1 Basements are Changing John Straube, Ph.D., P.Eng Basements: New & Retrofit Energy Efficient, Durable, Healthy Increasingly used as living space Not a root /coal cellar anymore! High quality space expected - new and retrofit Owner can finish herself Low cost for high density sites (cities) Can now locate laundry, heating, hotwater elsewhere Modern basements are different they need different approaches! Commercial basements are similar Building Science Corporation presented by Basements No. 2/73 Basements Part of the Enclosure Basements Below grade enclosure Includes floor slabs, practically need to include transition Separates exterior (soil/air) and interior Functions of all parts of the enclosure Support heavy lateral loads Control less temperature, more water Finish (usually) Basements No. 3/73 Basements No. 4/73 Straube buildingscience.com 1 of 21
2 Moisture: Old ideas CBD# Drainage layer Exterior moisture barrier Exterior insulation Air barrier Exterior insulation Drainage layer Capillary break Air tightness Control: Moisture Moisture causes most failures Mold (musty basement smell) Decay (especially rim joist) Staining /Paint peeling Floods and leaks, eventually causing the above Salt damage to masonry old basements Where does moisture come from? 1. Exterior 2. Built in 3. Interior Basements No. 5/73 Basements No. 6/73 1. Exterior Environment Moisture Sources 1. Precipitation 2. Rainwater shedding 3. Surface water Run-off 5. Sub-surface Moisture - Groundwater - Vapor 4. Water vapor Solutions: Minimize Rain loads Provide Good Shedding Provide Good Drainage Provide Capillary Breaks 1. Controlling Exterior Moisture Sources Same approach as above-grade rain control Deflection Overhangs, slopes, gutters Drainage/Exclusion/Storage Three strategies for the enclosure Drying Remove built-in incidental moisture 5. Sub-surface Moisture 5. Basements No. 7/73 Basements No. 8/73 Straube buildingscience.com 2 of 21
3 Control Exterior surface water Surface Drainage First step Common problem Overhang Gutters Downspouts Sloped grade Perimeter drain Basements No. 9/73 Basements No. 10/73 Solution Problem Basements No. 11/73 Basements No. 12/73 Straube buildingscience.com 3 of 21
4 Basement Enclosure Strategies Exterior surface water Drainage wont help here Damage recovery Basements No. 13/73 Classification of Groundwater control 1.

Backfill not necessarily free draining B. Drainage crushed stone A. Screen optional (similar to cladding---shed and screen liquid moisture-rain and groundwater) Collector and Removal Drain Interface with undisturbed below grade environment Basements No. 17/73 Barrier (1) Below-Grade Enclosure Wall System No Drainage hydrostatic pressure developed A. Positive side Waterproofing B. Concrete or masonry C. Insulation heat flow control (int. option) D. Interior finish Perfect barrier: drainage system can be used to reduce hydrostatic pressure waterproofing layer resists significant head of water Above Grade Level Below Grade Level Backfill not necessarily free draining B. Drainage (opt) crushed stone Collector and Removal Drain A. Screen optional (similar to cladding---shed and screen surface moisture-rain) Interface with undisturbed below grade environment Must use waterproofing below water table! Slab? Connection? Lowers water table, reduces hydrostatic pressure Basements No. 18/73 Barrier (2) Below-Grade Enclosure Wall System No Drainage hydrostatic pressure developed A. Negative side Waterproofing B. Concrete or concrete masonry C. Insulation heat flow retarder (int. option) D. Interior finish Perfect barrier : drainage system to reduce hydrostatic pressure waterproofing Above Grade Level Below Grade Level Backfill not necessarily free draining A. Screen optional (similar to cladding---shed and screen surface moisture-rain) Interface with undisturbed below grade environment Storage (1) Below-Grade Enclosure Wall System Limited ability to resist moisture loads A. Rubble or concrete masonry (storage) B. Usually no insulation to allow drying C.
