Building A House Foundation – Steps to Ensure It Lasts Long

Building a house foundation is the most important part of any structure because it supports the whole building and sends its weight firmly into the ground. Everything else in the house, including the walls, floors, roof, utilities, and people living there, rests on top of it. Distributing structural loads uniformly into the underlying soil is the fundamental function of foundations, which in turn provide stability. This mitigates the risk of significant cracks and damage caused by uneven building settlement over time when constructing foundations.

In residential construction, shallow and deep foundations are the two most common types. For low-rise structures and single-family homes, shallow foundations are ideal, extending no deeper than 1.5 meters. You can find mat slabs, floating slabs spread footings, and more. A deep foundation must be laid to reach bedrock or soil more than 1.5 meters deep. 

Buildings with multiple stories or residences on unstable or weak soils must have them. Common deep foundation systems include piles, piers, and caissons. Soil type, building loads, and available funds all play a role in determining the best house foundation type. A house is safe from settlement problems and remains steady and secure on a well-designed and -built foundation.

Foundation Construction Steps

Suppose you’ve wondered how to build a house foundation step by step; here, In that case, we have provided you with the necessary foundation constriction process and a clear roadmap for this crucial construction stage. 

Selection Of Site

When laying house foundations, choosing the correct spot is essential. For optimal load-bearing capacity, choose locations with compacted, stable soil. Stay away from sandy soils or loose fill because they can move around. 

Ensure there won’t be any flooding or a high water table on the property, as this could damage the house’s foundation. Conduct a comprehensive site survey to ensure underground cables, pipes, or big tree roots will not hinder the excavation and foundation work. Failure to take necessary precautions can damage your build a foundation walls and footings, particularly from tree ro

Excavation and Foundations

It’s time to start arranging for the big movers to come and shape the landscape. If the land already has houses and you don’t want to make any major changes, you can skip this step. After the dust settles, you should be able to make out the house’s layout. Construction of one area may block access to others, and the complexity of the house’s design determines how long this step takes. However, in most cases, it is fairly straightforward:

  • Installing the footings is like laying guide rails for the house’s layout. This is the bedrock, like a foundation for a wall beneath the earth.
  • Concrete or comparable material is poured into a mold after the ground is leveled inside the footings. This needs to be elevated sufficiently to deflect water away from the building.
  • Utilities and power lines are installed by punching holes in the concrete, which are filled with pipes and resealed.

Building a House Foundation Code

According to the Building a House Foundation Code, foundations are an essential and mandatory building component. Some terrains also prevent the house from warping or expanding, providing a foundation for the home. Foundations must be protected from moisture and termites and designed by a structural engineer. Foundational necessary measures include subfloor ventilation and waterproofing that extends approximately 100 mm above soil height.

Workers responsible for compacting excavated soil in construction use mini vibratory road roller compactor machines or walk-behind baby road rollers. Before resuming a build a foundation phase and framework, it is essential to compact the excavated soil. After digging the trenches, use a hand tamper or a mechanical plate compactor to compact the soil at the bottom. 

Since excavation and backfill are common wall-building processes, waterproofing is essential. In many cases, once construction starts, the surrounding soil must be filled up to a certain height above the house foundation, which means it will eventually sink below the soil/water level. To prevent rising dampness from the porous underneath, installing a waterproofing membrane that effectively seals the water above and below the surface is necessary.

When you see partially or completely underwater rooms, it might indicate that the building a house foundation is taking place underwater (because the ground and rocks are so saturated with water). To keep the water from rising to the surface as the construction continues, we employ a technique known as “below-ground tanking,” which involves connecting several pumps.

After the first build a foundation stage of your house is finished, this method is carried out through the completion of the area’s walls and full construction. It seals off the space between the soil and the membrane, making it more effective. Submerged areas are safeguarded from potential water leakage after pumps are removed and soil is backfilled, thanks to the membrane’s ability to repel additional moisture.

Anti-termite Treatment

Wooden structures and house foundations are vulnerable to termites, which can cause extensive damage. Therefore, before pouring concrete into house foundation trenches, treat them with a chemical anti-termite. 

Before termites can get into the foundation, the treatment will create a chemical barrier to keep them out. Choosing a termiticide suitable for the soil type and groundwater present is important when constructing a foundation. When applying the treatment, adhere to all safety precautions and product instructions.

Setting Up a Wooden Framework

Framing is typically the first thing that comes to mind when one imagines a house in construction. Frames are crucial in constructing the house’s vertical elements, similar to how house foundations and footings serve as horizontal guide plans. When a carpenter builds the framework and outline of a wall out of timber, this process is called framing. On top of that, framing is where the framework for the roof, floors, doors, and windows will be laid.

Unless you want to hire a construction company to subcontract the carpentry work (the easiest option), consider selecting a company. If you want a reputable, worthwhile, and trustworthy carpenter whom you can consult with and rely on regularly, you should hire them because they will be one of the most important contractors working on your house.

The process starts once you’ve decided on a construction partner.

  • If there is a wall in the room, the floor will be laid out with timber and then built up to mimic the shape of the wall.
  • Each of the wooden skeletons is fastened with metal straps; these should be strong enough to hold the roof framing in place.
  • The next step is to board up the windows and doors.
  • You can take a virtual inside tour while the walls are still being planned.

Curiously, this is the last instance that bad weather will be an issue during this stage of construction, which is a huge relief. The ‘Drying In’ stage, the point at which work can advance regardless of weather, is an important aspect of framing.

Framing The Roof 

The skeleton of the roof slating frame is now taking shape. You will also waterproof the substrate if you prefer a flat roof over a pitched one. There isn’t much difference between the ground and roof stages of the waterproofing process. Discussing it independently of the rest of the framing process is crucial.

Thanks to UV stability, flat roof waterproofing solutions from FoundationMD can be left exposed or treated with various post-installation finishes. The ‘total waterproofing solution’ that comes with one purchase includes the membrane, factory-bonded PVC profiles, premade internal and external corners, detailing strips, adhesives, and welding solvent.

Work with Reinforcement Steel 

Reinforcing concrete foundation walls and footings with steel rebar strengthens them and lasts longer. To ensure proper rebar design and layout during foundation construction, it is essential to seek the advice of a structural engineer. 

Pour concrete after positioning rebars according to the plan. For stability, use bar chairs made of metal or plastic to support the rebar cage. Rebar chairs provide proper spacing and concrete covering of the steel. Concrete is kept from cracking by the rebars, which support tensile loads. Get the rebar dimensions, spacing, and overlaps just right.

Construction of a Footing with Concrete

Following the specified water-cement ratio, mix high-quality concrete. Pour concrete into the foundation trenches in a continuous 18-24-inch lift. Compact the concrete and remove air pockets using a tamping rod to strengthen the foundation. 

Use a trowel to level and smooth the top surface for an attractive finish. Applying water to concrete for a minimum of seven days is necessary for building a house foundation. Strong, long-lasting foundation concrete is the product of careful mixing, pouring, and curing. Refer to expert recommendations for optimal procedures.
