7 Common Material Mistakes Builders See in Sri Lanka When Building Houses
When it comes to building a house in Sri Lanka, even small mistakes in choosing materials can lead to big problems later. Contractors often see homeowners and builders making the same avoidable errors. Here are the most common material mistakes:
- Choosing Cheap Materials Over Quality: Many try to save money by buying the cheapest cement, bricks, or timber. While the upfront cost is lower, these materials often fail faster, leading to cracks, damp walls, and costly repairs. Quality materials may cost more initially, but they provide long-term durability.
- Buying Materials Without Proper Certification: Some materials on the market lack proper testing or certification. Using uncertified cement, blocks, or steel can compromise the structural strength of the house. Contractors always recommend checking certificates or test reports before purchase.
- Incorrect Block or Brick Sizes: Using the wrong size of bricks or blocks can make construction harder and weaker. It can also waste material and increase labour time, pushing your budget higher than expected.
- Ignoring Local Conditions: Not all materials perform the same in Sri Lanka’s climate. For example, certain types of paint, tiles, or wood may deteriorate quickly under high humidity or heavy rains. Builders need to select materials suited to local weather conditions.
- Mixing Materials from Different Suppliers: Some homeowners try to mix cheaper materials from different suppliers. This can lead to inconsistency in quality, creating weak points in walls, floors, or roofs. Contractors advise sticking to a few trusted brands.
- Overlooking Long-Term Maintenance Costs: Materials that look good on the surface may require frequent maintenance. For instance, low-quality paints may peel or fade, while poor-quality timber can warp. Choosing durable materials upfront reduces maintenance headaches later.
- Not Inspecting Materials on Delivery: Sometimes, even good materials can be damaged during transport. Contractors warn homeowners to inspect each delivery carefully before use to avoid future problems.
What Happens When You Use Poor Materials to Build Your Home?
Using low-quality or unsuitable materials in house construction can create serious problems over time. Contractors in Sri Lanka often see the negative effects of poor material choices. Here’s what can happen when materials are not carefully selected:
- Weak Structure and Early Cracks: Poor-quality cement, bricks, or steel can reduce the overall strength of your home. This may lead to cracks in walls, foundations, and beams, compromising safety and requiring costly repairs.
- Water Leaks and Dampness: Substandard roofing, waterproofing, or wall materials can allow water to seep inside, causing dampness, mold, and mildew. This not only damages your house but can also affect your health.
- Higher Repair and Maintenance Costs: Cheaper materials often break down faster. Frequent repairs, replacements, and maintenance can make your house more expensive in the long run, outweighing any initial savings.
- Poor Indoor Comfort: Materials that are not suitable for Sri Lanka’s climate can lead to uncomfortable living conditions. For example, thin walls may not keep heat out, or low-quality tiles may retain moisture, affecting temperature and humidity indoors.
- Health Risks: Some cheap or uncertified materials, like certain types of asbestos, paints, or treated wood, can release harmful substances. Long-term exposure can be dangerous to your family’s health.
- Reduced Property Value: Houses built with poor materials often face structural issues and visible wear faster than well-built homes. This can lower resale value if you ever decide to sell your property.
Why Poor Material Choices Happen in Sri Lanka
Poor material choices in house construction are surprisingly common in Sri Lanka, and several factors contribute to this issue.
One major reason is the lack of strict enforcement of building standards (Ex: the Establishment of a National Building Code for Sri Lanka is still under development), which allows low-quality or uncertified materials to enter the market. Many builders and homeowners are also tempted to cut costs by choosing cheaper options, especially when construction budgets are tight.
At the same time, frequent price fluctuations and shortages of construction materials make it difficult to source consistent, high-quality products. Additionally, hiring inexperienced contractors or unskilled labour can further worsen the problem, as they may not know how to handle materials properly or recognize poor quality.
Together, these challenges create a situation where shortcuts are often taken, leaving homeowners with materials that may fail long before their expected lifespan.
Warning Signs of Bad Material Choice
Choosing the wrong materials can have serious consequences for your house. Contractors in Sri Lanka often point out specific warning signs that indicate a material may be substandard or unsuitable. Some of them are as follows, and being aware of these signs can help you avoid future problems:
1. Extremely Low Price Quotes
If a supplier offers materials at a price much lower than the market rate, it is often a warning sign. While it may seem like a cost-saving opportunity, extremely cheap materials are usually of low quality and may fail sooner, leading to higher repair costs in the future.
2. No Quality Certificates or Test Reports
Reliable materials come with certificates or test reports showing compliance with safety and strength standards. If a supplier cannot provide these documents, it’s a strong indication that the materials may not meet required construction standards. Always ask for documentation before making a purchase.
3. Suppliers That Cannot Explain Product Strength or Standards
A trustworthy supplier should be able to explain the material’s properties, strength, and suitability for your project. If they cannot answer these questions clearly, it could mean the materials are unreliable or inconsistent.
Other Signs to Watch For
- Visible defects like cracks, chips, or inconsistent color in bricks, blocks, or tiles.
- Materials stored improperly, exposed to moisture or sunlight.
- Confusing product labels or lack of manufacturer details.
By paying attention to these warning signs, you can ensure that the materials you use will contribute to a safe, durable, and long-lasting house rather than creating problems down the line.
Tips to Follow When Choosing Materials
Selecting the right materials is one of the most important steps in building a strong, durable house. Contractors in Sri Lanka recommend following these practical tips to avoid costly mistakes:
1. Always Compare Quality, Not Just Price
While budget is important, focusing only on the lowest price can backfire. High-quality materials may cost more initially, but they last longer and reduce maintenance costs. Compare the strength, durability, and lifespan of materials before making a decision.
2. Check Certificates and Test Reports Before Buying
Reliable materials come with certification or test reports that prove they meet construction standards. Always ask suppliers for these documents, and verify that the materials are suitable for your project. This step can prevent structural issues and ensure safety.
3. Work with Trusted Suppliers and Reputable Contractors
Building your house with trusted suppliers and experienced contractors(like our team at Hello Builders), reduces the risk of poor material choices. Reputable professionals can guide you in selecting the right products, sourcing consistent quality, and avoiding shortcuts that compromise your home’s durability.
4. Inspect Materials on Delivery Before Use
Even high-quality materials can be damaged during transport or storage. So, always make sure to inspect every delivery carefully for defects, cracks, or moisture damage. This is really important because using damaged materials can weaken your house and increase long-term repair costs.
Additional Advice:
- Keep a record of material purchases and supplier details.
- Avoid mixing materials from multiple unknown suppliers.
- Ask contractors for recommendations on local brands with proven performance.
Following these tips ensures that your house is built with strong, safe, and long-lasting materials, saving you money and stress in the long run.
Steps You Can Take to Avoid Poor Material Choices When Building Your Home
Avoiding poor material choices requires careful planning and active involvement throughout the construction process. Here are practical steps homeowners in Sri Lanka can take to protect their investment and ensure a strong, long-lasting house:
1. Get Clear Material Specifications in the Contract
Before construction begins, make sure your contract clearly lists the type, brand, and quality of materials to be used. This creates a legal reference that holds the contractor accountable and reduces the risk of substitutions with low-quality products.
2. Ask for Quality Checks During Construction
Don’t wait until the house is finished to discover problems. Request that contractors perform quality checks at key stages, such as foundation, brickwork, and roofing. Regular inspections ensure that materials meet the specified standards and are installed correctly.
3. Hire Independent Inspectors if Possible
For added peace of mind, consider hiring an independent building inspector to verify material quality and workmanship. This extra step can catch potential issues early and prevent costly repairs in the future.
4. Set Aside a Contingency Budget for Quality Materials
High-quality materials may cost more upfront, so it’s wise to set aside a portion of your budget specifically for these products. This contingency ensures you won’t have to compromise on safety and durability due to cost pressures.
Additional Tips:
- Keep receipts and documentation for all purchased materials.
- Verify suppliers’ reputation before making large orders..
- Avoid last-minute changes in material selection, as they may compromise quality.
By following these steps, homeowners can minimize risks, avoid costly mistakes, and ensure their house is built to last.

FAQs
Why do poor materials fail quickly in Sri Lanka's climate?
High heat, humidity, and monsoons degrade substandard concrete and insulation, causing leaks and structural weakening within years. Tropical exposure demands UV-protected finishes and water-repellent options.
Why do contractors in Sri Lanka warn against cheap roofing materials?
Cheap asbestos or thin metal sheets fail to reflect heat in tropical climates, leading to overheating and leaks. They degrade fast from monsoons, causing structural damage and high repair costs. Properly insulated tiles or concrete ensure longevity.
How does Sri Lanka's climate affect building material choices?
High humidity and heat demand water-resistant concrete and UV-protected paints to prevent mold and fading. Flood-prone areas need elevated foundations. Ignoring this causes erosion. In fact, the use of climate-proof materials cuts long-term maintenance by 30-50%.
How does poor waterproofing affect homes built in Sri Lanka?
Inadequate waterproofing leads to damp walls, foundation erosion, and mold growth in the tropical climate. It causes cracks from moisture expansion and reduces home lifespan by years. Contractors emphasize full waterproof coatings on roofs, walls, and foundations to avoid these issues.
What poor electrical materials cause problems in Sri Lanka builds?
Ungrounded wiring and thin cables overload in humid conditions, sparking fires. Manual pool chemical systems corrode fixtures. Insist on calculated, certified installations.
