It is most important to construct a suitable foundation for a breeze block wall. Depending on the ground conditions, for a single block dividing wall, a standard 600mm x 225mm strip foundation would be suitable. Prepare the cement and lay the foundation.
How high can you build a single breeze block wall?
The maximum height for any Breeze Block wall is 6′ before professional structural engineering is needed – see an example below of a breeze block structure supported by a customized steel frame.
How do you lay breeze blocks for beginners?
How do you seal a breeze block wall?
For the best method for sealing concrete block walls and the best cinder block water barrier, read on.
- Apply a Coating Directly On the Bare Wall.
- Use a Breathable / Permeable Barrier.
- Use a Weather-Resistant Elastomeric Layer.
- Use “The Pink Stuff”
- Repair Cracks and Fill Voids First.
- Install an Air and Moisture Barrier.
Do you need foundations for a breeze block wall? – Related Questions
Do breeze blocks let water through?
What is crucial for any exterior surface, but especially the highly porous breeze blocks, is that moisture is not allowed to absorb into the substrate, which will cause damage not only to the paint work but to the material itself.
Can breeze block be left exposed?
Prolonged exposure to the weather can cause deterioration of any block type and avoiding exposure is crucial to maintaining quality of product.
What do you seal breeze blocks with?
Use LastiSeal Brick & Concrete Sealer or DryWay Water-Repellent Concrete Sealer.
What do you use to seal concrete block walls?
A silane/siloxane-based sealer is a far better option for sealing concrete blocks its blend of large and small particles, designed specifically for porous material, penetrate the surface and chemically react below the substrate to form a water-repellent barrier.
How do you waterproof an outside block wall?
Paint the cinder block wall with a thick coat of masonry waterproofing paint, pusing paint into cracks and crevices of block. A paint roller or brush made specifically for masonry is best. All to dry overnight or for a minimum of 12 hours between coats.
What is the best concrete block sealer?
- BEST OVERALL: Foundation Armor AR350 Wet Look Concrete Sealer.
- BEST BANG FOR THE BUCK: MasonryDefender Penetrating Concrete Sealer.
- BEST PENETRATING: Ghostshield Siloxa-Tek 8500 Penetrating Sealer.

Should you wet concrete blocks before laying?
Concrete block must never be wetted before or during laying a wall [2]. Good mortar is necessary to good work- manship and good end-product perform- ance. It must bond the masonry units into a strong, well-knit whole.
How do I stop water seeping through concrete blocks?
Concrete block walls can admit water to the basement through cracked mortar joints and through the porous block itself. One of the best ways to waterproof a block foundation is to install an exterior waterproofing membrane. This can be done during construction or by excavating around an existing home.
Is there a difference between concrete block and cinder block?
Consequently, cinder blocks are much lighter in weight than concrete blocks. Cinder blocks are hollow rectangle-shaped structures usually made of concrete and coal cinders which find use in construction sites. Concrete blocks often, on the other hand, are flattened constructs made of steel, wood or cement.
Why did they stop making cinder blocks?
After WWII, better technology and production habits put an end to the production of cinder. Now, manufactures use the byproducts called fly ash and slag made from coal and steel to make these blocks. These are much safer than cinder and incorporating them in to block minimizes the carbon impact today.
Why aren’t houses made of brick anymore?
The shift away from structural brick began after World War II. Mid-century consumers wanted suburban homes that looked distinct from their urban counterparts and newer building codes no longer required brick. That, meant less demand for both the material and the masons needed to install it.
Is it cheaper to pour concrete or use cinder blocks?
Is a poured concrete foundation cheaper than a block wall foundation? Usually, the cost of construction varies from place to place. But as a matter of fact, poured walls cost about 20% less than the block foundation walls.
What is a cheaper alternative to concrete?
Finding Sustainable Alternatives to Concrete
Alternatives made from recycled materials — like ferrock, ashcrete, timbercrete, and hempcrete — tend to require less carbon than concrete and also help to recycle waste materials like steel dust and chaff.
