Bridge Abutment Drainage Block

Advantages of the Bridge Abutment Drainage Block

• High load bearing strength of 7N/mm2 and greater.
• Excellent flow rate through porous concrete block into preformed drainage channel.
• Vertical channel system creates drainage for water against structure.
• Superior lateral strength and resistance to crushing from backfill earth pressures.
• Simple easy to lay mortar free system.
• Fewer breakages - design strength ensures damages are kept to a minimum even with heavy handed treatment.
• More cost effective.
• Reduced surface contact area minimises capillary action between block and concrete structure ensuring less moisture travel through structure.
• High performance drainage solution for concrete structures by providing a positive and rapid evacuation of subsurface ground water before accumulated hydrostatic pressure can compromise the structure.
• Reduces the effect of pore water pressure.
