Top 10 Mistakes to Avoid When Buying Bricks for Construction
Buying bricks may look simple, but one wrong decision can increase your construction cost, weaken your building structure, and create long-term maintenance problems.
In cities like Chennai, where heat, humidity, and coastal weather affect buildings, choosing the right bricks for construction becomes even more important.
Many builders, homeowners, and business owners focus only on price. However, experienced contractors know that brick quality directly impacts durability, plaster strength, heat resistance, and overall construction quality.
In this guide, we will explain the top mistakes people make when buying bricks for construction and how you can avoid them to save money and build stronger structures.
Why Choosing the Right Bricks Matters
Bricks are one of the core materials used in construction. Poor-quality bricks can lead to:
- Wall cracks
- Water seepage
- Structural weakness
- Higher plaster usage
- Increased maintenance cost
- Reduced building lifespan
According to construction experts, material-related mistakes contribute to a major portion of residential building defects in India.
That is why selecting quality bricks for construction is not just a purchase decision. It is a long-term investment.
Common Types of Bricks Used in Chennai
Before discussing the mistakes, let us understand the commonly used bricks in Chennai.
| Brick Type | Best For | Advantages |
|---|---|---|
| Red Clay Bricks | Traditional homes | Strong and durable |
| Fly Ash Bricks | Modern construction | Smooth finish and eco-friendly |
| AAC Blocks | Large projects | Lightweight and thermal insulation |
| Wire Cut Bricks | Premium buildings | Uniform size and elegant look |
Each brick type has different uses. Choosing the wrong type for your project is one of the biggest mistakeTop 10 Mistakes to Avoid When Buying Bricks for Construction
1. Choosing Bricks Only Based on Price
Many buyers in Chennai search for the cheapest bricks available. However, low-cost bricks often have poor compressive strength and high water absorption.
Cheap bricks may save money initially, but they can increase plaster consumption and maintenance expenses later.
Example:
A builder using low-grade bricks may spend more on wall repairs within a few years.
Pro Tip:
Always compare:
- Strength
- Durability
- Water resistance
- Size consistency
- Supplier reputation
not 2. Ignoring Brick Quality Tests
Good quality bricks should pass basic field tests.
Unfortunately, many buyers skip this step.
Important Brick Quality Tests:
- Drop test
- Water absorption test
- Sound test
- Hardness test
A good brick produces a metallic ringing sound when struck together.
Poor-quality bricks break easily and absorb excess water.
3. Not Checking Water Absorption Rate
This is one of the most ignored mistakes in construction.
Bricks with high water absorption weaken walls over time.
According to Indian construction standards, good bricks should not absorb more than 20% water by weight.
In Chennai’s humid weather, water-resistant bricks are extremely important.
4. Buying From Unverified Suppliers
Many local suppliers offer low prices but compromise on quality.
A trusted bricks supplier in Chennai should provide:
- Consistent quality
- Proper transportation
- Bulk availability
- Material invoices
- BIS-standard products
Warning Signs of Poor Suppliers:
- No quality assurance
- Irregular brick sizes
- Broken materials during delivery
- No customer reviews
Always buy from established construction material suppliers.
5. Choosing the Wrong Brick Type for the Project
Different projects require different types of bricks.
For example:
- AAC blocks are suitable for high-rise structures.
- Fly ash bricks are ideal for modern homes.
- Red bricks work well for traditional construction.
Using the wrong brick can increase structural load and reduce efficiency.
6. Ignoring Brick Size Consistency
Uneven brick sizes create:
- Crooked walls
- Excess mortar usage
- Poor finishing
- Construction delays
Professional contractors always check dimension consistency before bulk ordering.
Uniform bricks improve both structural quality and visual appearance.
7. Not Calculating Brick Quantity Properly
Many business owners either over-order or under-order bricks.
This creates:
- Material wastage
- Additional transportation costs
- Delays in project completion
Simple Formula to Estimate Brick Quantity
Here is a basic estimation method used in construction projects.
Step-by-Step Calculation
Step 1:
Measure wall dimensions.
Step 2:
Calculate wall volume.
Step 3:
Subtract openings like doors and windows.
Step 4:
Estimate bricks based on standard brick size.
Example:
A 1000 sq ft house may require approximately 70,000–90,000 bricks depending on design and wall thickness.
Always consult your engineer before placing bulk orders.
8. Ignoring Transportation and Storage
Transportation damage is common in Chennai construction sites.
Poor storage can weaken bricks before usage.
Best Practices:
- Store bricks on raised surfaces
- Protect from rainwater
- Avoid stacking too high
- Inspect materials during delivery
9. Not Considering Chennai Climate Conditions
Chennai experiences:
- High heat
- Humidity
- Coastal moisture
Therefore, thermal insulation and moisture resistance matter.
Fly ash bricks and AAC blocks are becoming popular because they reduce heat absorption compared to traditional bricks.
This can improve indoor comfort and reduce cooling costs.
10. Skipping Professional Advice
Some buyers purchase materials without consulting engineers or contractors.
This often leads to:
- Wrong material selection
- Structural inefficiency
- Increased labor cost
Professional guidance helps you choose the right bricks for construction based on:
- Soil condition
- Building design
- Budget
- Weather conditions
Pro Tips Before Buying Bricks for Construction
Here are some expert tips followed by experienced builders in Chennai.
Always:
- Compare at least 3 suppliers
- Check sample bricks before ordering
- Verify compressive strength
- Ask for bulk order discounts
- Inspect delivery quality
- Buy slightly extra to avoid shortages
How to Choose the Right Bricks Supplier in Chennai
Choosing the right supplier is equally important as choosing the right brick type.
Look For:
