Open cinder block wall in basement

That is odd. If that's how the mice got in then you want to fill the blocks with gravel & then smooth that over with concrete or cement. If the mice didn't enter there then "Big Gap" spray can foam would be the insulation choice & best treatment.

If you'd like to use the block voids to secure the sill of the stud wall(s) then you can screw cleats to the sill plate bottom. The cleats would be set into your concrete, cement or foam flush to the top of the blocks & the sill would be screwed to them later.

Preferably, the cleats would just be PT2x2 chunks that only snug against the basement side of the block void to hold the sill against the wall or sill with spacer blocks behind & at the wall...if the plan is to align the sill & studs to the face of the blocks & just run drywall over the blocks for a fully flat...

I would like to know how to install a steel door (already purchased and pre-hung) into my basement cinder block wall. There isn't a hole there so we'll need to cut a hole through the concrete block wall. I need to know the best way to do that. We won't have to move any outside dirt; the opening is already at ground level. Please get back to me about this, thank you.

Installing the pre-hung door will be breeze compared to cutting the opening for the door. If you had a concrete wall I would suggest that you hire a company that specializes in concrete cutting. Cutting cinder blocks will be a project but it can be handled in a weekend. The question is, where should you begin? First, get a building permit, and second, determine your ceiling height. This is important because you need to know if you have the proper height for a pre-hung. Also check to see if the cinder blocks are below ground...

Hello! This is our first time owning a home with a basement, and we have a lot to learn. I will start with the history, explain our hopes and plans for the basement, then move into the question and concerns. Feel free to skip to the question. The history and plans are here for your context if that info is helpful.

HISTORY: So, during the inspection, there was mold found in the basement of the 1953 ranch. The mold seemed to be clearly related to a bathroom leak that was also found. There was also efflorescence on the cinder block walls in several places, and it was unclear whether we had a "wet basement," but there was no sump pump, and the agent insisted that it was not. The inspector said that the assertion was plausible--that there was a "damp" problem that could be addressed with a dehumidifier. We had the leaks repaired and a very thorough basement mold remediation completed. After moving in and living there during a very rainy summer, we noticed water pooling up in...

tl,

any inside method does NOT stop water from entering a house through cracks `n other below & above ground direct-openings, gotta go 'Outside' to accomplish this. And so since an inside method doesnt stop/prevent water entry it also will not stop/prevent mold,radon gas,efflorescence,insects and does not relieve hydrostatic & lateral pressure that is against the Outside of bsmt walls.

with block walls, many times cracks that are outside are Not-visble on the inside of basement, a wall can have a hairline- 1"+ vertical/step/horizontal crack on the outside & You 'wont' see it inside.But what matters is if/when there are cracks on the...Outside of block walls, thats how & where water enters.

i`m sorry you and others have paid out the amounts you have and...have not stopped water entry.an Inside drain tile system in 'most' cases WILL keep water off the bsmt floor,but water is still entering through Outside openings.

the contractor is either 1)inexperienced,...

Buildings constructed from concrete cinder blocks offer long-term strength and durability against wind, weather, fire and pests. Unfortunately, concrete blocks also provide very little natural thermal resistance. Without insulation, cinder block walls allow unwanted cold air from the outside to enter your home, particularly in the basement. Add insulation to your basement walls to improve energy efficiency, reduce heating and cooling costs, and increase the comfort of your home.

Visit the Department of Energy website to determine how much insulation you need. Most homes require thermal resistance of R-13 on exterior basement walls, though homes in the coldest parts of the country could benefits from up to R-21. Your uninsulated concrete blocks offer only about R-1 or R-2, so subtract this from the R-value you're trying to achieve before purchasing insulation.

Install 2-by-2 wooden furring strips along the length of the cinder block wall. Place the strips perpendicular...

Poured Concrete vs. Block Walls. Poured Concrete vs.

Block Walls TIPSDEAR TIM: What's the difference between concrete block and poured concrete foundation walls? Which one is better? The lot I'm going to build upon has a seasonably high water table. Which of the wall systems would insure a dry basement?

Diane J., Redwood Falls, MNDEAR DIANE: I think it might have been easier to answer a question such as: Is a glorious sunrise more beautiful than a magnificent sunset? The truth of the matter is that both building materials - concrete block and poured concrete - can yield superior foundation walls so long as they are installed correctly. All too often builders and sub- contractors fail to realize the limitations of certain masonry materials. When this happens, foundation failures are a common occurrence. Concrete Block Is Concrete!

Though currently cold concrete, most probably wet and crammed with old utilities, your basement is a hub of potential in your home. It is only fair that we give our basements as much attention as we give other rooms in our house. If you feel your home is squeezed out, the solution to increasing the size of your home may lay, right underneath your feet. Rather than external home expansions which are by far expensive and likely to be met by zoning restrictions, remodeling the basement is a good way to expand your living area. It may save you up to 10% of construction costs per square foot. Here are tips on how to turn this underutilized space into a beautiful living space and some photos on the subject of Cinder block basement wall ideas galleries. First, start with the basic structure; The walls, Floors and Roof.

Moisture is the biggest concern to all these in the basement. Any leaks, condensation or flooding must first be tackled before any installations can be made on the...

A cinder block is an artificial building stone, obtaining by pouring and pressing a mixture of cement and slag. For this material production relatively inexpensive elements are used, which affect the final cost. In addition, it is easy to work with. Because of these qualities these stones are deservedly popular. Let's carefully examine its advantages and how to build a cinder block wall in a simple way.

Strengths and weaknesses of cinder block materials

Advantages:

easy way of installation – it is not required to ask professionals for laying, allowing you to build a structure on your own; small recessed base; long service life. Planned operating time - 100 years; relatively low product price; high reliability and durability under the condition of appropriate waterproofing; fire resistance – a wall easily withstands open fire and is not destroyed after fire; profitability - this follows from a low cost of raw materials and labor content.

Among negative...

Some construction projects call for a larger masonry block than a standard brick, but solid concrete blocks can be very expensive and very heavy. One common compromise are largely hollow masonry blocks known as cinder blocks. These are also sometimes referred to as concrete blocks, breeze blocks, or concrete masonry units (CMUs), though these terms have nuanced differences among them. Cinder blocks are generally lighter than solid concrete blocks, which makes them easier for brick masons to place in position. The hollow spaces in the blocks also provide some natural insulation or allow grout to be poured inside the rows of masonry.

Cinder blocks differ from concrete blocks in other ways besides their hollow design. Concrete blocks are made from a slurry of Portland cement and small aggregate, such as small stones or gravel. This makes them heavier and smoother than cinder blocks, which are made from a combination of Portland cement and cinders, the dusty remnants of burned...

What Makes Cinder Blocks Different?

Concrete blocks and cinder blocks, as well as split face blocks and lightweight blocks are all referred to as CMUs (concrete masonry units). CMUs are used for the construction of load-bearing foundation walls, basement walls, partition walls, exterior walls, retaining walls, and non-load bearing partition walls. Employing reinforcement bars and filling the hollow cores with grout results in strong structural walls. CMU's may look similar but there are big differences among them.

Standard (high-density) concrete blocks are made from cast concrete – Portland cement, sand, and gravel. Compared to typical structural concrete, they are made with a higher percentage of sand and a lower percentage of gravel and water for a stiffer mixture which holds its shape when removed from the block mold. The typical high-density concrete block (8 by 8 by 16 inches with two cores) weighs 36 to 42 lbs. per block.

Lower density blocks may use...

Framing your basement adds tremendous value to your home. Not only does it increase the usable square footage, but it makes the area look and feel warmer and more homey. Cinder block basement walls are actually a form of concrete and are framed identically to poured concrete basement foundation walls. If the job is performed properly, the result is walls that will not transfer moisture to the interior wall framing and sheathing. Wet wood, insulation and sheathing leads to the growth of unsightly and unhealthy mold and mildew, with eventual rot and wall failure.

Water Leaks

Check the basement walls for evidence of moisture, leaks, standing water or mold and mildew growth before framing the walls. Concrete is porous, so any moisture in the ground outside will naturally leach into the concrete and gradually dissipate throughout the wall. This accounts for the faintly musty smell in some basements. Isolated areas of darkened concrete indicate a leak, however. Leaks,...

Block walls are welcomingly cool to the touch in the summer, but in the winter, they’re cold and impersonal. Depending on the original construction, the blocks might have hollow cores or a limited amount of core filling that has minimal insulation properties. The only way to reduce thermal transfer is to add insulating material to the interior or the exterior of the wall.

Rigid Foam Insulation

The simplest and most affordable method of insulating the interior of a block wall is to install rigid foam board insulation. Available in large, three-by-five or four-by-eight sizes, the panels are lightweight and held in place with special foam-safe glue. The panels, alone, are suitable for covering the insides of garage or crawl space walls. After positioning the panels, which are easily cut with a table saw or utility knife, cover the seams with sealant tape to create an airtight vapor barrier.

Furring the Wall

If the block wall is part of a living space,...

This guy is installing blocking, most likely so he can frame a wall underneath of it.

Honestly, I had no freaking idea what the word "blocking" meant when talking about framing a wall.

When I started my basement project my friend Tom was like, "how did the blocking go?"

I played it off real cool, like "yeah, not bad, totally blocked it". But when I walked off I was thinking "what in the hell is he talking about… blocking?

I had just started framing the first room of my basement, the man office / sports room ( aka the gift wrapping room ).

The first wall was up and I as I rounded the corner to start on framing the second wall it hit me. Blocking! I needed some blocking or this wall was not going up.

Blocking for wall framing are short pieces of 2 by 4 that you install between two joists of the basement ceiling. It's not a "building code" thing and it's not optional, you'll more than likely have to install some blocking to complete your wall...

Laying out vertical rebar during concrete pour:

Several photos of formwork on this page:
Cement Block Wall Footing

Question:

First time doing this (ready-mix coming in 4 hours!). I want to get this perfect so that when I layout the block on footer I don't learn that I've screwed up and the rebars hit some blocks, and not all block cavities.

I will be using 8/8/16 block. Main wall 20' long and 2 courses high, then 4" solid block cap block, then bluestone tread cap. If my starting block is, say 4" from beginning of footer. Footing is about a foot deep:

1) First rebar should be placed where from that start line (which is where the first block will end) - some particular inches from that point to set it inside first cavity? How many inches? I have not dealt with block before.

2) I will go with the 24" on center rule, so from point suggested in answer to 1), every 24" precisely from that point, and I'll be safely in a cavity?

As I've covered extensively in my waterproofing section, basements are cool, damp places. You can't just throw any ole insulation up. You need to be aware of your options, and have a game plan going into your finishing project.

Is Rigid Foam Insulation the Right Insulation for your Basement?

Your choice really comes down to blanket insulation (aka fiberglass) or XPS. Most homes use fiberglass, but rigid foam insulation, although more costly offers a few extra features. Let's take a look.

Blanket Insulation: This is very common mainly because it is very cost effective. Usually made of fiberglass and it typically has some type of facing attached: paper, foil, or vinyl. This was the option of choice in Jason's basement and I wouldn't discourage anyone from going this route.

[NOTE from Jason: The builder for my house had pre-installed my fiberglass insulation so the choice was pretty easy for me. Living in the moderately warm climate of Virginia and not...
