Ways in which you can improve the drainage of your foundation

No effort, caution or alertness spent in protecting and preserving the foundation of your home is wasted. Every single minute is well worth the while. Keeping your foundation in good shape has a pretty lot to do with the way your foundation drains water. This emphasizes the non-negotiable importance of having good drainage systems. Poor foundation drainage is a buoyant guarantee of a failing foundation. When your foundation makes a habit of collecting water, doom is not far away if this is left unattended to especially when the soil starts accumulating uneven moisture. Let us, therefore, examine some ways in which we can ensure a functioning foundation drainage.

Make sure there is smooth drainage by the gutters

Gutters in our surroundings are important hence we should ensure their fluidity as well as functionality. One major responsibility of gutters is preventing stagnated pooling of water around the building. This could be from rainwater which drops of the roof to collect all about your home. For this very reason, we can see clearly we can’t afford to compromise on the efficiency of such gutters in our homes. Safety demands that the gutter disposes water a distance of ten feet (or more from the house). But this is the ideal case not necessarily the practical case, and where we have gutters not working properly, you can readily compensate for such by using catch basins to collect the water. This will go a long way in improving the drainage process.

Try to improve surface drainage

So far we have come across a lot of situations where homes can’t really boast of good surface drainage. What does this imply? Not something to smile about though most particularly when it rains. In such downpour with poor surface drainage, there is a hefty possibility of water gathering into a pool around such homes. As time piles up, this is expected to accumulate into dire foundation problems. How can you solve this? Well, one way to sneak past these ugly situations is to make changes to the slope grade about your home. Best practices stipulate that the slope angle should be directed in a way that it changes by say one inch per foot. This will significantly improve the surface drainage.

You could possibly bring in the services of a perimeter drain

This is another avenue to explore in improving foundation drainage. Typically, perimeter drains are gotten from perforated piping. Also, you can equally make perimeter drains from tile. One handsome thing about perimeter drains is how easily you can deploy them. You basically work them under the soil adjacent the footing (of your foundation). Now when water transverses the soil, it is picked up promptly in the underground drain pipe. From there it is safely transported to some other place. In other cases, it can be quickly disposed of in the sewer. This vitally contributes in the avoidance of a situation of water pooling close to the foundation. If this situation is allowed to go on unperturbed, it has the capacity to inflict damages on your foundation like cracking.

If your foundation is already having drainage issues, no tears. That is surely no big deal. Call us today let us quickly and adequately fix things. The health of your foundation can’t be overemphasized!

foundation failure

How can you tell if the foundation of your home is failing

One way to save yourself heavy costs associated with foundation failure is aptness in discovering the early signs. This can save you a huge chunk of dollars. However, you must not be a construction guru to detect cautionary signals of an impending foundation failure. There are some common indications that can give you foresight of a weakening and vulnerable foundation. Let us examine some of such factors.

foundation failure

Starting with inside your house, there are a number of situations that suggest that your foundation is falling sick and would need remedial repairs against failure. These warning signs indoor suggest below the crust, your foundation is no longer youthful, strong and healthy. Most times when your doors begin to continually jam, you should know things may no longer be alright with your foundation. This could translate into your door failing to latch as it easily does. In such situation, the problem may track far down into the foundation. Aside from this latching, there may be an appearance of cracks in your doorways or the junctions between walls and ceilings. This is the more obvious signs of a failing foundation.

In other cases, cracks may surface on your vinyl tile on top of your concrete floor. While in other cases, your window which you know to open seamlessly won’t be closing properly again while it could also stick. All these are indoor suggestive signs that your foundation is getting the kick with increasing proneness to failure.

Now if you step outside on a trivial inspection, you can see a couple of situations that would inform of the impending danger of foundation failure. If you keep a keen eye, you should be able to tell if your walls are leaning. You can deploy a level for this test. In most natural and safe situations, your walls shouldn’t be any less straight. You can investigate the straightness by measuring from each corner, that is measuring your foundation length.

A lot of times, foundation failure stems from a shifting foundation. One way to tell this is when you begin to notice slight protrusions on the concrete wall (that was poured). Such protrusion is commonly depicted in form of a bulge. This could mean bad, especially that the soil located around the perimeter of your foundation is possibly experiencing contraction and expansion. Such changes could pelt your walls with pressure.

You can take your inspection some miles some further by examining your foundation most particularly if the perimeter was poured. How hard is the concrete? Try pierce it a bit and see the response as to its toughness. If after poking the concrete, you notice damage, then the foundation is most likely corrupted as is thus more susceptible to failure. One reason why the concrete could be weakening is water. It is common among houses that the mixture was mixed with salty sand.

Lastly, you can watch out for the members of the foundation. You can tell by your inspection to your basement and examine the piers, the posts. You should also have your eye on the concrete supports. Such members are vehemently important in the durability of your bridling. Once you notice the posts are no longer straight, then your foundation could have collected some punches.

These signs should keep you alert and on your toes so that you are not taken by surprise by a failing foundation. You can always call us for an inspection of your foundation. Remember one stitch in time saves nine. Taking the proactive steps by noticing the aforementioned symptoms of an ailing foundation can save you a lot of dollars as well.

Sinkhole Problems in North Kentucky

Sinkhole Problems in North Kentucky Are Hazardous

Northern Kentucky are experiencing sinkhole problems in which are threatening the safety and health conditions of residents. Due to the crumbling sewer lines, the sinkhole problem  has risen to high priority.

Mayors at North Kentucky have begun discussion for a possible solution that has caught its attention for public safety. The committed has determined all matters are one of public safety, therefore a plan of action to repair the streets will be given the approval to move forward. A-sinkhole-damage-repair

Currently, the resident of North Kentucky were responsible for repairs, nevertheless the repairing process hasn’t been a consistent one. The service for the maintenance had been suspended due to budget cuts. When maintenance was perform, it would cost the city about $600,000 annually. The problem has gotten so bad, that there isn’t any other way to cover them.

Milwaukee City Hall’s Foundation Repair

Milwaukee City Hall’s north side requires its foundation to be fixed, and the estimated cost is between $30 million to $40 million with an estimate dates of 2016 and 2017.

The figures are preliminary, and will likely change once foundation repair consultants define they project’s plans, according to Milwaukee Department of Public Works commissioner. Other phases of the projects are also expected.

The proposed plan was introduced to the Milwaukee’s Public Works Committee back in November 2014. One of the items that was also discussed was to let foundation-repairthe 119-year-old building’s wood foundation pilings continue to deteriorate. Since 1986,  City Hall settle up to 2 inches, which supports the bell tower. If the building’s foundation isn’t fix, it will continue to settle unevenly, which will eventually lead to the building leaning, which could possibly begin to split in other places, according to Milwaukee Department of Public Works commissioner

Since they soil is in mushy conditions, City Hall is on top of about 2,500 wood piles, which are placed in a submerged manner within water, so it can be preserved. But as water levels below City Hall have fluctuated, some pilings were exposed to air, got fungal rot and decayed, leading to the settling, said Kevin Johnson, Milwaukee’s owners representative on the foundation project.

The northern side of City Hall is in worst conditions, which has been place in first priority n the proposal that was submitted back in November 2014. In order to repair the foundation in City Hall, drilling of new foundation piers will have to be done that, through other work on the foundation, will acquire the load from the wood pilings. The wood pilings will remain in place with the propose plans. The plan is to keep City Hall open as normal, which the project’s noisy, and disruptive work will be done in the evenings after business hours, Johnson said.

The budget allocated for the foundation repair is set at $1.2 million in 2014 to begin engineering and other planning for the construction, which is to start in 2016 on City Hall’s northwestern corner. The northeastern corner will begin in 2017. A project timeline hasn’t been set yet for the repairs of the remaining sections of the building.

Foundation Repair Methods

A quick online search for “foundation repair” reveals that there’s no shortage of foundation repair methods or companies proclaiming to do those repairs. In order to protect your investment, it’s important to understand the differing methods, their reliability, and make an informed decision regarding your home.

From Concrete to Steel

found its beginnings over 40 years ago in the use of concrete shoring pads to lift homes. Quickly, we found that the use of shallow piles was not a sufficient foundation repair method: adding more concrete to the footing of a home did nothing to stabilize the home long-term because the footings were still in shallow, shifting soil.

We’ve always been dedicated to research and development, employing in-house engineers. We began to learn more about the “Zone of Influence.” This refers to the area of soil that is affected seasonally by the water cycle—so shallow, shifting soil.

While we were able to achieve slightly more depth and a little more longevity by using concrete pressed piles, we still got consistent call-backs that foundations were shifting. Some companies use concrete shims today. This method provides a cheaper, short-term fix.
We knew we had to find a better, long-term foundation repair method.

The following is an examination of the four noteworthy techniques for establishment repair utilized as a part of Texas. While each has its preferences and its detriments, a one next to the other examination of Dawson’s Bell Bottom Pier technique plainly shows that it is the most solid approach to take care of a home establishment issue for all time. This technique is demonstrated and has been tried after some time. This is the same building idea used to assemble bolster sections for scaffolds and interstate bridges. What’s more, the accompanying connection will help you look at the genuine expense of establishment repair. When you get the actualities, you can be sure about your choice to trust Dawson Foundation Repair.

On the off chance that you might want a more specialized examination of each of the strategies for establishment repair, look at ADSC’s (The Association of Drilled Shaft Contractors) article Potential Heave in the Pressed Concrete and Pressed Steel Piles in Residential Foundation Construction which points of interest difficult issues with heaping techniques in the Dallas metroplex zone and how they can harm your home’s establishment – or investigate the finishes of PhD beneficiary Tom Witherspoon made in Load Capacity Testing and Analysis of Residential Underpinning Systems in Expansive Clay Environment.

Our Patented, Proven Foundation Repair Method

We resolved much of the issue when we began using hydraulically driven steel pilings. Due to the smaller diameter and higher compressive strength, the pilings could be pressed at up to 70,000 pounds of driving force.

With the introduction of a variable-length guide sleeve that prevented buckling of the pile, we finally had a foundation repair method that we could proudly put a lifetime warranty behind. With over 700,000 piles installed, we’ve had less than a 1% failure rate.

Our foundation repair methods and unique piling solutions provide the strength and stability that can only be found in the best American steel. The result is a lasting foundation and the peace of mind of knowing you’re on solid ground for the life of your home.

Giant Sink Hole in Siberia Russia

giant-sink-hole-siberia-russiaGiant Sink Holes, measuring 260 feet wide in Siberia, Russia are likely caused by melting ice or permafrost, according toUniversity of Alaska geophysicist Vladimir Romanovsky. At first many speculated that those mysterious sink holes where cause by either extra terrestrials or military weapons testing.

One unique concept of the sink holes is that it actually erupted outside, tossing dirt around the rim.  Vladimir Romanovsky explains that natural gas could have caused pressure to build as the water collected in an underground cavity, and the dirt,  was eventually expelled.

The sink may be several years old, due to the face that there are plants around the crater, but in order to get an exact age, more analysis most be conducted. More sink holes may begin to appear, as the climate continues to change.giant-sink-hole-russia

 

FOUNDATION REPAIR METHODS

There are two general classes of foundation repair; deep, and shallow. Deep repairs, sometimes referred to as underpinning, mostly involve pushing or screwing steel piers into the ground to transfer the support and lift structural elements of a foundation. Shallow repairs can be used to address slab-on-grade foundations such as floating slab floors which have settled. Soil modification is a mid-depth repair typically performed in conjunction with shallow repairs.

Deep Repairs
Deep repairs are most frequently used for lifting concentrated loads, such as footings, and for bypassing unstable layers of soil which are causing recurrent problems with a foundation. Deep foundation repairs involve transferring the your foundation’s weight to a different layer of ground than it was originally built to sit on. We install two different types of deep foundation repair systems:

Helical Piers
Helical piers are screwed into the ground to transfer the weight of your foundation to a more stable layer of soil. The weight of the structure is transferred to the deep soil by the helices (rings) of the piers.

Push (Resistance) Piers
Push piers, also called resistance piers, are pushed into the ground against the weight of your foundation. Push piers are primarily designed to be end bearing, so they are pushed into the ground until the tip of the pier runs into a layer of soil hard enough to push against to lift the foundation. Push piers can either be eccentric (mounted on the side of a footing) or concentric (installed under the center of the foundation).

Shallow Repairs
Shallow repairs are best suited for lifting non-concentrated loads such as slab floors. Both shallow foundation repair processes we perform involve injecting material immediately under the foundation concrete to fill voids and raise the foundation as required. The least appreciated of foundation repair methods, shallow repairs are often much more economical and reliable than deep repairs for slab foundations. We perform two types of shallow foundation repairs:

Foam Jacking
Foam jacking is used to raise and support slab portions of foundations, such as interior floors. High density polyurethane is injected under the foundation, where it expands and pushes the foundation back into place. We utilize foam jacking in place of slab piers.

Slab Jacking
Slab jacking is used to raise and support concrete slabs, generally outside. Slab jacking repairs settlement by injecting sand-based grout below the concrete to fill voids and raise the concrete.

Soil Modification
Soil modification changes the properties of soil to make it more suitable for bearing the weight of a foundation or structure. It can be used to stabilize sinking foundations in place, when it is determined that the disruption associated with a deep foundation repair outweighs the benefits of mechanical lifting and stabilization, or in conjunction with shallow repairs where the problematic soil is relatively shallow, and a good candidate for soil modification through a chemical grouting process such as permeation grouting.

Methods of Foundation Repair

Below is a comparison of the four major methods of foundation repair used in Texas. While each has its advantages and its disadvantages, a side-by-side comparison of Dawson’s Bell Bottom Pier method clearly demonstrates that it is the most reliable way to solve a home foundation problem permanently. This method is proven and has been tested over time. This is the same building concept used to build support columns for bridges and highway overpasses. And the following link will help you compare the true cost of foundation repair. When you get the facts, you can be confident in your decision to trust Dawson Foundation Repair.
