PIONEER® CrystalGuard™ 400D
Innovative Dry Shake Crystalline Waterproofing Powder
What Is CrystalGuard™ 400D Waterproofing Powder
PIONEER® CrystalGuard™ 400D is a high-performance crystalline waterproofing powder specifically formulated for dry-shake application on fresh concrete surfaces. As an advanced dry shake waterproofing material, it penetrates the concrete structure to form a network of insoluble crystals that block water pathways and resist hydrostatic pressure. This treatment is designed to help reduce water penetration into concrete. Performance depends on substrate condition, application, curing, and exposure conditions.
Key Features of CrystalGuard™ 400D
-
Crystalline Action: Designed to promote crystalline formation within concrete pores and capillaries to help reduce water penetration.
-
Dry-Shake Application: Formulated for application to fresh concrete surfaces.
-
Surface Integration: Incorporated into the concrete surface during finishing, following the specified application procedure.
-
Application Guidance: Follow the current Technical Data Sheet for application rate, timing, finishing, and curing.
CrystalGuard™ Integral Crystalline Waterproofing Technology
CrystalGuard™ Integral Waterproofing is the result of PIONEER®’s 24 years of technological innovation, using crystalline waterproofing technology to achieve self-healing of concrete cracks and inherent waterproofing of concrete structures. This technology redefines the concept of building waterproofing and brings an intelligent dimension to concrete.
The related technologies of CrystalGuard™ have earned over 20 patents and received national recognition, including the Second Prize of the National Science and Technology Progress Award and the First Prize of the Ministry of Education Science and Technology Progress Award. Long-term waterproofing performance depends on the concrete design, workmanship, curing, crack characteristics and exposure conditions. Assess suitability using current product-specific test reports and project requirements.
Technical Advantages of CrystalGuard™ 400D
-
Deep Penetration: The crystalline structure penetrates deeply into the concrete, offering complete protection.
-
Hydrostatic Resistance: Effectively resists hydrostatic pressure, making it ideal for structures exposed to water.
-
Self-Healing Properties: Reactivates in the presence of water, sealing minor cracks for continuous protection.
-
Environmentally Friendly: Suitability for direct drinking-water contact must be confirmed against applicable project and regulatory requirements and any required drinking-water-contact certification.

PIONEER® CrystalGuard™ 400D Dosage & Mixing Instructions
-
Usage: PIONEER® CrystalGuard™ 400D is applied at 2.8-3.7lbs./yd². Evenly sprinkle the powder using a special sieve on-site.
-
Application: For the underside of flat concrete structures (e.g., basement slabs), sprinkle the powder 1-2 hours before concrete pouring. For the top side (e.g., basement roof slabs), sprinkle and trowel before the concrete initially sets.
-
Curing: Follow relevant standards for concrete construction. After final set, ensure proper moist curing for at least 14 days.

FAQ
CrystalGuard™ 400D is a dry-shake crystalline waterproofing powder designed for application during fresh-concrete construction.
No. CrystalGuard™ 400 is the water-mixed crystalline coating/slurry product. CrystalGuard™ 400D is the dry-shake product used with fresh concrete.
CrystalGuard™ 400D is primarily intended for fresh-concrete application. Retrofit use should only be considered where the approved construction or repair sequence provides the fresh-concrete condition required by the product procedure.
Current public product information indicates 2.8–3.7 lb/yd². Confirm the current rate, metric equivalent and application-specific limits from the verified Technical Data Sheet before estimating project quantity. (www.pioneerfibre.com)
For underside applications, apply the product during the approved pre-placement construction stage. Current public information refers to a 1–2 hour interval before concrete placement, which should be confirmed against the current application guide before field use. (www.pioneerfibre.com)
