Revetment Systems

Ankalok

Ankalok fully interlocking precast concrete revetment embodies a unique double anchor head shape which ensures that each block in revetment is positively interlocked with the six surrounding units.

The unique design of Ankalok provides units of exceptionally high handling and in service strength with the soil/gravel retaining cells being formed by the configuration created when the blocks are laid and interlocked together.

The size and spacing of the cells have been designed to afford maximum protection from erosion whilst permitting the release of excess pore water pressure. Above normal water level the block cells may be soil filled and seeded thus further aiding stability by root establishment.

Below water level the cells can be filled with a graded gravel to add extra weight to the armour layer and additional resistance to vertical displacement.

The simple one unit system enhances a straight forward laying procedure which allows rapid installation without the need for highly skilled labour.

Ankalok is particularly appropriate for sites with a difficult access where larger systems such as pre-assembled panels needing heavy handling equipment cannot be used.

Dycel

Dycel is a fully interlocking precast concrete revetment system designed to provide exceptional protection against embankment erosion above and below water level whilst ensuring the flexibility essential to cope with variations in embankment profile.

Dycel’s full depth cellular structure enables the system’s stability to be enhanced by filling and seeding voids in situations above water level of by filling the voids with graded aggregate where the product is used below water level. Seeding with prevailing natural vegetation also enables structures to harmonise perfectly with the local environment. A solid system is available for use in particularly abrasive environments or to provide additional toe weight.

When tested as part of the CIRIA field trials in connection with The Design of Reinforced Grass Waterways (Ref. CIRIA Report 116), the Dycel 100 system withstood flow velocities in excess of 8m/sec when laid in a steep trapezoidal channel with geotextile under-layer.

The Dycel system can be laid quickly and easily without the need for skilled labour.

Dytap

Traditionally natural stone and concrete have been used to construct decorative hardwearing surfaces.

Dytap is a system of precisely interlocking precast concrete units which when laid on embankments, vertical cladding or walling, or even underwater, will provide a protected surface with a visual appearance of natural random stone with the installation benefits of precast concrete.

Since its inception the Dytap system has undergone continual development to provide a primary armour/cladding system of extremely high stability with a hardwearing, aesthetically pleasing surface finish.

The combination of natural stone and concrete provides a precast unit of unique form and appearance which enables the Specifier to choose a finish which harmonises with the environment.

The variety of finishes includes most naturally occurring stones and plain textured and coloured concrete.
