RETAINING WALLS FOR SEA , FLOOD AND LAND SLIDE
DEFENCES :
Aquacast construction rate at 20 min / Sq M , is extremely fast , it is considered to be the ideal solution to rapidly solve problems of , sea erosion and floods , collapsed roads , land slide erosion or burst river embankments , it is the fastest concept in case of emergencies where time is an important factor in saving lives . Beside its flexible application uses , the extra unique piling option provides structures the extra strength and rigidity to withstand erosion and resist turnover forces .
The Aquacast w blocks system , has been recently successfully tried and tested in a sea land reclamation projectes , the walls were built directly in water without excavating foundationes or mixing
concrete . The W-blocks dry clean construction can be adjusted to all ground levels both on dry land or in water-logged areas without contaminating water .
Installers : Aquacast International have appointed and approved several international construction companies to act as our authorised installers for the UK market , the Autherised installers have years of experience in the water and erosion fields , example of such installers are , Miles Water Engineering LTD , Land and Water LTD , JT Mackley & Co Ltd , Bam Nuttall and Jackson within the UK .
AQUACAST BLOCKS FOR INTERTIDAL ESTUARY DEFENCES AT ALDEBURGH GOLF CLUB
Background
Founded in 1884 , Aldeburgh Golf Club is England ’ s second oldest maritime heathland course . The River Course , consisting of nine holes , overlooks a wide , sweeping reach of the River Alde , with wonderful views across the marshes . The course was protected from tidal flooding by earth banks , which had settled over the sixty years since they were last raised . In 2013 a tidal surge breached these defences flooding 120 Ha . of fresh water grazing marsh and the golf course on each spring tide . In 2014 a new defence was constructed along a shorter retreated line .
As a consequence of settlement over the last eight years , the new defences had settled by up to 0.5m .
As a result , overtopping was becoming a common occurrence on spring tides leading to parts of the course occasionally becoming unplayable .
Solution
Aquacast blocks were chosen as the preferred solution as the engineer designing the maintenance works was keen to reduce the risk of further settlement which would eventually lead to the sinking of the defence walls . Over time defences can sink by up to a metre in this area which would then necessitate further remedial work .
Aquacast blocks provided a realistic option by providing sufficient strength whilst minimising the weight impact . The alternative was to create earth banks but this has significant weight implications . A one metre run of an earth bank means 16 m3 of earth , weighing approximately 30,000 kgs , would be required . This compares to Aquacast where the weight would be between 300-400 kgs depending on the height of the wall .
