1、濟南防水公司http://www.ochf.cn/談到有的把工程造價一壓再壓的情況，造成資金不充足，所以采用劣質的材料來減低成本，造成工程的整體質量下降。
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、濟南防水公司http://www.ochf.cn/介紹有的層層轉包，工程造價層層剝皮，過多的專包，無疑增加了成本，因為每個轉包商都要獲取一定的利潤，而到了最后的直接承包并進行具體施工的服務商手上便會同樣出現(xiàn)上一種情況。
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、有的施工單位采用低劣材料、減薄防水層、改變設計材料等;有的不重視基層質量。只要反腐倡廉，抓好設計、材料、施工和保養(yǎng)等環(huán)節(jié)，防水工程質量是不能夠保證的。
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.
