通常情况下，我们的水泥外墙出现防水层损坏、水泥砂浆空鼓、墙体缝隙三种情况会导致渗水情况，那么遇到这种情况改怎么处理呢？我们一起往下看看吧！
防水层损坏
若外墙渗水是因为防水层出现了损坏导致的，并且渗水面积比较小的话，则应该先将渗水位置铲除平整，然后在渗水位置重新涂抹一层防水材料，防水材料施工合格且干燥以后，还需要在墙面上涂刷一层水泥砂浆或者是铺贴新的瓷砖。
水泥砂浆空鼓
若外墙渗水是因为水泥砂浆层出现了空鼓现象导致的，则应该将水泥砂浆层铲除干净，再使用聚合物水泥砂浆进行修补。
墙体缝隙
若外墙渗水是因为墙体出现较宽缝隙导致的，则应该使用无机防水堵漏材料进行堵漏和填平。相反假如缝隙比较窄的话，应该使用聚氨酯防水涂料进行涂刷和填充，实现堵漏目的。
注意：外墙渗水原因和位置不同的话，采取的解决办法也会不一样，大家在选择解决办法之前，一定要先把外墙渗水的原因和具体位置找出来。若自己不会处理，则应该请专业人士帮忙。发现外墙渗水的时候，一定要及时进行处理，千万不要选择错误了。
注意事项
1、对外墙进行防水施工的时候，一定要确定清楚室外的天气温度是多少，一般情况下吗，室外的天气温度最好不要超过三十五度或者是低于十度，若是低于十度的话，则不适合进行外墙防水施工，应该等天气暖和一点了再施工，若强行施工的话，则会导致防水层被冻住，影响到防水效果，降低使用寿命。
2、为了确保外墙防水的施工效果，建议大家最好是在春天或者是秋天的时候进行防水施工，这样室外天气温度就不会太高或者是太低。此外，施工之前，一定要提前根据正确的比例将防水材料搅拌好，并且一定要搅拌均匀。
