Resin Bound Permeable Paving // Aliphatic Polyurethane

Pebble Stone Binder

A high-performance transparent binder matrix engineered to encapsulate clean, dry natural pebbles and aggregates into a seamless, fully permeable paving surface.

Utilizes premium aliphatic polyurethane technology to guarantee long-term UV color stability, frost-thaw flexibility, and puddle-free sustainable drainage for residential driveways and civic landscapes.

Binder Chemistries: UV-Stable Aliphatic PU (Exterior) & High-Adhesion Epoxy (Interior Stone Carpet)
Permeability Performance: Sustainable drainage matrix eliminating standing water and surface hydroplaning
Vehicle Load Rated: Engineered flexibility resisting dynamic ground movement and vehicle shear stress

Supply Flexibility

Dual-Track Supply & Packaging Mode

  • Contractor Project Kits: Pre-weighed two-component resin units precisely proportioned for standard 4-bag (100kg) aggregate batches in forced-action mixers.
  • Factory Bulk Supply: 200L steel drums and 1000L IBC supply for regional distributors, paving contractors, and commercial landscape projects with custom formulation support.
System Options

Chemical Binder Classifications

  • UV-Stable Aliphatic PU: Premium exterior standard. Withstands direct solar radiation, seasonal freeze-thaw cycles, and ground flexure without yellowing or embrittlement.
  • Epoxy Pebble Binder: Cost-effective interior solution designed for climate-controlled stone carpet flooring, showrooms, and enclosed conservatory pathways.
  • Color Pigmented PU Binder: Integrated UV-stable color formulation designed for creative track striping, playground graphics, and synthetic rubber EPDM granules.

Standard Installation & Execution Protocol

Systematic procedure ensuring complete pebble encapsulation, high shear resistance, and permeable void formation.

Phase 1: Subbase Engineering & Moisture Check

Ensure asphalt or porous concrete base is structurally sound, clean, and dry. Aggregates must be thoroughly washed, kiln-dried, and completely dust-free prior to mixing. Moisture on stone surfaces will cause foaming and debonding.

Phase 2: Forced-Action Pan Mixing

Blend resin Part A and Part B with a helical mixer for 2 minutes. Load pre-measured clean dry gravel into a forced-action pan mixer, add the resin blend, and mix for 3-4 minutes until every stone facet is coated with a glossy film.

Phase 3: Rake Spreading & Float Compaction

Transfer coated matrix into wheelbarrows and screed evenly using depth-gauged screed bars. Compact and smooth the surface with a hand trowel lubricated lightly with organic release agent to close surface voids.

Phase 4: Slip-Resistant Cast & Ambient Protection

Lightly broadcast fine crushed glass or white aluminum oxide grit over the wet surface to enhance slip rating. Barricade area for 16-24 hours to prevent early foot or rain damage.

Frequently Asked Questions (FAQ)

Q1: What is Resin Bound Pebble Flooring?

It is a surfacing system in which clean, dry decorative aggregates are thoroughly pre-mixed with an engineered resin binder in a forced-action mixer and hand-troweled as a continuous, joint-free matrix.

Q2: Is resin bound pebble paving permeable?

Yes. When the aggregate grading, binder content, and underlying base are properly designed, water drains through the matrix at over 850 L/m²/min, complying with sustainable drainage standards.

Q3: Which binder is better for outdoor applications?

UV-stable aliphatic polyurethane is the industry benchmark for exterior paving due to its long-term resistance to solar degradation and its flexibility under thermal movement. Epoxy binders should be restricted to indoor or sheltered applications.

Q4: Can I use ordinary unwashed or wet stones?

No. Aggregates must be thoroughly washed, kiln-dried, and 100% dust-free. Moisture reacts aggressively with polyurethane polymers, causing foaming and loss of aggregate bonding.
