Superior Waterproofing

AM Shield Waterproofing Corp. features Tremco sealants for foundation membranes. The benefit of these time tested membranes are their ability to expand and contract with normal foundation movement and maintain it’s permanent bond to the foundation eliminating water penetration. Materials such as “tar” do not have flexible properties and water can penetrate behind the membrane and cause seepage soon after installation.

Another common method of waterproofing would be “panels” that are filled with sodium bentonite and hung on the foundation wall. The bentonite, when introduced to water, expands and seals the foundation. In some cases the expansion process pushes the product off the wall causing voids behind the membrane and an ultimately failure will occur.

Homeowners should use common sense when hiring a contractor to do exterior waterproofing. Safety must play an important role in this process. Improper excavation and backfill can lead to personal and/or structural damage. Contractors should be licensed, insured and follow OSHA and local regulations regarding excavation.

Foundation Excavation

• Property is marked out to locate all utilities buried in the area.
• Surrounding areas are protected prior to excavation.
• Foundation wall is excavated to the depth of the footing.
• Foundation wall is cleaned and inspected.

Foundation Damage

After excavation certain foundation walls can be found in this condition. Years of water penetration, freeze, thaw and settlement can damage a foundation making structural repair necessary.

Foundation Repair

When a foundation is found in poor structural condition all loose or deteriorated concrete is removed. A bonding agent is applied to the foundation and a high performance mortar repair is installed to the foundation wall prior to applying a
waterproofing membrane.

Trowel Applied Waterproofing Membrane

• Installed after repairs are made to foundation wall.
• Single Component, Rapid Curing, Fluid Applied, Elastomeric Waterproofing Membrane.
• VOC compliant
• Can be applied to green or damp concrete.

Spray Applied Waterproofing Membrane

• Property is marked out to locate all utilities buried in the area.
• Installed after repairs are made to foundation wall.
• Polymer-enhanced, single-component, fluid-applied waterproofing membrane.
• Designed for spray application to concrete, masonry and other structural substrates, primarily in vertical installations.
• Can be applied to damp or green concrete.
• VOC compliant

Protection Board

Protection course of 3/8” to 3” foam protection board is applied over the membrane to protect it against damage caused by backfill.
