Denver mid-rise employs unusual dewatering method for foundation

July 16, 2018

One of Denver’s first cross-laminated timber (CLT) mid-rises has employed a rarely utilized means of groundwater control, known as ejector well dewatering. One of the benefits of this system is ability to lower groundwater to the maximum extent possible, allowing for the excavation and installation of the foundation mat slabs and waterproofing membrane in “near-dry” conditions.

December 13, 2017

Auditoriums and computer rooms that do not require daylight now occupy basements that formerly housed mechanical plants and vehicle parking. These sensitive occupancies require the spaces be waterproofed to prevent water from migrating through the basement walls and slab in contact with the wet, adjoining soil.

Vapor intrusion occurs when there is a migration of chemicals containing vapor from a subsurface source such as soil, groundwater, or soil vapor into an overlying building (Figure 1). As a result of past activities, some areas are more prone to the risk of vapor intrusion for its surrounding structures.

Construction Dewatering: Understanding its effect on below-grade waterproofing

July 29, 2016

Construction site dewatering is used to locally control and lower groundwater levels in the vicinity of the excavation. This is typically done to maintain soil conditions needed during, and occasionally after, construction—for example, to keep soil dry enough for construction loads, installing building materials, or safe working conditions.
