installs micropling. Micropiling can be defined as small diameter piles, typically less than 150mm, where the pile load is carried structurally predominantly by the pile reinforcement. Therefore micro-piles are often relatively heavily reinforced with a substantial full length central reinforcement bar. Micropiles are normally grouted due to small volumes.
offers the installation of self drilled micropiles where a central hollow threaded reinforcement bar acts as both final reinforcement in the completed pile and as the drill rod during installation. Some of our micropiles are installed with sacrificial drillbits under a grout flush. In granular deposits in particular the impregnation of grout into the surrounding ground significantly enhances the geotechnical capacity of the pile. Call for more information.
The purpose of a foundation is to support a building and prevent it from sliding or slipping. Most foundations are made of concrete, but they can also be built from stone, wood and brick. Some of the more common types of foundations include a concrete slab foundation, a crawlspace foundation and a basement foundation.
Concrete slab foundations are built by pouring concrete into a wood frame that is flush with the ground. The concrete usually rests on a bed of gravel, and is thicker where the outside and interior walls are located. Thick wire is put into the concrete to help prevent it from cracking. Slab foundations are common in mild and warm climates where the ground doesn't freeze.
A crawlspace foundation is typically found in places where the soil has a heavy clay content. It is constructed with a hollow block or poured concrete frame that supports the home's perimeter walls. It leaves room for a person to crawl between the floor of a house and the ground. One of the advantages of a crawlspace foundation is that there is space for the installation of plumbing, electrical components and air ducts.
Basement foundations have significant room between the home's floor and ground. They are normally built with a concrete slab floor, and poured concrete or concrete block walls.
Evidence of a foundation that is in need of repair includes floor cracks, wall cracks, foundation cracks, bowed walls, uneven or slopping floors, leaning chimneys, wall separation, wall rotation, nail popping, and doors and windows that don't open or close properly. Moisture can enter homes through wall cracks, as well as doors and windows that don't fit correctly, causing further damage to the house. Air can also penetrate through cracks and openings, increasing utility bills. Severe foundation damage can eventually result in a partial or total building collapse.
Rainwater, sprinkler water, and water from broken plumbing can cause significant damage to a home's foundation. Even though initial signs of water damage may seem insignificant, any evidence of water problems should be thoroughly investigated to prevent the foundation from weakening.
Plumbing should be regularly checked for leaks, along with washing machine hoses and water heaters. One way to find out if there are any plumbing issues, is to take a water meter reading and then turn off all faucets and any appliances that use water. Don't flush toilets for an hour. Then, re-check the meter to see if the amount of water used has increased. If so, that indicates that you have a plumbing leak that could then cause damage to the foundation. You can also purchase water alarms with built-in moisture sensors, and install them near water-using appliances, and under sinks and toilets.
If you suspect your foundation has structural issues, a qualified foundation repair company should be contacted at once to conduct a thorough inspection of your home foundation. You will get valuable advice regarding the source of any problems, and what should be done to correct the situation. If foundation repairs are needed, they should be made as soon as possible to avoid more costly trouble that will develop later on.
