这听起来像一个很好的凝聚力的报告。钻洞的存在并不一定表明正确安装回顾化学注入防水层。为了让DPC安装成功,最小的喷射管路应该钻150毫米以上外部地面上面创建一个水平障碍在墙上的高度雨“splash-back”。验船师已经表明,在各领域的情况并非如此,这表明高压燃油管上方的墙可以得到湿——呈现干预无效。
此外,回顾DPC有效,石膏内部应该被移除至少1米或300毫米高于湿的最高记录水平按照BS: 6576年,水泥和石膏换成一个渲染与防水添加剂,或damp-specification salt-resisting石膏。
失败的另一个共同的地方是当内部的墙壁上已经与注入的石膏通过线下——创建一个“潮湿的桥”,湿可以通过石膏厚度和桥梁横向damp-controlling层注入砌砖。
同时,测量表明,回顾cavity-wall-insulation可能已经安装了。如果你想象,水平“damp-controlling-layer”注入两种皮的砖砌的,但这在日后,材料已经进入空腔,可以创建一个“灯芯效应”使潮湿起来毛细管作用的绝缘和桥梁回到上面的砖砌的注入势垒的高度。
不管上面所有的财产应由C.S.R.T.合格的验船师检查。许多承包商和验船师不知道如何区分凝结和上升或穿透潮湿,和提升阅读往往是由冷凝(而不是确实上升潮湿尽可能多的人认为,应该注意防潮课程自1800年代中期以来建筑强制性——首先是板岩,随着沥青前更现代的替代品),即一种改进通风、加热和保温的策略可能是唯一的解决方案。是可能的,这从第一天潮湿可能是误诊,而物理干预在墙上可能是无关紧要的。
第一个数据检查与任何潮湿的调查应该是内部相对湿度和空气温度(允许露点计算),其次是墙表面温度读数证明或反驳从一开始凝结。你也应该找一个黑点的模具在家具和气流减少的地区,除了不透水表面,如uPVC窗框等看看入住率概要文件内的财产。
不管上面所有的,所有的可能性是可以治疗的,和一个详细的调查,一个合格的专家将强调干预可能需要的地方。凝结的诊断经常会导致更少的侵入和明显便宜干预!

嗨

请查看我的评论在括号中你所有的问题。

你好,我们在买房的过程中(建于1920年)。房子已经有防水层做夹具和配件形式表示文档遵循
(试着找出这些可以作为你将知道的程度,还在以前的作品)进行。
然而当我们有我们的购房者调查回来说“腔砖石结构的墙壁(? ?这表明他们惊讶空心墙应该有新的DPC)。一些维修需要墙表面包括一些有缺陷的迫击炮和饱经风霜的砖石足够(直接)。房地产一直受到过去的构造运动的影响,证明一些墙表面开裂和变形。从单个检验运动似乎是长期存在的和似乎没有进步(他们要求你确认这个吗?你不是一个结构工程师,所以我建议你不能评论这从外面。如果他们不满意这个作者的评论然后他们应该寻求一个独立的人能够提供建议的构造运动)。防潮课程(DPC)内置属性防止地面湿气的运动穿过墙壁,防止恶化的内部固定装置和配件以及防止湿气导致高水平的木腐真菌。有钻洞的基础的一些外部墙壁,表明一个注入DPC已经安装在某个阶段。湿被发现在低水平进一步主墙和专家调查整个财产交换合同之前是必需的。 (Are they lower than 150mm – if so it seems reasonable that the walls might be getting damp as a consequence, however as this is a cavity wall the only way it would affect the internal walls was if something was bridging the cavity (check the cavity), alternatively the external wall might not be the source of the moisture. There might be an internal bridging issue or the internally applied DPC might not be effective.) Any structural floor timbers which are in contact with damp masonry are at risk from decay and you should instruct your specialist firm to check the sub-floor timbers for defects and again carry out appropriate remedial treatment as required. (You need to make sure you check the timbers and sub floor and also make sure that the level of the timber floor is above DPC level and the moisture level is normal and not elevated. Is there good ventilation?) DPC's should ideally be 150mm above external ground level. In this case, ground levels are high in some positions and this could lead to bridging, causing dampness to the interior of the building. External levels should now be reduced as a precaution. (Sound advice but you must notify the client that whilst the walls remain damp during the drying out process following removal of high ground level they need to be replastered to protect against damp migration) Condition Rating 3. There is evidence that some cavity wall ties have been renewed and enquiries should be made to establish the extent of repairs and whether any guarantees are available. (I assume the client is investigating this) Untreated areas may require expenditure in the future. There is evidence that cavity wall insulation has been installed. Your Legal Adviser should make inquiries to verify the type of insulation and the existence of valid guarantees. (Stay clear of this unless you want to suggest an external coating (Stormdry and also appropriate re-pointing) could be applied to masonry to protect against water penetration this reducing the risk of insulation getting wet and also reduce the risk of water getting onto and corroding wall ties. This also covers the next section) In some circumstances cavity insulation can cause damp penetration and/or result in accelerated corrosion of wall ties that will require remedial treatment. Properties of this age may not have lintels to support the masonry above the openings. Whilst no signs of distress were noted, lintels may need installing or replacing when renewing doors and windows." (this does not come down to a damp specialist but a builder.) Who would we get to do these investigations and why would damp be detected if a DPC has been installed at some point already? (You know that some damp proof courses are more effective than others – see points above for guidance) Trying to work out how we’d know what’s causing it & any costs to put it right. It also says cavity wall insulation is present & some wall ties have been renewed. Why would cavity wall ties be renewed? (We all know what wall ties have corroded – is this a coastal address? Should CWI (cavity wall insulation) have been installed in the first place if it is coastal?) Does any of this sound bad to the point I should re-negotiate price or pull out? (I think this is clearly for you to decide and not to be influenced by anyone else otherwise it is quite easy to get blamed for something) Any help would be appreciated. Thanks.

不同意注入dpc空心墙。
你说的运动结构。
强烈想(碎片)腔过渡性dpc priveouse运动。
腔隔热,被证明是坏的。和取出。
再猜。
Dpc注入为什么离开所有的圬工指向/未修理的
猜测
从组合好。
糟糕的承包商。
是由Diy猜测工作。
