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線條漏水原因：

Causes of GRC line leakage:

1、GRC線條經由多次凍融輪回后損壞；

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

2、GRC線條的內部填充的是陶粒混凝土，外墻是苯板，都屬于憎水性的材料。進入保溫內的水分不能盡快蒸發或者排出，造成墻體進水。

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線條頂部無坡度，排水不暢，，沒有必然的坡度，積水過多，排水不暢，從而呈現漏水；況且GRC線條和陶粒混凝土之間有裂痕，陶粒混凝土上部抹灰層損壞嚴重；

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、未按照施工設計圖集施工GRC線條概況的聚合物砂漿抹面層及防水涂料層；后經由做嘗試，將外墻線條部位保溫拆除，做灌水試驗斷定漏水的主要原因分析GRC線條漏水。 現場對GRC線條進行網格布翻包施工，膩子層施工，涂料層施工；考慮到現場實際情況，終選擇第三種方案。門式腳手架的搭設：以門架、交叉支撐、連接棒、掛扣式腳手板或水平架、鎖臂等組成基本結構，再設置水平加固桿、剪刀撐、掃地桿、封口桿、托座與底座，并采用連墻件與建筑物主體結構相連的一種標準化鋼管腳手架。門架、交叉支撐、腳手板、連接棒、鎖臂、水平架、水平加固桿、剪刀撐、掃地桿、封口桿、底座、連墻件、欄桿、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.

現場的處理：

On site treatment:

1、按照原設計圖集施工，GRC線條頂面做聚合物砂漿抹面并刷防水涂料；

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線條，粘貼苯板，然后網格布施工，膩子層施工，涂料層施工； GRC線條的應用領域日益增多，為人們帶來許多視覺上的效果，增添了許多藝術性與觀賞性。

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.
