How do you repair a block wall?
Regrade the area maintained by the wall to redirect water flow away from the wall. This will reduce some of the water pressure that may be building up behind the wall. Drill additional weep holes into the wall to allow for increased surface drainage. Reduce the height of the retained material by regrading.
How do you brace a cinder block wall?
The most economical and effective way to stabilize a block foundation wall is done with vertical braces in the form of vertical steel beams placed against the wall. These beams are connected to the floor framing at the top and anchor bolted into the concrete floor slab at the bottom.
What causes concrete blocks to crumble?
Water is the primary cause for most crumbling concrete. Whether from flooding or from repeated rains, water eventually wears down the structure of a cinder block from the outside, causing it to flake off and crumble. If a block has not been properly cured, water can also infiltrate the interior of the block.

How do you estimate a cinder block wall?
After you have found the square footage of both your wall and your block, determining the number of blocks you need is as simple as dividing the wall square footage by the block square footage. If you’re using a standard 16″ x 8″ x 8″ block, find the number of blocks needed by dividing the wall square footage by 0.89.
WHY DO Retaining walls fail?
The main cause of retaining wall failure is poor drainage. Without proper drainage, hydrostatic pressure builds up behind the retaining wall. Saturated soil is substantially heavier than dry soil, and the retaining wall may not be designed to handle such a load.
How do you reinforce an existing retaining wall?
The wall can be strengthened by transferring some of the shear force to the base where the wall meets the ground. This can be done by either extending the footing of the base or placing concrete to thicken the base. Installing anchors or tiebacks is another option for extra strength.
How long do retaining walls last?
How long will my retaining wall last? For a permanent wall structure, the general lifespan is generally between 50 and 100 years. This does, however, depend on the conditions of the soil and groundwater at your site.
