Foundation Types

Raft Foundation

A raft or mat foundation is a large concrete slab that covers the entire footprint of a building. It distributes the building load over a large area, suitable for weak or expansive soil conditions. It is a large concrete slab that spreads the load from the structure over a wide area of soil, providing stability.

The construction process for a raft foundation typically involves excavating the site to the required depth, compacting the soil, and then pouring concrete to create the foundation slab. Reinforcement steel is often used within the concrete to provide additional strength and help prevent cracking.

Combined Footings

A combined or strip footing is a type of foundation used in construction to support multiple columns or loads within a relatively narrow area. It is designed to distribute the load from adjacent columns to the soil efficiently while minimizing differential settlement.

Combined footings are suitable for use in a variety of soil conditions, including cohesive soils, granular soils, and expansive soils. The design of the footing takes into account the bearing capacity and settlement characteristics of the underlying soil.

Deep Foundations

In construction, a deep foundation refers to a type of foundation that extends deep into the ground to transfer the structural loads of a building or structure to deeper, more stable soil or rock layers.

Deep foundations are used when the soil conditions near the surface are not suitable for supporting the loads of the structure.

Basement Waterproofing

Waterproofing is an added layer of protection for your floors and walls. It can be done from the inside or the outside of your building or home. It can also help seal the concrete to help prevent flooding and leaks in the event of oversaturation in the soil below.  

Basement Window Infill

If there is any damage between the top of the window and where it aligns with the wall, a window infill can be installed to repair the gaping that may be occurring. Window infills also provide your home protection from the elements. It can be installed as an added protection from rain, snow, etc.

Basement Flooding

One of the main issues to occur in basements is flooding. At one time or another, a basement may flood. Flooding may occur due to a lack of proper water drainage during heavy rain or snowfall. When lots of rain or snow falls at faster rates the soil below may begin to shift and become too saturated causing leaks and flooding in your basements.

Caring For Flooding

After a basement has flooded, it is important to remove the water as soon as possible. Removing the water quickly can help reduce the amount of damage done to your floors and walls. If flood water is not attended to quickly, it can increase the amount of damage done to your basement as well as increase the risk of mold and mildew growing.

Why Quality Materials Are Important

When building a good and strong foundation, the quality of the materials used is important. The better quality the materials are the more secure and durable the foundation will be.

Foundation Cracks

Not all foundation cracks are serious. Some cracks can be as simple as old or dry concrete. As seen in the image below. 

Building a Foundation


Properly preparing the site is essential. This involves clearing the area of any debris, vegetation, or obstructions. The site must also be properly graded to ensure water drainage away from the foundation. Excavation is then performed to reach the required depth and dimensions for the foundation.


Footings are the area that the foundation wall is built on. They distribute the weight of the structure evenly over the soil and prevent setting or shifting. Footings are typically made of concrete and are wider than the foundation walls they support. They are poured into trenches dug into the ground and reinforced with steel rebar for added strength.


Foundation walls provide structural support to distribute the weight of the building evenly to the footings. These walls can be constructed from various materials such as poured concrete, concrete blocks, or insulated concrete forms. The type of material used depends on factors such as soil conditions, building codes, and the specific requirements of the project.



Proper waterproofing and drainage are essential for protecting the foundation from water damage. This includes applying waterproofing membranes or coatings to the exterior of the foundation walls. Adequate drainage helps prevent water from pooling around the foundation, which can cause erosion, structural damage, and moisture problems inside the building.


Concrete Foundations

The most common foundations used. Due to the strength of the concrete, it contributes to the durability and longevity of a structure. Concrete foundations are also used because they can withstand water and moisture coming from the ground.
Proper site preparation is crucial for the success of a concrete foundation. This includes excavation to the required depth and dimensions, proper compaction of the soil, and installation of any drainage systems necessary to manage groundwater.

Brick Foundations

Brick foundations have been used for centuries and can offer strength, durability, and a traditional aesthetic to a structure. Brick foundations are built using a combination of bricks, mortar, and sometimes concrete footings or piers. The bricks are laid in a pattern typically using a running bond, with mortar applied between each course to create a solid, stable foundation wall. Depending on the structural requirements and building code, some brick foundations need to be reinforced with steel rebar or wire mesh.

Block Foundation
Poured Concrete

Block Foundation


A concrete block foundation can usually bear more weight than a poured concrete foundation since concrete or cinder blocks are stacked like bricks.

The larger the building, the more likely you’ll need a stronger foundation to withstand the weight.

Concrete or cinder blocks are stacked, making them easy to transport to the site location.


Unlike poured concrete, concrete block foundations will have gaps and space between the layers and bricks since it’s not seamless.

To bond the concrete blocks, a mason will use mortar, but those gaps increase the risk of leaks.

Concrete block foundations take time since each piece has to be applied by hand.

Poured Concrete


Poured concrete is seamless and solid since it’s poured into a mold, reducing the likelihood of leaks.

It takes less time to pour concrete since it leverages machinery more than human labor to stack bricks.





Poured concrete requires specialized equipment and machinery such as bulldozers and cranes on-site to pour the concrete mix into the mold.

The wooden forms to create the mold are often large and heavy, which may require cranes to install.

Due to needing specialized machinery, poured concrete foundations typically cost more to build than concrete block foundations.
