the adjoining retaining wall so that the raised lip on the modified block is lined up with the raised lips on the opposite retaining wall. Finish installing the entire base course in both directions. Modify two more blocks, this time remove the raised lip from one block, and the right third from another.
A big advantage of using an externally applied, carbon-fiber reinforcement grid system is the speed and ease of installation. It permanently stabilizes bowed foundation walls with minimal disruption, no excavation, can be used in lieu of tiebacks, and is much cleaner than alternative techniques. Installers apply the crack repair epoxy through a ...

Figure 5 – Elastomeric spray applied to hollow concrete block (CMU) wall.
Why Cinder Block Walls Leak. A cinder block is much more porous compared to a standard concrete block or poured concrete. Cinder blocks are classified as permeable to water and water vapor (+10 perms). Heavyweight concrete blocks are semi-permeable (5 perms) and less so when the hollow cores are filled and packed with a slurry mix of concrete (about 2 perms).
