測試方法和程序

Testing Method and Requirements:

Test to Window Grouting

Time :	Conduct test as early as practicable before the commencement of external wall rendering. (Curtain wall system, internal windows and aluminium louvres shall be exempted from the testing)
Method :	a) To conduct test after window surround grouting has been completely dried and hardened but before waterproof coating application, normally 3 days after grouting.
	b) To pour a continuous and unpressurized flow of water by garden hose evenly along the entire length of the grouted joints at a rate of 2 m per minute.
	c) To start the test from the lowest horizontal joint at the sills, then upward along window jambs, and lastly the topmost horizontal joint at window head.
	d) Detail testing method and requirements shall be referred to the speciﬁcation.
Inspection :	e) To observe the inner surface of the grout for any water stain or leakage, the test is passed if no water leakage occurs.
	f) If water leakage occurs, identify the location for making good, and then repeat from step “b” to “e”.
	g) If there is still water leakage after the second test, all grouting has to be hacked off and re-applied for a repeat of the test.
	h) The waterproof coating can be applied onto the outside surface of the grouting only after satisfaction of the test result.

1. 抆泥試水:

1.1 時間: 在做外牆批盪前

1.2 方法: a) 抆泥後隔3日可安排試水

b) 用氣壓水壺, 約以每分鐘2米的速度, 直接將水沿著抆泥位置外層射水;

c) 試水由窗底開始, 再往兩邊窗側邊, 由上至下, 最後測試窗頂.

1.3 檢查 d) 檢查抆泥的內面有否漏水或水影, 如沒有滲水, 表示抆泥質素沒問題

e) 如有, 紀錄位置, 修補後重複步驟 “b” to “d”.

f) 如果經過第二次測試仍然滲水, 便要將所有抆泥凿去, 重新抆泥後再做測試.

g) 雙方試水滿意後, 才可以讓分判商將防水油塗上外層表面.
