What's the difference between surface and subsurface drainage systems?

Surface drainage handles water on top of the ground using channels and slopes, while subsurface drainage removes water below ground through pipes and perforated systems. Choose surface drainage for areas with heavy rainfall or pooling issues, and subsurface for waterlogging in soil or foundation protection.

How do I know what pipe diameter I need for my drainage system?

Pipe size depends on the water volume you need to handle—larger areas and higher rainfall require bigger diameters, typically 100mm to 300mm for residential use. Check local building codes and calculate your catchment area to get the right size, or consult a surveyor if you're unsure.

What's better for sandy versus clay soil drainage?

Sandy soil drains naturally, so you may only need gravel or minimal pipe systems, while clay soil requires proper drainage pipes and aggregate layers to prevent waterlogging. In the UAE's mostly sandy conditions, focus on slope and collection systems rather than heavy subsurface work unless you're on clay-rich plots.

Should I invest in permeable paving or traditional drainage channels?

Permeable paving works for light drainage and looks modern, but traditional channels handle heavy water flow better and are more cost-effective for serious drainage needs. Choose permeable paving for decorative outdoor areas and standard channels for driveways or areas prone to pooling.

How often does a drainage system need maintenance, and what's involved?

Most systems need clearing once or twice yearly, especially after heavy rain, to remove debris and ensure pipes stay unblocked. Regular inspection for cracks or settling saves money by catching problems early before they cause foundation or flooding damage.
