Follow the water path through the wall
Polyurethane waterproofing for foundation leaks.
A stain inside the basement may be the end of a water path that starts outside the wall. Relevel evaluates leaks in poured concrete, concrete block and stacked stone foundations. For suitable conditions, single-component polyurethane moves through cracks and voids, reacts with water and helps form a barrier along the treated entry paths.
Signs to look for
Does this sound familiar?
Water through a wall crack
A visible interior leak can be connected to a path through or behind the foundation wall.
Moisture at joints or voids
Concrete block and stacked stone assemblies can have pathways that need a wall-specific assessment.
Staining after wet weather
The location of the stain and the conditions when it appears help the team review the likely entry path.
An interior patch that did not last
Covering a visible stain may leave the route carrying water into the building unresolved.
How Relevel approaches it
Help stop water at its entry path.
Waterproofing uses single-component, water-reactive polyurethane, distinct from the dual-component foam used for lifting. Relevel reviews the wall and water path, plans targeted injection, then seals access points and reviews the treated area.
The right fit matters
Repair where it makes sense.
A possible fit
✓ Water is entering through a compatible foundation wall.
✓ The likely cracks, voids or entry paths can be evaluated.
✓ Targeted injection can reach the areas needing treatment.
Needs a closer assessment
✓ A water source that has not yet been identified.
✓ Conditions requiring drainage work or another repair method.
✓ Structural movement needing assessment beyond leak treatment.
Your questions, answered
Questions about
polyurethane waterproofing.
A few practical details to help you understand the service and your options.
What foundation wall types can Relevel assess?
The service covers poured concrete, CMU or concrete block, and stacked stone foundations where water travels through cracks, joints or voids. The wall condition and entry path determine suitability.
Is this the same foam used for concrete lifting?
Relevel uses single-component polyurethane that reacts with water. Concrete lifting and stabilization use dual-component polyurethane.
Does waterproofing also stabilize a moving foundation?
Leak treatment and foundation stabilization address different problems. If movement is also present, it needs its own assessment so the proposed work does not confuse water control with structural support.
What information helps with an initial waterproofing estimate?
Send photos of the leak or staining, the surrounding wall and the wider affected area. Explain when the water appears and identify the wall type if you know it. Photos are optional, and further evaluation may be needed to confirm the scope.
