Application of Screw Piles

INSTANT FOUNDATIONS 

SCREW PILES CAN BE USED FOR MAJOR CONSTRUCTION PROJECTS INCLUDING COMMERCIAL PROJECTS AND BRIDGES. PILES CAN BE INSTALLED IN ROUGH TERRAIN WITHOUT THE NEED FOR SPECIAL ACCESS OR EARTHWORKS.

SCREW PILES CAN BE INSTALLED UP TO LOAD CAPACITIES OF 150 TONNES AND WITH LENGTHS OF UP TO 30 METRES. THIS MAKES THE INSTANT FOUNDATIONS SCREW PILE EXTREMELY VERSATILE IN A WHOLE RANGE OF CONSTRUCTION PROJECTS. SCREW PILES ARE APPLICABLE FOR USE IN BOTHE COHESION LESS SOILS AND COHESIVE SOILS. ONE ADVANTAGE OF INSTANT FOUNDATIONS SCREW PILES ARE THAT THE EXCAVATOR BASED PILE INSTALLATION RIGS OFFER LOWER RATES OF PROCUREMENT COMPARED TO SPECIALISED TRADIIONAL PILING RIGS.

TRADITIONAL PILING RIGS CAN BE VERY EXPENSIVE TO PURCHASE AND OPERATE BECAUSE OF THE UNIQUE NATURE OF THEIR APPLICATIONS. SCREW PILES HOWEVER CAN BE INSTALLED FROM EXCAVATOR BASED EQUIPMENT WHICH IN ADDITION TO INSTALLING SCREW PILES, CAN BE USED FOR ALL THE PURPOSE BUILT APPLICATIONS THAT AN EXCAVATOR WOULD BE USED FOR. THIS RESULTS IN MUCH LOWER SITE ESTABLISHMENT AND OPERATIONG COSTS FOR THE EQUIPMENT AND THEREFORE HAS A BENEFIT OF LOWERING THE TOTAL INTALLATION PRICE. THE RATES OF PRODUCTION AND INSTALLATION OF SCREW PILES ALSO EXCEED THE INSTALLATION RATE OF OTHER PILING METHODS. SCREW PILES ARE FABRICATED IN A QUALITY CONTROLLED FACTORY ENVIRONMENT. THIS RESULTS IN THE RAW PRODUCT (FABRICATED SCREW PILES) BEING OF VERY HIGH QUALITY. THE ADDED ADVANTAGE OF VIBRATION FREE PILING IS APPLICABLE ON COMMERCIAL BUILDING SITES WHERE THE SITE MAY BE SURROUNDED BY SENSITIVE AND INFLEXIBLE STRUCTURES. IN THIS CASE, A PILING SYSTEM WHICH MAY CAUSE VIBRATION, MAY INCREASE THE RISK OF DAMAGE TO ADJACENT BUILDINGS AND COULD POSSIBLY INITIATE LITIGATION BETWEEN THE BUILDING OWNERS AND THE PILING CONTRACTOR.

INSTANT FOUNDATIONS  SCREW PILES CAN BE INSTALLED AS EARTH REINFORCEMENT. ONCE INSTALLED ANCHORS ARE COMPLETED, ANCHORS CAN BE DIRECTLY - LOAD TESTED - USING HYDRAULIC JACKS. ANCHORS CAN PENETRATE MOST STRATA, INCLUDING LOW STRENTH ROCK. THE SPEED OF INSTALLATION OF THE ANCHORS EXCEED THAT OF TRADITIONAL GROUND ANCHORS. ANCHORS CAN BE INSTALLED THROUGH TEMPORARY SHEET PILING OR FIXED TO CONCRETE PLATES WHICH BEAR AGAINST THE EMANKMENT FACE. ANCHORS CAN BE PRETENSIONED. ANCHORS CAN BE REMOVED OR DE-TENSIONED AT A LATER TIME. 

INSTANT FOUNDATIONS SCREW PILES ARE USED WIDELY TO SUPPORT RESIDENTIAL CONSTRUCTION PROJECTS BY USING GREAT ECONOMIES OF SCALE AND SPEED OF INSTALLATION. SREW PILES ARE WIDELY RECOGNISED AS THE FASTEST INSTALLATION OF ALL PILING METHODS. PILES CAN LITERALLY BE INSTALLED AND HAVE CONCRETE FOOTINGS POURED OVE THE PILES IN THE SAME DAY. FOR LUXURY RESIDENTIAL PROJECTS ANY SMALL AMOUNT OF DEFLECTION IN THE FOOTING SYSTEM CAN BE EVIDENT IN THE PERFORMANCE OF THE STRUCTURE. WHILE THIS IS UNDESIRABLE IN THE LUXURY HOUSING MARKET, INSTANT FOUNDATIONS SCREW PILES CAN BE USED TO GREATLY REDUCE OR ELIMINATE ANY POTENTIAL SETTLEMENT WHICH MAY RESULT IN STRESS UPON THE STRUCTURE. WATER FRONT DEVELOPMENTS ARE BECOMING INCREASINGLY POPULAR IN THE RESIDENTIAL HOUSING MARKET. SCREW PILES CAN BE USED EFFECTIVELY TO SUPPORT THE LOAD OF THE STRUCTURE AT SUFFICIENTLY DEEPER LEVELS TO ELIMINATE ANY SETTLEMENT ADJACENT TO THE WATERWAY.

REMOTE LOCATIONS ONLY FURTHER DEMONSTRATE THE BENEFITS OF INSTANT FOUNDATIONS SCREW PILES IN NEW OR REMEDIAL WORK ON PIPELINES. THE INSTALLATION ON PILES, FABRICATION OF SUPPORTS AND CORROSION PROTECTION CAN BE COMPLETED IN A SINGLE PASS AT A FRACTION OF THE COST OF CONCRETE CONSTRUCTION.

AS PREVIOUSLY NOTED THE SPEED OF INSTALLATION OF INSTANT FOUNDATIONS SCREW PILES ENABLES THE PIPELINE SUPPORTS TO BE INSTALLED RAPIDLY. TYPICALLY, THE PILING RIG IS FOLLOWED UP WITH MOBILE WELDING EQUIPMENT. THE HEAD OF THE PILE IS CONNECTED TO THE PIPELINE EITHER DIRECTLY BY WELDING OR VIA A PIPE SUPPORT CRADLE. THE PILE SUPPORTS CAN BE VISUALLY INSPECTED TO MONITOR THE EFFECT OF ANY ATMOSPHERIC CORROSION AND PROTECTION METHODS CAN BE AFFECTIVELY EMPLOYED.

ENGINEERS OF TOWERS AND LARGE SIGNAGE STRUCTURES REQUIRE FOUNDATION SYSTEMS DESIGNED TO CARRY THE LARGE OVERTURNING MOMENTS, TENSION AND COMPRESSION LOADS THAT CAN BE DEVELOPED. GENERALLY, TOWERS HAVE A RELATIVELY SMALL NUMBER OF SCREW PILES AT EACH SPECIFIC LOCATION. A SCREW PILING RIG CAN BE USED IN ITS TRADITONAL APPLICATION TO EXCAVATE THE PILE CAP AND FOOTINGS PRIOR TO INSTALLING THE SCREW PILES, THUS ELIMINATING THE NEED TO ESTABLISH A PILING RIG AND AN EXCAVATOR TO COMPLETE THE CONSTRUCTION OF THE TOWER FOUNDATION. INSTANT FOUNDATIONS SCREW PILES HAVE BEEN USED IN MANY SITUATIONS TO PROVIDE EXCELLENT BEARING CAPACITY FOR BOTH UNDER COMPRESSIVE AND TENSILE LOADS. THE RESITANCE OF THE HELICAL PLATE TO UPLIFT TENSION LOADS RESULTS IN VERY HIGH TENSION PULL OUT LOADS BEING ACHIEVED FROM INFIELD TESTING BY INSTANT FOUNDATIONS.

INSTANT FOUNDATIONS SCREW PILES CAN BE USED EFFECTIVELY IN UNDERPINNING OF FAILED BUILDINGS. A SCREW PILING RIG CAN WORK FROM THE INSIDE OF THE BUILDING WITH LIMITED HEAD HEIGHT AND USE SEGMENTED PILES AS REQUIRED. THERE IS A RANGE OF SIZES OF EXCAVATOR BASED SCREW PILING RIGS WHICH CAN BE USED IN UNDERPINNING APPLICATIONS. FOR DOMESTIC OR COMMERCIAL CONSTRUCTION UNDERPINNING PILING RIGS OF WIEGHTS BETWEEN 3-5 TONNES CAN BE USED WITH EASE TO ACHIEVE THE REQUIRED PILE LOAD CAPACITIES. FOR LARGER COMMERCIAL PROJECTS WERE THE LOADS ARE IN EXCESS OF 30 TONNES, EXCAVATOR PILING RIGS CAN BE HAND PICKED TO INTALL SCREW PILES TO SUIT THE UNDERPINNING REQUIREMENTS. THE EXCAVATOR CAN ALSO BE USED TO EXCAVATE THE PILE CAPS AND FOOTING BEAMS IN THIS APPLICATION.

INSTANT FOUNDATIONS SCREW PILES ARE THE PURE ENVIRONMENTAL CHOICE FOR DEEP FOUNDATIONS. SCREW PILE RIGS CAN REACH OUT UP TO 20m, THEREBY NOT DAMAGING VEGETATION ADJACENT TO WATERWAYS. THERE IS NO ENVIRONMENTAL POLLUTION FROM NOISE VIBRATION, NO SOIL SPIL AND NO CONCRETE WASTAGE.

INSTANT FOUNDATIONS SCREW PILES ARE GENERALLY PURPOSE BUILT FOR THE APPLICATION, WASTAGE IS VIRTUALLY ELIMINATED. SCREW PILES CAN BE USED EFFECTIVELY IN FOOTBRIDGES, ROAD BRIDGES AND A RANGE OF OTHER ENVIRONMENTAL PROJECTS WHERE THE INSTALLATION RATES ARE VERY FAST AND EXCEED THOSE RATES OF TRADITIONAL POLING METHODS, EFFECTIVELY REDUCING CONSTRUCTION PROCESS TIME .

INSTANT FOUNDATIONS SCREW PILES ARE IDEAL FOR JETTYS AND OTHER MARINE APPLICATIONS WHERE STRUCTURES SUCH AS RESTAURANTS ARE BUILT OVER THE WATER, PROVIDING AN ENVIRONMENTALLY SAFE MEANS FOR RETAINING THE SURROUNDING VEGETATION WHEN CONSTRUCTING BOARDWALKS.
