The riprap rock revetment is applied to control streambank erosion and/or protect shoreline using rock or other material placed on sloping bank. It is designed and executed in such a way to protect the harbor basins from the effects of harsh waves and sea currents, for the stability of the vessels, anchored in the ports or harbors. We ensure the built is of the highest quality.
A breakwater structure is designed to absorb the energy of the waves that hit it, by using rock or concrete armor units, breakwater is built to protect port, reduce erosion of shoreline and islands against extreme wave conditions. The structure built in three layers usually. Depending on the design, based on load conditions, the size and specifications of each layer may vary. Normally, the base would be quarry run rocks of smaller size, followed by an under layer of rocks sized less than a ton. Then comes the armor layer of larger rocks. The crest of the breakwater would be on this layer. The crest is the table-like topmost portion of the breakwater.
A seawall (or sea wall) is a form of coastal defense constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The purpose of a sea wall is to protect areas of human habitation, conservation and leisure activities from the action of tides, waves, or tsunamis.

A quay wall is an earth retaining structure which is used to dock floating vessels and transfer goods. Quay walls are of
various types and are used for mooring and berthing floating vessels such are barges, container vessels, ships, boats etc.
Various types of quay walls are as follows:
Sheet piled quay walls
Steel cellular / caisson quay walls
Reinforced concrete diaphragm walled quay walls
Gravity block quay walls
Reinforced concrete counterfort quay walls
ALFATTAN CONTRACTING specializes in steel sheet pile and gravity wall.
A slipway, also known as boat ramp or launch or boat deployed, is a ramp on the shore by which ships or boats can be moved to and from the water. They are used for building and repairing ships and boats, and for launching and retrieving small boats on trailers towed by automobiles and flying boats on their undercarriage. ALFATTAN CONTRACTING experienced in constructing and repairing slipway.
Tubular Piling Installation Works
Steel tubular piles are often used for foundations for bridges, scaffolding and buildings, as well as making an essential part of fenders or combi-walls. Steel Tubular Piles are mainly used in marine projects and in environments with a limited working area or limited height. The suitable tube diameter and wall thickness can be determined depending on the application and the required load-bearing capacity. For extra bearing capacity the tube can be produced with a bottom plate. Depending on the CPT information the installation of the tubular piles can be done by using a hydro or diesel hammer. Tubular piles with a bottom plate can also be piled using a drop hammer inside the tube. The internal driven steel tubular pile is a vibratory free, soil displacement piling system.
A floating dock, floating pier or floating jetty is a platform or ramp supported by pontoons. It is usually joined to the shore with a gangway. The pier is usually held in place by vertical poles referred to as pilings, which are embedded in the seafloor or by anchored cables. Frequently used in marinas, this type of pier maintains a fixed vertical relationship to watercraft secured to it, independent of tidal, river or lake elevation.
