Complete Guide to the Foundation Construction Process at 92 Homes

Building a home is more than just bricks and mortar — it’s about laying a strong and reliable foundation that ensures the safety, stability, and longevity of the structure. At 92 Homes, we follow a step-by-step, technically sound process to begin construction, starting with one of the most crucial phases: foundation work.

This article outlines how we prepare the base of every home, ensuring it stands strong for generations to come.

Step 1: Soil Testing – Knowing the Ground Beneath

Before any excavation begins, we perform a detailed soil test to analyze the type, strength, and moisture content of the earth. This is critical because different soils respond differently to load and environmental changes. The test helps us determine how deep and strong the foundation must be for that particular plot.

  • Why it matters: It prevents future structural issues like cracks, sinking, or uneven settling.

Step 2: Excavation – Digging to the Right Depth

Once we have the soil report, we proceed with excavation based on its recommendations. At 92 Homes, we typically dig to a minimum depth of 2 feet and a maximum of 5 feet, depending on the soil condition and project requirements.

  • Excavation depth range: 2–5 feet
  • Tools used: Excavators, manual labor, and precision leveling instruments

Step 3: Termite Spray Treatment – Early Protection for Long-Term Safety

Before we pour the first layer of concrete (PCC), we apply a termite control chemical spray to the entire foundation trench. This is a critical preventative measure to protect your home from termite infestation, which can severely damage the wooden components and structural integrity over time.

  • Where it’s applied: Directly into the soil at the base and sidewalls of the excavation
  • When it’s applied: After excavation and before PCC
  • Why it’s important: Prevents termites from entering the structure through the ground

We use certified termite control solutions and ensure that the treatment is applied thoroughly and evenly, especially around wall junctions and future wood installation zones.

Step 4: Foundation Preparation – Layer by Layer

After termite treatment, we move to the actual preparation of the foundation. This involves three major sub-steps:

 

1. Plain Cement Concrete (PCC) Layer

We pour a 3 to 5-inch thick layer of PCC (Plain Cement Concrete) at the bottom of the foundation trench. This layer acts as a firm, level base for further construction and ensures that moisture from the soil doesn’t seep into the foundation structure.

  • Mix used: Standard ratio of cement, sand, and crushed stone
  • Function: Provides stability and prevents direct contact between soil and brickwork

 

2. Brick Base Layers

After the PCC sets, we begin the brick base construction:

  • First Layer:
    27 inches of brick ballast (also called brick rora or brick aggregate) is filled and compacted properly. This forms a strong base to support the rest of the structure.
  • Second Layer:
    Over the brick ballast, we lay 18 inches of solid brick masonry, providing added elevation and structural support.
  • Third Layer:
    The final foundational walls begin with 9-inch thick brick masonry, which becomes the base for the vertical wall structure.

Each of these layers is crucial to the overall load-bearing capacity and moisture resistance of the home.

 

3. Plinth Beam Construction (at Road Level)

When the wall construction reaches road level, we install a plinth beam — a reinforced concrete band that ties the structure together and ensures uniform load distribution across the foundation.

  • Dimensions: 9 to 12 inches wide
  • Reinforcement: 4 rebars made of 4 sutar steel (approx. 10mm) using 40-grade mild steel
  • Concrete Mix Ratio: 1:2:4 (1 part cement, 2 parts sand, 4 parts crush)

The plinth beam acts as a horizontal structural ring, resisting ground movement, preventing foundation cracks, and supporting future upper storeys. It also minimizes the effect of settlement or uneven load distribution.

Why Our Method Matters

By following this technically sound process, we ensure:

  • ✅ Structural Strength: Every layer supports the next, creating a firm, reliable base
  • ✅ Moisture Protection: PCC and compacted materials prevent dampness
  • ✅ Termite Safety: Early chemical treatment keeps the structure pest-free for decades
  • ✅ Load Distribution: Plinth beam prevents cracks from differential settlement
  • ✅ Future-Proofing: Allows safe construction of additional storeys

 

A Strong Foundation = A Safe Home

At 92 Homes, our foundation construction is engineered for strength, designed for safety, and executed with precision. We don’t just build homes—we build them to last.

Our attention to detail at every stage ensures that your home not only looks great but is structurally sound from the ground up.
