🔢 Calculation StepsStep 1: Calculate wall area
                                Area = Length × Height
Step 2: Calculate blocks needed (12.5 pcs/m²)
                                Blocks = Area × 12.5 pcs/m²
Step 3: Add 5% waste factor
                                Total Blocks = Blocks × 1.05

Material Guide

Choosing the Right Batako for Your Project

Not all hollow blocks are created equal. In the Philippines, you'll find different classes of batako - Class A, B, and C. Class A offers the highest compressive strength (around 500 psi) and is ideal for load-bearing walls. For interior partitions, Class B or C might be sufficient and more budget-friendly.

Look for blocks with uniform color and sharp edges. A good quality batako should produce a clear ringing sound when tapped. Avoid blocks with visible cracks or crumbly surfaces.

Cost Saving

Maximizing Your Cement Usage

The standard 1:4 cement to sand ratio works for most applications, but you can adjust based on your needs. For areas exposed to moisture, consider a 1:3 ratio for better water resistance. Always mix cement thoroughly and use it within 1-2 hours of mixing.

Local tip: During rainy season in the Philippines, cover your cement bags with plastic tarps and store them on wooden pallets to prevent moisture absorption. Wet cement loses its binding properties quickly.

Local Practice

Philippine Construction Standards for Mortar

Filipino masons have developed techniques suited to our tropical climate. The ideal mortar consistency should be similar to creamy peanut butter - not too dry, not too runny. This ensures proper adhesion while allowing for minor adjustments during block placement.

Remember to soak your batako in water for a few minutes before laying. This prevents the dry blocks from absorbing moisture from the mortar too quickly, which can weaken the bond. This simple step can significantly improve wall strength.
