Stopping a leak often requires more than just product; it requires the right technique. Here's how to approach common waterproofing tasks:
Preparation is Key
Always clean the surface thoroughly. Wire brush concrete and remove old, loose caulk from windows. Most sealants fail because of poor adhesion to dirty surfaces.
Check the Grade
Before buying products, ensure the ground slopes away from your foundation. Sometimes the best "leak sealer" is simply a shovel and some dirt.
When to Call a Pro
If you see large structural cracks (wider than a pencil) or if water is pouring in during every rain, it may be time to consult a waterproofing contractor.
