Comprehensive Moisture Defence for Every Structure
Water infiltration is one of the most damaging and expensive problems a property owner can face. Whether it manifests as damp basement walls, pooling water on a flat roof, or hairline cracks that let moisture seep into your foundation, the consequences compound quickly: mould growth, structural weakening, and a significant drop in property value. ClearFlow Plumbing & Waterproofing provides end-to-end waterproofing solutions engineered for the Houston climate and its unique soil conditions.
Our interior waterproofing systems are designed to manage water that has already entered the structure. We install perimeter drainage channels, sump pump stations, and vapour barriers that redirect moisture away from living and storage spaces. Each system is tailored to the layout and water table conditions of your property, and our sump pumps include battery backup units so protection continues even during power outages.
For new construction and major renovation projects, exterior membrane waterproofing offers the most robust defence. Our crews excavate down to the footing, apply a multi-layer membrane system, and install drainage boards that channel groundwater to a French drain or storm sewer. The membrane bonds directly to the foundation wall, creating a continuous, impermeable barrier rated to withstand hydrostatic pressure for decades.
Foundation sealing addresses the micro-cracks and porous joints that allow moisture to migrate through concrete and masonry. We use injectable polyurethane and epoxy resins that expand within the crack, forming a flexible, waterproof seal that accommodates the natural movement of the structure. For flat and low-slope roofs, our elastomeric roof coatings reflect UV radiation, reduce surface temperatures, and create a seamless waterproof layer that extends the life of the underlying membrane by ten years or more.
Interior Waterproofing
Perimeter drains, sump pumps with battery backup, and vapour barriers keep basements and crawl spaces dry from the inside out.
Exterior Membrane Systems
Multi-layer membranes bonded to foundation walls create a permanent barrier against groundwater and hydrostatic pressure.
Foundation Sealing
Injectable polyurethane and epoxy resins fill cracks and porous joints, stopping water migration through concrete and masonry walls.
Roof Coatings
Elastomeric coatings seal flat and low-slope roofs, reflecting UV radiation and adding up to ten years of waterproof protection.
