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 solution ensures superior protection against water ingress, enhancing the durability and lifespan of concrete surfaces.

Key Benefits of CrystalGuard™ 400D
-
Advanced Crystalline Technology: Reacts with moisture and free lime to form insoluble crystals, ensuring effective waterproofing.
-
Dry Shake Application: Ideal for fresh concrete, simplifying the application process and ensuring consistent performance.
-
Durable Surface Protection: Offers superior resistance to water ingress, chemical attack, and freeze-thaw cycles.
-
Permanent Waterproofing: Becomes an integral part of the concrete, providing long-term durability.
CrystalGuard™ Integral Crystalline Waterproofing Technology
CrystalGuard™ Integral Waterproofing is the result of PIONEER®’s 22 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. CrystalGuard™ overcomes the limitations of traditional flexible waterproof materials, such as aging, blistering, difficulty in construction, and challenging maintenance. Its waterproofing lifespan matches the structure’s lifespan.

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.
