Which is Best? Poured Concrete or Block Foundation Walls

Types of Masonry Foundations Their Construction and Uses – Is Masonry Foundation Concrre

All too often builders and sub-contractors fail to realize the limitations of certain masonry materials. The only difference between the two finished products s the size of the gravel. A concrete block may have gravel no larger than the size of a standard green pea or a dried raisin. A poured wall doesn’t have joints like a block wall so it is easier to waterproof. Both types can also be reinforced with steel rebar. One benefit of a concrete block wall is that the concrete is already solid at time of construction. Some are built on a flat, concrete slab, which provides both a base for the structure and serves as the bottom floor of the house.

They are hollow when laid up; steel reinforcing bar is added and the hollows are often filled with concrete. Fibre-reinforced concrete has better structural integrity, reducing the need to use steel rebar in your build. It is often used in sustainable construction as it helps to protect water quality and limit water waste, ensuring a low-impact development. It also offers high thermal qualities. Screed can be difficult to lay, but our team are on hand to offer you advice and talk you through the process to ensure you get the best results.

Usually, a screed of this type will be laid at around 65mm thick for lightly loaded floors, but a suggested thickness of 75mm may be more appropriate for heavy duty use floors.

Underfloor heating screed is usually laid at a thickness of between 65mm and 75mm, but if you’re unsure, check your project requirements with an expert to be sure you get the right solution.

The gravel is then covered with six inches of straw or a sheet of tar paper before dirt is placed over it. The water that flows through the soil and makes it to the pipe is then drained to daylight if the house is built on a sloping lot.

I vacuum / brush it off and it re-appears. I just witnessed the sump pump running you could hear the water going out of the house overhead and 3 minutes later the water would literally pour back in the crack!

Do you think the water entered from the outside water line or from under the cove joint and worked its way up. How do you tie in a new straight wall to a bowed at the corner?

I mistaken that it won’t be as strong as a solid wall? The basement is rectangular with a 7′ ceiling. Half of the basement wall is a full 7′ tall. The other half has been dug out, leaving a 2′ knee wall on a 5′ tall dirt ledge. A poorly formed sister wall was put in some time in the past to hold the dirt ledge in place. Replacing the wall exceeds the value of the house. Many engineers have told me that the sister wall is not load bearing and therefore does not need a footing under it. Is it possible to hand-stack concrete and fix this wall? Any expert advise would be appreciated. I am looking to start building a house with a full basement and the info you have supplied is a great help. I would just hate to build a basement and then have to worry about it flooding. Your advice would be appreciated. I know that the concrete needs light wetting while curing. The contractor is preparing to pour concrete. Because there has been delay due to weather (rain) there is now dirt that has built up over the concrete seating for the posts.

The basement wall is 9 or 10 feet tall. Sheetrock, glass shower doors close perfectly, doors and windows close perfectly. We think the wall always leaned, was constructed that way. Look forward to your opinion on our second opinion. I used this dirt, to fill in the gaps in the concrete block? One is to fill it in as each layer is cemented in place and tamp it down solid. One made with a solid bottom for the holes with no rebar and one build with a hole in the middle for the ones with rebar.

The dirt may draw moisture and freeze at points above the frost line causing block failure. Since this is not an excepted building practice it wouldn’t get through inspection. My property is 38 inches above the grade of the surrounding area and four rows of the fence block retain dirt. When it rains, water soaks the soil and eventually loosens the stucco on the outside. I had to move a doorway in the basement and cut the concrete out to find no horizontal or vertical rebar in it. Water’s damn heavy so you better get an engineering stamp on your flood plank plans at the driveway! Each approximately 300 feet across the south perimeter with gravel road access. The only way for me to give you an accurate answer is on the phone.
