Is Versa-Lok good?
Stability. Solid VERSA-LOK units are some of the heaviest and most stable units, per wall-face area, in the segmental industry. They are also at least twice as deep as they are high, providing a low, stable center of gravity for each unit during construction and in the finished wall.
Do I need rebar in concrete block wall?
Concrete block walls may need reinforcing bars if they are load bearing or have a directional dynamic load/shear applied to them. Commonly, reinforcing bars are added to vertical block cells that are filled with grout, to bond beams, and to lintels laid up over openings.
What is the best mix for concrete blocks?
The standard mix for Concrete Blocks is 1:3:5, 1 part cement to 3 parts sand & 5 parts stone aggregate, by volume. 1 part cement to 8 parts mixed aggregate is much the same thing. Note that the ratio is different by weight, since the ingredients don’t have the same density.
What is mortarless dry-stacked interlocking masonry?
