You have received some pretty good ideas but you need to be carefull that you don't disturb the original foundation or you could be in for some nasty surprises. Conventional concrete foundations could be underdug in sections and have new concrete perimeter added beneath with rebar to tie to coming slab. This is a dangerous undertaking for a DIY project on your old foundation.

I too suggest you consider walking headroom for normal adults. If concerns for disturbing the old foundation are preventing you from digging down to the required depth to put in a proper layer of gravel, insluation, and slab with full standing headroom (at least 7 ft) then consider not digging to the full depth all the way to the foundation but stopping short by a distance at least as deep as you dig (or as is recommended by a soils engineer.)

While drain tiles won't hurt, in my opinion if you properly grade the excavation and dig radial "ditches" pitched to fall toward the sump pump location, line these...

I was in our basement pulling up loose linoleum tiles on our basement floor.

After I pulled off the loose tiles, I started scraping the adhesive, and found the cement (or possibly some other filler type material, such as mortar) that the tiles were glued to was also pulling up. So I kept scraping, and prying up the chunks to reveal what looks like an old drain. The drain cover was embedded into the cement material I pulled up. I looked into the hole and saw nothing but dirt/clay. I've attached photos for your reference....

Not sure what to do.. it doesn't look like it connected to anything, and we don't use it as a drain (it had floor tile applied over it before we purchased the house in '96). I've attached photos for reference....

When we get heavy rains, this area of the floor would show water seeping up between the tiles... Thought maybe it was a crack in the floor. Now I know where the water was coming from.

My question is, should I just fill...

We have a long crack (25ft approx) in our concrete basement floor that seems to be getting wider. Our house was newly constructed (finished in March '08) and the crack has always been there (but now it's getting worse). We have it on "the list" for the builder and we are under warranty for 2 years (as long as the builders doesn't go out of business like so many buidlers have!


The builder has yet to reach out to us about this issue. Should we start hounding them or just fix it ourselves? If so, how? (The kids suggested "mighty putty as seen on tv" LOL!)

We're concerned that water could start seeping up, although that hasn't happened yet -but spring hasn't arrived yet.

Also, we had a very high radon level before we put the fan in the attic to pump the radon out. I imagine cracks in the basement floor are a great way to let more radon in.

Any advice?

Small houses can be frustrating to play with, especially with large families of Sims. On top of this, making additions to the house may not be practical or desired, due to lot size, desired architecture or aesthetics. Fortunately, from The Sims 2 onward, it is possible to build a basement under a house. In up-to-date versions of The Sims 3 and The Sims 4, basements can be built using a dedicated basement tool.

Unfortunately, unpatched versions of The Sims 3 and all versions of The Sims 2 lack a basement tool, but basements can still be created through the use of foundations. However, the process to construct basements is not explained in-game. As a result, some players may not understand how they are constructed. Fortunately, building basements is quite simple, and can be done to any pre-existing house on a foundation, or to any new construction.

A slab basement is a concrete basement without footings. The basement walls are built and then a concrete slab is poured. This creates a concrete slab floor that is, in reality, a floating slab. The term floating slab basement means that the concrete slab is able to move up and down as the ground moves or freezes. This is typically not an issue with a slab basement due to the slab being poured below the frost line.

One issue that often affects a slab basement negatively is water. In wet areas, water often seeps in beneath a concrete slab floor and the hydraulic pressure that it creates can move the slab up and down. This hydraulic action can crack and break the concrete slab and can also force water up around the edges of the slab. A sump pump positioned at the lowest corner of the basement will often prevent the water from damaging the slab basement.

Typically, a slab basement is poured in a structure that was previously built without a concrete basement floor. The...

Evaluate the perimeter of your house. You must ensure that the ground next to your foundation slopes away from the foundation, not towards it. Backfilled dirt around the foundation will typically settle lower than the surrounding dirt causing the ground to sink in and slope towards your house. If necessary, add dirt up against the foundation to create at least a 2" per foot (that is, a drop of 2" for each foot you move away) slope against the foundation. Make sure that the top of the dirt is at least six inches below the sill plate so that there is no ground contact which may cause certain building materials to rot in the future.


on the ground right next to your foundation, you'll have problems. Make sure your gutters are clean, and make sure your downspouts are discharging their water at least 5 feet (1.5 m) away from your foundation.


Watch out for shrubs and other plants that are too close to your foundation. Rotted roots can...

Building a home from the ground up? An exciting project, but one that requires time and research to ensure everything goes smoothly. The first decision you may be faced with is what type of foundation you want beneath your house. It’s important to be knowledgeable about the different types of foundations and what will work best with your home plans before making a decision.

Here are the pros and cons of the four types of foundation to get you started:


Homes with basements begin with a hole around 8 feet deep, ending with a concrete slab. The walls of the basement are typically formed by cinder blocks, and the entire process is done in three portions: first the beams are poured, then the walls, and finally the slab inside the walls.

This process helps keep the basement foundation waterproof. Homebuilders love the basement foundation because it adds square footage to the home, providing extra storage space if needed. Another reason why basement...

I recently posted about an unknown source of water in my basement. Today, my husband got home from work, and we decided to pull back the carpet to see if we could find the source.

We peeled the carpet back, and low and behold, there's a hole in my floor!

It's does not look like a drain hole. It's only about 1.5 inches in diameter. It has rough edges, and the edges have been painted basement floor grey, along with the rest of the basement floor.

When we shine a flashlight in there, we see foundation ants and sand. The sand is wet. There is a dark stain

The hole scares the crap out of me, because there is no fathomable reason for it to be there. It's close to an inside wall, and it's in a high point of the floor. I'm wondering if this is the source of my water problem that I experienced this past weekend.

Any ideas what this hole might be, and what it might be for?

Here are some pictures. I apologize if they are overly large, I just didn't...

Q. I have to make an unexpected repair to my poured concrete foundation. A water leak led me to remove drywall in my basement, and to my surprise, I discovered rows of holes 5/8-inch diameter in my concrete walls. Some of the holes have water dripping through them. These perfectly drilled holes are not random and are as deep as the foundation is thick. What created them? How can I patch them so they don't leak? What's the best material to use when doing concrete repair for cracks or holes like this? - Bryan R., Cincinnati

A. The holes in your foundation were not drilled; they were created by smooth steel rods that were part of the foundation-form panels used to create your concrete foundation.

These rods passed through the concrete forms. Slots at each end of the rod held a steel pin that prevented the forms from expanding outward under the enormous pressure of the liquid concrete that filled the forms to create your foundation walls. Once the concrete set and...

A basement or cellar is one or more floors of a building that are either completely or partially below the ground floor. [1] are generally used as a utility space for a building where such items as the boiler, water heater, breaker panel or fuse box, car park, and air-conditioning system are located; so also are amenities such as the electrical distribution system, and cable television distribution point. However, in cities with high property prices such as London, basements are often fitted out to a high standard and used as living space.

In British English, the word basement is used for underground floors of, for example, department stores, but the word is only used with houses when the space below their ground floor is habitable, with windows and (usually) its...

into it. What could this have been used for?

It has a

wooden door with a rubber gasket

, a


where a pipe (?) could go in, and a

smaller hole

in the floor that looks like it could have been a tiny drain. As best I can figure it was some kind of icebox or cold storage, but it seems kind of inconvenient. Also there was mid-20s oak icebox up in the kitchen, so this smaller cold storage area would seem to be a little redundant. Why built into the foundation? And what's with the pipe? It seems like it was built for a special purpose, I just can't imagine what that purpose might be.

Practical purpose in 2016?

Well, you do get to post about it on the Internet, and if you get lucky some kid who is clueless and has a Degree he has another 27 years to pay for working as an underwriter in an insurance company can go all freak and Memo some other meatloaf to terminate your Homeowner Insurance.

Then again, back when the house was being built, probably before hydraulic backhoes, somebody took the time to dig the hole and somebody spent the money to lay up a few hundred bricks. Probably the same brickie that laid up the cellar wall because the same "workmanship" shows on both.

We can be 90% certain it was laid up from outside of the hole because the inside diameter isn't big enough for a man to stand inside and lay bricks.

We can also see the bricks were not laid up in a manner to contain liquid due to the gaps.

I gotta rule out a grease trap based only on how clean the bricks are.

Looking down the hole, there appears to be a...

The Sump Pump Diagram; A Birds Eye View

UPDATED: July 24, 2017

I like to think of the sump pump diagram as an all-encompassing piece on how everything fits into place when it comes to installing a sump pump. There is a ton of information regarding sump pump maintenance, how to replace a sump pump and the like. I’ve written quite a bit about it right here on theplumbinginfo.com. However, none have attempted to answer it all. Hopefully, after you read the final word of this piece you’ll have no more questions regarding sump pump design, sump pump service or any other sump pump related questions.

Lets Tackle the Most Basic of Questions: What Does a Sump Pump Do?

The simple answer is that a sump pump is built to move unwanted water from one spot to another. Most times the water is being moved to a place where the water will drain either by gravity to a sewer designed to handle storm/ground water or some place designed to handle rainwater/ground water...

Planning and getting started

Your basement can be more than a utility and storage area. With some forethought and good techniques, you can make it as warm, comfortable and inviting as any other room in the house. But, make no mistake about it: Finishing a basement is a big job. In this article, we’ll focus on the framing and some unique problems, such as:

Finishing against cool masonry walls without creating moisture problems. Framing around obstructions like posts, heating ducts and pipes. Keeping access to valves and cleanouts. Framing and finishing a wall that’s half masonry and half wood frame. You only need basic carpentry skills for framing and one special tool—a hammer drill for concrete fasteners.

Get started by making a scale drawing of your plans to submit to your local building inspections department. Your plan should include wall dimensions, window and door sizes, and each room’s purpose (e.g., family, bedroom, etc.) along with any special features like...

I was watching 'Holmes on Homes' over the weekend on TV (for those who do not know, he's a Canadian contractor who fixes other contractors mistakes and/or negligence)....

Anywho, in the newer home that he was fixing some foundation leaks, had what he called a "cold room" in the basement. It seemed to be located outside the house footprint "proper" area and under the outside brick stairs leading to the front door. It had the same cement foundation wallson 3 sides, a cement "ceiling" and was isolated from the rest of the basement by an insulated framing wall with a door.

What is the purpose of these "cold rooms"? There was not anything in there to give me a...

I was recently asked what type of foundation is best for a small cabin. Unfortunately there really is not one right answer.

What are the typical foundation types?

Basement Crawlspace Slab on grade Pier and Beam Skids Wheels

Each foundation type has its pros and cons and which will be the best for any situation will be based on many things, such as:

Your land Your budget. Your needs. Your soil conditions

Let’s look at each type and see if we can determine where they might be best used.


Basements are usually the most expensive solution but also offer extra area for storage and mechanical equipment. They are best used in well-drained soil conditions or where you have enough slope in a lot to “drain to daylight”. A leaky basement is worse than no basement at all. Also basements generally require good access for construction equipment to excavate. Basements also are economical when you have a decent slope for a walkout basement or where...

A better footing drain
When you bury your work forever, it had better work for a long time. Sand, gravel, and filter fabric keep drain pipes flowing free.

Footing-drain problems are expensive to fix

Building codes require perimeter drains around the outside of basement footings. They are not difficult to install properly before the foundation has been backfilled, but they are costly and disruptive to put in after the fact.

As long as you're going to protect the bottom of the foundation of a house from water, it's worth doing right.

See below for:

Key Materials

PIPE TYPES. Rigid PVC drainpipe (top) is crush-resistant but a little harder to work with than flexible pipe (bottom). PVC comes in 10-foot lengths, is crush-resistant to 3,000 pounds, and costs about $0.65 per foot. Flexible plastic comes in long rolls, but big rocks can crush it during backfill. Cost: $0.40...
