Paving block or also called Concrete Paving be a favorite alternative for hardening roads and home yards. Paving blocks are available in various sizes, colors, and patterns so that they can be adjusted to your needs. Paving blocks are also somewhat environmentally friendly because water can still seep through the gaps of the paving block arrangement.
If you are interested in using paving blocks, you should do the job of installing paving blocks properly. Because if not, then the surface of the paving block becomes easily bumpy. Then how do you install the paving block to make it strong and good? There are several steps that must be done carefully. Here’s how to install the complete paving block.
Prepare a solid land structure or foundation
Do not rush to install a paving block if the land has not been prepared properly. For that, clear the land from trash and grass. Then do the leveling of the land surface, close the hole and level the dirt mounds.
If the land requires filling, lay the fill material on solid soil and then solidify it using a roller or horse stamper. Avoid leveling or closing the holes by using bottom sand. This compaction process should also be accompanied by water in order to obtain a perfect fill density. If the paving block is to be installed on a road that is passed by a vehicle, then make sure the foundation has a slope of 2.5%. As for the sidewalk, make sure the slope is 2%.
Installation of concrete and supporting concrete
Limiting concrete is one part of a concrete block that is locked which functions to clamp and hold the paving block so that it does not shift when holding the load. The boundary concrete is in the form of precast concrete and some are in the form of cast concrete in place. If using concrete from precast concrete, it must be installed on supporting the concrete. The goal is to create a strong bond between the concrete barrier and the foundation so that it does not easily shift.
The limiting concrete is often combined with water ropes and water mouths as channels for removing rainwater. If the confluence between the boundary concrete and the block layer is not given a water rope, then the limiting concrete is usually very easy to be hit by the friction of the vehicle wheels.
Laying sand base
Sand for the base is sand with a certain thickness that is used as a base for laying paving blocks. Also, make sure the sand for the base is clean of mud and other impurities. When used, the base sand must be dry or at least less than 10% water content
If the paving block installation is not completed in one day, then leave about 1meter of the sand base from the last row of paving blocks. Later, the base sand that had not been installed with paving blocks had to be smoothed and leveled again.
Installation of paving blocks from one direction
Carefully install the first-row paving block. A good pattern can be produced if the installation is done by following the supporting thread and with the right angle to the concrete barrier. Meanwhile, the edge holes can be filled with compaction. Installation of paving blocks is done by going forward and installation workers are above the installed paving blocks.
For good results, the installation of paving blocks should be done in one direction. If it has to be done from two directions, then the angle of the meeting pattern or the change in angle should be limited by a transverse brick stacking pattern.
If all paving blocks are installed, then fill in between the grout paving blocks using stone ash. After that, tighten the paving block with a baby roller or frog stamper one round to two rounds. The goal is to appear interlocking style between paving blocks. Then clean the surface of the paving block from the remnants of stone ash.
Well, that is the step by step on how to install strong and good paving blocks. Armed with this guide, land covered by paving blocks will have a flat, sturdy surface and not easily bumpy.
