For walls made with insulating concrete formwork shall be supported laterally from the top and the bottom.The thickness of concrete in the wall above.In the case of the concrete foundation wall, the wall thickness shall be greater of.For Solid Concrete block having 15 to 20 Mpa strength, the minimum wall thickness shall be between 200 to 300 mm.The specifications are summarized below for your ready reference: The Ontario Building code has stipulated building specifications for the foundation wall thickness and lateral support for concrete foundation wall and block foundation wall. This type of foundation takes a similar amount of time to build as block foundation walls and offers exceptional strength. Reinforcement bars designed as per imposed load are already installed in the footing before pouring concrete. The concrete foundation is built by pouring ready-mix concrete into formwork that has been secured on-site for the new wall construction. If your project needs a foundation with increased strength, density than poured concrete foundation is your pick. With increased load comes the need for increased strength. If properly installed and reinforced with steel rebar (typically 15mm), the block foundations are long-lasting and durable.Īnyhow, due to shoddy workmanship and improper reinforcement, some consider block foundations can be considered vulnerable. The Block foundation wall is quite easy to construct as you don’t need to install formwork. Reinforced block masonry includes installation of steel bars, also called re-bar, block-lock and fill which all connects the blocks with the concrete footing. The blocks are placed like bricks in a stretcher pattern at half bond to interlock them and give the wall stability along with strength. It is quite easy to install blocks once qualified trades are on site. The concrete block foundation is built up by using a concrete block of typical size 16 x 10 inches and is secured together with a Type S mortar mix. Anyhow, the foundation is the most important aspect of a building and one must be very careful before jumping to a conclusion.įeeling mixed-up? Don’t’ worry let’s discuss each one by one so you can choose the best for your project. ![]() In comparison between both it is difficult to beat the versatility and durability of the concrete wall foundation but surprisingly when built to code a block wall foundation offers the same stability. But to make a well-informed decision you should know the positives and negatives of both foundation systems.īoth materials are readily available in any urban areas. Well, the truth of the matter is that both foundation systems yield superior footing walls and are used widely.īoth of the systems have their pros and cons and the decision is purely yours. So, you’re looking for the highest quality of foundation for your project and are confused between a concrete poured foundation wall and concrete block wall.
