Drainage around concrete

 A good drainage system collects and disperses surface water.  Drainage considerations should include around patios, swimming pools, across driveways, along pathways and retaining walls, in fact any area where surface water collects.

Why is drainage so important?

Insufficient drainage on sidewalks, patios, driveways, retaining walls and foundations causes damage to the structure of concrete.  As a direct result the water places intense pressure on the foundations that eventually leads to cracking and damage.  Further side effects of poor drainage is the area becomes a breeding ground for mosquitoes and mold.

Planning your drainage

It is crucial that in the planning stages of a patios, paths, retaining wall or a driveway that the area is sloped slightly.  Having a slight slope (or ‘fall’) provides a method for the concrete to drain the excess water that collects on top.  Ideally, this water should drain off the concrete away from the foundation of your home.

Sometimes, it might not be enough simply to let the water drain away in which case a drainage channel is built to collect the surface water, and direct it to a dispersal point which leads to a storm water pit or an existing surface water drain or soak-away.

ICR Concrete Supplies have locations in Albion Park for Shellharbour residents, Wollongong and  also Mittagong  allstocking a large range of drains and pits for all your drainage requirements.  They also offer delivery.  Below are the most common products they sell for drainage.
