Stormwater Drainage & Subsoil Drains
Stormwater Drainage & Subsoil Drains
Protect your Property, Protect Your Peace of Mind
Persistent runoff water, pooling, soggy lawns, and damp foundations can lead to costly structural damage.
Alpha Plumbing’s PIRB-registered plumbers have over 35 years of experience in professionally assessing, designing, and installing tailored drainage solutions that safeguard properties for the long term.
Why Drainage Matters
Through years of work in Gauteng, we’ve seen how seasonal downpours and clay-rich soils contribute to drainage issues, which, left unchecked, can lead to:
- Weaken building foundations leading to structural cracks
- Damage paving, driveways and landscaping
- Cause mould, damp and foul odours
- Reduce long-term property value
- Waste rainwater that could otherwise be harvested and reused
Proper drainage is not cosmetic—it's structural. Alpha Plumbing goes beyond surface fixes. Through professional assessment and design, we deliver tailored drainage solutions that protect your property and support uninterrupted living.

Helpful Tips & Advice on Stormwater Issues
Even before drainage problems become obvious, there are steps you can take to protect your property:
Walk your property after a downpour. Standing water near walls, foundations or paving often points to hidden issues.
Damp smells, mould near skirting boards or cracks in paving are often drainage-related, not just cosmetic.
Blocked or misaligned gutters can overload stormwater systems, causing overflow and pooling.
Adding soil, paving or garden features without considering slope can unintentionally trap water.
The longer water sits, the higher the risk of damage to foundations and underground pipes. Prompt action usually means a simpler, more affordable fix.
