How to prevent and deal with Floods from Rain |

26th Jun 2017 | |

A period of heavy rainfall always leads to floods in properties. Many of these are caused by blocked downpipes and drains, which are often the victims of poor maintenance. We dealt with penetrating damp from saturated walls; flooded warehouses from roof failures and also flooded basement rooms as a result of blocked rainwater drains.

Preventing floods from rain:

  1. Ensure a regular maintenance schedule is in place to clear gutters, downpipe hoppers and floor drains. Checking of silicone seals around windows and doors will help identify potential areas of penetrating damp. Also visual inspections of roofs would be useful if possible, to identify possible areas of water ingress;
  2. Basement rooms in particular require vigilant checking of internal drains and inspection chambers, as these areas are particularly susceptible to causing flooding in the event of a deluge of rain;
  3. Flood barriers should be considered for those areas with potential to be subject to flooding, such as lower ground floor levels and also those properties in low lying areas or near rivers. There are some good products on the market which can quickly be assembled to provide a flood barrier;
  4. Observations of the outside of the property should be made during rains, for example this may show up gutter failures causing spillage of rainwater onto the outside of properties;

How to deal with floods from rain:

  1. There are a broad range of problems that can be caused by rainwater, ranging from floods of basements to penetrating dampness over a longer period of time;
  2. In any clean-up operation, proper sanitising should be considered. Rainwater can bring into properties grey water contamination from outside, as a result of dirt, grease and other organic compounds which can give rise to mould growth if not dealt with properly;
  3. Those building materials that are damaged beyond repair should be removed in order to provide access to the full benefit of dry air from building drying equipment. Other preparation may involve cutting open plasterboard partition walls and removal of floor coverings, or in the case of penetrating damp it may be necessary to remove plaster & render coats from solid walls to expose the structure to faster drying;
  4. A drying program should be setup with a combination of dehumidifiers and fans, to circulate dry air around the affected areas;
