D6135-05 – Standard Test Method Technical Guide
📐 Scope and Application Framework
This standard practice, designated ASTM D6135 – 05, covers the minimum installation recommendations for self-adhering modified bitumen sheets used in waterproofing. The practice is intended to supplement, not replace, detailed instructions from the designer or system manufacturer and applies exclusively to new installations.
For the purpose of this practice, the substrate must be structurally sound, sloped to drain, capable of accepting the weight of the membrane and system materials, and compliant with local building codes. Similarly, all system components must meet applicable federal, state, and local environmental regulations. The standard explicitly excludes additional plies of membrane, expansion joints, insulation, and drainage layers from its scope.
📦 Material Delivery and Storage Protocols
Section 5 of the standard requires that all materials be delivered in the system supplier’s unopened containers and packages. Every package must be clearly marked in a weather-resistant manner with the type, stock, and lot number.
Specific storage conditions are mandatory for preserving material integrity, as outlined in Section 6:
| 📦 Material Component | 🟦 Required Storage Position | ⚡ Key Parameter |
|---|---|---|
| Boxed Sheet Materials | Horizontal | Prevents roll deformation and edge damage. |
| Unboxed Sheet Materials | Vertical | Elevated off the ground; protected by waterproof covering. |
| Primer, Mastic, Surface Conditioner | N/A (Sealed Containers) | Maintain at supplier’s specified temperature range. Protect from moisture and ignition sources. |
🔗 Referenced Standards and Guidelines
ASTM D6135-05 relies on a suite of complementary standards to ensure a complete and durable waterproofing assembly. Adherence to these referenced documents is critical for proper detailing and performance verification.
| 📘 Standard Designation | 🎯 Purpose and Application |
|---|---|
| ASTM D 1079 | Provides standard terminology for roofing, waterproofing, and bituminous materials. |
| ASTM D 5295 | Guide for preparation of concrete surfaces for adhered membrane waterproofing systems. |
| ASTM D 5898 | Guide for standard details (flashing, terminations, and penetrations) for adhered sheet waterproofing. |
| ASTM D 5957 | Guide for flood testing horizontal waterproofing installations to verify system integrity. |
| FM Global 4470 | Approval standard for roofing and waterproofing assemblies (property loss prevention). |
💡 Practical Tip: Always cross-reference the project’s substrate conditions with Guide ASTM D 5295 before commencing membrane application. Proper surface preparation is the single most critical factor for the long-term success of adhered waterproofing systems.
⚠️ Design Limitation: This practice does not cover the design or installation of drainage layers, insulation, or expansion joints (Section 1.2). These elements require separate engineered details and are outside the scope of this standard.
❓ Frequently Asked Questions
🔍 What is the designation and scope of this standard?
The standard is designated D 6135 – 05. Its scope covers the minimum installation recommendations for self-adhering modified bitumen sheets in waterproofing applications, assuming the substrate is structurally sound, sloped to drain, and compliant with local codes.
💡 How should unboxed modified bitumen sheets be stored?
According to Section 6.1, unboxed sheets must be stored in a vertical position, elevated off the ground, and placed under a protective waterproof covering to prevent contamination of the sheet surfaces.
⚡ What are the environmental regulations requirements?
Section 1.2 states that all components of the waterproofing system are assumed to comply with any federal, state, and local environmental regulations which may be in effect at the time of installation.
📌 Which standard provides guidance for flood testing?
ASTM D 5957, Guide for Flood Testing Horizontal Waterproofing Installations, is the referenced standard for verifying the watertight integrity of the installed system.
