Screw piles are an incredibly durable, reliable form of foundation, and there is no definitive answer as to how long they will last. The longevity of screw piles depends on a variety of factors, including the materials they are made of, the environment they are used in, and the amount of maintenance they receive.
Generally speaking, screw piles made from galvanized steel can last up to 75 years or more with proper maintenance. Screw piles made from other materials, such as wood or aluminum, typically last around 10-15 years.
The environment the pile is in will also have an impact on its lifespan; for instance, screw piles in marine or wet environments will last significantly less time without proper maintenance. As such, it is important to consider all of these factors when installing and maintaining screw piles.
With proper installation and regular maintenance, screw piles can provide a robust, reliable foundation for many years to come.
How much weight can a screw pile hold?
The amount of weight a screw pile can hold will depend on a number of factors, including its design and reinforcement, soil composition, and environmental conditions. Generally speaking, quality screw piles can provide tensile and compressive ratings of up to 70,000 lbs and tensile and compressive ratings of up to 40,000 lbs, respectively.
That said, soil conditions, including the type and strength of soil, the moisture content, and compaction, ultimately determine the design of the screw pile and will therefore affect the maximum load capacity.
For example, in more cohesive soils, more reinforcement is needed and the pile will be slightly longer and deeper, which will reduce the potential load capacity. In addition, the depth of installation will also affect the load capacity, with deeper piles typically providing greater capacity.
Extreme loads, such as seismic and vibratory can also reduce capacity. Despite these factors, quality screw piles generally have load capacities that exceed alternate foundation types, such as concrete or steel piles, making them a popular choice for many applications.
Are screw piles as good as concrete piles?
The answer to this question will depend on the specific application and the requirements of the job. Generally speaking, screw piles can be just as reliable and effective as concrete piles when used for typical residential and light commercial construction applications.
Screw piles typically provide the same bearing capacity, stability, and resistance to lateral loads as a concrete pile of the same size and length. They install quickly, are highly adjustable, and require minimal disruption to the site.
Screw piles can be very cost-effective, especially when compared to concrete piles which must be cast in place.
When compared to concrete piles, screw piles also offer several unique advantages. Screw piles can be installed in areas with limited access and can be driven into the ground using a much smaller machine than concrete requires.
This makes them ideal for projects where access to the job site may be limited, or where precision placement is important. In addition, they can be installed without the mess or disruption of concrete or cement, and the installation process is much faster.
Ultimately, whether screw piles or concrete piles are the better option for a given job will depend on the specific application requirements, budget, and timelines. However, for many projects, screw piles can be a reliable, cost-effective option that offers several unique advantages over concrete piles.
Do screw piles settle?
Yes, screw piles do settle. This type of foundation involves driving piles of metal into the desired position until they reach an appropriate depth, usually bearing on rock or a bed of hard, dense soil.
The idea is to drive them far enough so that the foundation will rest on these piles instead of the soil beneath.
Although Screw Piles provide a high level of stability, they still may settle over time; however, the amount of settlement is usually quite minimal. Settlement typically occurs due to the foundation pushing on the soil beneath it, causing it to slowly compress and lower over time, or when groundwater levels change.
These issues can be prevented by ensuring the screw piles are driven to a sufficient depth and that the piles are properly backfilled. In some cases, the homeowner or builder may also opt for a foundation or pier installation instead, which does not require the use of screw piles.
However, this option can be much more expensive and should be considered carefully.
Do screw piles work in sand?
Yes, screw piles are a great solution when looking to establish a stable, secure foundation in sand. Unlike concrete piles, screw piles are much easier to install and much less disruptive. due to the fact they can be installed with minimal vibration, cutting and disruption to landscape.
In sandy soil, the installation process creates many positive benefits. As the pile is screwed into the ground, it compacts the soil around it and displaces any loose sand that is under the pile, creating a strong foundation.
As the pile is screwed deeper into the ground, it displaces the grains of sand on top of it, forcing them both downwards to compact. This creates a stable foundation that is able to cope with extreme loads and forces from a variety of different weather conditions.
How long does it take to install screw piles?
The installation of screw piles usually takes anywhere between 15 minutes to an hour, depending on a few factors. If the screws must be drilled into hard-to-reach places, the installation time will be longer as more set ups must be used.
Additionally, the size of the pile being installed and any existing obstructions can contribute to the installation time. Once the screw pile is in place, securing it in its final location may add an extra 15 minutes if specialized equipment must be used.
If minor adjustments such as setting the foundations precise level or dealing with the soil layers need to be made, the installation time can increase even further.
Can screw piles be installed in frozen ground?
Yes, screw piles can be installed in frozen ground. This is because screw piles are self-tapping and provide a unique advantage for installation in frozen ground. The self-tapping nature of a screw pile allows it to be forced into the ground to create a strong base in the frozen ground.
The helical blades on the piles help to keep it in the ground and to provide a strong foundation even in the coldest temperatures. Additionally, the steel shaft of the screw pile can absorb the extra force of the installation and add additional support to the structure.
In order to install screw piles in the frozen ground, it is important to contact a professional to ensure that the installation is done correctly and that the structure can be safely supported.
How much are helical piles for decks?
The cost of helical piles for decks can vary greatly depending on a few different factors. The size and number of piles needed is the first factor that will impact the total cost, as well as the load the piles will need to bear.
The grade and material of the helical piles will also factor into the cost, as steel or composite helical piles may be much more expensive than timber or timber-laminated piles. In general, helical piles for decks can range in cost from several hundred dollars to several thousand dollars or more depending on these factors.
Installation costs should also be factored into the total cost, as they can range from several hundred dollars to around a thousand dollars or more depending on the complexity of the job.
Are helical piers better than concrete?
That really depends on the specific application. Helical piers are typically preferred in more sensitive areas where deeper foundations would be more disruptive and they also allow for greater accuracy and quicker installation.
Concrete tends to be cheaper and can provide a heavier load capacity, but it also requires far more intensive labor to install and lack the precision of helical piers. Factors such as cost, soil type, structure size, and location should all be taken into consideration when deciding between the two.
Ultimately, it depends on the specific job, so it’s important to consult a professional to determine the best solution.
How many helical piers do I need?
The number of helical piers needed will depend on the size and weight of your structure, as well as the intended use. In order to determine how many helical piers you need, you should consult with an engineer or soil specialist who can run soil tests and analyze the ground around the area where you are looking to install the helical piers.
It is important to note that the depth and number of helical piers must be adequate for the intended use and for the size of the structure being supported. Generally, helical piers are installed at a depth of 2 to 8 feet below the surface.
The exact number of helical piers needed will also vary by the soil type and the soil load that is being supported.
Which is better concrete or steel piers?
The answer to this question depends on the purpose of the piers and the specific situation. Generally, concrete piers provide more stability than steel piers and are more cost-effective in the long run.
Concrete piers are a permanent solution to support a structure because they are less susceptible to rot, insect damage and other environmental conditions than steel. The material also has good vibration absorption and insulation capabilities so it is often used for vibration-sensitive projects.
Concrete piers are also more aesthetically pleasing than steel piers, as they can be easily camouflaged and painted to blend into background. However, concrete is heavier than steel so concrete piers need additional foundation work, which increases installation costs.
Concrete piers also give off a heavy carbon footprint since the curing process requires a lot of energy.
On the other hand, steel piers are more lightweight and give off a much lower carbon footprint than concrete. They are also more cost-effective as a smaller foundation can be used. Steel piers also have a higher corrosion resistance than concrete, making them a better choice for marine structures.
Overall, the choice of concrete or steel piers depends on the specific project, the budget and the aesthetic preferences of the owner. Both types of piers offer strong foundation support in diverse conditions, so the correct choice is the one that best fits the project needs.
Can you build a house on helical piles?
Yes, you can build a house on helical piles. Also known as “screw piles” and “screwpiles,” helical piles are deep foundation solutions that are used to provide foundational support for new homes, bridges, and other structures.
Helical piles consist of steel shafts with helix plates welded to them. This type of pile provides a strong and stable foundation that can handle large loads and uneven terrain. Additionally, they can often be installed and loaded quickly and are a cost-effective solution.
The installation and design of helical piles depends greatly on the soil conditions present at the site. An experienced engineer should be consulted in order to find the best solution for any given project.
In addition to proper installation and design, regular checking and maintenance of the helical piles is recommended in order to ensure the safety and stability of the foundation. The piles should be examined for any signs of corrosion or potential structural damage.
Any necessary adjustments or repairs should be done as soon as possible to prevent problems from escalating.
Overall, helical piles offer a great solution for foundation support in both residential and commercial construction projects. They provide a secure base that can handle heavy loads and uneven terrain, while also being cost-effective and relatively easy to install and maintain.
An experienced engineer should be contacted in order to ensure that the helical piles are designed and installed properly. With the right preparation and regular maintenance, helical piles provide a strong and reliable foundation for any house or structure.
How deep should piers be?
The depth of piers depends on a few factors, including the purpose the pier serves, the local soil and water conditions, and the climate where the pier is located. Generally, the depth of piers should be determined by the local tide, the purpose of the pier, and the expected wave motion.
For a pier used as a dock or mooring, the pier should be deep enough to accommodate boats at high tide while also providing an adequate clearance from the bottom. In areas with a harsh climate with large waves, such as exposed coastal areas, the pier should be deeper than in areas with a milder climate with smaller waves.
In areas with shallow soil and local water conditions, piers should be deeper to ensure the structure is firm enough to support the weight of the pier, increase stability, and prevent damage. Additionally, any pier should be strong enough to withstand anticipated wind and wave loadings.
Are screw piles any good?
Yes, screw piles are a great option for certain situations. They are a type of deep foundation that is driven into the ground using a drill, and use helical blades as a type of anchor. They are especially useful for unstable ground conditions, where traditional poured concrete foundations may not be able to hold.
They are also a good option for areas with restricted access, as installation does not require a large excavation in the ground. Screw piles are more affordable than traditional foundations, and there is less risk of structural damage due to inaccurate leveling or poor construction.
Additionally, they are low maintenance, and will last for many years with minimal maintenance.
Can hemorrhoids be permanently removed?
Yes, hemorrhoids can be permanently removed. For minor external hemorrhoids, removal can be done using simple methods such as rubber band ligation, sclerotherapy, or infrared coagulation. For more severe cases, surgery may be necessary to remove the hemorrhoids.
Surgery may include a procedure called hemorrhoidectomy, in which the hemorrhoid is physically removed. Additionally, laser treatments can be used to seal the veins that are causing the hemorrhoids and to destroy the hemorrhoid itself.
In more severe cases, more advanced surgeries may be needed, such as stapled hemorrhoidopexy, where the hemorrhoid is stapled back into place.
Generally speaking, the goal of these procedures is to reduce symptoms and to prevent the recurrence of hemorrhoids. However, it is important to remember that there are potential complications associated with these procedures.
It is important to discuss with your doctor which option would be best for you and to weigh the potential risks and benefits.
Can hemorrhoids be removed without surgery?
Yes, hemorrhoids can be removed without surgery. Many people seek non-surgical treatment for their hemorrhoids because it is often a less invasive and less expensive option. Non-surgical treatments for hemorrhoids can include dietary changes, exercises, creams, ointments, and suppositories.
Dietary changes can include increasing fiber intake and adding more fruits and vegetables to the diet to avoid constipation. Exercises such as Kegels can help strengthen the pelvic floor muscles and increase blood flow to the rectal area to help reduce hemorrhoids.
Creams, ointments, and suppositories may provide temporary relief from the symptoms of hemorrhoids, although they do not address the underlying causes. For those seeking additional help, there are some alternative treatments such as acupuncture and herbal remedies that are worth exploring.
Ultimately, the best way to get rid of hemorrhoids is to determine the underlying cause and to treat it – and non-surgical treatments may be a great option for many people seeking relief.
What size hemorrhoids need surgery?
The decision to surgically treat hemorrhoids is typically based on the size, location, and symptoms associated with them. Surgery is recommended for large external hemorrhoids or internal hemorrhoids that are prolapsing and/or bleeding.
In general, if internal hemorrhoids are the size of a grape or larger, they likely will require surgical removal. In addition, if external hemorrhoids are causing significant discomfort, particularly if accompanied with excessive bleeding, surgery may be recommended.
Surgery for hemorrhoids can be done with a variety of techniques. The type of surgery used depends on the size and location of the hemorrhoids, as well as the patient’s preferences. These techniques include stapling, laser and infrared coagulation, and hemorrhoidectomy, which involves the complete removal of the hemorrhoid.
How do you get rid of piles without surgery?
If you have piles (hemorrhoids) there are a variety of non-surgical treatments you may find helpful.
Start by eating fiber-rich foods such as beans, oats, wheat, and barley. Aim to get at least 30g of fiber a day, plus 8-12 glasses of water to soften stools. You should also reduce your intake of caffeine and alcohol, which can lead to dehydration.
It’s also important to move around and exercise, which can help prevent or reduce the symptoms of piles. Setting up a daily exercise routine, even if it’s just for a few minutes a day, is an important step toward treating and preventing piles.
You can use topical creams and ointments to topical reduce swelling, pain, and discomfort. These creams should be applied directly to the affected areas.
You should also avoid straining when using the toilet as this can irritate piles and make them worse. Instead, find positions which are comfortable when using the toilet, such as resting your feet on a stool, and take your time to pass stools.
Finally, many people with piles find that sitz baths can be a great way to reduce the discomfort associated with piles. These are shallow soaking baths which involve sitting in warm or hot water with your hip submerged, usually for 15-20 minutes.
