Cold and wet weather can cause leaks and seepage

What happens when it rains in the cooler months?

Because most materials expand when they are heated and contract when they are cooled, concrete will expand or contract slightly with changes in temperature. This means that concrete structures will shrink during the cooler months and as a result, cracks and joints are likely to widen during this time. The cooler season is normally a fairly dry season, so expanding cracks and joints may not cause any issues regarding water ingress. Now that the wet season is extending well into the cooler months, cracks in your concrete slab, cold joints or wall to floor joints that have never leaked in the past, may start to show signs of water ingress when it rains.

Additionally, the soil is already high in moisture from recent big rain events and periods of continuous rainy days. Cold temperature, wet weather, hydrostatic pressure and the lateral pressure from saturated soil can push the excess water into basement slabs, foundations and retaining walls where water can seep through cracks, porous building materials, holes, joints and/or compromised waterproofing.

The La Niña system has an above average chance of lasting into September 2022

Research shows the La Niña system, which began 18 months ago and has bombarded Australia with record rainfall and floods, has an above average chance of remaining present into September. Columbia University’s International Research Institute for Climate and Society and the US Climate Prediction Centre said there was a 63 per cent likelihood of La Nina throughout winter and a 58 per cent chance of the system continuing into spring. So, with the extra rainy weather, that is set to continue through to possibly September, there is an increased risk of experiencing water ingress.

Many properties are feeling the effects of the persisting heavy rainfall we recently have had on the South East Coast of Australia. Fortunately, our leak-sealing specialist technicians deliver industry-leading solutions to leaking buildings and concrete structures that provide reliable, long-lasting results.

During the past few months, the Waterstop Solutions teams in Brisbane and Sydney have demonstrated their passionate dedication and unwavering integrity in everything they do by helping as many as possible as quickly as possible with high quality outcomes in mind.  Prolonged rainstorms have caused many buildings to take in water and we have seen many kinds of situations from minor seepage issues to more distressing situations where below-ground living areas are several centimetres deep in water as well as overflowing lift pits, flooded basements, leaking rooftops, garages and balconies.
