PILING:
RGF’s piling expertise includes the design and installation of most types of piles ranging from the mini piles to large diameter driven and bored piles.

•Mini piles:
RGF executed underpinning projects virtually all over the Kingdom, thus gaining an unparalleled experience in this area. Our fleet of rigs include: small self-propelled units, capable of operating in tight places, and powerful enough to drill piles up to 30cm in diameter and in excess of 25m in depth.

•Driven Cast In-Situ Piles:
For driving Vibrex piles, RGF introduced state-of-the-art vibrohammers to the Saudi Arabian construction industry in 1994. Since then, we have successfully completed several projects using our IHC S70 and S90 hydrohammers and our Fundex rigs.

•H-Piles, Tubular Piles, and Sheet Piles:
H-Piles and Tubular Piles can be installed with our state-of-the-art hydrohammers. Our vibrohammers, such as the ICE-815 and the ABI versatile machines have been used extensively to install thousands of meters of sheet piles on projects in the Eastern and Western Provinces of Saudi Arabia.

•BORED LARGE DIAMETER PILES:
RGF has established itself as a strong and efficient bored piling contractor with acquisition of powerful and versatile rigs supported by an impressive pool of drilling tools and accessories, capable of addressing any type of soil conditions.

STONE COLUMNS
RGF’s diversity in foundation services is the design and installation of Stone Columns. Using vibrohammers, RGF has successfully installed Stone Columns for a number of projects. The technique employed is referred to as the “Dry Method” technique, which relies on soil displacement. With the acquisition of the Pennine Vibrofloats, RGF has installed Stone Columns using the “Wet Method” replacement technique for several sites on the Eastern and Western coasts of Saudi Arabia.

SHOTCRETING & ANCHORING
This expertise goes hand in hand with bored, driven, and sheet piles that are used to retain the sides of open excavations. RGF owns modern equipment geared to driving horizontal or angled anchors and nails, along with the necessary tensioning jacks and the know-how for operation and testing in compliance with international standards.

GROUTING & DEWATERING
RGF possesses in-house capabilities to design grout mixes suitable to a variety of ground conditions and to perform multipurpose high pressure grouting operations.

Our staff is also qualified and well experienced in the design and implementation of dewatering schemes for open excavations using techniques ranging from open sumps to well point and deep well systems.
