Basement Construction Joints
Construction joints are a particular weak points in basement structures through which water can penetrate. Therefore, joints between components, including day work joints, should be durable and watertight and include appropriate waterstops (Vandex Expaseal) or hydrophilic strips. Kickers, usually cast as part of the slab, should be used to form the joint between floors and walls (NHBC Chapter 5.4).
The above design should detail proprietary components for waterproofing complex junctions in basement waterproofing projects.
Any basement design should also include the correct method and details to form all joints and junctions when using cavity drainage membranes. This design ensure junctions are correctly lapped and sealed in accordance with the manufacturer’s recommendations. This includes the junctions between:
Waterproofing system and superstructure damp proofing
Horizontal and vertical waterproofing
Waterproofing components
