ASTM D5898/D5898M-96(2005)e1

Standard Guide for Standard Details for Adhered Sheet Waterproofing

SIGNIFICANCE AND USE
This guide illustrates general details for below grade and plaza waterproofing. It serves as a guide that will enable the designer to prepare complete waterproofing details for each specific condition that occurs on a project.
SCOPE
1.1 This guide covers details for typical conditions encountered in adhered sheet waterproofing on below grade structures and plazas.
1.2 This guide does not cover liquid applied waterproofing.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

5. Drawings
5.1 This guide is not all inclusive. The designer should detail all typical and special conditions on the project, paying particular
attention to transitions in plane and intersection of different details.The applicator should provide shop drawings of each condition
to confirm field conditions and to verify his understanding of the design intent.
5.2 Waterproofing membranes and reinforcement are indicated on the figures as a single thick line, regardless of the number of
plies.
5.3 Protection layers have been omitted for clarity. See Section 6.
6. Protection
6.1 Protection materials are required over all waterproofing to prevent damage from backfill, reinforcing chairs, and
construction traffic, unless the membrane system incorporates an integral protection layer. Protection also is required where
membranes terminate above grade and may be exposed to ultraviolet light.
6.2 Materials for protection include: asphalt composition boards, plastic drainage panels, low density expanded polystyrene
boards, and extruded polystyrene insulation. Low density expanded polystyrene boards and some types of plastic drainage panels
are not suitable for protection on horizontal surfaces. Protection materials are loose-laid on horizontal membranes and attached to
vertical membranes with compatible adhesives. They should be installed as soon as possible after the membrane, or each portion
of it, is completed or water tested.
7. Reinforcement
7.1 Reinforcement is required for built-up and modified bitumen membranes at transitions, such as internal and external corners
and at static concrete construction joints and cracks. Reinforcement also is required where reinforcing bars, pipes, and conduits
penetrate the membrane. Separate reinforcement generally is not required for polymeric and vulcanized elastomeric membranes.
7.2 Reinforcement usually is installed before the membrane but may be applied over it. Refer to the membrane manufacturer
for details.
7.3 The minimum reinforcement is one ply. Systems using a multiple ply membrane usually require two or more reinforcement
plies, whereas single ply modified bitumen systems generally require one.
7.4 When additional plies are used as reinforcement, they should extend at least 150 mm (6 in.)[6 in.] beyond the corner or
penetration and each succeeding ply should extend 75 mm (3 in.)[3 in.] beyond the previous ply.
7.5 Where reinforcing bars penetrate waterproofing, such as at rock anchors and wall to slab transitions, they should be sealed
with reinforcing plies finger cut around the bars or liquid applied membrane or both.
7.6 Some manufacturers require cementitious cants or a liquid applied waterproofing or mastic fillet at reentrant angles,
chamfered external corners, and other special conditions to be implemented during construction. These should be indicated on
project details.
7.7 Detailsshouldrecognizethenormalsequencingofconstruction.Foundationwallsmaybecastbeforeorafterslabsongrade.
Structural slabs are cast after walls. Waterproofing of individual elements frequently follows this sequence, for example, walls are
waterproofed before the structural slab is cast. The resultant cold joints may be dynamic.
8. Penetrations
8.1 Flashing at penetrations should accommodate differential movement between the slab and the pipe, conduit, or drain. For
built-up and modified bitumen membranes, lead reinforcing is recommended where pipes or drains are installed in sleeves but is
optional where they are cast into the wall or slab. Cast iron drains, cast into the slab with flanges flush with or slightly below the
slab, are preferred. Additional plies of reinforcement should be installed at drains.
8.2 Wearing courses on plaza decks move differentially from the structural slab. To prevent damage to the drainage system or
flashing rupture from this movement, drains should be installed in the structural slab with inlets in the wearing course divorced
from the drain body.
9. Expansion Joints
9.1 Structural expansion joints should be designed to permit independent movement of structural elements on each side of the
joint. Control joints should be located to permit non-reversible movement and may be dynamic.The size and location of expansion
and control joints should be determined by the structural engineer. Expansion joint covers should be designed to maintain
continuity at all changes in plane. They should be designed to prevent displacement when subjected to water pressure. Where they
occur in elevated slabs, they should be raised above the surface. Control joints are not detailed as expansion joints but should be
reinforced in all membrane systems.
10. Structural Items
10.1 Water stops, keyways, and other structural elements that are frequently installed in construction and control joints are not
indicated on the details.
