When it comes to block foundations, how long do they last?
If constructed properly, poured concrete block footings and slab foundations should endure a lifetime, 80 to 100 years or more.

How do you distinguish between cinder bricks and concrete blocks?
A concrete block is heavier because it includes stone or sand. The tensile strength of cinder blocks is insufficient to bear pressure. Concrete is a tough, long-lasting material. Many construction rules forbid the use of cinder blocks because they are not particularly flexible.

Because concrete blocks are porous, they must be treated, coated, or covered to prevent moisture from soaking through.

Water trapped within the block ultimately seeps through the foundation. It’s worth noting that concrete blocks are porous by nature. It absorbs moisture quickly, which may lead to mold growth. We can either stop the water from getting in on the outside (Exterior Waterproofing) or catch it on the inside (Interior Waterproofing) (Interior Waterproofing).
What is the finest concrete waterproofing?
