How to build a retaining wall
The retaining wall is the fundamental part of every building. In this regard, it must be made with special binders to hold the thrust of the ground and not give in to delays. For its construction just need to know the basics of the masonry and, in any case, this guide will explain step by step the work to be performed. So let’s see how to build a retaining wall.
The first thing you need to do will be to establish a good foundation, particularly if the wall has to be built on a slope and not very consistent to be necessary to prevent the slightest slip downstream of the wall. Before carrying out the casting in concrete ‘ll have to planting on the bottom of the trench of the iron sections T which will constitute a true even for the wall. Arrange the rights that allow you to achieve an erection regular after completing the foundation. Fixed for the first two places standing by the side of the embankment. These, planted in the ground, must remain perfectly still. Therefore shored with crosses and struts .
Given that the wall will have to support the thrust of the embankment will be necessary for you to give to its external facade a certain inclination. The slope should be equal to 1/6 of the wall. For example, a 1 meter high wall with a thickness of 50 cm at the base, at the top will often be 34 cm. The earlier rights will therefore be inclined with this entity and they too will have to be shored up and anchored to the upright rear by some sleepers that must not interfere with the work of construction of the wall. Cutlery on these the ropes with a counterweight to create a guide in the construction.
Arrange the bricks of the various courses always starting from the front face, the bricks as external drive back them gradually following the guidance of the rope. Performed additional control using a strip of wood that hard, posed on the edges of the bricks, will help to give uniformity to the inclination of the front face of the wall. Guaranteed, precisely as a consequence to this continuous recess, the verticality of the rear face of the wall by cutting the bricks to measure and arrange the part cut towards the inside of the wall after it has been coated with mortar .
When you have completed the wall, this will constitute a real dam against the embankment and water which penetrates when it rains. This, however, constitutes a danger to the wall because of the disruptive that might occur. So you’ll have to eliminate this problem and to do that you’ll have to create a loophole that will develop throughout the depth of the wall. Leave a gap of about a brick between the two bricks positioned on edge; and then bonded together with mortar the bricks used for the realization of the buttresses and then coated the entire bottom side of the slit of mortar smoothed with a trowel .
