Retaining walls

Design Elements to Prevent Failure

Relieve H2O pressure(for all 3 types of failure)

– Crushed stone – Weeps

Overturning– Cantilevered

Footing– Reinforcing

Sliding– Key

Waterproofing

• Structures Below Ground subject to penetration of ground water

• More extreme, if below H2O table• Two basic approaches to Waterproofing

– Waterproof Membranes, or– Drainage– Generally - both used in tandem

Waterproofing Membranes

• Materials– Liquid or Sheet (Plastic, asphaltic, synthetic

rubber)– Coatings (asphaltic)– Cementitious Plasters & admixtures– Bentonite clay

• Accessories– Protection Board– Waterstop

• Unit of Measure - SF, Mils (thickness)
