Repair crumbling cement basement walls. More specifically it means removing all crumbling particles and applying a new coat of concrete on the damaged walls. Use a clean paintbrush to make sure that the entire area is free of cement dust and other debris. To repair deeper concrete defects or to replace chunks of missing concrete just add small stones to your mix.

Any untreated concrete can develop scaling a flaking or crumbling of the surface layer. Improvements must be made to the exterior grading to ultimately solve the problem. The walls in my 63 yr old full walk out basement are crumbling in spots.

The wall can then be painted with concrete paint but as long as there is moisture migrating through the wall the process will continue. The wall needs to be moist so that the old concrete won t leach moisture out of the mortar that you apply and cause the repair to fail. Step 3 place two large cement blocks tightly against the wall underneath the area to be patched.

First off brush off any loose material from the basement walls. Apply small amounts of water over a short period until it has absorbed water deep into the wall. The walls have been painted and the wall is crumbing in several places behind the paint and salt like particles have formed.

Scrub the crumbling areas of the wall gently with a stiff bristled brush to knock away small loose pieces of cement. Mist the wall with water and then apply a coat of thoroseal with a latex additive check on amazon. Wash the walls with an acidic solution check on amazon to neutralize the salt completely and allow to dry for a few hours.

Potassium and sodium salts draw water into the surface layer by capillary action that doesn t depend on open pores or faults. This helps to restore the structural homogeneity of the foundation and soundness of the building. In many older homes 1920s and 30s the crumbling is more severe.
