BENEFITS OF THE TBLOCK SYSTEM

Simplicity

  • The TBLOCK is made of concrete only.
  • No steel or other reinforcement is required in the manufacture of the TBLOCKs.
  • TBLOCKs are manufactured in a simple two-part mould that is re-usable each day.
  • TBLOCKs are available for assembly one month after being poured.

Design

  • The Design Engineer can select the size and weight of the TBLOCK to suit the tidal, wave height and on site lifting conditions.

Cost effectiveness

  • Less volume of material required: The cross sectional area of a TBLOCK structure is less than that of structures using other methods.
  • The material cost of an all TBLOCK structure can be less than half of an all rock armour structure.
  • TBLOCKs can be made on site from ready mixed concrete.
  • Reduction in material used also reduces the transportation costs involved on any project.

Interlocking

  • Unlike most other systems the TBLOCK does not rely on random interlock. It gives a guaranteed interlock in two planes so that no one unit can be displaced.

It can be used in all ground conditions.

  • TBLOCKs can be built on rock, shale or clay.
  • Each vertical column can settle independently: The assembled TBLOCKs create a series of interlocked vertical columns with a central vertical void that can be used for piling or to strengthen the assembled column.

Environment

  • TBLOCKs do not attract rodents and debris unlike structures built with rock armour and other random interlock features.
  • The stepped ‘saw tooth’ internal wall absorbs ‘wave-wash’ energy.

Aesthetics

  • TBLOCKs can be profiled to offer an attractive sculptured appearance when assembled.

  • The TBLOCK structure can follow contours; it does not have to be laid in straight lines.

TBlock Assembly Configurations
Variations in TBlock assembly can produce a variety of straight line arrangements.
Using a combination of the three configurations shown enables coast contours
to be followed.

  • TBLOCKs can also be coloured.

Amenities

  • TBLOCKs offer a vertical ‘saw tooth’ wall that offers opportunities for amenity development for fishermen, sailors and tourism potential.

Handling

  • TBLOCKs can be lifted in a variety of ways to suit the site conditions and available facilities.

Hydraulic properties

  • TBLOCK structures can be designed so that a stepped structure in two planes dissipates wave energy.
