DIY Home Inspection - how to identify and control the problem of the Foundation

The foundation walls are connected to the top of the foundation. The purpose of a foundation to support the weight of the structure of the house to be down by the Foundation for the foundation.

Regardless of their construction (cement, bricks, cement blocks, etc.), foundation walls crack, due to lateral force, settling, heaving or uneven load (more weight than designed on a specific part of the foundation) of the foundation walls . natural forces such as earthtremors could also assist in earthquake regions.

To begin your control by using a pad and pencil for the foundation exterior. Take notes of cracks and their locations. When inside the lower level, you want to try to get back to it on the inside. If the crack goes completely through the foundation can be a red flag. Small holes that pass through the back wall are common and nothing to worry about, these can be caused by the withdrawal ofthe concrete or mortar joints.

A crack has sometimes found a similar type of crack on a wall opposite of the foundation. Similar cracks on opposite walls may have the same cause, except the horizontal cracking caused by a lateral force.

Types of Cracking
Vertical and 45 degrees Cracking is usually caused by settlement and heaving. Horizontal cracking is usually caused by lateral pressure on the foundation, as the hydrostatic pressure (lateral force).Cracks, not entirely through the wall and no signs of repression are not normally a structural defect. Isolated vertical slits not extending beyond the lower edge of the foundation wall are usually cracks. They are caused by the contraction of concrete during curing.

Causes of Cracking horizontal
The foundation should act as a retaining wall, resistance to lateral pressure of soil on the outside of the basement or crawlspace. If the foundation is not enough lateral support, the walls to bend inwards and create horizontal crack. Some of the causes of foundation walls that are too thin or not (or not enough), increasing as a reinforcement in the concrete foundation, filling the bases too quickly before the foundation of healing has a chance to complete or backward during filling and large stones or lumps of frozen soil has been dumped at the Foundation.

Causes ofDein Ende Foundations
Dein Ende cracks in the foundations of brick, block or stone (not concrete), usually in the form of cracking a step called "step." Get cracking usually follow the mortar joints in these materials.

In concrete foundations, the tears are on the rise generally vertical and are wider at the top of the slot at the base.

Some parts of the country have vast lands, which increase in size as they absorb water, thus increasingcracks. Humidity added a vast land area, for example by a sudden descent, will dramatically change the volume of soil and cause serious problems panting and structural damage in some cases. Upon exhaustion of the vast land, can also lead to an effect of contraction pulling on the foundation. The method of prevention is to maintain soil moisture, keeping the soil as dry as possible by the Foundation. This can be achieved by proper grading around the perimeter.

CauseLiquidation of the Foundation
Settlement of the soil under the foundation is usually the cause of cracks in the walls of the foundation settlement. Cracks caused by settling cracks appear due to rolling, with the exception of the crack is wider at the bottom of the crack.

If a crack is active crack can still move (increasing, etc.) to identify an active crack, sharp edges, clean the inside of the crack, sometimes with pieces of concrete still the gap. Old cracksall dust, dirt, paint and insect parts in the slot.

To determine the severity of a failure or its cause, can be evaluated by a geotechnical engineer. Large cracks 3 / 8 "in width must be carefully studied. Cracks can be measured by the engineer, to determine whether it is moving or if it is stable. Many times, home inspectors use the services of an engineer, to ensure the foundation is the sound. as a former home inspector, I have often surprised to find cracks questionablewere sound without a worry. I've always been glad that was reviewed in the interest of the client or in your case.

What to look inside the structure of the house:

Doors and windows are locked and the displacement (gaps)
Foundation settlement can lead to doors and windows are aligned. This can be seen by looking at the edges of windows or doors, close them. For larger holes on one side than the other. This can help determine where the settlement isoccur.

Cracks in walls
Settlement will usually cause wall cracks. Settlement cracks are larger on one side than the other. Suitable wall cracking can also be caused by the expanding and contracting house through its seasons. If there is no evidence of defects in the foundation of the wall and there is no fracture, probably caused by the latter.

Slope or grade levels.
I learned during my career that most home inspectionpeople do not realize slope less than 1 / 8 "per foot plants. 3 / 16" per foot of plant is obvious to most people. A family lives in a bigger house for a long period may not even notice severe acute. We tend to adapt to gradually decline over time.

If in doubt, use a level to determine if the surface is flat. Increase floor should be recorded for future reference in the control.

Unless the renewal is expected to substantially tilted or extended, would be the best repairto stabilize the foundations. King extended leveling an old house can be more than expected damage to interior walls, ceilings, doors, windows and cabinets.

If the property is stabilized and the future movement is unlikely, buyers often agree to uneven floors.

Ignoring Foundation Repair

Foundation repair is not something most of us like to think about. We tend to ignore it and hope that fixes itself. Foundation problems can be a stressful, potentially costly endeavor, filled with uncertainty, particularly if not done under the direction of a professional contractor or foundation engineer.

Foundation Repair is needed when your foundation begins to settle or move laterally. This can be caused by building on expansive clay, compressible or improperly compacted fill soils, or improper maintenance around foundations.

Foundation repairs aren't easily performed, so you cannot sit back and hope for the best. You must do your homework to find the best foundation repair contractor for the job. As usual, the lowest price is not always the best way to go. If you choose to make your final decision based on price, be prepared to be disappointed. Quality repairs take specialized equipment and specially trained people to perform the work.

Needed foundation repair work can not be ignored. The traditional answer to foundation repair has been to erect piers to jack up the foundation and raise it off the expansive clay soil. The piers must be installed through the expansive or weak soils to stabilize the structure. Foundation repair can be the most expensive repair that you will make to a property. There are four major categories for this type of piering - steel push piers, helical piers, micro piles and concrete piles. Each of these have their benefits and logical applications.

Steel push piers are hydraulically driven piers that use the weight of the structure to drive steel pier material through the soil until they reach a load bearing stratum for support. Once the pier material is driven, individual hydraulic cylinders are attached to each pier and the structure is either stabilized or lifted using a hydraulic manifold system. Steel push piers are best suited for basements, crawl spaces or other heavy structures.

Helical piers are similar to push piers except they are screwed through the soil and use a steel plate, flight, to support the pile within layers of good soil. These piles must be monitored very closely upon installation to achieve their intended depths. Once an adequate depth is achieved, once again, a hydraulic manifold lifting system is installed to lift or stabilize the structure. These helical piers are ideally suited to light weight structures that only need a small lift or stabilization.

Micro piles are hydraulically driven hollow steel piers that are filled with grout during installation or immediately upon completion. The hollow bar serves not only as structural steel but also as a means inject the grout. These high capacity piers use the same type of manifold lifting system as steel push piers and helical piers. While these piles have very large capacities and can be installed in soils that other piles cannot be installed in, they also require much more equipment for installation which make them more expensive to install. They are best suited for very heavy structures sitting upon poor soils laden with cobbles, boulders and trash.

Concrete piers are piers that use a drilled hole filled with concrete that rely on skin friction for support. They are drilled or dug into the soil, usually beyond the active soils, and then filled with concrete. Once the concrete has hardened, a shimming system is usually employed to support the structure. These piers are not only messy but take much longer to complete.

Foundation repair is critical to address as soon as you suspect a problem. For starters, the sooner you fix a failing foundation, the less damage it will cause. Due to the complexity of foundation repairs the best advice is to hire an engineer followed by a trained foundation repair contractor. These professionals will make sure that your home is fixed correctly and permanently. Do not ignore your foundation problems have them fixed by the pros.

When to Use Basement Waterproofing Products For Foundation Repairs

Basement waterproofing repairs constitute some of the most expensive professional services you can incur for your home. Every year, homeowners across the country shell out thousands of dollars to have basement waterproofing companies excavate around their foundation, repair footer drains, and service their basement walls. In many cases, however, you might be able to sidestep the high prices of professional contractors and do your own basement wall repair by purchasing a few inexpensive products.

The level of damage to your foundation walls has a lot to do with what kind of repair work you will need to have done. While many waterproofing companies offer free estimates on work, you can't always rely on them to tell whether you really need professional help or if you could just complete the work yourself.

The interior basement waterproofing products that you should consider for doing your own repair work include waterproofing sealant, paint and crack fillers. If your walls are showing a bit of dampness and small cracks, but you don't have the budget to pay for professional waterproofing, then a temporary fix can help.

Make sure that you seal all visible cracks using high-grade sealant, and clean the basement wall thoroughly before applying waterproofing paint. Make sure that the paint you choose also includes an anti-mildew and mold agent. While this will only fix your foundation walls on the inside and provides only a temporary fix, it will allow you to make your basement more livable and aesthetically pleasing.

One word of warning: these kind of damages definitely indicate a larger problem with your foundation drainage system, and you should call a professional contractor when your budget can afford the expense. Basement waterproofing products are only a temporary solution, but to really fix your foundation problems, you'll need the help of local professionals.

What Can Be Done About That Foundation Crack?

The importance of fixing basement foundation cracks as soon as they are noticed cannot be stressed enough. This will prevent further problems like leakage of water. The crack will grow in size and become less controllable if repairs are not performed immediately. There are methods to fix and prevent this occurrence in your basement without extensive or expensive work.

If there is a leak, then polyurethane foam will help to seal the crack and prevent water from leaking in. This material is for repairs that are not related to the structure of the premise. Polyurethane foam is elastomeric, therefore, the material can enter any size crack, even the minimal ones. A major benefit to using this sealant is that it sets quickly so liquid cannot enter while the crack is injected.

Epoxy is used in areas with structural damage. The material is slow setting and takes several hours to completely change to hard form. While it is in its original form, the sealant may drain from the crack. This may be the case if any walls have separated from the building's foundation. When repairing cracks, using caulk or cement is not a good choice. This will not stop the liquid from leaking behind the caulk. The material used to seal the crack will not remain and will wear off during the cold weather when frozen.

Water must have a way to drain so a drain system is important. Interior tiles and exterior tiles are the two types used for basement waterproofing. The tiles have a pipe that has holes to let the accumulate of liquid out. It is housed by a trench and then enclosed under gravel. Water from the pipes flows into a sump pump and is stopped from harming the building's structure and foundation. The tiles vary in shape and the material they are made from. They are available in rectangular, round, or square.

Interior drain tiles can be installed on top of the concrete, in the concrete slab, or under it. The most popular placement selection is under the concrete by creating a trench for the pipe and covering it. Exterior drain tiles are put in during the building process. They are installed outside of the building to send the water collected away from the foundation and into the ground outside.

Though this method is more expensive, this is a quality method to eliminating water leakage. The area that is located near the foundation is dug up and then rebuilt. This type of drain is located by the footing of the foundation and requires a sump pump. Water should be removed slowly from the basement to prevent foundation and structure harm.

If the water is removed fast, the floor and walls may break. You must balance both the outside and inside pressure to prevent indoor pressure from exceeding the outdoor pressure. The water should be eliminated one foot at a time after the outdoor water level has receded. Repeat until all of the water is out.

Why Choose a Pier and Beam Foundation?

Building a home is an exciting venture. Homeowners get to choose wall coverings, flooring materials, up-to-date appliances, room size variances, and windows and doors. But, what most homeowners do not realize is that building a home starts from the ground up, from the foundation.

The most important step to building a new home is choosing the most efficient and safe foundation for your property location. Researching foundation bases is essential in securing the structure of your new home. Some contractors are knowledgeable about foundations and will help you choose which is best for your home. But, there are many who will pour a foundation of their choosing without discussing the choice with you, the homeowner.

Two foundation choices that a new homeowner should be aware of are slab-on-grade foundations and pier and beam foundations. The two are quite different when it comes to construction, cost, and longevity.

Slab-on-grade foundations are constructed with reinforced concrete and are usually shallow, quickly built, and inexpensive. For a builder that doesn't have to live in the homes that he builds, slab foundations are a dream. Slab foundations are used with homes that do not have basements. A major disadvantage to slab-on-grade foundations is that they are not resistant to seasonal movement changes and moisture disbursement due to root growth. In other words, slab foundations are not a long-term option for homes in North Texas. Another disadvantage is that generally all piping is placed under the slab foundation causing a very costly procedure should a water pipe burst.

Pier and beam foundations, on the other hand, rate a few steps above a slab-on-grade foundation. Pier and beam foundations incorporate a crawl space (usually at least 18 inches) beneath the home and footings filled with concrete to support the slab. This type of foundation is not considered a time saver, but it is safer and more convenient. The crawl space allows access to heating and plumbing utilities without having to break through the concrete slab. The piers mean foundations are less susceptible to damage due to ground shifting, a problem many North Texas homes with slab foundations experience. If extreme ground shifting does occur, the foundation is easily adjusted, a process that is much less expensive than slab foundation repairs, a process most homes in North Texas will have to undergo.

Since pier and beam foundations leave homeowners walking on a suspended wood platform, they are much easier on the body's joints. Pier and beam foundations are preferred by back pain suffers over slab foundations.

Pier and beam foundations are generally used for homes built in the Northern part of the country because the climate consists of the freeze and thaw conditions. This condition requires that the foundation be built deeply in to the ground. The safety feature here is that deep foundations are very rarely affected by climate changes. But, the shifting grounds of North Texas make pier and beam foundations the best, longest-lasting choice for foundations in the area.

Monster Constructors is professionally known for laying pier and beam foundations in the Dallas/Fort Worth Metroplex. They will test the ground on which the home is to be built to decipher the best foundation for that particular area.

Water Or Moisture in Your Basement? How to Waterproof Your Foundation

Recently we received a call from a potential customer that had water in her basement. She found our company through a search on the Internet and mentioned our approach to waterproofing foundations seemed like more of a permanent solution than some of our competitors which offered foundation waterproofing solutions working from the inside, something that really is more of a temporary fix and it prompted me to write this article to explain the correct approach to waterproofing your foundation.

As a homeowner, your biggest investment is probably your house, but not only is it an investment, it is your home, a place where you keep your family safe, secure, and warm and too often we come across homes that have moisture or water in their crawlspace or basement, this can lead to all sorts of issues from damage to health issues related to mold.

Thankfully, there are permanent solutions to waterproofing your foundation. There is a saying "if your drainage is a mess, call us". This is really where it all starts, your drainage. Since we are based in the soggy and water saturated area of Seattle and the Greater Puget Sound we have seen these issues come up numerous times, even after another waterproofing contractor has completed their supposed fixes working from the inside, but we know the problems stem from the outside.

It's much like the analogy of a doctor giving you medicine to hide a problem, rather than diagnose what the problem is, and typically our diagnosis results in resolving the drainage issue, rather than offering temporary fixes to hide the problem.

Here is typically what your solution should entail for waterproofing your home and foundation. A house that is built on a foundation should always have what is called footing drains that may or may not be tied into your gutter drains surrounding the perimeter of your house. If you have water in your basement, it is often times because of failed footing drains if there are any footing drains, so what is needed to be done is to first excavate around the perimeter of your foundation.

At this point it is important to excavate to the base of the foundation and put a waterproofing membrane around the entire foundation, it is important to note, that some contractors may put an alternative material, one that does not create a true waterproofing membrane. After the membrane is applied, it is time to install your new footing drains using perforated pipe, you can ask your local supplier for detailed instructions. Make sure all your footing drains are sloped in the direction to your discharge point away from the house, possibly even to a drywell.

You have now completed a two part waterproofing system for your house and at this point water should not be penetrating your house, but you are not quite finished. You still need to order and fill trench with drain rock, cover with filter fabric, and backfill before you are totally finished.

I understand visualizing the process can be daunting, especially if you have decks, patios, driveways, landscaping, etc. around your foundation, that's why it is best to always use a qualified waterproofing contractor in your area. Just make sure they use an approach similar to the solutions we recommended in this article, one that offers a permanent solution with a 100% lifetime guarantee.
