Cofferdams and Tank Installations
Small and large cofferdams are usually four sided excavations utilising sheets and frames. For smaller cofferdams, excavators are traditionally used for installation, whereas the installation of sheets and frames in large cofferdams may involve ground and water retention, ultimately requiring a pre-driven method of installation. RMD Kwikform has a range of trench sheets, sheet piles, and hydraulic walers and props to support cofferdams and any tank or utility installation.
Our hydraulic walers are modular steel beams with full moment capacity joints that connect together to offer large clearances and spans up to 28.0m – ideal for tank installations and medium to large excavations.GEOBRACE 254, 390 AND 550 >
Hydraulic props are used for supporting waling beams or capping beams in large excavations to achieve large spans and optimum spacings, or for vertical applications such as bridge bearing replacement.
The Tubeshor prop is the only fully integrated ‘hybrid’ hydraulic bracing system with mechanical lock-off on the market.
Load monitoring is essential tool on any ground works project. Once proprietary props are installed it is simple to review, in real-time, the ground movements and wall deviation with load monitoring technology.E-PIN >
Double Acting hydraulic braces are the lightest and strongest braces available on the market. Used in conjunction with trench sheets, this is an optimum solution to safely brace smaller trenches and excavations up to 6.0m2.
