PAVING BLOCKS

PAVEMENT, IN CONSTRUCTION, IS AN OUTDOOR FLOOR OR SUPERFICIAL SURFACE COVERING. PAVING MATERIALS INCLUDE ASPHALT, CONCRETE, STONES SUCH AS FLAGSTONE, COBBLESTONE, AND SETTS, ARTIFICIAL STONE, BRICKS, TILES, AND SOMETIMES WOOD.

IN LANDSCAPE ARCHITECTURE, PAVEMENTS ARE PART OF THE HARDSCAPE AND ARE USED ON SIDEWALKS, ROAD SURFACES, PATIOS, COURTYARDS, ETC.

WE AT SBF INTERIORS AND OUTDOOR SOLUTIONS LIMITED MAKE A VARIETY OF PAVING BLOCKS THAT COME IN A NUMBER OF COLOURS AND SIZES

MAJOR FAILURES: THE MAJOR FAILURES CAUSED BY POOR CONSTRUCTION IS PONDING, DEFORMATION, AND POTHOLES.

THE MAIN CAUSES OF FAILURE- INCLUDE LEAVING BLACK COTTON SOIL UNEXCAVATED TO THE ALLOWED DEPTH. THIS RESULTS IN HEAVING THAT MAKES THE SURFACE UNEVEN, LEADING TO PONDING AND POTHOLES.

THEN THERE IS POOR COMPACTION OF THE GROUND AND BACKFILLING.WHERE THE STONE LAYER IS NOT WELL PITCHED THE SURFACE DEVELOPS DEPRESSION WHEN USED BY VEHICLES.

FOR STONE LAYER, INADEQUATE FILLING OF VOIDS MAY CAUSE LOOSENING AND BREAKING OF BLOCKS. TO AVOID THIS, THE BLINDING MATERIAL, WHICH IS NORMALLY QUARRY DUST OR SAND, MUST BE VIBRATED USING A LIGHT PLATE COMPACTOR UNTIL NO MORE IS LOST INTO STONE LAYER.IF THIS IS NOT DONE WELL, THE BLINDING MATERIAL WILL LATER BE LOST INTO STONE LAYER AS VEHICLES VIBRATE THE GROUND.

POOR DRAINAGE OF THE DRIVEWAY OR PARKING WILL CAUSE PONDING AND ALLOW WATER INTO THE GROUND SUPPORTING THE BLOCKS. ONCE THE GROUND IS SOAKED, POTHOLES WILL DEVELOP AS THE MUDDY MATERIAL IS PUSHED OUT.TO RESOLVE THESE PROBLEMS, ENGAGE AN ENGINEER WHO WILL STUDY THE TYPE OF SOIL, AND GROUND TOPOGRAPHY AND COME UP WITH AN APPROPRIATE DESIGN.

DURING IMPLEMENTATION, THE ENGINEER WILL NEED TO VISIT THE SITE REGULARLY TO APPROVE EACH STAGE OF CONSTRUCTION.
