Basement Waterproofing

Basement waterproofing is important, as basements are especially vulnerable to leaks and water damage.

A basement must be protected from water or moisture, as the smallest of cracks can lead to structural damage if not fixed.

Our team are skilled and experienced in drainage and leaks in basements. We can evaluate and find the right membrane to seal any leaks and fix any drainage issues.

Retaining Walls

Retaining walls are like basements; they need to be waterproof and have the correct drainage.

A retaining wall is usually a structure created by pre-cast or cement blocks supporting a mass of earth on one side. Besides good drainage, the retaining wall needs to be waterproof to reduce the risk of any hydrostatic pressure or instability and movement.

Our team at Webb Waterproofing Services can inspect and provide remedial solutions to address the leaking basement and the type of membrane required.
