Technical performance

Drainage performance is engineered, not assumed.

The bunker must work as a complete hydraulic system: sand, liner, reinforcement, base preparation and drainage all influence how quickly water leaves the playing surface.

Infiltration performance

Optimum water movement through the bunker profile.

The provisional figure shown here is a layout placeholder and must be replaced with the certified test result before publication.

Designed for intense rainfall conditions in Portugal and Spain.
High open-pore structure supports rapid vertical drainage.
Continuous bonded surface avoids seams and local restrictions.

Practical interpretation

Understanding infiltration rates.

There is no single recognised Europe-wide good/bad bunker standard. Our bunker liners have been engineered to provide optimum performance .

<100 mm/hrLow performance and higher ponding risk.
100–200 mm/hrModerate performance vulnerable to contamination.
200–300 mm/hrGood initial drainage for many systems.
300+ mm/hrHigh-performance range, subject to total drainage capacity.
Technical infiltration testing
Whole-system performance

The right number only matters when water can leave the bunker.

A strong laboratory result cannot compensate for blocked drains, an uneven base or contaminated sand. Technical credibility comes from controlling every part of construction.

Sand grading and fines content.
Liner pore structure and installed thickness.
Base falls and surface continuity.
Drain spacing, pipe capacity and outlet condition.
Long-term contamination and maintenance.
Designed for Iberian conditions

Performance through intense rainfall, heat and dry periods.

Portugal and Spain can experience long dry periods followed by short, intense rain events. The construction must remain porous, stable and repairable through repeated cycles.

Rainfall resilience

Rapid infiltration helps reduce standing water and pressure-driven sand movement.

Controlled flexibility

The reinforced structure is intended to accommodate service conditions without becoming brittle.

Reduced material layer

Reinforcement supports performance with a thinner SBR composite layer.
