摘要历史建筑的长期性能会受到许多环境因素的影响，其中一些因素随着结构性能的恶化而变得更加明显。许多高大的历史建筑在遇到大雨时都会进水，特别是英格兰西南部的教堂塔楼。重要的是要认识到，渗漏不仅可以通过建筑物屋顶的缺陷发生，而且可以通过固体砌体的显著厚度发生。确定最适当的干预措施需要了解水可能进入结构的方式，并评估潜在的修复方案。虽然完整的工作时间表使用了综合评估，涉及实验室，现场和档案工作，以评估可能对这些固体墙结构进行的维修，本文重点介绍了实验室工作进行通知写作的技术咨询说明风驱动的雨水和水分运动的影响，在历史建筑。实验室工作表明，灌浆和粉刷可有效减少水渗透，而不会延缓干燥速率，使用内部灌浆也具有非常有益的效果。
Abstract Long-term performance of historic buildings can be affected by many environmental factors, some of which become more apparent as the competence of the fabric deteriorates. Many tall historic buildings suffer from water ingress when exposed to driving rain conditions, particularly church towers in the SW of England. It is important to recognize that leakage can occur not only through flaws in the roof of a building but also through significant thicknesses of solid masonry. Identification of the most appropriate intervention requires an understanding of the way in which water might enter the structure and the assessment of potential repair options. While the full work schedule used an integrated assessment involving laboratory, field and archival work to assess the repairs that might be undertaken on these solid wall structures, this paper focuses on the laboratory work carried out to inform the writing of a Technical Advice Note on the effects of wind-driven rain and moisture movement in historic structures. The laboratory work showed that grouting and rendering were effective at reducing water penetration without retarding drying rates, and that use of internal plastering also had a very beneficial effect.
