Assess Foundation Issues

Let’s start by examining our cinder block foundation for cracks, leaks, and water seepage to determine the extent of waterproofing required. First, we need to create an inspection checklist to make sure we cover all common issues.

Look closely for any signs of mold, mildew, or moisture damage on the interior walls. These are warning signs indicating areas that may need immediate attention.

Next, we should check for efflorescence—those white, powdery residues on the foundation walls. These mineral deposits suggest water penetration. It’s essential to identify these spots as they guide us towards potential problem areas.

Don’t overlook the grading around our foundation either. Water should flow away from the cinder block walls, so let’s evaluate if the grading is sufficient to prevent water accumulation.

Another vital aspect of our foundation assessment involves inspecting the mortar joints between the cinder blocks. Any deterioration here can serve as entry points for water infiltration.

By identifying these common issues early, we can explore various waterproofing options suitable for our needs. Remember, taking the time to thoroughly assess our foundation now will save us from bigger headaches down the road.

Let’s get started!
