FAQ
Why does my basement flood during heavy rain?
Basement flooding is often caused by poor drainage, hydrostatic pressure, groundwater intrusion and failed waterproofing systems around the foundation.
What causes hydrostatic pressure?
Hydrostatic pressure occurs when saturated soil and groundwater build pressure against below-grade foundation walls and basement structures.
Do I need waterproofing or drainage?
Most water intrusion issues require both waterproofing and proper drainage systems to help divert groundwater away from the foundation.
Can sump pumps prevent flooding?
Sump pump systems help collect and remove groundwater during heavy rain conditions, reducing the risk of basement flooding and moisture intrusion.
Recent Basement Waterproofing Projects
Pasadena Basement Waterproofing & Drainage Installation Project
This Pasadena property experienced basement water intrusion during heavy rain due to poor drainage conditions around the foundation. After completing the necessary foundation repairs, our team installed a waterproofing system, subsurface drainage and redirected groundwater into the existing sump pump system to help protect the basement from future moisture and water intrusion issues.
La Crescenta Basement Waterproofing & Drainage Installation
This La Crescenta basement experienced serious water intrusion due to missing waterproofing protection along the cinder block foundation walls. Our team performed a deep 6–7-foot excavation, applied a dual-layer waterproofing system and installed a substantial subsurface drainage system designed to divert groundwater safely away from the
