1、济南防水公司http://www.tianyujian.com/谈到有的把工程造价一压再压的情况，造成资金不充足，所以采用劣质的材料来减低成本，造成工程的整体质量下降。
Jinan waterproofing company talked about some of the construction cost of a pressure situation and then pressure, causing the funds are not sufficient, so the use of inferior materials to reduce costs, resulting in a decline in the overall quality of the project.
2、济南防水公司http://www.tianyujian.com/介绍有的层层转包，工程造价层层剥皮，过多的专包，无疑增加了成本，因为每个转包商都要获取一定的利润，而到了最后的直接承包并进行具体施工的服务商手上便会同样出现上一种情况。
Jinan waterproofing company introduced some layers of subcontractors, project cost layers of peeling, excessive designed package, will increase the cost, because each subcontractor must obtain a certain profit, but to the last direct contracting and concrete construction the service provider will also appear on the hands of a situation.
3、有的施工单位采用低劣材料、减薄防水层、改变设计材料等;有的不重视基层质量。只要反腐倡廉，抓好设计、材料、施工和保养等环节，防水工程质量是不能够保证的。
Some construction units using inferior materials, thinning waterproof layer, changing the design materials; some do not pay attention to grassroots quality. As long as anti-corruption, good job design, materials, construction and maintenance and other sectors, waterproof construction quality is not guaranteed.
