When building a home or any structure, high-quality materials are essential for durability and longevity. This is especially important in the Philippines, where typhoons, earthquakes, and extreme heat are common.

This guide will help you choose high-quality materials, including lumber, cement, steel bars (rebars), hollow blocks, and sand and gravel.

A. Lumber: Strong, Straight, and Well-Treated

 

 

1. Check for straightness – Warped or twisted wood can compromise structural integrity. Always pick premium wood with straight edges.

2. Look for minimal knots and cracks – Too many knots can weaken the wood. Also avoid lumber with deep cracks or splits.

3. Ensure proper treatment – Untreated wood is prone to termites and rot. Good lumber must be kiln-dried and chemically treated.

High-quality brands include: RM plywood, Santa Clara Marine Plywood, MLIM Phenolic Plywood, and others

B. Cement: Fresh and Properly Packaged

 

 

1. Check the packaging – Premium cement should come in well-sealed bags with no signs of moisture or hard lumps inside.

2. Verify the manufacturing date – Cement has a shelf life of about 3 months. Older cement may not perform as well.

3. Look for certification marks – Buy from reputable brands with Philippine Standard (PS) or ISO certification to ensure quality.

High-quality brands include: Holcim, Stallion, Century Peak, Republic, Mabuhay, and others

C. Steel Bars: Rust-Free and Properly Labeled

 

 

1. Check for visible defects – Avoid bars with cracks, pitting, or rust. Light surface rust is okay but deep corrosion weakens the steel.

2. Measure thickness – Some suppliers sell undersized steel bars. Use a caliper to check if the actual diameter matches the label.

3. Look for embossed markings – High-quality steel bars typically have manufacturer markings that indicate their strength and origin.

High-quality brands include: Keim Heng, SteelAsia, Pag-asa Steel, and others

D. Hollow Blocks: Dense and Well-Formed

 

 

1. Check for weight and density – A good-quality hollow block should feel solid and heavy, not light and brittle.

2. Look for smooth edges and uniform shape – Uneven or cracked blocks may indicate poor curing or weak cement mix.

High-quality brands include: JackBilt, Liteblock, Starcrete, and others

E. Sand and Gravel: Clean and Well-Graded

 

 

1. Look for Clean Sand – Good sand is free of clay, organic matter, and impurities. It should feel rough and grainy, not sticky.

2. Choose Well-Graded Gravel – Gravel should have a mix of sizes for better compaction and strength. Avoid overly fine or uniform particles.

Sand and gravel are usually sold under generic product descriptions. Make sure you buy from a trusted supplier to ensure their quality. 

Final Thoughts

These are just a few ways to check construction material quality. While it can be challenging, a reliable supplier simplifies the process. Choose established suppliers with industry experience and excellent customer service to ensure you make the right purchase with guaranteed quality.
