How do you fix a crumbling concrete wall?
When concrete walls start to crumble, don’t panic. Patch. Basement walls often bear the brunt of a wet Oregon winter, flaking and crumbling. You can repair the damage by brushing on a bonding agent that lets new concrete stick to the old, then patching the wall.
Can crumbling concrete be repaired?
The Cure for Crumbling Concrete Steps
As long as the steps are structurally sound—meaning, they’re not spalling, flaking, or broken all the way through—you can repair most surface issues. If your patch is thicker, build the vinyl concrete patcher up in ¼ inch applications.
How do you resurface a concrete wall?
Fill in any cracks and gaps with concrete resurfacer. Use resurfacer for cracks 1/8-inch wide. For cracks 1/2-inch wide, fill in with concrete repair caulk. Insert the repair caulk tube into a caulking gun to squeeze out the agent.
What causes concrete blocks to deteriorate?
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.
Why are my basement walls flaking?
Many people do. You do have a condensation problem caused by the cool basement walls and the humid air found in basements. Water in the soil is constantly trying to get into your basement. The flaking is caused by this moisture – vapor pressure – that’s actively trying to gain entrance to your nice dry space.
Why is my cement crumbling?
Water. If too much water is introduced to the mixture, the cement and sand cannot bond with each other and will instead fall apart. As the concrete starts to dry, this results in a crumbling area where the particles aren’t sticking together.
What does spalling concrete look like?

Can you skim coat over concrete walls?
Skim coating can freshen up old concrete blocks and give your home or a wall on your property a new look. The process involves applying a layer of cement over the concrete block wall to cover grout lines or stains and give the surface a smooth appearance.
Will new cement bond to old cement?
Fact: Fresh wet concrete does not normally bond well to existing dry concrete. There is nothing in basic portland cement that will act as a bonding agent. Portland cement concrete works well in mass and provides great compressive strength but not bond. Concrete is marvelous stuff but in time it will deteriorate.
