Installation of a waterproof membrane will help reduce this phenomenon, where salt and minerals migrate to the exterior finish material.

99
Q

Issue with too much water in concrete

A

Makes it easier to work, but causes excessive water, which manifests in cracking, leakage, and absorption. The water is trapped in the concrete and has to go somewhere, so it typically escapes to the interior of the building.

100
Q

Issue with water and a water-based flooring adhesive

A

This will result in floor material lifting.

101
Q

Two waterproofing methods

A
  1. Water Seal: monolithic; prevents any water from entering

Q

Advantages of sheet membranes

Limitations of sheet membranes

A
  • Arrive to jobsite with uniform thickness, strength, and quality
  • Immediate setting
  • Good insulating properties
  • Low risk of failure if installed properly

106
Q

Types of liquid membranes

Advantages of liquid membranes

Limitations of liquid membranes

A
  • Hot liquid asphalt or cold asphaltic compounds
