CONCRETE PRESSED PILINGS: The Pressed Piling, the most used and most cost-effective pier on the market, consists of pre-made concrete cylinders which are pressed into the ground by hydraulic rams. The weight of the house is used to push against, and the piers are installed with about 3+ times the force they will experience when holding up the
Using my hand, I press my fingers into the concrete. If I can only press into the concrete about 1/8 to 1/4 inch, this tells me the concrete is close to or ready to start power troweling. If I can only press my fingers into the surface 1/8 inch, I try walking on the surface.
Many pressed pier contractors are using cheap hydraulic bottle jacks to press these cylinders. This low tech approach is one of the reasons that many foundation engineers will not recommend their use. These are the reasons that pressed concrete pier contractors advertise the lowest prices. If a low price is more important than a real repair
Concrete and other cementitious products traditionally have very high compressive strength and much lower tensile strength. The rule of thumb is that portland cement concrete has a tensile strength that’s about 10% of the compressive strength, but that percentage varies based on the mix design.

Jun 16, 2015· Using drilled concrete piers or pressed concrete pilings are older methods that have largely been supplanted by the use of steel – a stronger material that allows for easier, faster placement and an integrated approach to raising the structure. When it comes to steel piers, there are two kinds – hydraulic push piers and helical piers.

In pile foundation, the loads are transferred by means of vertical timber, concrete or steel. Pier foundation consists of cylindrical columns to support and transfer large superimposed loads to firm strata. 2: Piles are driven through the overburden soils into the load-bearing strata. Piers are drilled with the drill machine. 3

Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during production, in a manner that strengthens it against tensile forces which will exist when in service.: 3–5 This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service.

Concrete piers are cost effective reliable, and easy to install, which make them the most commonly used pier for foundation repair. Their technical name is “pressed concrete piers”. Pressed concrete piers are installed by digging a 2’x2’ hole under the edge of your foundation; a hydraulic press then pushes the 6”x12” cylinder into

Jan 01, 2011· Final Verdict: Steel Piers vs. Pressed Concrete Piling Repair Both the Steel Piers and the Pressed Concrete Piling Method are commonly used for foundation repair. However, if one was to evaluate which method is better than the other, it is clear that the steel pier method is the preferred method for long-term, high-quality foundation repairs.
Nov 01, 1980· Therefore, it can be concluded that pressure has caused a permanent increase in the strength of pressed concrete. Comparison of graphs A and B in either Fig. 1 or Fig. 2 indicate that at early ages pressed samples exhibit a higher strength relative to their own 28-day strength, S~,28, than that shown by control samples relative to f~ .

Feb 01, 2013· Foundation Repairs: Hydraulic Push Piers vs. Pressed Concrete Pilings. Feb 1, 2013 • By Matthew Stock with Barry Schilling. When your home suffers structural foundation damage, it’s pretty serious business. It’s not a repair you can put off because the damage to your foundation – and the rest of your home – can only get worse.
The hammers are a great complement to the PTC vibratory hammers, as they can be operated with the same powerpack or piling rig. Hammers can be fitted with numerous helmets for pipe, concrete piles, and even sheet piles. The hydraulic piling hammer is capable of up to 61,000 ft/lbs of impact energy, and up to 44 blows per minute.
After concrete is placed, the concrete increases in strength very quickly for a period of 3-7 days. Concrete which is moist cured for 7 days is about 50% stronger than uncured concrete. Water curing can be done after the slab pour by building dams with soil around the house and flooding the slab. The enclosed area is continually flooded with water.
Vibro Pile. A vibro-pile is a closed off casing that is vibrated into the ground displacing and "densifying" all the material in its path. The casing is then filled with concrete and reinforcement and then extracted (or filled with concrete as it is extracted and the reinforcement is installed later.)
The hydraulic pressing process consists basically of filling a mould with a wet mix concrete with an aggregate/cement ratio of between 5:1 & 7:1. Then applying pressure in the order of 100psi (6.9MN/m2), excess water is then expelled and compaction is complete. The aggregates and cement are accurately batch-weighed and dispensed into a mixer.
