GRC line has been widely used in building decoration materials, because of its unique, distinctive appearance, good quality and in the market, but nothing is perfect, GRC line if improper maintenance or other reasons will lead to the phenomenon of water leakage, then what is the reason for the water leakage?

GRC线条漏水原因：

Causes of GRC line leakage:

1、GRC线条经由多次冻融轮回后损坏；

1. GRC line was damaged after repeated freeze-thaw cycles;

2、GRC线条的内部填充的是陶粒混凝土，外墙是苯板，都属于憎水性的材料。进入保温内的水分不能尽快蒸发或者排出，造成墙体进水。

2. The interior of GRC line is filled with ceramsite concrete, and the exterior wall is benzene board, which are all hydrophobic materials. The water entering the insulation can't evaporate or discharge as soon as possible, causing the wall to enter water.
                

3、GRC线条顶部无坡度，排水不畅，，没有必然的坡度，积水过多，排水不畅，从而呈现漏水；况且GRC线条和陶粒混凝土之间有裂痕，陶粒混凝土上部抹灰层损坏严重；

3. There is no slope at the top of GRC line, the drainage is not smooth, there is no necessary slope, there is too much water, the drainage is not smooth, so there is water leakage; Moreover, there are cracks between GRC line and ceramsite concrete, and the upper plastering layer of ceramsite concrete is seriously damaged;

4、未按照施工设计图集施工GRC线条概况的聚合物砂浆抹面层及防水涂料层；后经由做尝试，将外墙线条部位保温拆除，做灌水试验断定漏水的主要原因分析GRC线条漏水。 现场对GRC线条进行网格布翻包施工，腻子层施工，涂料层施工；考虑到现场实际情况，终选择第三种方案。门式脚手架的搭设：以门架、交叉支撑、连接棒、挂扣式脚手板或水平架、锁臂等组成基本结构，再设置水平加固杆、剪刀撑、扫地杆、封口杆、托座与底座，并采用连墙件与建筑物主体结构相连的一种标准化钢管脚手架。门架、交叉支撑、脚手板、连接棒、锁臂、水平架、水平加固杆、剪刀撑、扫地杆、封口杆、底座、连墙件、栏杆、扶手。

4. Polymer mortar plastering layer and waterproof coating layer not constructed according to GRC line profile in construction design atlas; After the attempt, the external wall line part of the insulation removal, do irrigation test, determine the main cause of leakage, analysis of GRC line leakage. The GRC lines were carried out on-site construction of grid cloth, putty layer and coating layer; Considering the actual situation of the site, the third scheme was selected. Erection of portal scaffold: the basic structure is composed of portal frame, cross support, connecting rod, buckle scaffold board or horizontal frame, lock arm, etc., and then the horizontal reinforcement rod, cross bracing, sweeping rod, sealing rod, bracket and base are set, and the wall connecting parts are used to connect with the main structure of the building. Portal frame, cross support, scaffold board, connecting rod, lock arm, horizontal frame, horizontal reinforcing rod, cross brace, sweeping rod, sealing rod, base, wall connecting piece, railing and handrail.

现场的处理：

On site treatment:

1、按照原设计图集施工，GRC线条顶面做聚合物砂浆抹面并刷防水涂料；

1. According to the original design atlas, the top surface of GRC line is plastered with polymer mortar and painted with waterproof coating;

2、拆除GRC线条，粘贴苯板，然后网格布施工，腻子层施工，涂料层施工； GRC线条的应用领域日益增多，为人们带来许多视觉上的效果，增添了许多艺术性与观赏性。

2. Remove GRC line, paste benzene board, then construct mesh cloth, putty layer and coating layer; The application fields of GRC lines are increasing day by day, which brings people many visual effects and adds a lot of artistry and ornamental.
