The Foundation Construction Process Explained

If you are building a basement for a newly constructed home, you need to have a better understanding of the foundation construction process before you can repair one to a high enough standard to create a room from the basement. Learning about the foundation construction process may also help you to understand the particular weaknesses of the foundation, giving you clues for where you should begin the repairs.

GroundWork

Before the basement can be positioned, you will need to start by excavating the ground where you want to build the basement. This begins not by using an earthmover, but by grading the lot to ensure that it is suitable for building. This is determined by sample testing the soil for compaction. Then the earthmovers dig large trenches, into which the basement footings are placed.

Once the trenches are ready, workmen place devices called batter boards into the basement's floor. Batter boards ensure that the building is completely level. This work may take around a week to complete, from the very beginnings when the earth is dug up to the laying of the boards in place, and then leaving the entire area to settle.

Setting the Foundations

Once the ground has been broken and the basement space has been excavated, the workmen install the rebars, which keep the basement together. Rebars are basic steel bars that support concrete; they are can be moved within the concrete until the concrete sets.

Rebar is often fitted with safety caps in order to prevent accidents. Rebars are common causes of basement damage, as epoxy or stainless steel bars can become cracked during installation, which will lead to chemical reactions in the concrete. Once the rebars are installed, the concrete is poured over the batter boards and the whole area left to set.

Adding the Walls

Once the concrete is set, the basement walls need to be started. Most modern basements are installed with radiant heat capacity, as heat easily escapes through basement floors and can lead to the home feeling cold.

Heat loss can be avoided by installing insulated stem walls. They are installed by setting up a row of polystyrene blocks which provides the mold for the stem walls. The stems are then poured into place, and any plumbing or cabling fitting while the stems dry.

Finishing the Basement

Once the stem walls are finished, the rest of the walls can be fitted. They are often made of breeze blocks, which are simply slotted into place and then plastered into place. Pipes and cables are trailed into the usable part of the basement. A concrete basement is poured then left to settle before the rest of the building is framed.
