Strong or whether the foundation is very influential to the durability of a building. If the foundation is weak, it is likely that the building will impunity decline later. And vice versa if the durability of its strong foundation, building on it will be spared from the decline due to weak soil bearing capacity. Much can be done when creating the foundation, such as using stone or crushed stone with mortar specie ratio of one part cement to four parts sand. There is also a system that uses reinforced concrete, which species or cement mortar has a ratio of one part cement mixed with two parts sand and three parts gravel and in it were given iron reinforcement.
To create a strong foundation from which will carry the load and to increase the load pressure evenly, for that on the foundation it must be installed sloop with a ratio of one part cement mixed species two parts sand, and three gravel and iron reinforcement given therein. Creating a foundation like this, it can also be used plastic sheets or polyhedral are usually made for tents sidewalk food stalls. The plastic sheet over the deployment had been dug for the future construction of foundation. Head of the breakwater that had been planted prior to sunset pounded foundation excavation of the soil surface to a depth of approximately 20 cm. Aims to be a plastic sheet that will be held not tear or penetrate the breakwater head earlier.
