The correct way to fill cracked concrete is to undercut along the cracks with a masonry chisel. This means you cut away the concrete along the crack forming a wider bottom to the cut. You must then clean away any loose debris with a brush and water. You then mix up expanding hydraulic concrete and force it into the crack. This works better if the crack is damp or even wet. The cement will expand and fill in the crack.
It is quite a bit of work but the patch will survive. Cracks though aren't the biggest problem. You have to get the water away from the foundation and the wall from the outside. Water percolates through cement it wicks through and in fact evaporation from the "dry" side helps to draw the water through from the outside. Water will rise up through a cement floor particularly one below grade with or without cracks. It will force paint to bubble and flake off. ----- Original Message ----- From: Rodger Hood To: [email protected] Sent: Sunday, August 10, 2008 8:36 PM Subject: [BlindHandyMan] wet carpet Upon finding the carpet wet after watering, my wife found cracks in the outer wall of our stucco home in California Central Valley. What would you guys and gals recommend to fill the long cracks some thin and some wider?
