Basements are a rare feature in modern day homes but are quite prevalent in older homes in the more established leafy suburbs of Johannesburg. Historically, it is due to the ample land available in Johannesburg that basements did not feature or become popular. Nowadays, in houses, these basements have often been converted into wine cellars, home movie cinemas or family rooms, adding significant value to your home.
What causes your basement to leak?
Understanding why your basement may be experiencing high levels of damp and moisture, we need to consider the geographical characteristics of Johannesburg. Parts of the city have an incredibly high water table, evident during the construction of the Gautrain tunnels, which revealed the area’s significant water saturation. Consequently, basements can become indoor swimming pools; ruining finishings, causing damp, mould and structural issues.
Damp and Flooding issues often arise from a variety of causes, including, but not limited to:
- Waterproofing not in compliance with SANS 10021
- Damaged / Ageing Waterproofing
- Inadequate subsoil / below ground drainage and / or changing ground water conditions
- Submersible pump issues
How to tackle a leaky basement?
When the musty smell becomes overwhelming, paint is peeling off the wall or the water is visibly leaking in, it becomes of the utmost importance to rectify the situation.
Inefficient water drainage and waterproofing along with minimal ventilation can all take their toll on your basement.
DIY Tips to Mitigate Basement Leaks:
- Improve ventilation to reduce condensation build up
- Seal exterior cracks, joints and water ingress points where evident
- Confirm your submersible pump and its float switch is working correctly, if you do have one. Additionally, ensure that you have a backup power source for the pump to ensure it’s working during load shedding.
- Ensure that your surface water is properly managed and drains away from the property
- Ensure that you do not have trees growing near below ground drainage lines
However, if these tips don’t resolve the issue, you don’t have to sell your home to avoid dealing with your basement. Basements can be challenging to manage, but with nearly 40 years in the damp and waterproofing business, we’ve encountered and conquered these problems.
